SERVICE BRAKES
Vehicle brakes went completely hard and vehicle would not stop. There was no warning signs, no lights on the dash and vehicle was driving on highway normally. Upon taking a highway exit, I could not stop the vehicle, completely unexpectedly. Upon further research it is a very common problem that needs to be addressed. My 3 kids and wife were in the vehicle when it happened, and this is actually the second time it has happened. The first time it happened we could not stop the vehicle at all to turn onto the road I live on, could barely push the brake pedal and coast to a stop. The repair last time it happened was the camshaft driven brake booster vacuum pump, and it has failed again after 20,000 miles. This is a serious manufacturer defect that has almost killed my family twice now.

ELECTRICAL SYSTEM
The door locks began to have issues; the locks started to work only occassionally for no apparent reason. I've been locked out of the car several times and had to use the auxiliary key. Plus I couldn't lock the car while I was inside as the interior door lock button wouldn't lock or unlock the doors either. It's not a kefob or battery issue and no lights on the dashboard. The dealer reports that they couldn't reproduce the issue. However they found corrision on the electrical harness inside the passenger front door. I replaced an electrical harness in the rear bumper 18 months prior for corrision found. The dealer says they received a service bulletin on the "electrical harness" issue however the dealer won't cover the cost of $500 to replace the harness. As this deals with the electrical system, my concern is that it may effect the operation of other components of the car while it's running. Safety and security is of the utmost importance whether at home or away as it regards to being able to lock or unlock the doors.

ENGINE
I purchased this Vehicle in February of 2023, I had a problem shortly after with the oil always being low. I was adding oil to it all the time. 7 months later the engine blew. This is a very faulty problem with this engine that I am NOW finding out. This problem needs to be addressed and fixed. Now I am stuck with a vehicle that I still owe money on that will cost me 6 to 9 thousand to replace the engine.

POWER TRAIN
There have been problems with the 2015 GMC Terrains Timing chain. The timing chain will break when the vehicle is being operated which causes the driver to lose complete control of the SUV, additionally, the engine will be destroyed. The bigger issue is the loss of control when you are driving - especially at highway speeds. GMC had hundreds of complaints but refused to issue a recall. A recall was issued but for only certain batches of VINs. I contacted GMC corporate service to inquire about what they are doing for the other owners who are experiencing the symptoms before the chain breaks. The representative told me they were only recalling certain VINS, I explained that it was not a fluke that my car was experiencing the same issues as the recalled ones. The response was they weren't recalling my VIN. I inquired why there were only some, not all, and she said it depends on what time of day the car was assembled the weather, and the place. Just bizarre this answer, my vehicle is the exact vehicle model that is being recalled and is experiencing the same problem - it makes no sense. So if I am driving on the highway or any road USA and my chain breaks I may kill myself as well as others. Then there is the cost to repair this defective part, by recalling certain VINs they are acknowledging there is a defect that they are responsible for. I want my vehicle repaired at the expense of GMC as they are the cause of the issue. I don't want to die or kill anyone. Can you please help me and many other owners who are dismayed and just confused and angry? My car is now stalling out while I am driving, or moving at all.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, POWER TRAIN
The blower fan for heat In my vehicle was replaced in October 2022, recently the Defroster will not engage and it is vital to winter driving. The mechanism that switches between which vent to blow out air was replaced and the Defroster will still not engage, rather it comes out of the heat and face vents. Shortly after the Defroster stopped engaging, the rpms will start fluctuating from 2 suddenly up to 6-8 without warning or acceleration then go back down and back up as if it's chugging along. Even when applying the brakes, this will continue to happen and there's concern for Rear-ending or crashing when this happens. When driving home 2 nights ago the county police pulled my vehicle over due to burnt out headlight, which was replaced less than 6 months ago. Took the car in to get bulb replaced today and multiple bulbs later, the light is not fixed and it was said to be electrical and need to go to another shop. Beginning to wonder if this is all a bigger problem about to happen with engine/ powertrain.. with commute to work in the dark and electrical problem in the headlight randomly and the acceleration issues there is definitely a concern for safety.

UNKNOWN OR OTHER
This complaint is for the rear camera / back up camera system: After purchasing the vehicle the back up camera started to get hazy around 25,000 miles. At 35,000 miles it was completely useless. I purchased a second back up camera and had the body shop install it. It has now been right at the same mileage, 30,000 miles, and the camera is again hazy. This is not an external haze where I can just wipe the camera off, even carefully so as to not scratch the lens or cover, but a haze that is behind (inside) the protective outer lens (cap). This has happened with both cameras and I am facing installing a third. My vehicle has less than 70,000 miles on it! I've had other vehicles where the camera lasted way longer (lifetime!) of the vehicle. When I went to the dealer with the complaint on the original equipment they said it was because the lens was scratched, but didn't look any further that the lens was foggy 'inside'. The safety of myself and others comes into play when I cannot see what is behind me: trees, curbs, vehicles, people, drop-offs. Also, at night when in reverse the dash area the feed goes to is so bright that it blinds the driver and the system is unable to be dimmed to allow proper viewing.

VISIBILITY/WIPER
My wife was driving on the highway to work when it was raining. Both of the wipers stopped working all of a sudden causing her to not be able to see out of the windshield. When she got home that night I could see that the linkage arm had came off the ball joint.

STRUCTURE:BODY:HATCHBACK/LIFTGATE
The latch for the rear hatch/door does not release every time. There have been instances when itmes have been in the cargo area and when the button is pressed, it will not release the latch. This causes someone to have to crawl over the back seat to retrieve the items from the cargo area. This also is causing my son to have to store items, that would normally be in the crgo area, on his back seat. I owned a 2015 terrain and had this same issue. The latch was replaced but still did not operate correctly.
