Selected complaints filed with NHTSA by 1995 Pontiac Bonneville owners, lightly cleaned up (personal details are redacted by NHTSA).
The wiring harness caught fire. The fire was due to a faulty wire harness behind the steering wheel from the light control switch. The entire switch was melted, especially the wire harness plug hat connected to the wiring harness directly to the switch.
Tail lights, backup lights, fog lights, and dash lights did not work. The fault wa s the lighting control module which had a recall issued. Pontiac was not willing to repair the vehicle under the recall 94V190000 concerning headlight failure. These vehicles were assembled with lighting control modules which can experience excessive current leakage due to damaged surface mounting capacitors. This can cause loss of head lamps and parking lamps. Consequence: sudden loss of headlamps can cause reduced driver visibility which can result in a vehicle accident. Also, the head lamps cannot be turned off, or they May turn on while the vehicle is parked, resulting in loss of battery charge and inability to restart the car. Remedy: dealers will replace the headlamp module. Notes: system: lighting; head lights. Vehicle description: passenger vehicles equipped with twilight sentinel lights. …

Airbag deployed while driving. Light came on and about 30 seconds later passenger bag went off and blew out the windshield. The insurance company fixed the window but are claiming that this is a mechanical defect and is not covered unless a rider is present on the policy. I feel this is a disclosure violation as I would have had that rider in tact. This vehicle still needs airbags and systems repaired. The driver side has been disconnected to allow for the vehicle to be driven as the insurance company has halted the rental car and are dragging there feet getting an agent to the house to look at the vehicle.
We have replaced one lighting switch. The wire harness was melted. We asked about a recall on this 2 years ago when it happened. When it goes out we have no tail lights and no dash board lights. By the looks of other complaints we are not alone. With this many complaints about an electrical wiring default where is melts down like ours did or the cause of a fire why is there not a recall on such a dangerous thing. Would they rather be sued and be liable for deaths if a person is caught in their vehicle when it catches on fire. This is definitely an item that needs to be on the recall list.

Front and rear windows joint welds break leak into the vehicle starts and the airbag module shorts out and can blow anytime this has not been recalled or looked into after I sent in compliant now some kid riding in rain had his blow out and caused an accident with injuries and they wanted to buy back the car for $600 ???? Are they crazy my white paint also peeled but they wont fix it. So I have a shorted out module leak in my front and rear windows and a two colored car they should go bankrupt.
All of the dashboard panel lights were inoperable in the vehicle. The dealer examined the vehicle and replaced the head light switch and the connectors. The manufacturer is aware of the problem.
The vehicle experienced the same problem as stated in recall #95 v 204 000, however the vehicle identification number was not included in the recall, and consequently the vehicle caught on fire.
