Consumer bought the Bonneville in August, since then it has been in repair shop 7 times. The first four times were for transmission failure. They replaced the pressure control valve and throttle body. The remaining visits were for 4 fuel injection system failures, injector coil failures melted 4 spark plug wires. Also, water pump started leaking.

1998 pontaic Bonneville SE, standard V6 engine, while stopped with the brake engaged the engine will surge and leap forward. Car engine will quit while driving, causing loss of anti-lock brakes. Transmission sometimes shifts up and down without any reason, even at speed causing control problems. Suposedly related to the design of the intake manifold ( plastic cracks causing vacum problems and sometines loss of water). Also exterior paint started to peal off at 70.000 miles.

Transmission bucks when in acceleration on a hill---bucking is severe--call to your attention because others in area have exactly same problem---I fear transmission will become noticeably worse as problem continues.

When the vehicle is stopped on a slight uphill incline it will roll backwards when the brake pedal is released, and before the throttle is depressed. This was reported to the servicing dealer (jackson Pontiac, macon, ga.) I was told that this was normal for this or similar vehicles. I have never owned a vehicle with an automatic transmission that would not hold itself in this or similar situations. I believe that this is a safety defect and should be remedied by the manufacturer. The potential for an accident is great. I have documentation of their report if you need it. Thank you.
