- #11606707August 6, 2024VISIBILITY/WIPER, FORWARD COLLISION AVOIDANCE: WARNINGS
The headliner fabric detached somehow from the panoramic track causing the fabric to hang down obstructing the rear and back window view causing a safety hazard. The automatic forward collision alert will come on for no reason since this has happened. The problem has not been reported to insurance or the manufacturer yet but GM is my next call. This is a safety hazard due to the obstruction of visibility to safely make turns or change lanes. This happened August 5th while driving with the windows up. It just dropped down still attached to the front of the track and the rear.

I was driving my suv while it was raining heavily and my driver side wipers just stop working out of no where the passenger side still operates. I have not been to see if a dealer can fix it because I was unaware it was under recall so now I’m trying to find someone to fix it while under the recall.

- #11606036August 2, 2024POWER TRAIN, SUSPENSION
My transmission keeps sticking when I shift into drive or reverse. Just a couple of days ago, it happened the worst it has ever done before. I shifted into reverse and my vehicle was completely stopped when I shifted. I began to let off of the brakes and gently push the accelerator to start moving back, my vehicle then punched itself into reverse. I felt after that incident, something had to have been damaged. I’m almost afraid to drive my vehicle after that. When my vehicle punched itself into reverse, I was literally jolted towards the steering wheel and thankfully my seatbelt caught me. Incidents with the the shifting into drive or reverse have happened before, but never nearly as intense. About a year ago, I brought my vehicle in to my local GMC Dealership for a concern with my transmission shifting weirdly and holding itself in gear at an unnecessarily high RPM speed. The technician stated to me, “with these 9-speeds, they tend to get confused at various speeds”. I asked him to elaborate and he could not. These issues have now gotten worse. With my suspension, every turn I take, I get a kreaking sound from my front driver side wheel well. It sounds as if my tire if going to break off. I’ve done visual inspections and nothing out of the ordinary is noticeable to the eye. My vehicle is a 2019 with less than 40,000 miles on it. I should not be having all of these issues. I’m genuinely concerned for my safety.

The vacuum pump gears for the brake assist was shattered and metal parts were sent into the engine. I lost power brakes and was lucky to be able to stop the suv. The car was towed to a GMC dealer where it was diagnosed with a damaged exhaust cam, a shattered vacuum pump and metal pieces in the motor. Cost to fix $3200. This is a 2018 GMC Terrain with 112000 miles on it. I had a powertrane plus warrenty that was still valid but they refused to pay for anything. They claimed the vacuum pump caused the problem and it was not the engines fault. There were no warning check engine lights before this happened.

As I was driving, brakes became very hard to press. I was barely able to slow down to bring the car to a complete stop. Brakes became very stiff and required a ton of force to come to a complete stop. This came with no warning signs or alerts from vehicle. It was only after this occurred that the Service Break Assist light came on.

Was driving along and transmission downshifted (?) wouldn't change gears. Tachometer was like a race car. Just went wild. Limped it along to a dealership. They informed us it was probably the transmission. It was determined it was indeed the transmission. They also stated that they had 7 more waiting in the service area waiting for parts to repair. Ours was to be #8. We called the dealer we bought it from, they sent a tow truck and towed it to their service area. Luckily, I wasn't out on the interstate going 70 mph as I would have been in just a few more minutes. Very scary situation as I was in 3 lanes of traffic. It was in town, so traffic wasn't moving fast. I was 2 hours into my vacation. Needless to say, that put a damper on things. Had to rent a vehicle, unpack my vehicle and repack the rental. Oh, and by the was it is a 2024 Terrain with ONLY 2400 miles!
