1999 Pontiac Bonneville Owner Comments

problem #18

Bonneville 6-cyl

  • Automatic transmission

A hole developed in the plastic upper intake manifold where coolant runs next to the egr valve, resulting in the car suddenly stalling and not able to be restarted, because of the coolant being introduced into the air fuel mixture. It is my understanding that this is an ongoing problem that Pontiac is aware of.

Engine will stall intermittently while driving at various speeds, resulting in a loss of power brakes and power steering. Dealership has examined vehicle several times, and has been unable to effectively remedy the problem. The consumer stated that the vehicle stalls 33 times and power failure happen when steering becomes difficult.

The car started stalling and I replaced the plugs, ignition coils (3ea), fuel pressure regulator, took to dealer and their is a seal in the intake that have had problems and it leaked water into the cylinders a little at a time and then let go. They knew they had problems with it, they said so. Est cost $1000, then they will see if the engine is still good. So it could need a new engine.

Engine stalls for no apparent reason. It happens under just about any circumstance. The most dangerous time of failure is when turning or pulling out of driveway across traffic because of loss of power steering.

Vehcile just stalled for no reason. Dealer replaced alternator twice to believe it would solve the problem. The problem wasn't solved. The 2nd time alternator was replaced because they felt it might have been a defect of alternators. Dealer really doesn't have a remedy for the problem.
