Owner report 11588928 · 2024-05-15 (May 15, 2024)
ON [XXX] my spouse was driving her new 2024 GMC Terrain in Asheville, NC. When suddenly the car stopped and when was able to maintain control and coast to a safe area. The vehicle was subsequently taken to the dealers service center GMC Asheville, NC (Harry's on the Hill). The diagnosis was determined to be a defective a transmission valve body. In discussion with the dealer service manager he indicated this is a common occurrence with the valve body. Needless to say this defect can be fatal especially during inclement weather, fast speeds, wi…

Owner report 11590680 · 2024-05-24 (May 24, 2024)
I was leaving work when my car had trouble accelerating from stop. The engine revved, but the gear would not engage. It happened several more times after I stopped at a light or slowed to get on the highway. It would take a minute or so to engage, and then I could drive the car, but it made it dangerous when trying to merge on to the highway or to make any turns in to traffic. It then happened two more times as I slowed to make turns until my engine light came on as I was turning on to my street. When I finally made it to my house and put it in…

Owner report 11588419 · 2024-05-13 (May 13, 2024)
When shopping for a new Vehicle I noticed this but purchased the vehicle anyway. I attempted to look under the hood of my new GMC Terrain. I have a (hopefully temporary) handicap from a medical procedure I have been dealing with for over a year. I found that the hood assist springs or air shocks have been eliminated from the 2024 model. I can lift the hood on my 2010 GMC Sierra, but I had to have my wife help me lift the hood on my 2024 Terrain. My guesstimate is the hood weighs 50 plus pounds! Once the hood is lifted you have to install a rod…

Owner report 11711615 · 2026-01-17 (January 17, 2026)
Powertrain System failure while driving, causing complete loss of power on road. The car lacks any accessible manual overrides to put in neutral or turn off parking break. This leaves the car stuck in park with all four wheels locked in the middle of the road in an incident with no safe way to move or tow the vehicle. When attempting to tow car must be dragged, and parking brake continuously engages. Tow attempt took nearly 3 hours to saddle the vehicle in the roadway. Vehicle currently awaiting formal inspection/repair from dealership.
