What 1998 Pontiac Bonneville owners say
Most recent owner complaints, unedited.
The back two cradle mounts on both sides rusted out and mounts pulled through the cradle causing the steering to become loose filling and causing steering to be out of alignment and when hit brakes front would dart one way or the other and lots of noise coming from under vehicle from cradle bouncing when hitting bumps tried the find one in junk yards and all are that way.
I was driving on the new york thruway and all of a sudden, my car shut off. I had to power steer, no power brakes, the fuel gauge read no fuel and the bells went off. I had to try to get to a safe place and restart my car. This has happened many more times. I can be going 25mph or 70mph; I can have the cruise on or off; I can have the heat or A/C on or off, it does not matter; in all cases, the engine shuts off when I am not expecting it.
On multiple occasions I have pulled to a dead stop at a light and during the idling time the engine shuts off and it will not start again. Very embarrassing set of trips to nearby grocer. ..
As I was driving along the engine, power steering, and brakes failed. I had to restart the car and hopefully resume driving so the car coming behind me did not crash into me. This has happened numerous times since including times while on I-95, I-81, rural mountainous roads (which resulted in my car rolling backwards), and city traffic. I have taken it in numerous times to my mechanic and he has not come up with a reason as to why this is happening. I am given no warning by my car that this is about to happen. The warning bell chimes and the car fails at the same time. This happened last evening and the car behind me had to swerve to avoid a crash. Please add my car to your recall or give me some kind of answer to take to my mechanic.

Motor was waterlocked broke starter...intake manifold gasket replaced.....oil changed due to coolant contamination...replace antifreeze...total bill labor and parts... $1387.99..gm has numerous service bulletins on this issue...why has a recall not be issued for this problem ??
The air intake gasket has failed for 2 reasons. 1 factory tightly put the bolts on to tight. 2 plastic gasket and plastic manifold parts do not meet government safety standards for, failure avoidance, because of materials used to connect the plastic to mettle creating a dangerous situation.
