 Tl*the contact owns a 2005 gmc canyon. while driving 30 mph on a wet road, the wheels spun and caused the vehicle to tailspin. the contact crashed into a tree and damaged the rear end of the vehicle. he took the vehicle to a body shop and they repaired the rear end of the vehicle. there were no other repairs done to the vehicle. at the time of purchase, the contact asked if the vehicle had post-traction. the dealer stated that it did; however, the contact later discovered that the vehicle did not have post-traction. whenever he drives the vehicle in the rain, he has to drive approximately 20 mph to avoid tail spinning. the current mileage was 38,000 and failure mileage was 30,000. updated 10/16/08 *bf updated 10/21/08. *jb

 Dt*: the contact stated while the outside conditions were freezing the linkage for the transmission froze as well. this resulted in the inability to change gears until the ice melts. the contact stated by the time the vehicle would arrive at the dealership, the ice would melt. therefore, the vehicle has not been seen by the dealership.

 I have a 2005 gmc canyon 4wd cc p/u . this p/u was purchased new in may 2005. the window sticker clearly lists an auto locking differential under standard equipment. in november 2005 gmc sent a letter to me which stated that this vehicle does not have a auto locking differential. as of this date (2-2-06) gmc admits that the window sticker is wrong, but other options were added to make up the difference. i don't know how this could have been done. gmc also is not willing to do anything to correct this mistake made by them. *jb
