Tl* the contact owns a 1996 pontiac bonneville. The contact stated that several attempts had to be made before succeeding in starting vehicle.

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!!
No incidents but there is damage done to the fuel , emission and brake line the fuel and emission lines from the fuel tank use a plastic quick connect coupling just underneath near the rear passenger side tire . The coupling becomes lose and sprays the fuel lines and brake hoses with fuel this washes off the protective layer of the hoses which then corrode and leak fuel and brake fluid , this happened on my 1996 bonneville can anyone email me if there are any recalls on this car for that reason or if I am entitled to repairs by the manufacturer.
I put gas into my 1996 pontiac bonneville went to start it and it backfired and started running ragged and check engine light came on.
When I purchased my 1996 pontiac bonneville sse used I searched for any recalls on it I found 2 one for the intake breaking and one for the anti theft system I took it to local dealer they said it was not applicable to my vehicle now I have had issues with backfiring constantly and have even called pontiac help line where I was informed that my VIN number was not valid and there were no recalls on my vehicle fast forward a few months and my wife this morning went to the store where the car backfired and the intake exploded into several pieces and large amounts of smoke issued from under the hood now this will undoubtedly cost me a small fortune to repair what am I to do now?
Tl*the contact owns a 1996 pontiac bonneville. When the contact started the vehicle, the engine backfired severely. He opened the hood and noticed that the engine plastic cover was shattered. He removed the cover and found that the upper intake manifold failed. The manifold was replaced, but the failure recurred when the vehicle was started. The contact discovered the federal safety agency campaign id number 96v116000 (fuel system, gasoline:fuel injection system) pertaining to the same failure. He notified the dealer, but they could not locate the recall. The dealer referred him to the manufacturer, but they could not find any failures because the vehicle was older than ten years. The vehicle is currently at the dealer. The current and failure mileages were 93,495. Updated 1/26/09 *cn updated 01/26/09.
Around jan 2008 while driving a plastic water hose burst. I replaced it and had no other problem until around aug 2008. This time the water pump started leaking. I replaced that and the thermostat and radiator cap, but I still kept loosing coolant. Then I found a crack in the radiator which I replace around the end of aug 2008. I still kept having to top off the coolant reservoir ever two days. About june 2008 I started having trouble with the veh starting, it would seem like it wasn't getting enough gas or flooding. It would be running but barley and it would not accelerate when you press the gas pedal. Finally it would start. It doesn't do it all the time but it's doing it more often now. I've fuel system and injection cleaners with no change. Then I went to the federal safety agency and found a recall 96v‑116 that seems to be the cause of my problem. I went to the local pontiac dealers and they said that my VIN was not part of the recall and that there was nothing they do. I told them that I would bring back to get a diagnostic test.
Dt*: the contact stated a leak in the brake line was discovered and resulted in the vehicle being taken to an independent mechanic. After further inspection it was determined the brake and fuel lines were rusted and required replacement. *nm updated 02/21/06.
Recall on fuel injection-intake manifold pontiac could not tell me if and when this repair was ever done as their system doesn't go back that far- I had this repair done last year and told them that there is no way that 2 manifolds would be defective in one car- they said there was nothing they could do as we bought this car used- all I wanted to know if this recall was used on my car when and were the repairs were done- they couldn't tell me this info-- can you get this info ?? Thanks.
