POWER TRAIN - AUTOMATIC TRANSMISSION

 Was driving slowly in a parking lot and was starting the turn into a parking stall when the steering became very difficult and the vehical had difficulty moving forward. transmission had gone into 4x4 low without anyone pushing the button on the dash. i had a 2007 canyon and it did the same thing about 3 times while driving in a parkade. when i contacted the dealer there comment was to bring it in while the incident is occuring. when i did take the 2007 in for service they could not find anything. i will mention the incident on 2009 when it goes in for its next service.

 Tl* the contact owns a 2009 gmc canyon. when she slightly struck the gear shifter at 20 mph the gear shifted from drive into the reverse gear. she was able to regain vehicle control. the vehicle was taken to an authorized dealer for inspection. the technician could not identify the cause of the failure. the failure mileage was 3,400. the current mileage was 3,700.
