Please briefly describe your complaint: I have a 2003 Chevy Malibu that has been leaking coolant since the day I have bought it. I have taken it numerous maniacs and they have all told me the same thing that my intake manifold gaskets were leaking coolant and that this isn't the first time they have seen this problem. These mechanics told me that the gaskets for this car and the manifold itself were not engineered correctly and that's the reason it is leaking coolant. I was also told GM did however fix this problem by designing new gaskets which they are using to replace the old ones when these people bring there car in for this problem. Okay one problem right there where was the recall on that? that a health and safety hazard right there because or gms engineering. Im not sure if your aware of this but the smell and fumes from this leaking into the engine are disgusting. Also I have done online research about this problem all you need to type in is problems with Chevy Malibu intake manifold gasket thousand and thousands of complaints whit people all over America have this same exact issue and its not that they pay the $900 to get it fixed the first time then again about a year to a year in a half later they also pay this price again because the same thing has happened I am one angry american and I there are thousands of more I will not give up on my case for as well as my fell americas in this country who are experiencing this issue. Please help us!! this is not far this should be a recall on GM and I will do what ever it take to get to that point.
