I'va had my 03 pzev for 1 month now and i already have a problem. heres the scoop i have an 03 centennial zts and, yesterday i went o my bank on my lunch hour from work. On the way back before i got onto ia highway i noticed that my speedo was all messed up. When i let off the gas it would drop to 0 then when i hit the gas again it would shoot back up to speed. then when i got on the highway i got about 1/4 mile and my instrument panel lit up like an x-mas tree then fuel cut. wouldn't go when i hit the gas. I pulled over and it wouldn't start back up. Get this I ONLY have 1620 miles on the car and its dead. Called 24 hour roadside and had it towed to the dealer and im waiting to hear from them to find out whats worng. Anyone else have any troubles????? Whats your input?
