| Transmission went out when i used the passing gear. gears began slipping and i could not pass the vehicle. i pulled over and tried to put car in reverse and it would not engage. was able to drive to next town about three miles in first gear at abot 25 mph.this occurred on a vacation trip to florida. the car was towed to a pontiac dealer in manning sc santee motor co. inc. 452 n brook st.zip 29102 phone 800-948-6080. i doubt that i have used the passing gear more than a dozen times during the life of the car. it hard to bekeive that the transmission would go that easily after only 62,00 miles. i have kept up with the service on the car faithfully having had my mechanic give my car a thorough check before taking this trip even buying new tires although i still had faurly good tread on them. *ak | |||

| The problem started about 2 weeks ago, car took off and brakes were as hard as a rock, the only way to control car was to put in neutral. this last time i was on a freeway in southern calif. and the car took off again and i ended off the freeway in a vacant field to stop the car. i was afraid of going into a residental area. the first incident was reported and the car was checked out at a local gm dealership, and nothing was found. the car is there now again and they have found nothing. the car has an extended warranty and they have had it for 3 days.oddly enough when i called aaa to tow me out of the field this last time the dispatcher stated that her mom's buick does the same thing. gm is making it sound like this is unheard of and they have no idea what is going on, yet on the internet there seems to be other cases. *ak | |||

| I purchased this car used from a dealer in 2001 in michigan. (i don't think the air conditioning ever worked ). within a few months the traction control went out. it would be on, when the car started, but within driving 300ft. would go out and could not be turned back on from the button. a few months after that all of the dash lights went out when ever you turned on the head lights. this was due to a bad switch & a short. then the cruse control went out. a few months after that we had to replace the head gaskets due to the engine over heating by an unknown cause. 1 month after that we had to replace the engine after throwing a rod and cracking the engine block, due to the fact that there was still fluind in the engine from melted manafold.( this all took place between nov. 2001 & jan. 2002) after that the ignition had to be replaced because one of the wires was severed due to the wheel tilt. (we would tilt the wheel & could not start the car). in nov. 2002 the transmission started to slip, we had it replaced. then all at one time (2003) the battery went dead, the timing chain had jumped a tooth, the cam sensor, and the spark plugs which had been changed a few weeks before. a few weeks after that the engine overheated again due to a leak in the coolant resovoir bottel, this caused the head gaskets to blow again. it is now 2004 we have an ongoing electrical problem. since mid 2003 we have gone through 3 pcm & 3 proms due to the fact the they kept frying ( a result of a bad ground that still can not be found), an altanator due to the fact that it had spikes. the check enging light would constantly come on & when the codes were pulled the egr vlave was listed, we replaced it and still the check engine light came on due to a still bad pcm. now whenever we turn on the blinker the voltage gage moves in time with it due to a short. the rpm's surge at times while car is in motion or at idle, causing the car to satll or backfire. the cause is still unknown. *ak | |||

| Traction control turns off when the vehicle is in motion. randomly occurs after traveling several hundred feet. higher incidence at time of automatic gear shift into 3rd gear. can not be reset by traction control switch - must come to full stop and turn off engine. with rapid acceleration and maintaining speed at 55 mph or above traction control off light will not come on. drop down to ~50 mph and light comes on. gm dealer claims npf but problem occurs almost each time out for me. another dealer claims replacement of tc module necessary - service tech tells me it is common problem to 95 & 96 bonnevilles.*ak | |||

| In february 2010, driving at 5 mph while making right turn on bumpy blacktop, the engine fell out from under car causing steering to become inoperable. car was towed from scene. upon investigation it was found that 4 (rear) of 6 bolts holding engine cradle to uni-body frame pulled through rusted retainers. all (6) bolts, retainers, spacers and insulators were replaced. the steering linkage was reattached and the clock spring coil kit was replaced (clock spring was torn when steering linkage separated). this incident caused a lot of concern because it could have happened at any speed. towing, repairs and parts cost $805.14. 4 months later the steering rack was found to be leaking and was replaced at a cost of $450. no parts have been retained but photos of the bolts in the frame with the engine sub frame hanging are available. naturally the retainers that failed are gone because they fell off when they failed. the engine did not fall entirely from the vehicle because the 2 front bolts were still intact and the upper engine mount held the engine sub frame 2 above the road surface. | |||
