What owners wrote

Chevrolet impala ls with 3.8l engine. The upper manifold warps and allows coolant to leak. This is a very common problem. My car is in the shop with no parts available in houston. There were 15 on backorder. GM needs to replace this plastic part that warps at 17-24,000 miles.

The intake manifold/gasket on this vehicle has to be replaced. Car was overheating when idle. No heat was being generated. Cost to repair has been quoted as $580. This is a known problem on these vehicles, GM needs to issue a recall as any knowledgeable mechanic is aware of this very common problem, due to poor-quality intake manifold/gaskets being used on these vehicles.
