Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Two incident warnings on my dashboard saying of my back hatch was open when it was not. Had it serviced because the dash warning would not shut off. Service said it was fixed then happened again. Twice this happened intermittently. Another incident when on navigation screen, when the navigator gave directions it changed to phone screen and went back to navigation screen when she stopped talking, like she was calling me to verbally give me directions! …”
NHTSA complaint #11348999, filed 2020-08, 13,000 miles“Lift gate on this vehicle opens to a height of 69 inches . At 74 inches I am constantly banging my head on the lift gate. My 2017 model opened to at least 76 inches which is more reasonable. I consider this a safety issue, as this is a flaw in the design of the vehicle. The model that has a power lift gate opens to around 76 inches.. A full 7 inches higher than the manual one.. The dealership never pointed out this problem to me seeing that I am 74 inches tall.”
NHTSA complaint #11163864, filed 2018-12, 25 miles“I purchased my 2019 Terrain denali on 2/27/19. I began my drive into work this morning (3/4/19) and merged onto the freeway and seconds later heard a loud explosive sound, only to realize the first half of my panoramic moonroof was shattered (see inside photo). Shards of glass were falling into the vehicle but it had not collapsed completely at this point. I did not drive under anything that may have fallen, there were no objects in the road that came up to hit my vehicle, the glass just shattered out of nowhere. …”
NHTSA complaint #11184155, filed 2019-03, 60 miles“The backup camera in our 2019 GMC Terrain stopped working one day - has blue screen and says Service Rear Vision System - so we’ve been driving a year with no backup camera. The dealership wants almost $1000 to fix this issue. And this issue seems to be very common in 2018-2020 Terrains. We bought the vehicle in December 2023”
NHTSA complaint #11722084, filed 2026-03“My 2019 GMC Terrain has a faulty back up camera system. It shows a blue screen that says Service rear view camera system, This has been a faulty system for years until it finally stopped working completely. I have researched the issue and have discovered this is a known problem. There was a Service Bulletin 19-NA-076 dated April of 2019. Why has there not been a recall for this safety issue?”
