Vehicle would stall when either turning corner or taking foot off accelerator pedal. Took to dealer several times, and mechanic could not find anything wrong. Had alternator replaced. But, problem still exists.
1999 Pontiac Bonneville electrical complaints
Page 2 of 2: complaints 11 to 22 of 22, newest first, as owners wrote them.
Dashboard has signal to show that windshield fluid checked, but there is no a signal to show that doors are open. Book where it shows a door checked is page 2-76 in pontiac book, and consumer is concerned about safety matter.*ak the vehicle does not have a door ajar signal on the dashboard. The consumer believes the lack of this signal was a safety problem.
Horn never works properly.
Car stalls while driving. No power brakes, no power steering. Car stalled at 3,889 mile, 4,372, 6,108, 8,9127, 11,023, 11,772. Clairmont has repaired the a number of times.
While driving at 50 engine completely shut off, leaving only dash board lights. Consumer took vehicle to dealer, and they said that mechanism in the brain shuts off car if going 95 MPH. Second time, dealer could not duplicate problem. Put a monitor on car which still did not duplicate the problem, on june 3, 2000, dealer found that crank sensor wa s defective, and that it would kill engine. They replaced it. Consumer had the same problem on 11 of nov 2000, same problem occurred again.
The horn doesn't work when pressed as described in owner's manual. You must hit a certain spot on the wheel to honk horn. Dealer says he cannot do anything about it (3 times) because it's how the vehicle is made. Happens on all 1999 bonnevilles I tried.
When thoroughly warmed up, from a stop, usually making a turn, the car does not accelerate normally. Hesitates and acts just as though starving from fuel. Happens a third of the time. Anti-knock sensor is retarding engine timing to a negative reading when it should be a positive 20 degrees during acceleration. Dealer has replaced two sensors and the same situation still exists. Dangerous when merging with or crossing traffic.
Positive post broke off of battery leaving acid inside engine compartment.
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.
Rf door would not open due to fender interfering with door jamb. At the same time, the engine tended to stall and sputter. Car stalled on railroad tracks and passenger was unable to open door. Car was restarted and no accident occured, however, this couls have been a serious problem. Generator was replaced, but hesitation in engine performance persists. Dealer has had car 44 days during past three months. Sun roof replaced. Door / fender problems repaired twoce. Fenders removed so that insulation (sound, heat) could be properly installed. Headliner in interior was incorrect size and was replaced. Dealer states it cannot ascertain problem with engine but acknowledges problem.
I believe the horn "button" on these cars is a safety hazard. The manual states that you can press anywhere on the steering wheel pad to blow the horn. This is not true. It can only be blown at the two top corners of the pad, and it takes an excessive amount of force to sound. For some reason, the left side is harder than the right side. I checked this on another car (of the same make and model) on the dealer's lot, and it was the same. In an emergency requiring the horn to be sounded, it more than likely would never be sounded; especially by a woman or older, weaker person. Some sort of revision is needed here.
Engine stalled without warning while coasting or starting off from stop - 3 times. Dealer had a computer program upgrade which he installed after the first two failures. Vehicle is currently at dealer - who, as of this afternoon, has not been able to reproduce the failure.
