Vehicle shut down at 55 mph while inside eisenhower tunnel Colorado. Husband calmly placed automatic transmission into park and restarted car. This type of incident has happened twice again since the original incident. Prior to the first incident car lost power coming up the grade at 65 mph. We were forced over to the side of the interstate. After waiting for a tow (which was slow to respond) approximately 20 minutes, tried the ignition and the engine turned over. Never received an adequate answer from dealer. Suspect fuel problem with altitude, or ignition problem. Incidents always seem to happen at higher (55+) speeds.

Driving on the interstate going about 65 mpg when all of a sudden I lost all engine power and the engine stalled. Check engine light came on and traction control system remained on. Pulled over and shut off the engine. Restarted the engine, lights remained on and was only able to go about 15 mph. Had to drive it very carefully about 10 miles into the next town. No shops were open at that time of night. Had to stay the night and took it into a shop the next morning. Error code said that the mass air flow sensor was bad. Replaced and drove it around for about 5 miles. Seemed to be running ok. Drove not even 60 miles and the same thing happened again. Took it into a sister repair shop and they replaced the other part of the mass air flow sensor. Was able to drive to my destination and back with no real issues. Here it is 7 months later and driving on the interstate again when the same issue happens. Check engine light came on and traction control light came on. Was able to get off the side of the road but this time. I couldn't even get it to drive 3 feet. Sat on the side of the interstate for 2 hours at night waiting for a tow truck to come get me. Got it into a shop the next morning and same issues. Needed a new mass air flow sensor. Replace and picked up but then the engine started getting really hot. Watched the transmission fluid go from 108 to 258 degrees in a matter of minutes. Pulled off the road and watched the fluid bubble out of the overflow. Got the engine to cool down a bit. Started it and drove 4 miles and the same codes came up and the engine did the same thing. Had the car towed back to the shop and was told that the computer needed to be replaced. Did that and it now surges upon start up. The super charger is not registering as being either hooked up or working now. I am being told that there are several issues that could be causing this.

I have 36,378 miles on my 2006 Pontiac Grand Prix and have taken it into the shop for rotors 2 times now. They have turned the rotors but the brakes are still not right and now of course its out of warranty. I have never had a problem with rotors in my life. This is not normal wear. I also have a gas tank problem when I fill it up, it will overflow. The service provider (osbournes in dubois, pa) say they can't get it to do it but it happens to me everytime I fill up the tank.
