Acadia 6-cyl

  • 19,000 miles


2010 Acadia transmission and traction control safety problems. While driving 70mph on the highway, the traction control system alarm came on in addition to a flashing stability control and ABS warning lights. The rear passenger wheel locked up, the transmission downshifted into 3rd gear causing the vehicle to veer into the right lane. Additionally, we have been having power steering pum problems with the vehicle which made the vehicle difficult to control in this circumstance. Fortunately, there was no other vehicle in the right lane and maanged to pul the vehile off the road. I had my family in the vehile at the time which made everyone very scared for their safety. The vehicle was turned off and restarted which erased the ABS and traction control warnings, but the engine check light remained on and was unable to keep the transmission in drive. The dealer replaced some ecms, but could not fix the power steering issue. Three weeks later, the transimission started shifting hard and after 2 visits to the dealer is not being ivestigated for another ECM failure. The electric systems and power steering issues make this is a very unsafe vehicle.

My 2010 GMC Acadia rolls backwards on inclines even though the transmission is in drive. I have driven automatic transmission vehicles for years and in my experience they are not supposed to roll backwards in drive. If anyone is behind the vehicle when this occurs they could very easily be crushed. The dealership acts as if this is normal behavior but it is not and they should be required to fix the problem.

2010 Acadia front wheel drive, when in drive or in park on incline the car will roll backward or forward depending on which way the incline is. It does not hold when you move your foot from the brake to the accelerator while sitting at a traffic light or when you are parking. I have had the car bump a passenger when they walked around the front of my car to get in and I had placed the car in park and took my foot off the brake.I have owned many cars and vans and have never experienced this type of problem and it occurs often and the dealership service department is ignoring the problem. If an elderly person or child should happen to be close to the car when this happens it could cause serious harm.

  • 9,400 miles
The contact owns a 2010 GMC Acadia. While the contact driving approximately 55 mph in first gear, the transmission failed, and the rpms began to increase. The check engine warning light illuminated on the instrument panel. Whenever a right turn was attempted, the vehicle stalled. The vehicle was safely driven to a location to be parked and upon restart the vehicle momentarily operated as normal until the failure recurred. The vehicle was towed to an authorized dealer where the technician stated there was a transmission failure. The failure occurred after the dealer previously replaced the transmission. The VIN was not available. The failure and current mileages were 9,400.
