Needless to say, as along with everyone else, my coolant started to leak from my 2002 Chevy Impala. I noticed the low coolant light would come on, then go off, at first. Then, sitting in traffic one day, my car started to overheat. I made it home, and noticed a nice stream of coolant spilling onto the drive way. Went to the dealer, and of course, my warranty was up. I was told I needed a manifold, oil change, (since the coolant was getting into the oil), and thermostat. I have no problem with the dealer, as he said it's such a common problem, he has cars coming in every week with the same problem. He also said that Chevy isn't giving any money to the dealers to help finance the repairs. Which I believe fully. Malibus also have this problem too, I was told. So my problem is with Chevy. They are unbelievable. To have so many cars, with the same problems, and not issue a recall for it. What kind of company does that to their customers? OH, A ONE THATS SINKING! It's not fair to stick ordinary people with a huge repair bill that should be covered by a recall. If anyone has any information on where to sign up for the class action, PLEASE LET ME KNOW.

my impala is a 2002 3.4v6. My problems started about 70000 miles low coolant ligth, steering column bushings, drivers side front wheel bearing, drivers side tierod end and gas mileage dropping off badly. We took car on trip and the gas milage sucked. I took it to a GM dealer and found that the converter was bad. I couldnot believe it, luckly it was covered under warranty. The dealership replaced coolant sensor said it was bad but it was not too long after being replaced it came back on. I starting noticing a coolant smell but could not find the leak. I finally had my wife take it in to dealer to find the problem. I got a call shortly saying that the intake was leaking 650.00 dollars to fix it. I ask the service manager if this was a common problem. Well you already know the answer. I want to get in the lawsuit, anybody with info?

This is so horrible, I thought I just had a leak with my coolant, I have been replacing the coolant almost everyday of the week filling it back up. I finally took it to Midas to get it checked out and they told me that they always get people with this problem with impala's and that it will cost me $604.28 to have it fixed, and it needs to be done immediately. I dont have that kind of money laying around. This is my only form of transporation. I want to be on the list, they need to recall this piece of crap.There's a class action law suit pending get on the list

I am a college student with not a lot of money. This problem has caused a huge set back for me. I rely on my car to get me to and from school, my job, and even to hang out with my girlfriend. I started noticing a problem when the coolant overflow tank started having a nasty brownish splatter on the inside of it. I called my buddy up who is a certified mechanic and studying to be a shop teacher. He said that the 3.4 liter motors are notorious for having the intake manifold gaskets fail. I asked him what it would cost to get this repaired, and he told me between $600-$800. With my lack of income at this point in my life this repair is very hard for me to swallow for some dumb ass engineer's F'up at GM. I hope this lawsuit goes through and GM is forced to fix their mistake via repayment for the work, or a recall on cars that haven't had blown the intake gasket yet. We'll see how things go.

This problem of the leaky intake manifold gasket first started with the low coolant alarm coming on intermittently when the car was still under warranty. I had the coolant low level sensor changed under warranty. When the low coolant level alarm came on again I disconnected the sensor thinking it was just a nuisance. The next thing I noticed was that the coolant had to be topped up regularly.

Last year I was informed by the GM dealer that my intake gasket needs to be replaced at the cost of about $1000. Of course the warranty was up at this time.

Since then I have been keeping my eye on the coolant level and topping it up regularly. I had assumed that the coolant was leaking to the outside as I can smell coolant and the block appears to wet under the intake manifold.

Last week my wife complained that the engine was making a lot of noise when she started it in the morning. When I heard it over her cell phone it sounded like the lifters weren't getting any oil. After I got home I checked the oil and noticed it to be off colour a sort of brownish tint. I had the oil changed and now the engine sounds great starting up in the cold. Now I'm thinking that the coolant is getting in to the oil and possibly doing engine damage. I guess I'll have to bite the bullet and get this gasket changed or trade in the Impala for a Toyota.

I have always been A GM man but after this problem with the Impala and a premature failure of the transmission in my Astro van I doubt that I will ever buy another GM in my lifetime. What really annoys me is that GM has to know that they have used defective gaskets on the Impala but won't extend the warranty to fix the problem.

The low coolant light came on while driving through the city last year. I checked it and it was low. I noticed the sides of the overflow tank were pretty "dirty" so I decided to change the coolant once the weather got warmer. (DEX-COOL SUCKS) I changed the coolant in June and noticed that it seemed to drop a little bit but I figured it wasn't full the first time. Until the end of November, I didn't have to add any coolant. About that time, I started to notice a coolant smell, but I couldn't find any leak. One day I got out the flashlight and started looking. I noticed a small puddle under the "intake manifold". I contacted my mechanic and asked them to check it out when I brought it in for inspection. Before I took it to him, I changed the oil. I always take a good look because you can tell alot from it. It was discolored (brownish instead of black). I asked a mechanic about it and he said there was coolant in it. I called the dealer and he said bring it in. I just got off the phone and he said the intake manifold was leaking. I told them there was a TSB out about the problem. He said it wasn't covered under warranty. I said that proved there was a problem. I don't know if that is causing my cost to be lower. I asked about the damage to the bearings and he said he had no way of telling. He said they would add a can of additive and hope for the best. It's not making any noise-YET!!! I pray I found it early enough. I think GM ought to pay for this. I've never had a problem with an intake manifold gasket leaking unless it wasn't properly installed. I've "loved" this car up till now. I hope GM steps up and takes responsibility. I have been a loyal GM owner until now and hope to continue. Add me to the class action.

I am sick of expensive repairs. This car has 110,000 miles on it but this problem should not happen at any mileage. A couple months ago I had to put on a new header pipe because the flange broke off at the engine -> $550!, I also had the wipers get screwed up and stop up on the windshield instead of where the ae supposed to stop. I fixed myself but it would have been a $200+ repair. It tuns out that these are both very common Impala problems! Now, I need the intake fix for about $1000! I cannot afford this car! GM should have recalled these and fixed all fo them! This problem should definitely be a class action lawsuit! Sign me up!

I am a big 'Buy American' person and really give friends and relatives a hard time when they buy their Toyotas, Nissans, etc...! I am not ready to give up on all American cars but I am certainly fed up with this one.

Since August my low coolant light has come on periodically. When I check the radiator and the overflow tank they are full. I was told it may only take a drop or two of coolant for the sensor to think it is full. I had my car at the dealer for an oil change and mentioned the problem to them and asked that they check the problem. I was called later in the day and told that I have a "slow" leak at the intake gasket, the thermostat is bad and the sensor needs to be replaced. All this for the unbelievably low price of $1,000 and that doesn't include the cost for the diagnostics. I didn't know what to do. I called my brother-in-law who does all of his own car repairs. Then I decided to check out the internet and low an behold when I typed in my problem at Google it took me to this website. I think my dealer and I will have a long talk tomorrow. Oh and did I mention that they called me back before the end of the day to tell me they would pay for 50% of the repair costs...........
