 In 2002 i purchased a impala ls with 3.8 engine. cass # chv0350387 ---08/15/03---as stated prior--consumer wants the manufacturer to repair the vehicle correctly. i feel that the repair that is been done on the vehicle is not correct and in a matter of time the problem will recur again. referring to the above stated paragraph the problem has occurred with the vehicle with less than 60k. the vehicle is loosing antifreeze at a consistent rate and is needing repairs immediately. if repairs are not done then the vehicle will become a driving hazard to both passenger and fellow users of the highway. the recall was a defect management repair and wasn't completed in a quality and professional manner. this vehicle needs immediately attention to resolve the injury liability of all concerned. it was and is still the responsibility of gm to make this right. it should not fall to the customer to make the costly needed repairs now. when it was assembled and sold to the customer. this matter should definitely be researched to confirm the problems which could be somewhat different but originated from the same recall. *tr

 It started back in 2002 a few months i purchased my 2002 impala. it was a used car with 15,000 miles. the check engine and low coolant light came on. took it to the dealership and had the water pump and low coolant sensor replaced. a week later, low coolant light comes on again. again took it to dealership and had to replace another sensor. that happen 10 times during the same year. as of now, july 2009, the light is still on. in 2007, my vehicle started to run hot. was told i needed the manifold intake gasket, thermostat and hoses replaced which would of cost me over $1000.00. i couldn't afford it. i got a local mechanic to replace everything which he charged me $300.00. just recently, i've been having problems starting my car especially after i drive it for a while. i'm a single mother who goes to school and work and this is my only means of transportation. this car has been giving me the blues the past few years and i'm sick of it. all this started with about 150,000 miles and currently i have about 168,000 miles. i will get a better, dependable vehicle later this year and i won't buy another gm vehicle again. *tr

 We are the owners of a 2002 chevrolet impala ls. we purchased the car new in october of 2001. it has been lightly driven and well maintained. it has had two major repairs; the first being a recall of the steering system, the second, a failure of the catalytic converter which was covered under federal law and replaced. today, i found out that there is a safety recall for possible fire from dripping oil. that is the basic history. for about a year and a half, we have had a frightening issue with the car. you turn the key and nothing. a light that says security flashes three times over and over and you cannot start the car for ten minutes. gm's passlock system, which i believe malfunctions, thinks the car is being stolen. ten minutes later, you can start the car. the problem is even in the manual for the car. gm admits that, but they say it shouldn't happen as much as i have it happen, like one time is ok, but the 5-6 times out of 10 that my car won't start is exceptional. ten minutes is a long time with a sick child, alone in a dark place at night, in an emergency of any kind. it is a terrifying safety issue and i have read thousands of complaints all over the internet. gm offered me a coupon towards a new car. i know this is a known problem because it is in the manual and people are frightened and scared about it. this should have been a recall a long time ago since people are being stranded with a car with no fuel supply. due to the car's computer somehow malfunctioning and thinking the car is being stolen, the passlock system reacts by cutting off fuel supply for a designated period of time, in this case, 10 minutes exactly. gm should be ashamed of themselves for having this issue and doing nothing. *tr

 2002 chevy impala 3.8l purchased used in dec. 2004 w/ 65,000 miles. where to begin... flooding in floorboards due to clog underneath windshield, three sets of rotors/brakes, clunky noise in steering shaft (replaced twice by dealership) still having same problem, catalytic converter replaced after dealership tried to charge me nearly $1000 to replace; covered by gm as harry green chevrolet was 'unaware' of replacement policy?!? new struts, numerous alignments/balances b/c vehicle still shakes and shimmys at 60-65 mph; must drive about 75-80 mph just to keep this to a minimum! bcm replaced twice by dealer, security issues won't allow car to start for 15 mins. each time, which is very inconvenient. sooo many problems and complaints with these 'quality' gm vehicles, and yet they do nothing to resolve them, except hold out their hands wanting more $$$ from american taxpayers to keep on making junk! and now the newest of a long line of recalls/problems is that there is a fire hazard for leaking oil on the manifold! all of these vehicles need to be recalled due to the numerous safety concerns and consumers are sick and tired of general motors obvious disregard for safety and reliability! *tr

 I have a 2002 chevy impala with 80,000 that i bought brand new in 2001. approximately 3 months ago i had to have my vehicle towed to a repair shop as the antifreeze leaked out into my driveway. i was told that the manifold gaskets had failed and needed to be replaced. also they found that the front brakes were bad and the rotors needed to be replaced. with regard to the leak i was told i was lucky because most times the failed gaskets causes the antifreeze to leak into the motor and seize it. i had the repairs done at a cost of approximately $1,500.00. this past weekend while on the beltway my car started making a loud knocking noise and before i could pull over the motor died. i had the vehicle towed and was told the engine was blown, that they know of at least one piston was in my oil pan. now i need to have the motor replaced. which i have gotten prices from $4,500 - $6,500.00. also, they told me my brakes are bad again, only after 4 months. *tr

 Owner of 2002 chevy impala that has an intake manifold leak. family member also had an impala, 2003, and had the same issue. why is this such a problem? when i searched the issue online i found many owners that had the same issue. gm needs to issue a recall on this problem and have proper gaskets installed in their cars. this car is not a cheap car, and to have these problems is a sign of a poor quality. *tr

 Had intake gasket replaced in feb. of 2006 for coolant leaking into engine oil, because of said gasket failing (77,000 approx. mi.) noticed coolant level dropping again in jan. 2007 (85,000 mi.) found white/brown sludge in oil again!apparently the problem is back and i am told it will keep coming back until gm corp. comes up with a permanent fix. why are they not concerned about this? i can't afford to keep on fixing this problem that has no end in sight. i like my car but if gm won't address obvious design flaws i'll have to buy from somebody else. *jb

 At 89,000 miles i noticed that my engine coolant light was on. i filled the coolant. the light continued to come on and i filled it a few more times, but could not pinpoint the leak. then one night the engine started to make noises and i pulled off the road to check the coolant. i filled it and waited until the car cooled. i started the engine and drove about a quarter mile and the car shut down. when i towed it to a garage i learned that the head gaskets were leaking water into the engine. the engine had to be replaced. since the warranty expired i paid the garage to put in a used motor. it cost me over $1300. i never thought to contact chevy since the warranty expired. now, because of my internet research, i know this is a common problem. unfortunately for me i also bought a second chevy in 2002. wouldn't you know it - my 2002 chevy malibu had the same symptoms at 62,000 miles. i was lucky enough to get by with replacing the head gasket. the same garage gave me a price break and fixed it for $252.00. boo to chevy. *nm

 My 2002 impala has just 70k miles. the low coolant light came on and over heated several times. the mechanic says that it is a intake gasket that needs to be replaced and that this problem is not unusual with the dextron coolant that gm uses. i have heard of this problem from many mechanics and it seems that gm is aware of the problem and needs to fix this very expensive repair. my failure happened when my family was stranded on the side of the road because of no coolant in the engine. *jb

 At approximately 50,000 miles i had been told that my car had a minor antifreeze leak at the lower intake. now at 130,000 miles it has turned into a major problem that will require at least 600 dollars in repair costs. i have been told that alot of impalas do this. have not resolved the issue yet, nor received a recall notice.

 Two months after i bought the car both my headlights fogged over. they cost $250 a piece to replace (have not yet replaced). about a month later a computer chip that controlled my lights, locks, windows, interior lights, and stereo went bad and that cost $353 to replace. soon after that i noticed that my car felt like it moved back and forth when i drove it, and the steering wheel was very loose when i turned. i didn't think it was a very big deal but took it into the shop to have it looked at. i took it in and found out that i was missing 2 bearings on my suspension which put pressure on my drive shaft(not sure about actual terminology here not sure if it was drive shaft or steering column) causing my rack and pinion to go bad. that cost $1100 to fix. so now i am $1453 into having my car repaired for things that should never have gone bad in the first place. today (may 9th 2005) i found out that my intake manifold has gone bad and i can smell burning antifreeze when i drive, and my coolant sensor is bad. to fix those two things is going to cost me $840. i should also mention that i have checked this car out on carfax.com there was only one previous owner and nothing signifigant as how it was treated. i purchased this car at 34,000 miles and it now has 53,000 miles. this car has been nothing but problems since i bought almost 2yrs ago. i have called gm customer service 3 times now, and each time i am given the same answer i am sorry ms.... there is nothing we can do for you at this time.... gm needs to get their act together and start making cars that are worth what they sell them for. had i known how gm made vehicles with bad parts and refuse to back them up, i would never have bought the vehicle that now sits in my garage.

 I wanted him to check my driver side back door because it wouldn't open very easily at times, and the window to that same door would not open at times. also, my trunk wouldn't open when one would use the trunk release button at times. i also had him check my dimming headlights, my steering which had a jerk in it when i went around curves, clicking sound in engine and an over all check since my warranty is about to run out in 1,000 miles. turn out-after leaving the dealer my air conditioner was humming like a helicopter, my brakes were horrible and grinding and the car feels like it has no get up and go power. i took my car to brake check after leaving because when the dealer did the overall check of my car they said i needed a front brake job. and they wanted to charge me over 200.00 dollars. the dealer told me it was not covered under my warranty. well brake check took off all four tires and found that my problem was due to left and right caliper problems on the inboard side and left rear hard wear problems and wear on the outboard side. the caliper is engaging but not disengaging and caused my pads to wear out and my rotors are ate up. the pads are not worn evenly which is definitely a sign of caliper problems. also, the dealer upon the overall inspection of my car said that my intake gaskets were ruined and leaking coolant. they said they replaced them, however i am afraid that there is further damage to my vehicle that they are not telling me, just like my brakes. due to the fact that steve at lone star told me that it was caused due to lack of oils changes and gil said it was a problem with the gaskets being improperly seated from the factory or just a defect in the gasket. well is this why my car has no get up anymore? my car also made a grinding sound when hitting bumps under the right front fender area that nothing was done about and my headlight problem they said was due to a faulty battery cable. *nlm

 The vehicle's gas tank would not fill because air had gotten in the tank. the dealer has been notified. *nlm one must hold the gas nozzle away from the filler tube and restrict the flow. the tire and fuel system/tank/injectors were replaced. there was a rattle sound coming from the engine due to the injectors the vehicle would stall. after the engine is hot, the next time the vehicle would turn over but no start and run rough. the fuel gauge fluctuated(not giving actual amount). the solenoid was replaced due to hanging by the hose retainer. scc

 I purchased the vehicle used from another dealer in 2003. i started experiencing problems with the security system in november 2005, it would not start sometimes light would flash and after 20 minutes it starts. the problem went away until last november, and then it would do it about 2-3x a week. in february 2009 i had to replace my lower intake manifold gasket, water pump and battery. the summer 09 i had to replace the radiator due to a hairline crack in it. the security system starts to intermittently not start the vehicle again in late sep. 09 about 2-3x per week. in jan.2010 the vehicle doesn't start for me one day after coming out of the grocery store for 25 minutes. since then it does it every morning when i go to take my child to school and i have to wait 10-20 minutes. i took the vehicle to the gm dealer and was told they weren't familiar with this problem and i needed $950 for parts and labor to replace the ignition switch and the bcm. i had the ignition switch replaced by another mechanic and that was not the problem and the vehicle is still doing the same thing. it's frustrating for me and my child. it's scary and dangerous. i'm so afraid that one day or night it may not start and i'm stranded in the streets and may be subjected to a crime or death. i don't drive it at night unless it's an extreme emergency now and this is such an inconvenience. i have to pay for rides at times to get my child to and from school when this car decides not to start so my child won't be late for school or getting picked up from school. i've also had to replace my windshield wiper motor and my driver's side door window regulator. *tr

 2002 chevy impala - did fine the first year or so. engine light started coming on. long story short - been having to make sure there's always antifreeze for years now and hoping and praying i don't end up on the side of the road. now i'm noticing having to add 1/2 to 3/4 gallon of antifreeze everyday. temp light goes off and on. engine light went off which worries me more than when it's on. now noticing antifreeze burning after i have drove it a little while. leaves me a little puddle now each night. seems to lose antifreeze more in the winter while running the heater than it does in the summer. tired of stressing about the pos!!!!!!!!! *tr

 2002 chevrolet impala i have a 50 / 50 chance of getting this junk to start. i have talked to the dealer and all they want to do is replace the bcm and the ignition, but judging from the other complaints on this model why spend the money if it is not going to fix the problem. some one some where must know how to fix it, it can't be that difficult. what i have been doing to get it started is leave the key on the on position for a full ten minutes until the security light stops flashing 3 times. if you try and start it to soon you have to wait another ten minutes, the great part about all this is gm wants the government to bail them out because they are loosing money, i wish gm would help bail me out of this piece of junk, i'm losing money trying to keep this thing going. *tr

 Noticed brownish color of coolant on the 2002 chevrolet impala, some sludge built-up in radiator. this car has 59000 miles on it. dealer reported the problem to be a intake manifold gasket. cost of repairs to be $500 plus. it appeared this to be a common problem that was related to the type of coolant gm used.*ak

 At around 40,000 miles our 2002 impala had brown stuff similar to pudding in the radiator. we have learned that it was caused by the dex-cool antifreeze that general motors puts in their vehicles. at about 100,000 miles the car overheated. we took it to the dealer and they said it needed new head gaskets at a cost $1300.00 possibly higher if the heads are damaged. this is a very common problem with gm vehicles yet gm refuses to acknowledge that it a defect in their product. we have purchased a ford car and will never purchase a gm product again. i had been a gm man for 30 years but not anymore. *jb

 Purchased a 2002 chevrolet impala used at a local chevy dealer. the coolant light has been on for a month, but i could not find any leaks, the dealer tells me it is the lower intake gasket and the cost is ($1000). he also mentioned that this is a common problem in that the gasket is now plastic, whereas previously was made of metal. he also stated that the replacement part is also plastic and indicated that this will probably need to be replaced in the future. there is no better proof of planned obsolescence. as i am doing my research, i find that this problem is very common. the service manager even said they he is surprised that there has not been a recall. thx, gek. *nm

 I have a 2002 impala. i experienced a coolant leak for several months. i took it to the dealer who told me they needed to replace the intake manifold gasket. this can result, among other things, engine seizure, blowing a rod, etc. i believe this is referred to in service bulletin number: 070803 and nhtsa item number: 10003814 per records found on this site. after calling chevrolet's 800 number, i was told there was a recall associated with this for my vin, but they only offered it for 2 years, from 07/03 - 07/05. since i purchased this vehicle used, i was not sent a recall notice and now it appears i have to pay the rather expensive repair bill.

 Purchased a 2002 chevrolet impala used at a local chevy dealer, in less than 8 months i have come across two problems. one, the turn signal starts acting up and affects the system and they tell me it is the multifunction switch ($400.00) and the second, i noticed i had to constantly add coolant/water to the radiator but could not find any leaks, the dealer tells me it is the lower intake gasket and the cost is ($1000). as i am doing my research to find a more reasonable cost to which i can accommodate, i find that these problems are too common in the version of the motors/style of vehicles. so far, that even two of the shops i have taken the vehicle for an estimate have said they are surprised that there has not been a recall, especially in the lower intake problem. where can i turn to, to try to get help and make sure these manufacturers take care of these issues that are very costly and as you can see, in less than 3 to 4 years, the consumer has to pay for them. thank you!! *nm

 Engine coolant leak at the intake manifold, or at the lower intake manifold to lower intake manifold gasket. this condition may result in a low engine coolant level or coolant pooling on manifold. same problem as noted in tsb#03034(nhtsa id#10003430, july 01, 2003) this problem is present in my impala that has been well serviced every 5k miles and suddenly presented at 96k miles. *jb

 Low engine coolant light went on. had it checked out. local mechanic said that oil was getting into the radiator, possible intake manifold or head gasket problem. went to chevy dealer explained the situation and he stated it was very common problem with 2002 impala. he diagnostic the problem as the intake manifold gasket, cost to repair $1000. i phone another chevy dealer cost $800, local mechanic $600. cost of the parts at autozone less than $75 amount of labor time should be 3-5 hours. chevy dealers 8 + hours. all this because gm uses bad antifreeze. gm caused the problem they need to step up and provide assistance to impala owners. needless to say this will be my last gm product. *jb

 1. low coolant light was continually on, and it did require coolant at the time, but there was no indication what was happening to the coolant - after 2 weeks of smelling antifreeze within the vehicle, it was then discovered that the coolant was leaking around the lower intake manifold gasket near the bolts and then this led to the replacement of the gasket itself..it took 8.5 hours of labor and the cost of the new gasket to correct the problem. 2. there is a loud clunking noise in the front end of the vehicle when turning the vehicle at slow speeds...apparently it is the intermediate steering shaft and has been identified by the chevrolet dealer but will not fix the problem for us...they say that there is no recall for this problem, but admit that they have numerous complaints about this and that they have tried to get chevrolet to recall the vehicle because of the complaints from their customers. both problems that i have listed are a continual problem for many impala owners and i feel as though since they have issued numerous service bulletins to their dealers about both of my complaints, that they are aware of the problems but still refuse to correct them for the consumer. as a consumer i feel as though gm should be investigated and made to fix these problems for all of us 2002 impala owners. *nm
09/08/20051
 Around 58k miles the low coolant light came on and i was informed that there is a slight leak around the intake manifold gasket. this was a common problem due to the dex-cool antifreeze that is used. i have contacted the dealer and they won't do anything for me, and the cost would be around $700 to repair. i've been nursing this issue for several months as the leak was slight, however now it is greater and must be dealt with. i have gotten nowhere with the dealers and will have to repair it and bear the cost. *nm

 2002 chevrolet impala, coolant light has been on for 2 years. took it to a dealership when it first came on, only to be informed that it was a corrosion problem which was not covered by my bumper to bumper warantee. now i discovered that gm's choice of dex-cool antifreeze is very well known to cause corrosion problems, and there are a myriad of consumer complaints about dex-cool destroying head and intake gaskets as well! i expect gm to make good on a problem that they themselves caused, instead of their to-date snively policy of passing the buck back to the consumer. (in short, if this issue is not resolved to my satisfaction in a timely manner, i will never buy a gm product ever again!)

 I have twice had to take my 2002 chevrolet impala to the shop (resulting in lost time from work and unnecessary repair bills) because the low engine coolant warning light comes on and stays on even though the coolant level is full. the repair shop has twice found oil in the coolant, despite having flushed the cooling system and installing a new low coolant level sensor at a cost of $165. now i am told that this is a common problem with the intake manifold gasket on this type of vehicle and that it will cost around $900 to fix it properly. this car had only 20,580 miles on it when the problem was first attended to and now still has only 21,557 miles. *jb

 My 2002 chevrolet impala suffered a breakdown of the antifreeze that turned into a thick brown substance. this caused the vehicle to overheat and gm did have the coolant flushed. two weeks later the lifter began to rattle when the vehicle was first started. when i took the vehicle back to the dealer, i was told that a seal was leaking coolant into the oil. i was assurred that this was not related to the original problem and was not covered. the repairs will cost over 760.00. i called gm customer service and after waiting all day, the response was that the service manager was not there, but the problem could not have been caused by the first problem. the coolant turned into a thick brown gritty substance that would have been like sandpaper going through the engine and they claim that it could not have caused the seal to fail. it is obvious that general motors refuses to stand up for obvious failure and defective equipment. they refuse to stand up for the repairs. this coolant according to gm is supposed to last at least 100,000 miles and it does hold up as they state. they should admit the problem and make the proper repairs to customers vehicles.

 In january 2006 my 2002 impala loss power. i was going up a very small hill and i didn't think i was going to make it up. i took my car to my local mom and pop's garage and they put it on the computer. it showed that the catalytic converter was bad eventhough the check engine light did not come on. i had them replace not knowing that the car was still under warranty for emissions and they didn't use a gm part. a few months later, the check engine light did come on. again it showed the catalytic converter as the problem. the service technician said he had never had any problems with putting a non-dealer part on a car before but did replace the converter once again with a non-gm part in case the first one happened to be a bad part. a couple of months later the check engine light is back on. took it to the dealership and the catalytic converter shows as well as the transmission. of course, they wouldn't make good on the catalytic converter by this time because it was out of warranty and it wasn't the original gm part. i was told that it would cost $775 just for them to look at the transmission. i cannot afford this and just brought the car home. i'm still driving it but it's worse and worse every day. i wouldn't trust driving this car very far. i've read many complaints on the catalytic converter & the transmission that you would think gm would have to step up and do something. at this point i would never purchase another gm vehicle and my husband is diehard gm. i've taken very good care of this car hoping that it would last until my daughter starts driving and i could hand it trustingly down to her but that's not going to be the case. my husband doesn't take care of his trucks like i would and he still has a 1995 that runs good.

 I own a chevrolet, impala - 2002. in the beginning of april i was on my way to work and when i attempted to pull out into a busy four-lane highway as i hit the gas pedal to accelerate the car felt sluggish as though it were not getting enough gas or not shifting into gear. that evening i stooped to fill up the gas tank and upon leaving i was climbing a hill and the car acted up again and made a different sound and again acted as though it were not shifting into gear or not getting enough fuel and the security light (not service engine) came on and stayed on. i immediately phoned my husband and he made arrangements to take it to the dealership (john serretti). we have maintained this vehicle faithfully since we purchased it oil changes, tires rotated etc. all performed at john seretti's every 3/4 months. after reviewing all paperwork received at home for the impala my husband came across a letter from general motors mailed in october 2005 stating that some vehicles were experiencing loss of power due to the catalytic converter and if we did indeed have any issues with this to take to the dealer and they would replace it, but if not, nothing needed to be done and this letter was not a recall. the dealer performed a diagnostic test ($90) and found that indeed the catalytic converted was clogged and supposedly caused the spark plugs wire to arc and melt which all had to be replaced at our expense (almost $600). my husband has talked to several mechanics in reference to this and they all agree this could have been a potentially dangerous situation possibly causing the vehicle to catch on fire. gm did cover part of the repairs but in my opinion they should have covered them all because the converter was defective and if carbon had built up to that extent to cause all of this damage and leading me and other mechanics to believe it could very well have started a fire, why wasn't it discovered at the previous inspection-oil change? *jb

 Mis-diagnosis and willful negligence vehicle was brought in for diagnosis of engine knocking and loss of power upon acceleration at highway speeds. dealership diagnosed a clogged catalytic converter, however, the symptoms returned within 15 days. now the dealership says that the engine is damaged and must be replaced at a cost of $5,000. the vehicle was only purchased 6 weeks ago at a cost of $12,000. the first repair was made under warranty, however, now the vehicle is beyond warranty. *jb

 Dt: engine started to spit and sputter. it got worse. caller changed fuel filter because the dealer said it might be the problem. while driving the vehicle the car ran fast and tried to take off, and she had to slam the brakes hard, and hold them to t stop car. dealer said a hole was burned into the manifold, and when they did a diagnostic test, they said a misfire code came up. problem was with catalytic converter being plugged. dealer fixed the burned intake manifold before they found that the problem was catalytic converter. that was the only thing wrong with it. *ak

 The intake manifold gasket is leaking. it poses a fire hazard if the car is overheated which could pose health threats to those in the car and others outside of the car. the car is a 2002 chevy impala with 71,000 miles. this car has had regular maintenance and is good condition. there have been several things fixed over the past two years. we have spent over $3,000 fixing everything. we cannot afford to fix yet another problem. this car should not be facing these problems at such an early stage. *tr

 2002 chevrolet impala experienced a problem with stalling and misfiring.***no answer required***. *mr this was an intermittent problem. a hole burnt through the upper intake manifold, resulting in excessive amounts of air to enter the system. the clogged converter was the source of the problem which allowed excessive back pressure to build up in the system and gases that were much hotter than normal entered the manifold. *sc
