1996 Pontiac Bonneville recalls (2)
Fuel system, gasoline › Fuel injection system
A backfire during engine starting can cause breakage of the upper intake manifold.
Remedy: Dealers will update the powertrain control module programming. Until the campaign repair is made, the vehicle hood should be shut whenever starting the vehicle to reduce the chance of personal injury.
Electrical system › Ignition › Anti-theft › Control module
These vehicles were assembled with a malfunction alarm, lighting and locking (mall) module that can contain a damaged capacitor. If the capacitor is damaged, the "key in the ignition" warning chime and the driver seat belt unbuckled warning chime and indicator lamp May not work. This does not meet the requirements of FMVSS no.
Remedy: Dealers will inspect and, if required, replace the mall module.

Tl* 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. …
On 02/18/2002, 04:20 am, my wife went to start the car to let it warm up before going to work. Upon start up, there was an explosion and there was a fire instantly. I ran out and rolled the car out of the carport and into the back yard. The neighbor came running with a fire extingusher and put out the fire just before the fire department arrived. There was a recall (your number 96V116000). The upper intake manafold did fracture from one end to the other...gapping open about two and a half inches.. My car was repaired for this recall on 01/19/1998. I guess that this was not a fix for the problem. The GM investigater looked at the car and told me "that there was nothing that we had done to cause this problem". He would not say anymore. On 02/18/2002, the prrson for GM called and said that they would not accept any liability for the problem. …
Air bags all 27 →
Tl* the contact owns a 1996 Pontiac Bonneville. While driving 35 MPH, the driver and passenger side air bags deployed inadvertently without warning. The vehicle was not involved in a crash. Due to the failure, the windshield shattered. A police report was not filed and no injuries were reported. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure. The vehicle was not repaired. The failure mileage was 151,474.
I left my house on 9/10/2011 and went to gas station. After fueling up I noticed that my airbag light was on. I did not pull over because I thought it was just a sensor problem and I had never heard of anyone having to pull over for the airbag light. I proceeded to the highway and when I reached 57 MPH I put on my cruise control. In about 2 minutes both of my airbags deployed and my visibility was 0%. If I had not had both of my front windows down, the powder that engulfed my car could have suffocated me. I am on breathing medicine for copd. Although my car is up there in years it is not up there in mileage. I purchased the car from someone 4 years ago, who only used the car on special occasions. When I purchased the car it had 58,000 miles on it and only has 91,500 today. This whole process took about 15 minutes from start to finish.
