I have had this car since it was new. 3 times it has completely died on me while driving, at about 70k intervals.

Once time I was driving down a mountain road and it shut off. Second time I was making a right turn to get onto the highway. Third time driving down a random street.

Whether it's an ignition switch or transmission problem, I don't know. It just completely cuts out. No harsh grinding sounds other people complain about, I'm just worried it will happen at the wrong time since I drive on the freeway a lot.

Update from Jul 13, 2014: When I contacted GM they forwarded it to a local dealer. Service Manager didn't sound confident he could pin point. he said he'd ask people and get back to me, and never did.

I had to back date this one since I just found this site. I tryed to sue pontiac over this terrible little car. Had problem with it not even 200 miles , clutch didn't like to go into gear ,not just one but randomly any gear. I would alway have to double clutch. Let Me say I owned five manual vehicles before this piece of crap and never burned up a clutch. Any way after the mechanic's said it is a new clutch and needs to be broken in a little,it will smooth out. YA RIGHT!! With a new baby in the car and driving to bethesda MAryand we run into a snow storm and become stranded on the highway. After a hour I finally flag down a off duty police man and he calls a tow truck, we were in a dead zone and cell did not work, incase you were wondering. long story short, I had to pay for the tow,rental and new clutch at 12000 miles on a 1/12 year old brand new car. They said it was operator error and we did not know how to drive a manual. Found a different website that said toyota gave pontiac a generic version of the matrix and that is why the clutched failed, and yes the vibe under neathe says toyota all over it.
