 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

 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 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
