Problem Reports

 Rookie

car was leaking coolant, had to have intake gasket replaced. Leaked coolant again, had to have freezeplug replaced. continued to leak, was told the head gasket was blown. been driving it for about 2 years on blown head gasket.

I have had to replace my intake manifold gasket three times now, three years now. This car has been nothing but trouble since I got it.

I went in for an oil change and was asked if I smelled the sweet smell of antifreeze when I start the car, I replied no then was told that the gasket was leaking and it is a common problem on the vehicle. I asked if that would have been corrected when the fixed the head gasket and he was surprised that that had to be done already due to the low mileage. I was told it would cost about $800 to correct the problem and have not had the work done since I don not smell anything unusual when I start the car.

Coolant leak to the oil I have to replace all the gastkets

0verheats, leaks antifreeze, cost $860 to repair

Coolant in oil. Coolant always low after adding every few days. Noticed oil turning brown. Has to be the intake gasket leaking.
Just had the timing chain cover gasket changed two weeks ago. What a money Pit!

replaced that gasket 3 times and it still leaks! I was told if you dont also replace the bolts it will continue to leak, did that and it still leaks!

changed gasket but it started again by 140000 miles.

I had the Low Coolant light come on. Took it into the dealer who said I need new Header Gaskets. I am assuming I need Lower Intake Manifold gaskets as well.

I've been reading that is a common problem with GM V6 engines as the DexCool coolant degrades the plastic gaskets.

This is apparently a known GM problem. There was a class action lawsuit that was settled in 2008 on this issue. However, GM should do a recall on this issue as it is huge. I will never buy another GM car or American car for that matter.
