ELECTRICAL SYSTEM, POWER TRAIN, STRUCTURE:BODY
After heavy rain the backseat of the car was flooded as well as the rear wheel well likely due to the sunroof not draining properly. This led to electrical failure of the sunroof mechanism and potential to damage other electrical elements. This will be looked at by the dealership but have read that this is a known issue.

SERVICE BRAKES, POWER TRAIN, ELECTRICAL SYSTEM
There are 3 recalls and one open on this car I was sold by a dealership, none of them ever fixed. I drive to work in the highway the car never had any warning light on but the RPMS would occasionally go up for no reason. I told the dealership the second day that it had issues , they took it and say they fixed the back brakes but did nothing about the engine or transmission whatsoever ever. This was the beginning of may and it was in the shop two weeks. I called my lender to even get out of the loan and a saleswoman even tried assisting me into talking her manager out of the loan because of all the issues. Fast foreword to august I had just gotten a new job and was driving in the night after hearing that ticking or slight knocking noise and I went to my job and as i tried to park the brakes went completely stiff on me! I could not get the car to slow down I had to weave through other cars and people in till it finally coasted to a stop. So I put it in park and immediately after the check engine light came on. I tried to start it and it would start , putter and turn off over and over. I had to end up calling OnStar to have a diagnosis which she said something like solenoid and something being clogged. So it was towed to my residence and before i could get it towed to s shop they lender came and repossessed it because I had missed payments due to losing my job unexpectedly, completely unexpectedly. I told the lender of the problem and the unfortunate troubles I was having to pay for the car but I had just landed a job and could start payment but she didn’t care. She said she is going to tow it . I had my friends dad who is a licensed mechanic look at it before it was towed and he said the car was trash , basically a lemon that there was oil clogged and instead of passing through like it’s supposed to do it being pushed the opposite way and ending up in other reservoirs it shouldn’t be in. I obviously didn’t do that type of damage oil and trans problems I was scammed

ENGINE
Vehicle shut down and turned off while being operated. No warning lights were on at any point before the incident. I was driving down the road and without warning, it just turned off. My safety as well as the safety of the drivers on the road around me were compromised by this sudden failure as the vehicle was in motion when the incident occurred and I was unable to properly operate the vehicle. When I tried to re-start the vehicle the engine would not turn over and several warning lights were suddenly on. Vehicle was towed to dealership and the service department said the timing chain jumped and the engine needs to be replaced. Multiple complaints have been made against GM for the faulty 2.4L Ecoboost Engine that causes excessive oil consumption with no appropriate monitoring or warning system in place leading to timing chain issues/failure that destroys the engine without warning, often while the vehicle is being operated. No recall has been made and no warning is given to customers who purchase vehicles with these engines. I have owned this vehicle less than a year and the repair invoice I was given quotes over $10,000.

FUEL/PROPULSION SYSTEM, ENGINE, VEHICLE SPEED CONTROL
My vehicle begin stalling when accelerating (mostly after stopping) June 2023. My vehicle has almost cause me to have two accidents because it intermittently stalls when I try to cross an intersection. This is my fourth time taking my vehicle to the GMC dealership, and they tell me they can't find anything wrong if there is not a code. I have reached out to Corp, and I'm waiting to see if they can help get to the bottom of my problem. My car has been sitting at the dealership since June 30th 2023....I call the dealership periodically, and they never reach out to let me know what's going on. I am afraid to drive my vehicle at this time because next time another car may not be able stop and give me time to get across the road. I'm filing this complaint because I seriously think someone is gonna get killed.. Thank you

FUEL/PROPULSION SYSTEM
My Terrain just started stalling. And it happens a few times a day. This is not safe. I had my daughters with me in their car seats, as I pulled out from a stop sign it just died. I couldnt steer or anything. People coming down the road and I am stuck In the middle of a street until I could put it in park and restart. And then it happens again when in reverse. I thought I accidentally had it in neutral. I restarted it and thought it was fine. It gave a little chugging when I hit the gas pedal but all was fine until I stopped to pull into a parking spot and tried to reverse again to straighten my car. I turned it back on, then it was good enough to get out. when I went back to my car it stalled like 4 times when trying to simply leave the parking lot.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Automatic Emergency brakes have unnecessarily or prematurely activated on 2 separate occasions causing my car to stop very abruptly which has resulted in Neck, Shoulder and back pain. I have been very lucky in the recent past and today that a vehicle was not directly behind me. The seat vibrated first when it sensed the car ahead was breaking. When I started to break, the emergency break kicked in. I did not report this the first time because I thought the car was doing what it was supposed to do. Today was unnecessary. No accident and no police report. I do plan on telling the dealership.

ENGINE, POWER TRAIN, ELECTRICAL SYSTEM
2020 GMC Terrain SLE Elevation Package 83,000 miles and needs complete engine rebuild @ cost of $10,700 per Dealership Service. Was told “I drove the vehicle with low oil” which Inturn is the cause of needing engine rebuilt. I have had this vehicle serviced, oil changed regularly etc NOT ONE TIME has the oil pressure/low engine oil nor anything related to oil illuminated on my dash. CEL yes after it apparently was too late and damage was done which showed code P06DD And P0324 through OnStar Diagnostics. There are also other complaints with same issue, and no notification of oil /oil pressure issues with relatively low mileage that have led to engine rebuild. I still owe on this vehicle through GM Financial, and a $10,200 engine rebuild on top of that… Not what I would expect out of GMC~

ENGINE
The engine burned a usually large amount of oil without warning the driver, resulting in engine failure. With minimal local driving and no warning, the engine was completely out of oil, resulting in an engine banging/rattling that began, resulting in total car failure. Like others with the same issue, a certified dealer diagnosed that a new engine was needed at a cost of $9500. An independent repair shop also confirmed a new engine would be needed.
