2003 Pontiac Bonneville Electrical system Problems

“My car shuts off while driving. I notice it because power steering is hard to use and RPM's go down to zero and car has shut off. It started up again. This has been a real problem. Dealer tested car and said it was a crankshaft sensor. I replaced the crankshaft sensor and the problem continues. Cam sensor replaced too. This is a safety issue. No one knows why the car shuts off when it wants to. Now the car still shuts off while driving, but also it takes 2 to 3 times to restart. Still trying to figure this out. It is august 2015 and I need this car. Is this a recall issue?”

“On 8/1/11 while driving I heard a loud noise like I had been hit by something so I pulled off the highway and noticed that my left rear window had dropped down by itself and I could not raise it by activating the switch. Gm replaced the operator. On 12/13/13 my right front window operator failed and I shared the cost of the repair with GM. Now on 1/19/14 my right rear window operator has failed. I searched the internet and have found that many people have had this same problem. This vehicle has only 7300 miles on it and in my estimation should not have these problems. …”

This is a huge safety concern for a few reasons. …”

“Pontiac Bonneville 2003, car would just turn off while we were driving. We didn't realize it was turning off at first, we just thought the steering and brakes were becoming hard to work. We would have to pull over and turn the car back on.”

“I have a 2003 Pontiac Bonneville. The blower motor had intermittent problems before going out. I took the vehicle to the local dealer who stated that the wiring harness connected to the blower motor for the heat/AC had melted and required replacing. I was lucky the car didn't catch on fire! This is a very expensive repair. A very quick search on the internet revealed that this is a common problem not only with Pontiac but many GM cars and trucks. Sounds like GM has installed inadequate wiring and all vehicles with this substandard wiring should be recalled and wiring replaced. …”
