Impala LS 3.8L

  • Automatic transmission
  • 60,000 miles

I bought my 2002 Chevy impala ls in 2006 with 30,000 miles. For the first year the car drove fine with no problems. But out of nowhere it started to fall apart piece by piece. First it was the radiator, than it was the intake manifold gasket which for about two years now ive had replaced twice. Its really unfortunate because the car i originally bought for about $13,000 and i still have to pay a car note on it every month and am investing more and more money on repairs than the car is actually worth. I would like to know what i can do about sueing or anything that can help because up to this date i still have this issue after having it repaired several times by several different mechanics. never again will i buy a Chevy or gm car. they are real pieces of crap!

I will NEVER get another chevy impala. it has the engine comartment fires in the engine, and all kinds of stuff wrong with it. it seems like everything goes out on it. its also got a few more recalls on it. its horrible. i replaced my intake gaskets and it had a cracked intake manifold plenum, my eentire brake system and my alternator, all the power windows. Its in the shop now for the intake manifold, oxegen sensor, and its using too much fuel. (running rich)) Over all, i dislike this car very much. everything seems to just be wrong with it. one thing after another

Impala 3.4L

  • Automatic transmission
  • 162,520 miles

First of all, back in 2002 when I first bought the car, it had 15,000 miles on it and the low coolant light was coming on. Brought it back to dealership many times to get the sensor replaced. Less than 6 months after i brought the vehicle, i had to get the water pump changed. Low coolant light was still on from then all the way until now. I got the radiator changed twice, thermostat changed twice and water pump changed again. Car started to run hot every time I drive it. Found out I needed the manifold intake gasket replaced. Since my extended warranty was exhausted, I had to end up paying for it out of pocket. The local mechanic shop wanted to charge $1000 to get it replaced. I couldn't afford it because I had gotten laid off from my job 3 months prior and I had to get this replaced so I can look for another job. I told my mom's boyfriend about it and told me his cousin does work like that. I took a chance and drove it to his cousin's home while the car was still running hot. He got it fixed, charged me $300.00 to get it done. I thank God for him fixing my car. Now it seems the transmission is failing. When I drive it, it changes gear hard and when I stop and start it again, it's hard to start. As soon as I start another job, I will save up to get me another vehicle, It won't be a GM this time.

Well I replaced my whole Engine because of the the lower intake was leaking coolant, and it was mostly my fault for not taking it in to see why my check engine lights was on; however my engine light had been on for a few months because of the catalytic converter, and i was told that i had a ways to go before i would have to replace it. And over 1yr. from my engine going, my converter still is working fine. I ended up spending all the money i made bartending that weekend on replacing my engine. I ended up getting a used engine with 50,000 miles on it. It has about 90,000 now a year later nad now im back to why i had to replace it in the first way. the sh*t that upsets me is its expensive to fix, and and the engine that i blew had about 150,000 miles on it.So now i can't drive which means i have to pay for other means of transportation when if it were affordable to fix i could just relplace the intake gasket. It's an American Car so it should be inexpensive to repair. I'm feeling like i should have bought a honda, i hear they last longer. If GM wasn't so f*cking greedy, they would have not gone under. See what happens when you rip off you customers. Assholes.

I originally purchase my Chev Impala in 2002 from a dealership. I paid extra for the extended warranty and have religiously taken my vehicle back for every service check. Which is approx. every 3000 miles. At no time did anyone mention anything about this lower intake value problem. The warranty ran out ran out during the summer of 2006 (60,000 miles). I did not find out about the problem with the lower intake manifold until now. All the service checks since 2002 have indicated no problems with the coolant system.

What I particularly find annoying is the fact the GM knew about this problem but never advised the owners.

I am considering purchasing a new vehicle this year but it won't be a GM product.

Too bad GM will not own up to a manufacturing defect. The more research I do the more problems I find with Dexcool damaging the gaskets. I actually had my cooling system flushed and refilled at 42K to be proactive with my maintenance. Two months later problem with the intake gasket failing. Why does GM not make a recall here, since they already know about this from thousands of complaints and have a TSB evidencing problem.

I had my Intake Manifold Gasket replaced in June of 2008 because of a leak, and the coolant light coming on and not getting much heat, and have the same problem again. I can't afford to get this fixed again so at this point I am just dealing with it. Wow, this is ridiculous if there are this many complaints on this web site about the same problem then I can't imagine the number of complaints as a whole that are not on this site. Why is there not a recall for this? Unfortunately I own 3 other Chevrolet's but like others on this site, once I sell these I will never buy another Chevrolet again. I have had nothing but problems with these cars as a whole.

OMG! I can't believe GM is not stepping up to the plate! I've sworn for years that GM made the best autos and were always known for having Good Motors(GM). Every used vehicle I've owned were made by GM/Chevy and this has been the worse ever. Thank God my boyfriend knows how to do this painful job. It's been costly and very stressful, let alone time consuming! I called 3 local Chevy dealers and 1 Pontiac dealer and they were all familiar with the problem, which bothers me. They should warn people about this when purchasing the vehicle.

I have 3 car notes left to obtain a free and clear title and needless to say this is my 2nd coolant leak on my engine also. This time it's that LIM gasket and we just replaced the water pump last week. To top it off, my low-coolant light and check engine light have been coming on intermittently for about a year and I was always smelling coolant but never saw any coolant on the ground. I don't know how many bottles of Dex-Cool I purchased over the last year. If anyone knows of a class action lawsuit against Dex-Cool or GM please add me to the list. I won't buy another GM after this one!!!

I purchased my Impala in August of 2002 by 2006 I had replaced the "BRAIN" because it would suddenly fail to start for no apparent reason. I took it to the dealership, who had me replace the starter, ignition switch and a few other parts that didn't fix the issue. Finally the dealership said well...maybe you should replace the "BRAIN" but it'll cost you $1,200. Well gees what about the other $1000 or so dollar that I had already replaced.

In the summer of 2006, I noticed there would be a weird smell coming from my car after being driven. There was NEVER any fluid on the ground or garage concrete; apparently it was leaking onto something and it would heat up and smell like it was burning. I took it to the dealership again and they informed me that I had a LEAKING INTAKE VALVE and would cost over $1200 with at least 9 working hours. I am really agitated with CHEVY and what is worse is that they could careless about my dissatisfaction with their vehicle. I now understand why CHEVY is in the shape it is. POOR QUALITY cars. I will never again buy another Chevy.

I had just bought this car, and the low coolant light flashed. I thought it was nothing but a sensor glitch. About a month later I noticed a little puddle of coolant under my car. I had replaced my thermostat and seal. I thought this would have fixed it. To no avail. I just went out side to see where it was leaking from and it's right where the manifold meets the head. I am glad that I caught this leak before major engine failure. I looked around to see how much this would cost if a dealership were to fix it. They quoted around 900 to 1000. I decided to fix it myself. Good thing I have my 84 Fiero to back me up.

In December of 2006 I bought a 2002 Chevy Impala from DriveTime.The the problems with the radiator started about Oct 2007. I thought I found peices of "stopleak" in the radiator. It turned out to be gasket material. The motor blew up while my girl friend was driving back to work in May of 2008. I had the car towed back to DriveTime, who are now ready to garnish my wages for $8000.00 USD. Someone please HELP! Where do I find the list for the Class Action Law suit pending?

I wish I had of heard of this site before purchasing this car 2 months ago.
The first two weeks I had no problems at all until the coolant light kept reappearing.
Now I have to put coolant in the rad every week and don't have time to get it fixed.
You can see clearly that the intake manifold is the problem#$%#^@% this lemon car.
I had bought this car to replace my 1990 Dynasty when I should have just kept the old one.

Impala 3.4L

  • Automatic transmission
  • 102,000 miles

My son's car, 2002 Impala, 3.4L started linking antifreeze. Never really saw a leak in the garage but noticed that the coolant light kept coming on. Would ck and the level would be down. After a few months I thought I would tear it apart and start working on repairing it. Everything I read and hear indicated that the lower intake manifold was linking. I decided to do it myself with a friends help. I bought a lower intake manifold gasket set at Autozone for $89.00. We took off the fuel injectors and got down to the lower intake manifold. Chevy made this engine so you don't want to work on it. It seems that you have to take off all of the wiring since it is clipped to the engine in all of the wrong places. Had to remove accellerator cables, alternator, belt, power steering pump, coolant overflow just to remove a bolt from the alternator. After taking out and putting back the rocker arms and push rods, noticed that one of the rocker arms was loose because of a collapse lifter due to water leaking into the motor oil. Tomorrow will be putting in a new lifter to replace the one that is collapsed. Hopefully this will take care of the situation. After talking to a chevy mechanic, he told me I didn't have to remove the rocker arms & rods even though that is part of the chevy instructions manual. Looks like another way Chevy makes money on labor since they go by the computed hrs for repairs instead of quoting the actural short cut hours. That's probably a hour labor charge you pay that they never do. If you have time and patience, you can do this on your own since there wasn't any special tools you had to have. Hope Chevy can resolve this issue since so many people are having it.

We have had all the same problems; coolant/blinkers/electrical(lights).

ATTENTION GM this car is a piece of @#%# are you going to wait for someone to possibly die while they are trying to get their lights to work in the dark before you take notice. My Daddy raised me a Chevy girl and I used to be proud to be one. NO MORE!!! I've went foreign and am raising my girls not to buy GM. SOOO< if your wondering why your sales are down DUH-UNSATISFIED CUSTOMERS WILL DO IT EVERY TIME and I urge everyone on this website to let all your friends, family and co-workers and even strangers in the grocery stores NOT TO BUY GM and lets raise a new generation of kids that knows what a ripoff GM autos are, and how they don't stand behind their inferior products.

Love the way the car drives but sick of the cooling problems. !st Chevy or gm purchase and definitely the last. at 103,000 miles had to have head gasket repaired, coolant leaking into the engine, 1500.00 repair cost, now i cant believe it but the catalytic converter is bad, thank goodness that is covered for up to 120,000 miles, boy is Chevy gonna here from me.I bought this car brand new and always maintained it properly. cant afford it any more. my 99 ford Taurus that i bought used is 100% more dependable. very disappointed in Chevrolet.

This car has been a pain in the a$$.

To get added to the lawsuit go to www.dexcoolsettlement.com. must file claim by October 27, 2008.

I love my car, but the cooling system really sucks!! I have replaced 2 cooling fans, and a radiator. It still gets hot, has a slow leak and GOD knows where, and the freakin low coolant level light made itself into a decor for my car!! I've heard of the intake manifold issue, but it hasn't hit there yet. No one seems to know where this slow leak is coming from. Where ever I go, there will be a trail of coolant!! It is a really nice car, but this issue needs to be addressed. I have read so many complaints of basically the same thing!!! And with the gas prices being so high, it's hard to keep taking it back to the shop for the same problem, but a new diagnosis that never seems to get fixed right!!!! So where do we go from here?

Yet another victim of the 2002 Impala!!! We have had endless problems with the cooling system, which has led to many more problems. Intake manifold gasket, cooling fan motor coming apart, Cat converter, "low coolant" light comes on whenever it feels like it, "change engine oil" never turns off, not to mention the 3 DIFFERENT WINDOW REGULATORS!!!!!!!! I've gotten so good at replacing that stupid part, I would replace the 4th if the PART hadn't jumped to $120.00+ EACH (IF YOU CAN EVEN FIND THE REAR REGULATORS IN AN AUTO PART STORE) Well I'm sure I'll Have To SOON!
And how about those brakes. We have gone through 2 sets of rotors in the past 3 years.
Please let me know if there is a class action suit to get involved in. We need to hold them responsible for there inferior production!!!!

The 3.4L V6 2002 Impala is a piece of ****! I have added enough coolant to the reservoir
to create my own environmental hazard. I never smell it, see it on the ground, or on the motor, but it definitely disappears somewhere!!! And that ******** "low engine coolant" message will show up, despite the gauge showing that the temperature is A-OK. I am told that, eventually, that message will communicate with the computer...and will stop me dead in my tracks. I see from the posts on this site that the intake gasket is more than likely the problem. Well, that puts me in mind of another GM product, the Olds Delta 88. It had a plastic plenum and a tiny hole would appear, allowing coolant to get into the engine, "faking" a blown head gasket. It faked it so well that I spent over $300 and hours of shade tree mechanizing to replace the head gasket, only to find out from the dealer that it was the plenum. Parts guy failed to tell me it was a "common" problem.
And, GM wonders why their sales in the US are so dismal !!!

We checked the internet and saw that there were many people with this same problem. Contacting the Chevy dealer with this information did NOTHING! The dealer wanted between $1,000 and $1,500 to fix. We fixed it ourselves. Chevy needs to reimburse everyone for this. Get me on board for the lawsuit.

I bought my Impala and it had a slight intake gasket leak, i bought an engine with 40000 miles on it for 800 and had it replaced for another 800, now with the newer engine in it, the intake gasket has started to leak again. The problem is that GM recommends the Dex cool coolant but didn't make their gaskets able to stand up to this coolant. The dex cool breaks down the gaskets causing a leak. So far i have replaced both hub bearing, the catalytic converter, the engine, and an o2 sensor. I had to do all of this except the hub bearings just so i could renew my registration in IL because you have to pass an inspection first before you can be legal to drive. Overall cost to keep my 2002 impala on the road....2500....If there is a class action lawsuit i would love to be added to it.

YES, it's the coolant leak from the intake manifold gasket. So far I have put in stop leak and tightened down the manifold bolts. It seems to have slowed down the leak but not stopped completely. I have replaced two cats, one coolant sensor so far. Now I am having the powertrain module locking up and not permitting a engine start. I have to remove power to it for a reset and it will then start. I now also have the check engine light on. (haven't checked the code yet). I am a Chevy man but getting upset with some of these inferior design problems.

I bought this car from an individual , it had 15,349 miles and was in excellent shape. My low coolant light came on and would stay on, then it started to leak in the driveway. I took it to a dealer and the mechanic knew what it was when I said low coolant light on. This is a very common problem with this engine. Was there a recall on this?

About a year ago my low coolant light came on. I checked the levels and they were fine. Added some water and it has not done it again....just today (Feb 20, 08) my car smells like burning coolant. Now I'm worried.

I GUESS YOU CAN ADD ONE MORE TO THE LIST SAME EXACT PROBLEM HAVE TO HAVE TH INTAKE MANIFOLD REPLACED.

I WAS TOLD THAT IF IT WASN'T A SAFETY ISSUE THEY PRETTY MUCH DON'T GIVE A DAMN ( IN OTHER WORDS THE CANT BE SUED FOR SOMEONE DEATH AND THAT'S ALL THAT MATTER TO THEM. I WILL NEVER BUY ANOTHER CHEVY VEHICLE

Same problem as all the rest. Leaking coolant and low coolant light. Refill coolant but light stays on. I agree that with a know part weakness like this should be a recall item. Bummed out to say the least!
