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.

The rear tailgate on a 2012 GMC Terrain has auto lift and close. The tailgate opens, but wont stay open then closes hitting you in the head. The heavy tailgate comes down hitting you in the head, and it takes a lot to hold the gate up. I called the dealer who said it could be the power lift. He said there was a previous recall to fix the same issue, but that part is not holding. I spoke with the dealer and found issued on line. No warning lamps or messages appeared.

VISIBILITY/WIPER
Driving in heavy rain south on the I-5 at 545p. In peak traffic and wipers suddenly just stopped while going 60mph in the carpool lane. As we past the exit for I-405 There was no shoulder to pull off of on my left. I had to cross over 5 lanes until I could safely get off the freeway. Then drive another 5 miles on side streets getting out an manually moving the wipers every few blocks so i could see. I'm female and over 50 yrs old. There was not a place I felt safe to just pull over at night. I stopped at a friend's. I can hear the motor moving but the wipers are not. I do not recall ever seeing the recall on the ball bearings and nor the wiper linkage but found one. However I'm have 72k miles and have owned it for 10 yrs.6 months. So it may not be covered, which I believe is not fair. I almost died and could have caused other deaths just trying to safely maneuver off the freeway, which I felt was safer than sitting on the side of a very dangerous section of the freeway. I know people with cars over 40 yr old that were left outside with over 200k miles and the wipers have never just died. I am the original owner and my car has been garaged for over 95% of the time when not in use. I will call the dealership in the morning but trying to get ahead of this since articles are saying there are no parts. Scared and frustrated.

First off before I got the car it had gone through a tune up. About a couple months after I got the car little things started to happen it would rock back and forth while idling I thought it was kind of an indicator that it needed oil but the percentage was still at a decent range and telling me it didn't need oil plus I hadent driven it 3000-5000 miles. Then engine light came on had it inspected codes ran came back telling me something about Throttle body So I purchased a whole new throttle body in Prosser at dealership costing me some booko buks and swapped it out when I got back home I then took it for test drive along with my 4 kids in the vehicle with me and then a little ways about 20 mins driving engine power reduced light came on along with stabilitrak and eventually lost power I was stranded in the middle of summer in the middle of nowhere with my kids windows rolled down ppl drove by and asked if I needed help and eventually came back with jumper cables tried to jump me but the car wouldn't budge I then left the car there overnight and took battery out to have it inspected the next day IT WAS FRIED (over 4 yrs old) so I had to purchase a new one costing me roughly 150 buks then took it back to where my car was stranded put it in and alarm went off and I clicked the button on key ring stuck it in ignition shit the door behind me locking keys in car while vehicle was still running and had to bust a window out to get to em. Got into car drove off made it back to my apt left it running outside while I went inside to get some stuff before I THOUGHT the problem was solved it shut off again.....I then had to replace the alternator costing me another pretty penny....about a couple weeks later I was starting a new job at a assisted living facility and arrived 10 mins early shit car off a noticed smoke coming from under hood I was confused because where the smoke was coming from couldn't have been it overheating I popped the hood and my car was on fire!!!!

I still have more to add to my other complaint. The fire started with alternator apparently there were crossed wires took alternator back to Orielys where I got it warrented out fixed the expanded wiring and replaced a hose and other things damaged by the little fire. Then after that things kept getting worse. Then it was spark plugs that were rusted that I replaced eventually I complained back to the dealership I got the car from and they agreed to help repair it after a posting by me on fb that I wasent a happy customer basically and that I literally had a sitting duck. Turns out the timing chain needed to be replaced and other little things. I've replaced O2 sensors camshaft sensors gaskets in catalytic converter had it inspected thinking it was a clogged exhaust the excessive oil usage was insane I would be going through 5quarts twice a month! I'm just tryna have a DECENT WORKING VEHICLE for my kids and I. I literally can't keep a job because I DONT HAVE RELIABLE transportation....I've put sooooo much money into this vehicle and now I might have a blown gasket!!! And that's because I haven't even been driving the vehicle. I got the car on Jan 7th 2021 with 129,043 miles on it as of today it has a total of 164,627 miles on it meaning in between the two years that I've owned the vehicle I have only put a total of 35,584 miles on it.....for it to have this many problems for so little mileage is INSANE!!! my kids were in the car with me today when the car started smoking like crazy from under hood and exhaust I pulled over turned the car off and took my baby off car seat in all and got away from vehicle thinking it was on fire again. I popped the hood and notice it was coming from under manifold.....meaning its probly a blown gasket after I just replaced the camshaft sensor AGAIN......it's ridiculous all the stuff thats going wrong with this vehicle with so little mileage that's been put on it.

SERVICE BRAKES, ELECTRICAL SYSTEM, ENGINE
The check emissions light for the engine light came up on the dashboard. Without prior warning or other signs the vehicle lost engine power in the middle of the road. The entire electrical power and engine stopped working and the brakes jammed. This causes the vehicle to become unstoppable in the middle of the road causing a safety hazard to the vehicle, driver, passengers and fellow vehicles on the road. The only way to stop the vehicle is somehow use the gears to shift to parking position, turn the engine again on and try to remove the vehicle from the middle of the road.

very serious failure ... traveling at night, in a rainstorm, doing 70mph on a highway and the wiper regulator connecting the wiper arms to the wiper motor fails ... no warning what so ever ... no intermittent operation or noises, nothing ... looking into this problem I see that GM has issued a safety recall for 2014 and up versions of this vehicle but not my specific model year ... what are the chances that the hardware used in my particular vehicle model year are any different than those listed in (22V-165) this safety recall.

Vehicle stalling like the hundreds of other complaints I’ve seen that almost caused an accident when vehicle suddenly stops. Dealership only offered to do diagnostic at my cost with no guarantee they will find the problem. Nothing is registered on the vehicle computer and no check engine light.
