Tl*the contact owns a 1996 pontiac bonneville. The vehicle backfired when the ignition was started, and the check engine indicator light illuminated. The intake manifold was damaged. This failure occurred twice before and the manifold was replaced. A local mechanic stated that this vehicle was included in recall # 96v116000. However, the manufacturer stated that the vehicle was excluded from the recall. The contact possessed the repair invoices. The current and failure mileages were 150,000.

My 1996 bonneville started acting up, roughly idling, and hesitating when taking off. There was loss of power, poor gas mileage, car would shut it self off while driving down the highway.check engine light came on and started flashing. Took it to auto zone to get it checked. Scanner idicated that it had multiple misfires, and that my map sensor was bad. Replaced map sensor. Still didnt change on how the vehicle operated. Replaced one of coil packs, still nothing. Put new plug wires and nothing cahned. New oxygen sensor installed, and still nothing. Changes. Over all I just got done spending $150.00 on this car and I cant even afford that, and still have not resolved the problem. I replaced basically everything that the computer came up with. What can I do here to solve this problem without me hurting my financial status, and me blowing the car up.

I bought my 1996 bonneville new in that year. Around 20,000 miles the transmission failed and was replaced by the dealer under warranty. At 145,000 miles I noticed the transmission slipping and a smell of burnt fluid. Took the car into the dealer. They flushed and replaced the trans fluid stating the fluid was burnt (meaning not useful any more). I had the fluid changed a couple of times during the life of the car as I also insure all maintenance is done. That flushing lasted about 1,000 miles before the trans began slipping again and this time the check engine light came on. The result was my 3rd transmission at a cost to me of $2,500. I realize I have a lot of miles on the car/engine/trans but with proper maintenance, as I've done, I would expect a longer life from the transmission!

Car was at aproximately 87000. Turned the car on, there was a loud explosion and smoke came out from under the hood, didnt see any flames, popped open the hood, and smoke just continued to pile out. Engine light came on, and the mechanic found the engine was on its last breath. Had engine relaced for a used engine with 4500 miles on it for $1500. Soon after the engine the alternator started to die, where just by standing next to the car you can hear metal to metal grinding noise coming from it. Paid $100 to get new alternator. Right after alternator the eg r valve died, had it replaced, another $300 spent. Now come spedometer saying 99000 but the second engine only having 60000 the serpentine belt cracked and worn out beyong believe. Another $75 spend. While having that replaced the mechanic pointed out puddles of oil on the engine, thus the manifolds/gasket on engine#2 will soon need to have work done.should I contact the local dealer about the gaskets leaking...does it relate to the recall that was made on the manifolds.

While driving, engine light illuminated. Checked under hood, and realized there was no coolant in tank. Took vehicle to dealership, mechanic had to replace the plenum. Also, would have to replace it again at 90000 miles.*ak

Transmission failed completely while driving. Car made loud whining/grinding noises, jerked and was difficult to control. Other cars swerved to avoid hitting me. Once stopped and in park I tried to proceed. The dash showed the car in gear, the engine would rev but car would not engage any drive or reverse gears. Had car brought home and towed to dealer the next day. It has twice previously gone into neutral briefly while driving but there was never a "check engine" light.

The engine light came on the dash. I took the car for a diagnostic computer check which showed it was a transmission problem. I took it to multistate transmission - 3850 hemphill st. - fort worth, tx 76110 phone #(817)921-6155. They did a computer check on it which showed it was slipping at about 35/40 MPH. They took off the pan, saw sludge looking stuff in it and burned transmission fluid. They had to go into the transmission to find the problem. They had to rebuild the torque converter, replace a large number of parts, including a sprag kit, chain rocker joint, band reverse maji, sprocket stuff, etc.
