2014 GMC Terrain electrical problems

Filed Aug 21, 2025 · Brakes, Electrical · TN

ABS Brake problem and have tried to get it repaired for over 3 months and cannot seem to be able to get the part and call GM with no help. Can not tell me when or where to buy the part. Nobody seems to be able to get a new part and no help from GM. If there is this many problems that there is no part left available it should be a national recall.

Tensioner issues keeps breaking the timing chain. . Replaced twice at own cost. Fuel pump/ loss of power while driving. Back up camera doesn't work sometimes. Screen goes black. If key is left in the ignition it starts itself. If you try to use a car charger for a phone the AC shuts off and a "systems error" message pops up. This happens alot. It's an ongoing issue since I bought the car in Feburary this year.

The actuator that controls the blend door / recirculation door (moves the air from defrost to floor to vent) does not last more than a year in my vehicle. I see on the GMC Terrain forums that it is a common problem. It is a danger when defrost is needed on the windshield, and it doesn't work.

My car had been needing at least 2quarts of oil in between oil changes which I have done every 3000 miles. The timing chain is bad which is caused by excessive oil consumption. The service power steering and stability track light comes on it its messing with the transmission until I disconnect the battery and reset it, and it also leaked inside my glove an f the passenger floorboards

I was out of town and had gone to the store and when I got back in my vehicle and it would not start. After, letting it sit for 4 hours it finally cranked up. The battery and fuses were fine. No lights came in on my dash as a warning that something was wrong. This has happened to me before. A diagnostic was run and it throwed out no codes.

Key is locking in the ignition. When turning on the car the screen does not display, stays blank. Cannot turn the radio on or off or up. It's happening more and more. It continues while driving. The gear shifter sticks in park and is extremely hard at times to get it in reverse or drive.
