Selected complaints filed with NHTSA by 2003 Chevrolet Monte Carlo owners, lightly cleaned up (personal details are redacted by NHTSA).
I keep rewriting this because for some reason it keeps timing out everytime I look for the video to attach. I brought the car to taska twice for underhood fire and ignition. No head gasket got fixed no spark plugs there is several issues water keeps getting in tires are rotted electrical problems and now head gasket is messed up because the hood wasn't put on till afterwards for the recall the ignition is still not fixed. Last time I drove it back it stalled out and smelled over heated
The service manager told me the Engine cover will be removed and NOT replaced. This downgrades the vehicle as the engine cover is part of the appearance element and gives a certain amount of protection to some components and wiring harnesses. It will soon be a Classic and the engine cover is part of the original equiptment that needs to be on it. There is NO logical reason the valve cover gasket cannot be replaced AND keep the engine cover in place. Thank you for your help.
