This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Thermostat/coolant sensor malfunctioning causing engine fan to constantly run as if the engine is over heating. Some engine exhaust door/flap is stuck open or closed causing check engine light to come on. And or the actuators doors are broken causing windows to fog and obstruct view. Not sure what would cause this issue but I have had to have work done on my vehicle twice for this issue within 3 years.
2016 GMC Terrain SLT, service engine light came on, vehicle stalled many times, restarted but drove and misfired, stalled again, was able to get it to repair garage who I trust. He checked code and said I had to put a complete timing chain kit. Total cost came to $992.36 and didn't have a vehicle for a week due to weekend and a holiday. The vehicle only had 30,763 miles on it at the time but was out of factory warrantee. Reading other customer complaints, this looks like an ongoing problem and I feel should warrant a recall. Additional info such as repair invoice is attached. Please reply when received and thank you for your time.
Vehicle since purchase shows no signs of leak but goes through oil at about 1 quart every 1000 miles max. Check engine light always on, sensors indicate possible faulty piston rings. All were problems in later model GMC Terrains. When low on oil while driving and stationary all lights will light up and engine will go into reduced power mode saying to service stabilitrack. Car will not go above 10 mph when in this mode, sometimes unable to move at all. Goes away after more oil added. GMC Terrain had recalls on years 2010-2013 for all engine failure problems/repairs due to faulty piston rings/oil consumption issues. Numerous 2014-2016 GMC Terrains have claims of the reduced power/stabilitrack problem with no solution, I believe both problems are directly related.
I took my vehicle to ed rinke Chevrolet Buick GMC on 12/27/18, because my driver side window sometimes hesitates when I try to roll it up and down or just gets stuck and does not move at all. This happens when the vehicle is in motion or parked. I was told that this issue was no longer covered under warranty even though my vehicle only has 47,455 miles on it and it would be $99 for them to check it out. I previously purchased a 2006 GMC Envoy which I still own and the driver side window was doing the same thing pretty early after I purchased it. I ended up having to pay over $400 to get it fixed and later on found out there was a recall on that issue (driver's door control panel.) I believe this is a manufacturers defect in the Terrain and L think it should be repaired with no cost to me. Please check and see if other vehicle owners are experiencing this problem as well. I am hoping this issue can be repaired and I am able to properly roll my window up and down in the cold weather we are experiencing now......than you
When driving the car will not respond correctly to the accelerator, delayed response. The car will also not shift correctly (as thought you are shifting manually). While driving the vehicle's gauges will jump up and down followed by the check engine lights coming on. Car will then go into reduced power mode. When pressing on the accelerator the engine will rev and then the car slams down into 2nd gear. The car has been in a GMC certified garage 7 times and out of service while in the garage 40 days and counting. Numerous attempts at repair have obviously been unsuccessful. GM is refusing to by the car back because I bought it at premier Chevrolet GMC in morgantown, wv used with 27,768 miles on 2/5/17.

2016 GMC Terrain will show the check engine, traction control and service stabilitrak lights after gauges jump up and down. Vehicle will then go into neutral and then suddenly slam into 2nd gear. This occurs at high rates of speed on the interstate, as well as, normal roads. The vehicle will then stay in 2nd gear and will not go into another gear when it is placed in manual either. Sometimes, after restarting several times, it will drive normally. Other times, it will not start once it is turned off. I have had it to the garage five times in the last month. The starter wire and starter relay have been replaced, loose ground wire tightened, and the ECM replaced yet the car continues to repeat the same cycle. Car currently has 53,300 miles on it.
The contact owns a 2016 GMC Terrain. While attempting to start the engine, it failed to start. The vehicle was towed to the dealer (suller GMC located in farmington hills, Michigan) where it was diagnosed that rodents had eaten the electrical wires. The contact was informed that the wiring harness was produced using soy based materials, which attracted rodents. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 11,000. Updated 09/06/17
The digital clock does not keep accurate time, even when it is reset. Every time the vehicle is started the clock is several hours off. The dealer that sold us the vehicle claims this is due to the fact we do not have an onstar subscription. I contacted both GM and onstar, and both stated the clock issue is not related in any way to onstar
