A faulty crankshaft position sensor caused the loss of steering and braking on numerous occasions until the problem was diagnosed. The same conditions as a faulty ignition switch. Yet the crankshaft sensor is common on all autos. Thus all autos that use a crankshaft sensor are unsafe.[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

The car was parked in a parking lot. It caught fire 30 min after it was parked and burned the entire engine compartment. The fore department stopped the fire before it spread to the rest of the car. It was a good car previous to this instance. We maintained the car well and had it looked over by a mechanic monthly. We will never own a pontiac again.

Driving to work as normal and took off from a full stop when all of a sudden the car was going nuts trying to catch a gear. Service engine light blinked than stayed on and now when driving between 1st and 3rd gear car sputters, shakes, slams into gear hard and I need to keep giving it gas to get it to catch so I move and don't get stuck in the middle of making a turn. It is a 99 grand prix se 3800 engine sedan and I brought it to my good friend who owns a shop and the computer said it was a c1 misfire solenoid or something like that. On my engine, the left side has 3 things that 2 spark plug wires goes into each and are labeled 1/3, 2/5 and 4/6 (might be wrong on numbers). The code was saying the first one that says 1/3 was bad causing the misfire. We changed the part and the service engine line went off and car drove fine. The next morning I went to go work and at the first light, I go to take off and it starts shaking and sputters and becomes almost impossible to drive. During this the service engine line blinked than stayed on steady. Now the car has trouble catching a gear from 1st to 3rd and it feels like a roller coaster just trying to take off from a stop or during heavy traffic. I replaced everything else on the car and give up with problems. There has to be a defect that pontiac won't admit.

Transmission slip's real bad. The car rocks back and forth when slowly accelerating. What will be done about this? This my only form of transportation.

Dt: the car is dying without warning. There are no lights on the dashboard that light up when this happens. After the vehicle dies, the battery light is coming on. This has been happening for over a year. The car has been in the shop over 15 times for this same problem. The car has not been fixed at this point. Also, tried a different dealership, and they could find the problem either. The consumer says her car is a death trap, and this is happening anywhere/anytime. This past weekend the car died 4 times on the freeway. Consumer has to wait 15-20 minutes before the vehicle will start back up. The consumer has been in contact with gm and have registered two complaints on this car. Speed is not a factor and also dies while in park.

Multiple repair problems--air plate was repaired--new engine installed after having only 54,000 miles with regular oil changes--electrical problem with radio display--now back passenger tire/possible axle, strut; sounds like back tire is about to fall off upon hitting bumps in the road/driveways or turning. I have not had this checked out-am now unable to drive vehicle .

Rpms jump 100 - 200 rpms in the matter of a second or two while car is accelerating and the car "surges" or "bucks" while rpms jump up and down. Tcc solenoid in transmission thought to be problem.

Intermittent transmission problems. Seems to occur more when the car is hot. Transmission "slams" when upshifting into any gear.
