2015 GMC Terrain electrical system problems

“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?”

“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 crushing limbs or causing incapacitating harm. In a frightening moment, one of my family members narrowly avoided a potentially catastrophic injury as the gate threatened to strike her right hand. While I sustained a minor injury to my arm, a superficial wound, the gravity of the situation cannot be understated. This dangerous malfunction persists, rendering the trunk unusable out of fear for the safety of myself and my loved ones. Given the potential for life-altering injuries, I implore you to take immediate action and initiate a recall for all GMC Terrain 2015 models affected…”

“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.”

“Engine lost power suddenly while driving. No warning. Fuel pressure slowed to where vehicle no longer moved forward. Again. No warning. Timing chain slipped TWICE and destroyed engine without warning. “Engine power lost” appeared on dash from driving without warning or incident. Excessive oil consumption without warning. Smoking engine even though had regular oil changes. Engine had been inspected by dealership and allegedly had no issues. Car never smoked but did after second time of timing chain slipping/breaking. This issue has happened repeatedly to many drivers who own these vehicles. Had a difficult time stopping after engine and total power failure without warning.”

“Not really sure if it is electrical but the Stabilitrak light came on and the car jerked and I could not go over 50 mph and that would be fine however when you are on a freeway and the speed limit is much greater you could cause and accident. I took the vehicle to a garage and they put it on there computer and reset it and it seemed to work OK until I again went on the freeway and the same thing happened. Again I took it back to the same garage and they recommended I take it to a GMC Dealer which I did and they could not find the problem either after spending around $600.00. I did take it to the GMC Dealer which the vehicle make is a GMC.The problem, to the best of my knowledge, started about April 2023.”

“Never had issues on my vehicle I only have 42,000 miles when I brought my vehicle it only had 28,000 miles I had two recalls recently fixed 2/21/2023 a month later while driving my vehicle stopped and check engine light came on also there is a dinging sound whenever I get into my car which wasn’t there before I was in my parking lot parking my car when it shut off 3 times”
