What 1993 Pontiac Bonneville owners say
Most recent owner complaints, unedited.
1993 pontiac bonneville (3.8l) rear engine cradle rotted at all for bolt points causing rear of engine cradle to fall out of the car causing steering issues and an eventual loss of steering. 1.) driving down normal paved city street. Began turning a corner. (extremely lucky this happened at low speeds on a city street. If this happened on the freeway serious injury could have taken place) 2.) failure occurred once. Any failure causing steering loss is one too many. 3.) not yet repaired in searching the internet I see that gm has issued recalls for this exact type of failure on the pontiac grand prix, but I do not see one listed for the bonneville. In searching the internet I have found many other reports of this occurring. This was critical enough to issue a recall for the pontiac grand prix, then this should be serious enough to include the bonneville as well.

Tl*the contact owns a 1993 pontiac bonneville. The contact took her vehicle to midas for a routine oil change. A few hours later, the vehicle shut off while driving. The vehicle was towed and the technician stated that the vehicle's oil was black. The technician stated that the oil change was not the cause of the failure, but could possibly result from engine failure. As a result, midas fails to reimburse the contact. The vehicle would start, but made a loud knocking noise. The contact has the receipt and paperwork from the event. The VIN was unavailable. The current and failure mileages were 233,065.
I own a 1993 pontiac bonneville, VIN [xxx] with just over 160,000 miles on it. On the evening of april 6th, 2006 my wife was driving this car near our home. She was at a stop sign on ortman road and as she pulled onto cherry creek road she heard a loud clunk. At the same time she lost all steering ability. When she turned the steering wheel it just spun in circles as if it were no longer attached to anything. I was called and went to see what had happened. Upon inspection of the vehicle I saw that the sub frame and motor had dropped down about 6 inches. There are four bolts that attach the sub frame to the body of these vehicles. The bolts were all in place and in good shape. Each bolt has a washer, which retains the sub frame to the body of this car. On my car the washers corroded and wore to the point that they would no longer retain the sub frame. The bolts pulled through the mounting holes of the sub frame, thus allowing the engine and all related components to drop about 6 inches. When this happened the shaft from the rack and pinion steering to the steering wheel pulled apart, thereby leaving the operator of the vehicle with no ability to steer. On friday april 7th I called public service garage in marquette mi. And spoke to the service manager. He said that there was ??no recalls for this problem and that he sees this a few times a year??. I called and filed a complaint with pontiac also. I have been told that it is ??very unlikely that pontiac will do anything because this only happens in the midwest where the winter roads are salted?? Thus causing high rates of corrosion. This would have been a five-minute fix if it were done before the failure. You could pull the bolts out one at a time and simply remove the old washer and replace it with a new one. I feel that the owners should be made aware of this possible problem. I also believe this problem exists on other makes and models of gm vehicles. *nm updated 07/16/2012
Went to the store and when I came out my car would not start, the security light was flashing. I read the owners manual and it said to clean the key and checks the fuses. I did both of these and still no start. I called a gm dealer and told him what had happened, he said that the car is not recogoning the key and that is why it wont start. The key has a chip on it, now this is in no way something that was caused by neglect, it is from a defect in the key, yet gm will not pay to get this fix and get the car back on the road.
Tire defect. Groove developing on sidewall approximately in the middle of the "brand" and "model" lettering. Looks as if the tire has been rubbing against something, but is on outside of tire. This is happening on two tires. One passenger rear, the other, driver front. Possible belt separation?
