Vehicle has performed perfectly since purchase. My wife experienced hesitation upon entering a busy intersection and almost caused an accident. Upon inspection, the intake manifold (plastic) is warped causing a large gap at the interface to the throttle body allowing antifreeze to enter the engine and also causing an intake air leak which is degrading the air/fuel ratio.

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 had to have the intake plenum replaced on my 99 pontiac bonneville...started with vehicle hesitating on take off, RPM's accelerating very high but MPH not catching up...vehicle then backfired and loss all power...had it towed to dealer...dealer said intake plenum was warped causing coolant to possibly leak into engine...gm would not cover under warranty which cost me $1000 to correct...vehicle was fine for a month or so and started doing it again. I think its ridiculous that gm knows about this problem but refuses to take responsibilty for it as a factory problem..I would like a recall on this and my money reimbursed to me. I also think this problem should be repaired correctly with a part that won't burn up because its made of plastic. I have read on many websites complaints about this same problem but the problem is that they are complaining to the wrong people. I was recently informed that gm does not decide to put out the recall, it's really the federal safety agency that is responsible for that. My plan is to post this link on those websites and hopefully enough people will post a complaint here too and maybe we could get some reimbursement for the poorly built cars that all other consumers have purchased.

I have had my 2000 bonneville in the shop several times for various reasons. My radio had to be replaced, my drivers side window stopped working and they replaced the motor, now my passenger side window does not work and needs to be repaired. My trunk leaked and was told the extended warrenty did not cover it and the expense was on me. My air conditioner would blow cold air and then hot air or not blow cold air at all, it was in the shop 2-3 times for that. Now my car hesitates when speeding up and you can feel it jerking into gear when it shifts between 1st and 2nd gear or 2nd and 3rd. For this reason I had my transmission fluid replaced and an additive put in and was told this should take care of the problem. It has not!! My next step is to take it back to the dealership to find the problem. Is there anything I should know about concerning the transmission jerking, recalls,etc..?
