What owners say
The car lost all power while driving on several occasions. It would just quit and I would have no brakes or steering and all gauges would shut down. Sometimes it would lose power and then it would come back on while I was still driving cutting in and out repeatedly. It happened a lot when I was idling at a corner and then would start through the intersection. It would quit going through the intersection. Sometimes it wouldn't start after driving it a short distance. After it sat for a few minutes, a few hours or sometimes overnight it would just start like there wasn't any problem with it. It didn't sputter or act like it wasn't getting gas or anything, it just wouldn't do anything and had a total loss of all power. We took it in for repair several times and they could never replicate the problem and diagnostics didn't show any problems that would cause this issue. I asked a couple of times if there were any recalls and the service garage said no. I finally quit driving the car because I was tired of being stranded and with taking my chances with it loosing power driving down the highway or through intersections in heavy traffic. It sounds like the same issue that they are currently recalling some gm models for because of an ignition switch spring but bonneville aren't on the recall list.
While driving my vehicle lost power. I shifted vehicle to neutral and attempted restart. Engine restarted. Continued driving when drive over bumps, buckles in payment engine looses power. All needle indicators drop to off position, car starts to slow down, steering looses power, all lights go out as well. This is a condition that has become increasing more dangerous as speeds increases. I had vehicle checked out and mechanics are unable to diagnosis. I previously owned 2001 pontiac bonneville as well which did the same when driven over bumps, or imperfections in the road. This is my second complaint, and I have not heard anything. I previously stated I believe this problem is related to recall gm has recently acknowledged for some cars. I don't believe they have included all vehicles that contain this problem. My previous odi (your confirmation number (odi number) is: 10564622 )this problem should be noted, and included with safety recall by gm and the federal safety agency.
While driving my engine lost power completely. I had went over bump in the road and the vehicle lost all power. I place the car in neutral, and able to restart and continue driving. Hit bump in road again and engine lost power again. I was fortunate to be able to pull over. Restarted engine and returned home. Had repair shop check vehicle for diagnosis and they were unable to resolve issue. Neither was gm dealer. I have had this happen everytime I go over bump in road, usually at speeds over 40 miles per hour. I had same problem with 2001 bonneville. I saw gm recalling 2005 g5 with same problem. I believe my problem is related issue and is a safety hazard that should be handled similarly by gm. I do not believe the problem is limited to g5 and cobalt. As I stated 2001 and 2003 bonnevilles have same issue.
Acted like it was running out of gas, loss of power and speed. Only 50mph when a boom in the engine, pulled over popped the hood latch, saw smoke, exited car as flames came out of the hood. Called 911.. Car burnt to the ground. Witness stopped and told me that there is a problem with faulty fuel lines .
Tl*the contact owns a 2005 pontiac bonneville. The contact stated that while driving approximately 65 MPH the engine started to lose power. When the vehicle stalled it would not restart and smoke started was coming from the engine. The vehicle was towed to a dealer who was unable to diagnose the failure due to the sensors melting. The vehicle has been repaired. The failure mileage was 63,635.
My upper intake manifold leaks engine coolant into the combustion chambers and into the crankcase. The egr tube melts the upper plastic manifold I have had the upper and lower intake replaced for this issue once before with gm parts and it happening again. If it not fixed the coolant can contaminate my oil and lock up my engine when traveling down the road and possibly cause me to crash. If the engine locks up I will lose power steering and braking ability.
When the right front wheel passes through standing water moisture is deflected onto the serpentine belt. The serpentine belt slips causing a loss of power steering which renders the vehicle not able steer until the serpentine belt stops slipping. Multiple occurrences.
Tl*the contact owns a 1996 pontiac bonneville. While driving between 35-40 MPH, the vehicle gradually lost power and shut off. When the contact attempted to restart the vehicle, it backfired. The vehicle was pushed to the side of the road and towed to the dealer. The dealer stated that the upper intake manifold was cracked and would cost $503 to repair. The current mileage was 176,000 and failure mileage was 105,000. Updated 04/08/08. *lj the battery was replaced due to the vehicle not starting.
Heard a "popping" noise, then lost power steering when turning left. Right turns work fine, but no power steering to the left.
