| I purchased vehicle use, with 384 miles. vehicle transmission became very loud, whining, growling, making clunking noise when shifting; downshifting at times produced runaway shifting, clunking and slipping. took it to one chev. dealer and service writer said he had a chev p.u. just like mine and it didn't make those noises. went back again and dealer found a service bulletin that applied to my transmission. they ordered parts, installed them, but no change. went back again and the service shop and they said there was nothing wrong with the transmission and there was nothing more they could do for my p.u. i went to another dealer and they said it needed front and rear planetary gears. parts were ordered and installed, again no change. went back to the dealer and they drove my p.u. the service manager said there was nothing wrong with my p.u. ! i spoke with a district specialist at g.m. and she said she would contact the dealership! it is now june 5, 2012 and i again called gm customer assistance and they said the woman who had my case no longer works in that department and they would assign another specialist. she/he would call me today, maybe tomorrow. i told them enough is enough and i wanted another vehicle! | |||

| Just seconds after having come to a complete stop, the transmission shifts while rpms increase causing the vehicle to overcome the brake pressure and truck to move forward abruptly. this caused me to roll out into the lane of oncoming traffic and strike a vehicle as it was passing. | |||

| This vehicle has several defects that gm claims as normal. 1. truck randomly lurches forward when started in park. gm says this is normal make sure you apply parking brake when parking. 2. drive train clunks when decelerating into 10-20mph range and accelerating again. gm says this is normal due to tolerances and accelerated in four wheel drive vehicles. 3. vehicle drain train randomly makse a bang or clunk noise when accelerating from a stop. gm claims this is also normal. i have purchased this truck new in november 2011 and it has been in the shop five times. each time dealer checks repair for defect and gm sends back bulletin saying no repair condition normal. dealer says a handful of trucks have come back with this similar problem. i can not believe gm accepts this defect as normal. | |||

| This is a dealer demo vehicle, first 2235 miles were demo. during my first morning (12hours after picking up at dealer) of ownership i was descending down a hill with the cruise on, and the vehicle proceeded to over speed approximately 5-7mph. i travel this hill both ways to/from work daily and this happens everytime. i though this might be an abnormal adjustment within the computer/etc so while taking in to the dealer for a tpms (tire pressure monitor system) issue i mentioned the overspeed issue to the service write up and they said that it was normal. i don't agree, but maybe it is. it does adjust back to normal cruise set speed but is unique. i had a 2002 dodge ram 1500 previously and it did not do this, and i have drove otr (over the road) semi-trucks and know the difference with overspeed being normal and abnormal. i would like this to be looked into, as it could be a hazard that could lead to unsafe situation. | |||
