CTV reports that some General Motors vehicles may have a serious defect which could lead to total engine failure.

The issue is the intake manifold gasket in some GM vehicles. According to CTV, the part may degrade in vehicles built between 1995 and 2003. In worst-case scenarios, the gasket is failing, introducing coolant to engine oil, rendering the latter ineffective and resulting in siezed engines. Affected vehicles include the Chevrolet Monte Carlo, Pontiac Grand Prix and Aztek, and several Oldsmobiles. Service bulletins obtained by the news source indicate the automaker has been aware of the problem for years.  However, GM currently does not have a recall on these vehicles, since degradation can have a variety of causes.

An online petition asking GM to issue a voluntary recall has collected some 11,000 signatures.

A full-listing of affected vehicles can be found at the link.

GM has since come out with a new, redesigned intake manifold gasket for its newest vehicles.

(Thanks to everyone for the tips!)

      I have a 1982 Chev Caprice and so far have not had any problems with gaskets. My problems have been the headliner and a door handle but neithor left me stranded. I think I will stick with GM.

      I bought a 1998 Chevrolet Silverodo. Right from the start the windshield wiper system stopped working, and
      that happened durring a heavy rain storm. Fortunately
      we didn't have a accident. Shortly after that the intake maniflod developed a leak and a loss of fluids
      began. I expected a recall to take place on both problems but none has taken place so far. I,like so many others will never buy another GM vehical because of the high prices GM is asking for junk they sell.

      That sucks. This happened to a couple of people I know. One was a 93 Buick Regal with the 3.8 and a 93 Park Avenue with a 3.8. It may be a totally different thing but I am worried about my car now (94 Buick Regal with a 3.8. I may just take it to the nearest garage and have them take a look at it. I would rather pay a hundred bucks or whatever for a gasket than pay a few thousand for a new car.

      Happened to my 2000 Olds Silhouette @ about 72k-literally a couple weeks before the extended warranty expired. Inake manifold allowed air into GM's oh-so-wonderful coolant, which apparently turns into a thick sludge when air hits it, leading to soaring temps. Even with warranty it ended up costing I believe around $500 out of pocket anyway.

      Rastus: Everyone who buys GM is not 'white trash'. People have the right to choose designs that appeal to them over reliability with plain design. It doesn't suddenly make them below you. Quit trying to compensate for whatever male components you may be lacking.

      BTW, I have no idea what the heck a 'looser' is. Go back to grade school: its 'loser'.

      Pathetic.

      Kevin,
      Actually, IMO, the GM's I own are pretty appealing to me. I have a 2000 Pontiac Bonneville SSEi w/Supercharger, and a 2000 OLds Silhouette Premiere. They both are some of the most interesting, appealing designs in their class and I like them. Also, IMO the new Camry just looks silly with the puffy front end, the 07 Tundra looks like its trying to hard, and I'm not gonna say a word about the Yaris. Honda's offering in the minivan and mid-large sedan segment are even more boring, I think (especially at time of purchase). While their designs are cohesive and well executed, I just don't see any inspiration or imagination.

      On the other hand, look at the 3 new Saturns, the SSR, Vette, GTO, Solstice, GMT900's, etc, and they have a lot more character. The GM vehicles you mentioned are rather boring, but even still I like them better than the Honda & Toyota equivelents. I do have to say I agree with you that Infiniti, Bimmer, and Audi have much more interesting designs, but they are alos more expensive and I felt the GMs suited my needs just fine.

      But its all in the eye of the beholder.

      All I can say is that it's about time. It's a shame they let it go on for 8 years. How many people have had to pay to have it fixed?

      I have a 2006 GMC Sierra PK. under 65,000 miles , & the gasket is out of it !!!!!!!!!!!! Is any one else running into this problem , ??????

      #21 - sorry, but have you looked at GMs vehicle line up lately? Their designs are as plain as Toyotas. Look at the Malibu, Impala, etc...They all look boring and dated. At least Toyota is making an effort to have more bold designs (i.e. 2007 Camry). GM produces old looking, plain ugly designs one after another. Applealing designs are BMW, Infiniti, Mazda, Audi...Please don't say GMs designs are applealing because they are as pain as boring as Toyota's. At least Toyota has reliabilty going for them. What does GM have? NOTHING

      My 1997 Chev Lumina was leaking coolant and i had to get it replaced. My mechanic made me aware of the faulty intake manifold gasket and I feel disgusted at GM which knew of this problem would not make a voluntary recall. this car has a 3.1 litre displacement with under 80000 miles on it and had the intake manifold gasket replaced which costs about $800 I am now in the market for a new car and from what I can see regarding "customer service" with GM, I will be purchasing an import car for the first time.
      I am still hoping that GM will do the right thing and do a recall on this intake manifold gasket but I am not holding my breath.

      I've read all the comments, but I'm more concerned about if anyone has threatened to sue or recieved a refund/compensation from customer service.

      If so, how?

      I have a 95 Monte Carlo Z34 3.4L with an intake gasket filling with oil. 104k Miles. $600 to repair

      L OWN A 2001 MONTE CARLO AND I ALSO LAST WEEK HAD TO REPLACE MY INTAKE GASKETS. ALSO CONVERTER THAT WAS UNDER SPECIAL MOTICE. I BELIEVE GM SHOULD HONOR THE DEFECTED GASKETS WITH A RECALL AND REIMBURSE ANY ONE WHO HAS TO PAY OUT OF POCKET TO GET A REFUND.I HAVE 85.OOO MILES ONLY ON MINE WITH AN EXTENDED WARRANTY BUT MY YEARS RAN OUT BEFORE THE MILEAGE WHAT CROCK.
