“I am submitting this complaint regarding the engine timing chain failure in my 2015 GMC Terrain because I believe it presents a serious safety hazard. Before the failure, the vehicle began experiencing intermittent symptoms, including engine jerking, shaking, rough operation, abnormal engine noises, and an intermittent check engine light. While driving on the highway, the engine timing chain failed, causing the vehicle to suddenly lose power. I was traveling at highway speed and had to safely maneuver the vehicle out of traffic.

“My vehicle began jerking, shaking and kept shutting off in a highway intersection. I looked on the ground after coasting into a gas station to find oil leaking from under my vehicle. I've never had an oil leak and it caused my starter to go and I've had to replace the camshaft sensors all within the same week. It appears the rear seal went after the cold streak we had. I need my vehicle to take my mother to treatments, etc. Is there any recalls on this?”
NHTSA complaint #11639654, 2025

“I am writing to urgently request a safety recall for the GMC Terrain 2015 due to a critical issue with the lift gate mechanism, which may be both electrical and mechanical. Recently, while utilizing the lift gate for routine activities such as grocery shopping, a terrifying incident occurred that endangered the safety of my family members. Upon opening, the lift gate exhibited a concerning behavior, forcefully closing without warning or control, posing a severe risk of injury. Despite attempts to intervene, the gate continued its downward motion unabated, presenting a serious hazard of crushi…”

Power Train 26

“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. T…”

“The timing belt on the GMC Terrains from 2013 to 2015, mostly 2015 are breaking at a unusual amount. If you google it , there is story after story about this problem and GMC has not done anything. This appears to be a problem with the Terrain and I want them to issue a recall before mine breaks. It is expensive to fix and it can also be a huge problem if it breaks when you are driving. Something has to be done as this is not a coincidence that this is occurring to a large amount of Terrains.”

“The radio dead out randomly. Which means the back up camera is non working. I wasn’t able to see a stump and hit it. Doesn’t seem safe. Like what would has happened if it was a person instead and they like the stump was in my blind spot while backing up. I feel like this is a safety issue. I have looked it up online and found out this is a common issue with these vehicles.”

“The rear hatch would open but then start to slowly drop. The local dealership diagnosed the problem and told me the pump needed to be replaced but quoted $1000. I chose not to have the repair done at that time but recently the hatch opened and then dropped suddenly hitting me on the head. There were earlier model recalls for this problem but not on the 2015. This is a potentially dangerous condition.”
