| 99 isuzu trooper 3.5 engine burns oil excessively. i am original owner and regularly serviced per owners manual. at 50k miles, engine oil light turned on 2,500 miles after oil change and was over 4 qts low. engine now at 60k mi and burning approx. 1 qt per 600-700 miles. seems to be common engine defect known by mechanics and owners, but isuzu unwilling to acknowledge problem. though monitoring constantly, i am just waiting for significant engine failure. *tr | |||

| I get frequent oil changes in my 99 isuzu trooper and had just gotten one last month. i had at least 2700 miles before my next one. i was driving down the freeway and i saw smoke coming from my hood and all my dash lights came on like a christmas tree. i pulled over and found out that my engine was on fire. i called the fire dept to put it out and got it towed to my house to later find out that the piston had got thrown from the engine because it locked up due to no oil getting to that piston. so now i have to get a new engine which cost about the same as the car. *tr | |||

| From the time i bought the vehicle when it was only a couple years old, every time i brought the vehicle in for an oil change, they said it was almost empty of oil. i brought it in to a dealer several times since it was under warranty. they could never find the reason for it burning oil. every dealer said it was a common issue with the isuzu, but they could not fix it because they could not find the problem. *jb | |||

| 1999 isuzu trooper runs out of oil. my 1999 trooper that i bought new in february of 2000 and have maintained through regular oil and filter changes every 3000 miles suddenly was found to have no oil in the engine block. the vehicle has never had a low oil problem or never shown any signs of leaking. on may 30th of this year as i was driving up my driveway leaving my house in the morning the oil light flashed on and then went off when i reached level ground. i had recently had the oil changed at 72k and the current mileage was 74.5k so i stopped to check the stick. when i pulled the stick it was dry! after dumping 4 quarts of oil into the vehicle the oil finally registered on the stick! i poured another quart in to make it 5 quarts and couldn't believe the vehicle was still running. there was no indication of over heating and no signs of leakage. i called isuzu to ask them why the oil light didn't come on before the vehicle was bone dry of oil. they stated that the light is a oil pressure light and not a oil gauge. i drove the truck for one week and changed the oil and filter myself just to see the condition of the oil and filter. since then i have logged another 3k on the truck and have found the vehicle burns 1 quart per 500 miles. after reviewing the nhtsa website i found out that i am not alone. apparently isuzu does know of this problem and elects not to inform any of it's customers. isuzu should be held liable for not informing all isuzu trooper owners that at approximately 70k that the 99 trooper could have a catastrophic loss of oil resulting in engine destruction. the manufacturer is also negligent for not having a warning system (like a $2 light) on the dash that tells you when your oil is low. i would like to sell or trade this vehicle, however in good conscience i don't think some unsuspecting person should get saddled with this unfortunate condition.

| I took my '99 isuzu trooper for its regular oil change at almost 3000 miles to jiffy lube in colorado springs, co on the 10th of may 2005. while in the bay of jiffy lube the workers' replaced the air filter, oil filter and topped off all other fluids. when asked to turn vehicle on, i turned the key and there was a loud clunk sound and i immediately turned engine off and asked workers' what was that noise and they responded by saying they didn't know and that nothing was wrong. they proceeded to put more oil in the engine, approximately another 3/4's of a quart and told me to take care of the charges for the oil change, which i did. my vehicle was moved outside and left with the engine off. when i started it, there was a mild to moderate rapping noise. i proceeded with my activity and on my way home i stopped at another jiffy lube because the noise seemed to be getting loader and they checked it and said that the oil was full and that it sounded like something in the engine rapping. i drove home and parked it overnight. the next day i drove it to town again and the noise was still there. on the next day i went to drive it to town and after starting it and driving approximately 1/4 mile the engine lite came on and white smoke poured out of the exhaust and filled the cab. i turned around and took it home immediately and it has been parked for approximately 3 days and today a mechanic from jiffy lube came out and examined the engine and all the parts involved in the oil change and those parts are fine except that the radiator fuild is extremely low and it has use 1 quart of oil already. there are no leaking spots anywhere on the vehicle. he states that it sounds like the head is blown and the metal parts in that area are damaged and that the engine has to be taken apart. it has only 77,000 miles on it and until this time there has been no known problems. | |||

| I own a '99 isuzu trooper. since about 70k miles (about a year ago), it has been burning oil at a really high rate. i have met personally two other trooper owners with this problem who were lucky enough to get new engines out of isuzu, but since i was over the warranty, i don't qualify. now i have read many other similar complaints on the nhtsa site and wonder why isuzu has not been held accountable for this? i cannot afford to replace my engine, nor can i in good conscious trade it in and make it someone else's problem. i am burning 3 quarts of oil for every 300 - 500 miles! i am afraid to take it on any trips to visit family! i feel i am being punished for owning this vehicle and keeping it in good repair! | |||

| 1999 trooper with 3.5l engine. after 60,000 miles i noticed that at regular oil change intervals, @3000 miles, that the engine was buring an excessive amount of oil. after an oil change, i drove from st.louis to kansas city, about 240 miles one way. on the return trip, 60 miles from home, the trooper siezed up. no warning lights, no low oil light, it just quit. i had it towed to the dealer in st.charles and they told me that it had hardly any oil in the crankcase and that the engine was ruined. several months later after listening to the price for an engine from the dealer $9500 and rebuilt engines that would take several months because blocks were not available, i with the aid of a mechanic found a trooper that had been in an accident and replaced the old engine with one that had around 72k miles on it. it burns the same amount of oil!!!!!!! i check it weekly and add to it about the same. isuzu needs to make good on this piece of crap. i'm the original owner and now i couldn't get rid of this thing for 1/25th of what i paid for it, except to someone looking for parts for their soon to be broken down 1999 trooper. | |||

| I took my '99 isuzu trooper to get an oil change, and 3 weeks later the oil light turned on. i went to the isuzu dealership where i bought the car and after checking the oil, they noticed that there are less than a liter in the engine. they filled it and added a conditioner telling me that that should fix the problem. a few months later, driving back from a trip, the engine began knocking and the oil light came on again. moments later i lost power (rpms) and pulled the car over. the mechanic who looked at my car told me (and this was confirmed by a consumer report website) that '99 troopers often have unexplained loss of oil pressure resulting in the engine seizing. the car now needs a new engine (approx 4000-9000 dollars) or a new car. nothing has been done to correct the failure or defect. *tr | |||

| My 1999 isuzu trooper engine seized up. no warning light or any indications that any thing was wrong. towed it to a mechanic and they said it had no oil in it. i had just purchased the vehicle 1 month earlier and had the oil changed/filled immediately after the purchase. i had driven it less than 2000 miles. i now see this problem has been well documented on the internet. now i am having to replace an engine which could be more than the cost of the vehicle because the manufacturers oil consumption defect and lack of low oil gauge/warning. *nm | |||

| I purchased a new trooper in 1999 and did every required maintenance on time at a authorize isuzu dealer. after the 5 year 60,000 mile warranty was up we started taking it to a reputable national oil change company. we never had any indication it was using oil at an abnormal rate. it was not leaking oil, it was not burning oil and the oil light was not coming on. one day the oil light came on and my wife immediately pulled over and we added oil. it would run rough and took it to a mechanic who did some maintenance work. i had not totally wrecked the engine. i got it driving good for about $2,000 and hoped this had fixed the problem. we added and check the oil every 500 miles. two months later the engine seized and i am now told i need a new engine. after searching the internet i have found many others have had this engine oil problem. estimated costs to replace the engine are $4k-$6k which is about blue book for the trooper and now i would have no confidence in putting a 1999 engine with known problems in as a replacement. *jb | |||

| Burning too much oil with absolutely no warning. my check oil light has never come on. have taken it for 3,000 mile oil changes a couple times to find no oil and no trace of oil in it, though i had filled it to where the dipstick registered full within the last seventy miles. i can't make a decent stab at estimating how much it burns because it seems to be fine and then be empty. it doesn't leak anywhere and it doesn't smell like it's burning it, but it's just gone. i have to stay on top of this all of the time; it's a drag. i'm going to go check it now while i'm thinking about it. i am wondering if whatever this defect is affecting my mileage because i only get 16 mpg. my mechanics say the only thing i can do is get the engine rebuilt. i do wish isuzu would help out here. i like the vehicle and am not in a position to have the engine rebuilt or buy another car. i would also feel badly selling this to someone knowing the engine could lock-up with no notice. and if i tell them, who would buy it? *nm | |||

| We bought a 1999 trooper from the dealer that was never registered, but that the dealer had driven for 14,000 miles. we were told by the dealer that a new factory warranty applied as we were the original retail purchaser. after driving this vehicle three years and less than 60,000 miles, the engine froze going up a mountain pass, endangering our lives and our grandchildren's lives. we had the vehicle towed and now have been told that we needed an new engine -- though there was still oil in the engine, there were shards of metal in the oil. (we had properly maintained the engine more than required under warranty but it seemed to burn a lot of oil over the last few months.) isuzu denies that it is responsible, and the dealer denies that they are responsible, so we are now stuck with a vehicle we've had three years that will cost us $5,000 - $8,000 to repair (and that we still owe 11k on and is worth 6k as a trade-in or 8k if we sell it ourselves). i now see other evidence of similar complaints about this vehicle on this site and have talked with other mechanics who have seen similar problems with this vehicle, yet most consumers don't seem to file these reports. i've had several vehicles, and maintain them well, and have never had an engine freeze with 71,000 miles on it. as neither isuzu nor the dealer has been able to provide any assistance nor stand behind their product, i hope that the nhtsa investigates this issue so that no other owners or passengers are placed in potentially deadly and certainly costly circumstances again. *nm | |||

| My orginal complaint #10104322 was submitted 11/04. since then i have paid isuzu and fox motor in grand rapids, mi about $7500 for a new engine. after many attempts isuzu of america would not listen to me and even hung up on me. fox motors was great. they advised the reason my engine froze up is a common problem with this engine. the egr pipe gets clogged with sludge resulting in no oil getting from the bottom to top half of the engine. they advised to have egr pipe cleaned and pcv valve replaced every 15,000 miles or one year. i'd like to sue isuzu of america as i'm out a total of $8,500 due to, what i'm being advised, is a design failure in the early 3.5l v6 engines. it's obvious many others have incurred similar problems. i hope this suggestion by a great isuzu mechanic is helpful to others. fyi, i own two other isuzus (unlucky me!). | |||

| Isuzu trooper 1999 problem after problem, engine burning oil. *bf after the engine was replaced, the engine light illuminated at least 30 times. the dealer gave the consumer all types of excuses until finally they said they didn't know what was causing the light to illuminate. there were other problems such as a hard shift with the transmission, water leaking through the sun roof, difficulty starting the vehicle, uneven tire wear, in just 65,000 the consumer has gone through 3 complete sets of tires. the consumer was told there was a problem with the frame of the vehicle and it could not be aligned. the tie rods were replaced because they were defective. in the past the vehicle lunged forward while the consumer had her foot firmly pressed on the brake. the vehicle intermittently idled high while stopped. the vehicle has rolled backwards while it was in park. another mechanic informed the consumer the previous dealer installed several electrical componets incorrectly and there were also some defective parts that needed to be replaced which caused the engine light to come on. the consumer was getting poor gas mileage. *jb | |||

| While driving 70 mph on a mi freeway, our car engine quit. fortunately we were not in traffic and we were able to coast up an off ramp. aaa trailered the 1999 trooper to a former isuzu dealership who, three days later, advised that the engine froze up and that we would need an entirely new engine. it should be noted that there was oil in the crankcase and that no warning lights went on until after the engine died. we are paying to trailer the car to ks to have it checked by the dealer where we purchased the car and, presumably, the regional isuzu representative. we are the original owners and the car has been serviced regularly; unfortunately, it's past the warranty period/mileage. there is no explanation for this mechanical failure but, a call to isuzu of america, only had them say they've fulfilled their obligation. had the car died in traffic, their been no exit ramp or shoulder, or my wife stranded alone in a desolate place, there could have been serious consequences other than just the financial consequences we now have. fyi, the initial estimate is $7,500 to replace with a used engine provided a good used engine can even be located. *jb | |||

| Engine started normally, then as driving along, momentary power surge and partial stall, accompanied shortly thereafter by engine misfire, and coolant exiting exhaust. turned vehicle off and had towed to dealership. vehicle has approximately 42,000 miles on it and has been well maintained. factory warranty up to 60,000 expired from a time basis a few months ago, and dealer will accept no responsibility for head warpage due to manufacturing defect or improper head gasket installation at factory. replacement cost for new engine is approximately $6700. currently starting a legal claim against isuzu. *ak | |||

| I bought a 1999 isuzu trooper limited edition 1 year ago this month. since buying it i have had the starter replaced, the alternator replaced twice, the small block was bad because of a failure with the dipstick to read the correct amount of oil. my son was involved in a mva due to the fact that the vehicle would not stop as the engine decided to race while he was coming to a slow stop. thank god no one was injured in the accident. the car revs up at an idle at a stop or slowing down position, and now the vehicle is in the garage because the transmission is bad and the alternator went again. the front windshield is not properly sealed and the window fogs up if you don't run the defroster. the draft that comes from the floor on the drivers side is unacceptable. i bought this car with less than 30,000 miles on it and it now has less than 50,000. i really don't understand why a vehicle with this low mileage has so many problems and it is in the shop more than it is out. i expected to have some problems with a used vehicle but not this many and not this costly! i have been reading about many similar problems with this year of trooper and i'm wondering what it's going to take to have the company stand up and take responsibility.*ak | |||

| I own a 1999 isuzu trooper with around 77000 miles on the odometer. i and my family enjoyed the vehicle untill about 1 year ago (10-03) when, on a 250 mile run from san antonio to my home, without any warning lights, strange sounds or rough running, i heard a loud whine from the engine compartment, everything lit up like a christmas tree for a second and then went completely dead. after a long. hot wait and an even longer tow, i had the vehicle checked out and was told that the engine was locked up tight as a drum and that there was around 1 quart of oil in the pan. during my ownership of the truck, i had noticed that the dipstick would occasionally and unexpectedly read low - but it never visibly burned any oil. i chalked it up to a 'dipstick malfunction' and kept up with my oil changes and maintenance. i have owned many classic and high performance vehicles in the past and am a stickler for preventative maintenance. my immediate thought was that my previous oil change had been done incorrectly - but my own diligence in checking the oil prior to my trip and adding a needed quart steered me away from that as a solution. now, after an attempt to locate a replacement engine for the truck online, i find that i'm not alone by any means. being out of warranty (just) leaves me with the belief that i will just have to eat the cost of getting the vehicle back on the road, but i feel that, given the number of similar stories out there, isuzu should pony up and assist those who can prove their stories. after 1 full year without a second vehicle and minus the initial $159 for towing and initial diagnosis, my truck is currently being re-diagnosed and repaired at a trusted facility after a second costly tow. initial estimates have indicated that if a replacement engine is required, i will be out around $3000-$4000 for the engine plus an additional $1000-$2000 in labor. i will lodge a second report once the vehicle has been repaired indicating the accurate total billing. | |||

| I have a 99 trooper with 70k miles on it. the engine starts to burn oil and now it burns 5 quarts of oil within 3 months. no warning light. i heard the ticking sound. when i took it to a garage, i was told the engine was bone dry. this is the second time it happens. last time it runs out of oil in 4 months. i do oil change on a regular 30k miles basis and i do other maintenance too. i feel i am risking losing the engine any time if i don't check the dipstick every week. this is awful. isuzu should recall this model or at least do something. it is so unfair for car owners like me. | |||

| I bought a 1999 isuzu trooper in february with almost 45,000 miles. my wife and i had our babies in febrauary and this was to be her car. on july 3 the engine blew. the car at this point had 47,000 miles on it. the car had a 5 year, 60,000 mile warranty. the dealer says it will cost $7,000 to $8,000 to get a new motor. i have since done some research and found that quite a few trooper's have had this problem, whereby the engine either loses all of it's oil very quickly or uses it at a rate it should not. *jb | |||

| I have a 1999 isuzu trooper that has a chronic oil consumption problem. i had the dealer replace piston rings at 22,000 miles but it did not significantly reduce the problem. no, i am noticing a number of trooper owns with the same problem or even with engines that have seized from a direct result of the problem. i spoke to the local isuzu service rep in new jersey and he finally owned up to the fact that my particular year has a know engine defect that will cause it to burn oil. i burn it at a rate of approximately 700 miles to a quart of oil. the rep has told me that they could replace the engine but with the replacement there is no guarantee i would get better than 1000 miles per quart of oil. *la | |||

| I have a 99 isuzu trooper s, and have owned it less than one year. i bought it with about 51.500 miles. it now has 8000 miles on. i live in a small town and i use this vehicle for minimal purposes. getting mail, groceries, etc. small errands of the sort. i was on the way over to my in-laws and noticed a ticking sound and then the oil light flashed. they live about three blocks away. my father-in-law checked the oil and then added four quarts before it even registered. neither myself nor my husband have ever noticed an oil stain or any evidence of oil loss. after he added the oil, the knocking subsided and it seemed fine the next couple of days as i used it around town. then on my way out of town, in about 20 mi, i heard a knocking sound, but the temperature was fine and there were no warning lights on. i decided to stop anyway and to call a tow truck in fear of any further damage that driving may cause. the service station that looked at it has informed me that the engine is shot. the isuzu company has a powertrain limited warranty for a period of 60 mo/60000, whichever is earlier. i have been told by my local isuzu dealership that the in-service date is 03-03-99, and that it is out of warranty. although it is still under the 60kmi and only four months over the 60 months, they will do nothing to help. i also contacted the isuzu owner relations department and received the same response. in my further investigations, i have found numorous complaints of the same type of problems . it seems to be that this mysteriously missing oil problem occurs in the 98 and 99 models. i'm currently at a stand still on what path to take. my vehicle is at the local service garage, unfixed . i have contacted the better business bureau with a complaint. i am waiting to hear back from them. meanwhile, could you please investigate this problem. thank you.*ak | |||

| 1999 isuzu trooper.. oil consumption leading to severe motor damage. ( over a quart per 1,000 miles) have heard of several of the same incidents with others driving isuzu products having the same outcome as i. a complete motor overhaul with 64,000 miles on this trooper. other instances with fewer miles. isuzu is aware of the problem, only manufactured this particular model for two years. isuzu was notified and then in return let my mechanic knew where to begin repairs and to what extent they would be. i live in a very rual community in maine and i know of at least three other instances with the same outcome. more importantly isuzu does not stand behind their vehicles even when they know there are problems. *jb | |||

| I purchased my trooper new. i have all of the print outs of the oil changes made which are at or below recommended intervals. at approximately. 25000 miles i reported a shifting problem and they replaced the transfer case because metal filings were found in it. then 2000 miles later the problem re-occurred and they replaced the entire transmission. it was bought in back 500 miles later for and adjustment on this again. at 40000 miles the cd player jammed and they replaced this with a new one that took 8 weeks to receive. we had followed the directions in the manual. following this, the cd player again jammed @ 51,000 miles and they refused to repair it -out of warranty- at this point we realized that part of the directions in the manual were faulty. we did report this to the dealership to no avail. it is still not fixed because they will not release the code to repair it. each of the times that we have had this in while still under warranty, we have had to complain to receive a rental/loaner car while it was in for several days at a time. then at 60000, there is an evap. code that indicates there is an issue with the vent valve and it is not performing correctly, but the dealership has told me 3 different times that it has been in 3 different causes. now at 74,000 miles , i have just been informed that the short block has to be replaced and the heads may be cracked. the last oil change was at 71,800 miles and the oil light did not come on. they claim that there was no oil in the engine but, the oil dipstick says that there is a proper amount. this is a 7400+ repair. this is the 12 the time this vehicle has been in to the dealership. all repairs have been done by an authorized dealer. *nlm | |||

| My 1999 trooper threw a rod in the engine. it is not drivable. i have had the trooper in the shop 3 times before with other problems, before the warranty was up. the dealer did not want to discuss the problem. in trying to find another engine i was told that this was a common problem and that it was very hard to find an engine. no new ones were made, nor was a repair kit.*jb | |||

| Sometime in february of this year, the engine failed on our 1999 isuzu trooper, possibly due to low oil. no warning lights or symptoms of any kind - vehicle just quit on route 95 in mansfield while my husband was driving home from bowling. car was towed to local garage, where they confirmed that engine needed to be replaced - in fact, the tow truck driver had literally picked pieces up from the pavement underneath the vehicle. upon searching for a new engine, we discovered that they were not easy to find unless purchased directly from isuzu, and according to consumer affairs website, this is primarily because this type of failure is common among isuzus manufactured in late 1990's/early 2000's. our regular mechanic, and several others questioned, confirmed that the isuzu's were notorious for this type of problem. bottom line, it would cost us $5000-$6000 dollars to replace the engine, which is about what we owed on the car. *nm | |||

| 1999 isuzu trooper purchased new. began experiencing excessive oil consumption between oil changes around 50k miles. regularly took a qt of oil every 1k miles. oil and filter changed every 3k. dealer service manager said this was normal oil use for this engine. at 128k engine fails 4 hrs from home (sept 2003). nearest dealer is called and says it has thrown a piston due to lack of oil. we pay to have the vehicle towed back to our local dealership service department. engine is replaced at our cost. we have engine dismantled by ase certified mechanic and the failure was a spun rod bearing. no evidence of lack of oil. this is a terrible engine and would recommend anyone driving an isuzu with this engine get rid of it asap.*ak | |||

| I have a 1999 isuzu trooper that i purchased on 7/27/02 with 67,000 miles on the odometer. it now has 72,800 miles. it is a v6 with automatic transmission, and is in excellent shape. during my ownership, at four separate occasions, as i was coming to a stop at about the 5 mph mark, the throttle has opened fully while in gear! i have had to panic brake the vehicle and push the transmission selector to neutral. when i have done this, the engine has raced to 6000 rpm+ and held, so i have had to turn-off the ignition switch each time. after gathering my nerves, i have restarted the engine. the first three occurrences happened in traffic, so the problem has been a real safety concern. last night, this problem happened in my own driveway. i nearly took-out my garage. after keying-off the ignition, i restarted the engine. the engine raced a second time while the transmission was in neutral, so i shut it off again. i then turned it on again and the engine went to idle. this problem is pretty hairy, and on monday i intend to call the local isuzu dealer (billings, montana). but, i really think this complaint needs to be brought to the isuzu technical people. thanks for your time. | |||

| This car has been a nightmare. basically an accident waiting to happen. the manufacturer and dealership have given us the run around on the vehicle. it stalls when the vehicle comes to a slow. occurs at major intersections when turning or waiting to turn. has been serviced 8-9 times for same problem. 3rd time this past month. car breaks down on way back from dealership! getting no help from isuzu incorporated. *ak | |||

| The vehicle misses out and then dies while driving. it may miss out days before dies or the same day or not at all. speed, weather, and how long it has been running have not been an issue. it has even died when i had been dirving for 2 hours and was going 70 on the highway. it has been in 5 times and they say they can't find any thing wronge but it keeps doing it. the driver seat slips forward even though the track has been replaced twice. before the track was replaced the last time the seat was fixed you could just set in it and lean forward and it would tilt and slid. it has been in 4 times for this among other things.*ak | |||

| The vehicle has stalled while in motion on several occasions. there has been no warning prior to any of these failures. in each case, the vehicle was able to be restarted immediately after the failure. this has been occuring intermittently for about 6 months and the servicing dealer (hall isuzu in newport news, va) has been unable to determine a cause. although the servicing dealer doesn't appear concerned, i feel very strongly that this vehicle is unsafe and that eventually this defect will cause the vehicle to be involved in an accident. while i am not a mechanic, the sudden nature of the failures seem to indicate a problem with the electrical system.*ak | |||

| My trooper first entered the shop on december 13, 1999, and was in for the same problem on two other occasions. the car has run hot three different times, and has the engine has run many miles with a mixture of oil and water in the engines internal components. i am very concerned about an engine failure at highway driving speeds, and also about future engine life. the manufacturer has been little help. my car is out of the shop now but was in for many weeks. 8ak | |||

| Dt: the contact owns 1999 isuzu trooper. on 8-04 she took vehicle for 60,000 mile maintenance and vehicle blew up in 7-05. she said the cause was a pcv valve that did not work and allowed the oil to drain into another part of the engine. she had to have the engine rebuilt, and the mechanic that did the work told her this. she felt there was a defect in the pcv valve. the warranty stated that the dealer covered the parts from the original manufacturer, labor performed in conjunction with the repair for 12 months or 12,000 miles, and vehicle was included under both protections. they will not cover the cost. the dealer laughed at the contact and told her the trooper was known for engine failure.*ak *nm | |||
