The contact owns a 2003 Chevrolet Impala. The contact stated the vehicle would intermittently overheat and leak antifreeze. When the failure would occur, the contact would move the vehicle off the roadway and shut off the engine until it cooled down. The vehicle was taken to a local repair shop where she was informed the intake and manifold gaskets would need to be replaced. The manufacturer advised there were no recalls for her specific vehicle and would not provide any assistance. The failure and current mileages were 157,000.

I recently found that the intake manifold gasket fails on the Chevrolet 3.8 V6 and that Chevrolet has known of the problem for years and has not corrected the problem. I travel cross country regularly in my 2003 Impala with the 3.8 engine and am concerned that the engine will fail on the highway and could cause serious accident. Before I knew that GM was aware of this problem I owned a 2000 S-10 pick up and had the gasket replaced for over $700 dollars. I now face the same expense or more to fix the Impala. I feel that GM should have recalled and fixed his problem because hey were aware of the defect in the gasket and plastic coolant part going through the valve cover.
