Everything below is an owner-reported complaint submitted to NHTSA about the 2016 GMC Terrain, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
Windshield wiper mechanism broke while driving in heavy heavy rain near [XXX] . Extremely dangerous situation and almost resulted in a crash but I was able to make my way off of the interstate safely. Huge inconvenience because we had to wait out the rain! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
During heavy rainfall in the mountains at dawn, my windshield wipers suddenly have stopped working. We can manually move the wipers with ease and can hear the motor engaging but both front wipers suddenly stopped. We were 1200 miles from home on what was supposed to be a vacation. Carvana reports 2 recalls for my reports but the dealerships have no recalls for my year of vehicle.
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
My 2016 GMC Terrain 2.4L Ecotec first stalled while idling at a red light in Raleigh, NC. I restarted it and it sounded different, so I drove it home. The next morning it would not start. The failure occurred at approximately 69,939 miles with no meaningful warning. The dealer’s diagnostic report states there were no current relevant codes and no relevant codes in history. The dealer documented major timing-system failure: timing chain tensioner failure, timing chain guide failure, a timing chain guide bolt pulled out of the cylinder head, aluminum contamination in the cylinder head/oiling system, and engine replacement recommended. The vehicle was found unsafe to operate. This vehicle regularly transported my family, including my children. If the stall/no-start failure had occurred at highway speed, while merging, or in heavier traffic, it could have created a serious crash risk. The oil was maintained outside the dealership network and had been serviced before failure. I also topped off the oil shortly before this occurred. The 2.4L Ecotec engine family is known for oil-consumption issues, yet this vehicle gave me no direct warning that oil consumption had reached a dangerous level. A reasonable owner would not know to check oil every day when there were no relevant stored warning codes. Other NHTSA complaints involving 2016 GMC Terrain vehicles describe similar patterns: oil consumption, no warning lights, sudden stalling or no-start conditions, timing-chain failure, and engine replacement recommendations. I am filing because this appears to be an ongoing safety risk involving oil consumption without adequate warning, timing-chain/timing-guide failure, internal contamination, and sudden engine failure. I request NHTSA review this issue for investigation or recall expansion before this failure mode causes a preventable serious crash, injury, or fatality. The vehicle was inspected by a GMC dealer and remains unrepaired.
My vehicle started turning off suddenly when stopped and then when starting to move. I replaced my rear seal. A week later, I have oil in my timing and my engine no longer works. I have had it checked by a shop. No warning was given. I have my oil checked regularly and changed on time. I had a car full of people, adults and children, in rush hour traffic. The car is sitting in my driveway as I will need to negotiate with the lender on money owed. I am currently without a safe vehicle to drive, and I need that as I am a caregiver and home aid.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.

On or around August 15th I was in traffic and my 2016 GMC TERRAIN just shut off in the middle off traffic almost causing the car behind me to hit me is the rear. I got it started and then slowed down for a car that was turning in frount of me and it shut off again almost causing another car to rear end me. There where no warning light no warning at all just shut off I called a flat bed and it was taken to Clintscales Chevrolet in Belton Sc. They have informed me that it is a problem with the timing chain causing me to need a new motor. I have done research and it shows Gm has had problems with this problem in numerous engines in this year. This is so dangerous it puts life's in danger by shutting of in traffic with no warning at all.

Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
My steering wheel locked while driving. This has prevented me from turning the wheel AT ALL (100% completely locks while the car is in motion). The locked steering wheel lasts approximately 15 seconds. This has happened multiple times over a few month period. I took it to GMC who couldn't replicate the issue and said that GMC no longer makes the steering column assembly component, which they aren't sure would fix the issue, so there was nothing they could advise be done other than sell the car or spend a lot of money on diagnostic fees, which they said they wouldn't do if it were them. My safety and those around me were put at risk because I lost steering function while the car was in motion. The only option was to break and stop the vehicle. There were no warning lights or other indicators to alert of an issue.
Power steering failure and don't walk anymore, had to push my GMC Terrain. The light came on that says POWER STEERING FAILED. Contact service. It can't go any further.
