The defroster/ radio control/ heating area stopped working. Upon visiting a mechanic was told they never seen this or heard of this happening before and quoted me over $1,000. 00 dollars to fix stating that due to federal law they have to give an estimate but this problem not being in their system they came up with an estimate based on parts and labor. Upon searching online I found a recall for this issue dating back to 2009 recall number was 09v489000 but was never informed about this and while looking up my car it’s not listed but being a safety issue should still be current which it is not.

20 Electrical System problem

Failure Date: 12/04/2016

I am adding on additional information to my previous complaint #10938600. GMC sca #14159, 14232, 15810, 12313, and my transmission failure all seem to fall victim to excessive heat. I was pulling into traffic when the transmission failed. My Terrain has fallen victim to three possibly four of the five calamities. There is no reason to believe all five will not fail under the same driving conditions. Somehow not once did warning lights come on for multiple engine oil occurances, nor for my transmission failure. I was an hvac chiller technician for 28 years. When I hear ecm referenced, as in sca#12312, I have to ask which values were changed and why. Thermistors and pressure switches designed to protect vital engine compartment components run through the ecm yet no warning. My transmission failed on December 4, 2016, the catalytic converter may be bad, the steering gear is suspect, and the engine warning lights have not done what they are supposed to do. The unnecessarily long delay in addressing the oil consumption issue outlined in sca#14159 probably compromised my engine in other ways. Sca#12313 resulted from gm delaying the repair of sca#14159 for so long. What, why, and how. We know what is failing. Simply replacing the part in kind or similar is not addressing why. How do we keep it from happening again is definitely not being addressed. Safety as well as quality issues are at hand here. Gm has ignored my requests for all information regarding sca#14159, 14232, 15810, 12313, and 12312, as well as the transmission. Why they are failing is excessive heat. That is just my guess. They know what it is. I can not afford a costly transmission bill that only finds me back in an unreliable vehicle with some serious safety issues.

21 Electrical System problem

Failure Date: 09/19/2016

Requesting a recall on the 2010 GMC Terrain. Mileage that was on the sticker was incorrect. Far from the truth. Major oil consumption, never seen anything like it. Tapping noise was reported @ 3,000 was told it was normal. Knew it was not. Had to replace camshaft, electrical problem, head lights constantly going, never lasting anytime. Will now have to replace transmission and probably engine. GMC stated they have no record of any problems with the Terrain they stated if there were any problems there would have been recalls and that the NHTSA would have done this. Will this be done? not sure how GMC is getting away with this. So many complaints on line. Are there any class action suits for the Terrain? can we start one? there are plenty of people with the exact same problem. Not even similar it's exact.

22 Electrical System problem

Failure Date: 05/03/2016

I purchased this vehicle last may 2015 with no warning indicators working my vehicle loss excessive oil and now needing a new engine, how does a vehicle lose 4. 5 quarts between a oil changes. Now I'm stuck with the cost of repairs for installing a new engine and the extended warranty and gm motors refused to help me with repairs. I have six children at home I provide for and now will be eating a new engine at the dinner table for the next four years! thanks a lot gm for not living up to your name im going to Toyota next vehicle. The good thing I was parked at a store when the vehicle gave out with no warning!!!!!!!.

26 Electrical System problem

Failure Date: 08/27/2015

Okay…the truck first started with the car alarm going off at anytime. We went to the dealership and said nothing was wrong. We took it home and nothing. Then the everything in the front board (radio screen, dashboard) was staying on when no one was in the car an off when someone drives it. We took it back to the dealership and and said something about the a timer. We bought warranty and it didn't cover it. Okay, I ask if it would be a problem to wait 2 weeks for I can have money to fix it later and they said yeah. A couple of days after. A family member drives the car on the freeway and the car just shuts down on her. We took it back to the dealership and now they are saying it's the camshaft. The warranty doesn't cover that either. Still being patient, I declined service because I had not enough money for the fix and find odd that is a different problem. Couple days after, the car won't turn on. It would only turn on when it feels like it. Long story short. Took it back to the dealership and now they are say is the battering. Got into an arguments talk to every supervisor because they don't know whats the problem but whatever it is is not covered by the warranty. Was able to get gm to pay something for repairs and paid only deductible. Car is fix from everything. Okay week, later the car is repeating the steps. Took the car immediately to the dealership and they are saying there's nothing wrong. I'm getting frustrated now, they are not checking the car and it gets worse when I bring it back.

We have a 2010 GMC Terrain and the hatch door opens on its own. It occurs while parked and while driving, happening several times a week and often several times a day. We have closed and locked the door/car with the button in the car, with the key and manually and it still occurs. The hatch latch has been replaced but the problem continues. Not only could something fall out of the back and cause an accident, it leaves us open to theft as well as being a nuisance and a worry.

Failure Date: 11/09/2013

I was going about 40 mph about to get on the freeway, when my car begin a loud noise, shaking, and dropped speed to about 20 mph. The dashboard said something also about no power, no matter how much I pushed the gas pedal, car would not accelarate. Instead of getting on freeway I pulled over to a gas station. I cut the car off and left off for a minute. I cut it back on and was running normal. I immediately went to the dealership where I was told there was a recall on the throttle body and they would replace for me. The problem is that no one bother to notify me, and if I had not had this problem might not had known.
