ENGINE, FUEL/PROPULSION SYSTEM
My car wouldn’t start, later found out it was due to timing chain issue which ended up blowing up my engine. I live 40 minutes from work and am consistently driving on the interstate for at least an hour a day. GM said there’s nothing they can do even though there’s been class action lawsuits for the engine. My car has also had oil consumption problems. I bought my car in March of 2022. The engine blew up by November 2022. I barely got my car back in September 2023. After the engine replacement, still wouldn’t turn on, over heated immediately when I did get it back. After paying $7440 for the engine replacement I had to fork over snother $650 to replace the fuel pump control module, and an engine control unit. My car overheated AGAIN just 2 weeks ago!!!!

ENGINE
This is a 2016 GMC all wheel Terrain. Over the past several years when accelerating the car would shake violently, because we could not reenact dealership could not diagnose the problem ,however as the issue has gotten worse we have been able to recreate and diagnose AND we are looking at a $2,000 repair based on a known ISSUE which DID NOT lead to a recall. The ACTUAL ENGINE IN ITS ENTIRETY SHAKES VIOLENTLY when accelerating!! How in the hell is this possible that these cars are allowed on the street without a recall. You should be ashamed!

VEHICLE SPEED CONTROL, POWER TRAIN
On October 13, 2023, I was driving on the highway when my 2014 GMC Terrain power was reduced. Suddenly, the engine light came on and car began throttling. Second, an error message appeared on my dashboard indicating “ engine power is reduced.” Then it stopped in the middle of the highway. I was able to restart my vehicle and drove it to a nearby mechanic shop. The mechanic said the problem was my timing chain and that my vehicle was not drivable. I left my vehicle at the mechanic shop because it was the weekend and It needed it to be towed to the dealership. On Monday, October 16, 2023, I had my vehicle towed to Buick Classic Service Center. After waiting for two days, I received a call from the service center stating that my 2014 GMC Terrain timing chain and pressure gas pump was the cause of the problem - with my vehicle. After, reading other owners similar complaints ; why is there not a recall to address this problem? Now, I am stuck without a vehicle and the company has no idea how long it will take to get the parts needed to fix my vehicle. I was told that the timing chain and a tension is on back order due to the employees of GMC being are on strike.

ENGINE, LANE DEPARTURE: BLIND SPOT DETECTION
The engine - My engine blew because oil evaporated out of the #1 cyclinder, which drained the oil. No warning lights went on and the vehicle stalled in the middle of rush hour traffic. The dealership told me it was because of a factory defect, but no recall on that part of the vehicle. This could have been much worse if the vehicles behind me were going faster than they were and not able to stop before rear ending me. Because this was a factory defect it should have been recalled and I should have been notified of this problem when I bought the vehicle.

UNKNOWN OR OTHER, VEHICLE SPEED CONTROL, ENGINE
On 4/10/2023, I took my vehicle to a local GMC dealership because it was stalling and didn't have any power. Upon accelerating the vehicle it would stall and take off at a high speed. The dealership has had my vehicle periodically from April 2023 and it presently sets at the dealership because they ain't getting a code, But after the dealership drove the truck for over 200 miles, they were finally able to duplicate the stalling yet are not able to diagnose the problem!! This vehicle is very dangerous to be on the road and I have almost gotten hit twice and I'm not driving the vehicle anymore at this time. I have previously reached out to you all and I would be most thankful if you could get in touch with me. Thank you

ENGINE
Vehicle stalled, steering column was shaking. Fortunately, this took place when leaving work parking lot. Had it happened on the road, driver and passenger safety would've been at greater risk. In addition, this particular issue could've resulted in a fire in the engine compartment. Took to mechanics and was informed that cylinder #3 was no longer contributing to engine function. Technician discovered cylinder was leaking from exhaust valves. Vehicle has not been inspected by the other individuals. Prior to this incident, vehicle was consuming oil at an enhanced pace although the oil light indicator would never turn on. Engine light didn't appear until cylinder #3 failed. It's important to note there is a previous (successful) class action lawsuit for the 2010-2013 models for the same exact reasons noted above. Missouri is in the process of filing a lawsuit for the 2014-2017 models.

ELECTRICAL SYSTEM
Driving down the road at 40mph when the car shifts to park, the brake and steering wheel lock up and the car won’t accelerate. I had to pull over because I almost crashed due to the abrupt shift. Once pulled over I tried to restart the car but once off and back on it wouldn’t allow me to shift or drive it. The steering wheel and brake remained locked. It has happened several times over the past week.

UNKNOWN OR OTHER
The problem with this car that continues is that when driving over 65 miles per hour/ more or less, the driver side door rattles and shakes. It rattle and it looks like if the door wants to detach. It only happens on the driver side, not the passenger side. I put my arm on the arm rest, and my arm shakes and that is not ok. I am concern and want to know what can be done about it. I do not feel comfortable driving when this happens and its a new car, it should not have this problem. The problem started right after I purchased the car and I already took it to service it and they said it was the tires not having enough air, but that's not the case, cause it still doing it. I need to take it to service it again Please advise what can be done about it and if they can find what the problem can be. Your assistance is very much appreciated. Thank you.
