    Windshield wipers quit working. I can hear something, but blades don't move. I see the 2014-15 have a recall.

    The timing chain is failing on my 2012 GMC Terrain. It’s dangerous to drive and it started without warning (to me). It’s my understanding that this is a common problem with this year and model GMC vehicle as many owners are complaining about the same issue. Will GMC be notified so they can remedy this situation? Many thanks.

    The display screen of GPS/Radio is blackout combined intermittent control button illuminating light went off( include emergency, A/C control), backup camera stopped working, turning signal lost click sound. Safety concern: 1. Emergency and A/C control buttons lost illuminating light(Causing night driving difficult.). 2. AC vent the temperature control lost visual status cause distraction of normal driving. 3. Lost Backup camera function which is supposed to be an assisted safety feature. 4. Lost turning signal click sound which leads to missing alert of turning signal malfunction. 5. Complete audio loss create unsafe for long trip driving. 6. GM doesn't provide genuine replacement part. This problem started from 2018 till now. I've contacted GM with no meaningful resolution. I visited the dealer and the only thing they could do is replace non guaranteed refurbished head unit with hefty price. I did some research online and found there are a lot of same problems happened to this vehicle and similar models of GM. After driving this vehicle for several years without incurring any accident, I realized that the losses of the some vital control functions and safety alert are actually very serious concerns and should be addressed and resolved by GM.

    When I stop at the light my car shake and rocks, then the car goes into limp mode. Where the stabilitrack comes on and the engine goes into reduced mode. And I can't go over 30mps. When this happened on the freeway is the most dangerous and scary feeling ever. I've got So many new parts and put over 3,000 into the car and it still has this issue. I've been do several different mechanics and nobody can figure out what's wrong. Gm needs to look into this, it's so many forums going on for this issue.

    Ball joint for wiper assembly just "pops off" while in use causing wipers to stop working. I have taken vehicle apart, fixed the issue ( reconnecting the ball joint) and issue happens again. I understand the vehicle is from 2012, but uses same part 2010-2017, which is currently a recall on 2013-2015 models. First occurrence of this issue was July 02, 2019. I brought to GMC dealer, they said they were out of the part. Since then I've not had the issue until today March 14, 2023 where I almost hit another car, due to it popping off and stopped working while in motion.

    As I was driving on December 24, 2022, (the temperature outside was 7 degrees).I heard my vehicle making a funny sound. I pulled over to a safe location then my truck cut off by itself. I got out of my truck and noticed that oil was on the back of the rear tire wall and on the ground. I had to get it towed to a repair shop. They told me a couple days later that the PCV valve was gone and that caused the rear main seal to go bad. Several days later, I happen to see a recall on YouTube about the PCV valve that GMC had issued back in March 2015, but I never received a letter through the mail. To get this fixed it’s gonna cause me a lot of money. Unless GMC is willing to pay for it.
