Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

My low beams will go out without any warning, not consistent. This happens on highway or city. They will come back after a few minutes, or sometimes days. I still have high beams

Car has been continually overheating, radiator has been flushed and refilled with fresh coolant and new thermostat was bled. Car is fine while driving over 50mph but overheats when in traffic at a light. Driver back window motor is out, the window goes down but won't go up. The car stopped abruptly while driving and had to pull on the side don't know what happened but it won't start up but the lights come on inside the vehicle. I have had trouble since purchasing this vehicle. GM needs to take this vehicles completely off the road they have stop making them and I can see why they're nothing but money eaters.

Driving down the road early morning or late night my low beams will turn off and come back on 20 minutes later, this is a very big safety issue. I have replaced fuses and everything possible to do with headlights and they still continue to fail. I have had my car looked at by a certified mechanic and they will not mess with it due to the fact that there are to many wiring harnesses. I have read every forum for Grand Prix with low beam issues and nothing solves it. This issues needs to be resolved.

R reading some of the complaints that have been submitted, I don't know where to begin or if I have enough characters to express my frustration with my 2006 Pontiac Grand Prix GT supercharged. My recent issue is that the car keeps cutting out and stalling.I took the car to the dealer and spent $110 on a diagnostic after 4 other local mechanics could not duplicate the issue or pinpoint the problem. The result from the dealer's diagnostic was: P0300 multiple misfires; needs 3 coils and ignition module replaced $1090 installed; also has a bearing going out in the super charger and there is a harsh 1-2 shift. I just spent about $1000 getting fuel pump, back wheel bearings, right brake hose, and valve cover gaskets replaced. Rack and pinion had to be tightened although it was replaced twice last year (bad part the first time). I have had power steering pump replaced, water pump replaced, air intake tube/valve replaced. Paid dealer for diagnostic because no codes or indicator lights were on and 4 different mechanics couldn't pinpoint issue. Dealer stated they have up-to-date equipment and code P0300 came up. Car intermittently hesitates to start. Car acts hesitant after car starts after hesitating to start. Interior seats and dashboard has cracked. ABS/traction seems to be failing, car still moves after applying foot on break...slides a little, no immediate stop, even after I have had complete brake work performed (wheel bearings, pads, rotors, hubs, etc.). supercharge switch has been replaced and elbow tube off the motor block (think that is correct, it's an L-shaped small tube). A lot of repairs have been made. The car runs smoothly when necessary repairs are made. Hate to get rid of the car with all the money and care that has been placed into the car. I am not in a postion to purchase a new vehicle but with the miles I don't want to put extensive $. GM won't assist.

Soon after purchase, transmission slips gears coming out of a stop. August 2013, transmission dropped out, driving 30mph. Car was not drivable; no gears. Transmission was replaced. Now one year later, slips gears at 40mph. Headlights went out while driving in the dark. Use of turn signals causes high beams to activate. The cabin fan (A/C and heat) never shuts off. Heat works intermittently. Car seems to shake at times. Feels like a flat tire but when checked, tires are fine. Car rolls when in park, even on flat surface. Car rolls back when in drive, even on slight inclines. Never certain of brakes; at times, works as normal, other times, pedal must be pushed close to the floor to activate brakes.
