“I have a 97 Pontiac Sunfire. It has a faulty fuel injector which leaks all over my engine. The fumes blow into my vents and is hard to bear. I also have three small children and don't want them even in the car but it is all I have to drive. I called dealers and they said it has nothing to do with safety or any recall, but the car is only six years old and in great mechanical shape. It has been taken care of so I do not see why the fuel injector should be faulty already. I feel as though GM wont help me at all. This is apart that should not be bad so soon. Thanks.”
