The contact owns a 1996 Pontiac Bonneville. The contact stated that several attempts had to be made before succeeding in starting vehicle. The vehicle was taken to a mechanic where the failure was located at the intake manifold and oxygen sensor. The intake manifold cap was melting and causing oil to spill. In addition, the failure was producing white smoke from the tailpipe exhaust. The vehicle was repaired but the contact was unsure as to the exact repairs made to the vehicle. The contact also stated that the anti-theft system failed and would alert the contact that the doors were opened, and the seat belts were not secured erroneously. The fuel injection system was also defective and was repaired by replacing the fuel injector, and adding fuel cleaner. The contact referenced NHTSA campaign id numbers: 96V116000 (fuel system, gasoline: Fuel injection system) and 95V204000 (electrical system: Ignition: Anti-theft controller) however, the contact was advised that the vehicle was not included in either recall campaign. The current mileage was 158,000. The approximate failure mileage was 140,000.

This car belongs to my elderly mother which she bought used and has been an on going problem! occasionally when starting the car, the engine will backfire, after starting it would run ok. The car now does not run as the intake manifold is broken from the backfiring and almost caught on fire the last time it was attempted to start the motor! according to Pontiac there is no recall on this car by the VIN number!!
