Also have collant leak (started last year and then seemed to go away - but is back), have replaced the window switch on driver door, blinkers work when THEY want to - not when I need them too, and have had the car fail to start several times for no apparent reason. I'll try again to start in about a half hour or so and it will then start!!! Driving us crazy. We loved this car and the way it road but are now getting nickle and dimed to death.

Intake manifold replaced 2times,1st time about 58,000 and then again at 101,000 miles. !st fix obviously not good enough. 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$$. The engine started running rough, and it seemed to mimic transmission problems (wouldn't shift properly and wouldn't go over 50mph)... found out the plenum had a few holes in it. Replaced plenum but it burnt right through again!!! What do I need to do? Any suggestions??? We are not sure where to go from here. Autozone said they will not cover another plenum.... ??????

Since December of last year my car has been leaking coolant. Every morning I wake up to find a new puddle of coolant on the street. I took it to pepboys and they told me it would take over $1000 to fix. I want anyone who drives a car the uses the DexCool coolant to know that there is a lawsuit against Dex Cool. To get added to the lawsuit go to www.dexcoolsettlement.com. must file claim by October 27, 2008. If you want to sue GM on your own you must exclude yourself by August 13, 2008. for complete information and a Claim Form or for updates to this Notice: Call: 1-866-245-4291.

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?

Impala 3.4L V6

  • Automatic transmission

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!!!!

Impala Sedan 3.4L V6

  • Automatic transmission
  • 86,000 miles

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.

A D V E R T I S E M E N T S

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.

Impala 3.4L

  • Automatic transmission
  • 52,000 miles

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.

Impala 3.4L

  • Automatic transmission

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?

I GUESS YOU CAN ADD ONE MORE TO THE LIST SAME EXACT PROBLEM HAVE TO HAVE TH INTAKE MANIFOLD REPLACED. THAT CAR IS A PIECE OF S**t, AND WHEN WE GET THIS REPLACED I WANT TO GET RID OF IT, 1,000 REPAIR AND WE HAVEN'T FINISH PAYING FOR IT YET, CHEVY SHOULD BE ASHAMED OF THEMSELVES, THAT'S TRULY ONE WAY TO LOOSE CUSTOMERS. 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!

Impala

  • Automatic transmission
  • 97,000 miles

Well, I can see that I'm having the same problems with my 2002 Impala as everyone else here. Low coolant light on, leaking antifreeze, was told that the DexCool (which is recommended for use in this car!) reacts with the gasket and eats is away, causing the leak. There should definitely be a recall or class action suit for this. Why should all of us consumers have to pay out the "you know what" for repair charges on this?? Needless to say, I am VERY upset. Right now, my car is at the dealership with an "estimated" repair bill of $1,000. I have had problems with this Impala since the day I bought it -- brand new! The brakes are terrible, have had them fixed so many times, turn signals stop working and/or only work when they want to, a/c hoses/vents problems, all of this is just ridiculous. It's really a shame because the Impala is a nice, roomy vehicle. But definitely not worth all this crap. If there is a recall on this cooland leak problem, would love to know -- and add me to the class action!
