| Vehicle gives a service throttle starting disabled message and promptly shuts off the engine. if you wait 5 minutes the car will restart and perform as usual.....until the next time. shutting off the engine at interstate speeds is incredibly dangerous and is going to result in someone being killed. based upon internet searches this appears to be a known issue, but gm will not proactively fix the problem. *tr | |||

| Purchased vehicle on 9/6/2012 used with 27,479 miles. on 9/19/2012 with 27,960 miles, i was accelerating on an onramp getting on a highway and two messages appeared on my dash: reduced engine power and service traction control as well as the check engine light. experience rough and hesitant shifting between gears and could not go faster than 35mph. was able to safely navigate home on side roads. i took it to the dealer i purchased it from for service and was told it was reading code p2138 and the throttle pedal assembly needed to be replaced. the service was covered under the dealer's warranty and i was set to go. flash forward to 10/24/2012 with 29,355 miles, i was driving on a side road and the same messages came up. i called on star and they performed a diagnostic which resulted in the computer reading codes p2138 and c0242. experienced out of control wheel spinning and sensitive braking. took it to a dealer in the area i was currently in traveling for business and they could not diagnose with any issue. all codes and lights were not engaged. i still did not feel safe driving my vehicle due to problem with accelerator and had towed to the purchasing dealer near my home. they also could not diagnose with any issue as they could not duplicate the error. this is a serious safety concern and a problem (especially on the highway) with a popular model. i have also filed a complaint with gm on this issue and am hoping to have it resolved immediately. *tr | |||

| I was turning left into a driveway going no more than 7 miles an hour, because i was following a car, when i heard a large grind then pop. i parked my car and knew immediately the transmission failed by the fluid trail and part left behind. i took it to a dealer and luckily it was covered under the power train warranty. a week after receiving my vehicle back the alignment was off, driver-side headlight socket caught fire, i have labored start up, have stalled on the freeway! and have stabilitrak, airbag, and reduced engine power error codes that randomly appear. | |||

| In june 2010 i was driving on the interstate 90 west toward denver co. the terrain was steep and winding and due to heavy traffic the pace was fast. the traffic ahead of me began slowing and i began to slow by steady light pressure on the break pedal. my breaks heated up fast and i found myself without breaks for a short period of time due to the rotors feeling as though they were warped and the front end started vibrating. i down shifted to 3rd. gear but that was not enough to slow me enough so i downshifted to 2nd and this still was not enough to maintain a downhill speed to keep from having to use the brakes. finally i shifted to !st gear to maintain the safe speed that i needed. the problem seems to be that the car freewheels so excellent that even on lower grades as experienced in the carolinas in october when we were there the car is almost impossible to gear down so as not to overheat the brakes when trying to maintain posted speeds in mountainous country. i discussed this with solomon chevrolet in dothan where i get the car serviced and the dealer from whom i purchased the car. they had no suggestions but assured me there was nothing they could do dealership wise to help me. i feel it is a very dangerous situation which does not surface unless you drive in the mountains. | |||
