2012 GMC Terrain Vehicle speed control Problems

“My Terrain is stalling really bad some days and sometimes no problems at all. It does it more when going into reverse, I have to keep giving gas to get backed up. It has also died on me when I slow to a stop like at a light. This is really frustrating!!”

“Summary: I had to decide to brake or shoot through a yellow light, going about 35 MPH, I braked! All of a sudden I heard a clunk and then alarm ding from the dash as well as message service stabiltrak then reduced engine power . I was unable to go any faster than 25mph. I drove in this mode for about 2 miles taking the back streets to my destination. At destination shut vehicle off to see if this would reset something, it did! It was super scary. So now terrified to brake hard.”

“Vehicle began to use excessive amount of oil and idel up and down and sometimes even shuts down. After about 3 months while driving on the interstate it began to shut down while in motion. I called for someone to check the vehicle out and he arrived called someone to check the vehicle and he actually told me it seems to be the motor gone bad but he asked would I drive it back home if he followed behind. It literally scared me and my 4 children to death when it shut down while in motion with that kind of speed so I don't trust putting my children in it now. I don't think its safe at all. …”

“On 8/2/12 I purchased my Gmc Terrain brand new in ashland city, tn. I moved to west palm beach in october 2012. The current miles on the vehicle are 44,039. I got an oil change, filter and multi-point inspection on 10/24/13 by the local Gmc dealer. On 10/23/13 I took my vehicle in to have a recall repaired at schumacher buick/Gmc. The recall # is 12312. A month later the vehicle would lunge sharply forward while driving and a heavy shaking vibration (both while driving and at a stop) below my feet in the vehicle (floor board). …”

“I started out driving on highway road at approximately 5:45pm traffic was moderate, my speed was about 30-35 MPH. All of a sudden I heard a clunk and then alarm ding from the dash as well as message service stabiltrak then reduced engine power . I was unable to go any faster than 25mph. I drove in this mode for about 2 miles in traffic, when reaching open highway (no traffic) the vehicle would not shift by itself. I had to accelerate then let off the gas, tap pedal then the vehicle would shift. I was able to do this multiple times until reaching about 45mph. …”
