I, the owner of a 2007 Grand Prix sedan, operating said vehicle on a neighborhood street at the speed of 20 mph experienced stalled vehicle. Was unable to steer, brake, and realized the vehicle had stalled while driving. Applied emergency brake in order to come to a controlled stop to prevent crashing into traffic. Turned the ignition key completely off, place vehicle in park, and attempted to restart vehicle. Electric ignition switch continued to try to start the vehicle, taking 3 attempts before the ignition switch allowed vehicle to start. GM must address this or it will cost more than just parts, it will do it again and no one can say where my family and I may experience this again. It was a terrifying experience to have no control while car is in motion with passengers in the vehicle.

While driving at about 35-40 mph my car engine shut off, wheel and breaks too and would not start again. The car was taken to a car shop to be looked at and fixed. Once the car was there it started fine and was able to be driven for short distances before the engine would shut off again. It took about 2 weeks to finally figure out it was a fuse in the engine that was not letting power through. Well, the same problem happened in 2013 summer where the same part had to be replaced again.

Car stalled at operating temperature with no warning lights indicated only indication was hard to steer and hard to brake because of engine stalling. Had car towed to dealership and they did a diagnostic and pin point test. Replaced crank position sensor and ignition control module. The car again stalled on them with no warning light indications only that stated above. The car is a safety hazard on the road because of this issue. The car stalls when warm and no tied to any specific speed. This car has stalled on me several times now at different speeds even at highway speed of 55 mph. Currently have filed a complaint with Pontiac customer service and dealership still has the car and currently not fixed the problem. This issue seems to occur on the Grand Prix for years 1998 to 2007 with no answer to what the problem is. This issue needs to be looked seriously because it puts all drivers on the road in serious harm and could serious accident because of a car stalling at anytime. I have had the ignition control module replaced two times in the last week and the ignition coils and wires along with the spark plugs with the same result of car stalling when car reaches operating temperatures.

The first incident happened while driving the car it just stopped after I made a turn and read disabled due to electronic throttle body. After a few moments it just restarted. The lights and everything still work the car will just not crank back up until after a few moments. This has happened approximately 7 times. I take the key out and wait for about 3 to 4 minutes and then the car will start back up like nothing has happened. I have taken it to a few mechanics, and they were not able to pull any codes, and basically told me to take it to the dealer. Now that I have taken it to the dealer, they have had the car since Monday today is Friday and they are unable to determine what the problem is because the codes don't pull up and the car hasn't done it since they have had it.
