| I placed the vehicle in park on a level surface, i left the yukon running and i got out and walked my great niece to a building about 30 feet from the vehicle.. i then turned to see the yukon backing up on this flat surface, i ran to try and catch it but it hit a building and then came forward at me. i had to jump out of it's way and then chase it down. when i jumped in and hit the brake i then noticed it was in m1. i took it to a local gmc dealer who checked the transmission but reported finding nothing. i am now afraid of this car. how do you know when it will vibrate or jump from park to reverse again. this needs checking into. this yukon went both backward & forward. | |||
