Failure Date: 01/31/2021

I was driving about 2 months ago when the low oil pressure light went on on my dashboard and it said stop engine now with a very loud alarm. I pulled into a gas station to check the oil and I did have to add about 3 quarts of oil. So I assumed this would fix the issue but when I started driving about 1 minute after I started driving again the low oil pressure light and alarm came and it again said stop engine now. I finally got it home and I turned the car off and then tried to restart the car and it did not start. I had it looked at by a few mechanics and they said the engine was gone that it failed the compression test 3 time and the vavles were bent . I had just got a oil change about 1 month prior to this .

40 Engine And Engine Cooling problem

Failure Date: 11/01/2020

We received a notice in the mail regarding our vehicle with our VIN #. And it mentioned our particular size engine had a recall for potential emissions part condition of degraded catalytic converter and/or oxygen sensors caused by excessive engine oil consumption affecting some vehicle from our year, make, and model. We were surprised to receive this notice because we always park in reverse and we had noticed how it was turning the curb side black coming from the tail pipe. We did receive one other notice before and took it to the dealership to have it maintenance but my honest opinion I do believe they did anything to our vehicle because it was running the same and also took it to midas after taking it to the dealership because it ran the same. Anyhow I hope upon receiving this other notice we can actually maybe get reimbursed and actually get it fixed finally.

45 Engine And Engine Cooling problem

Failure Date: 12/15/2019

Complete motor failure, engine oil loose, complete loose of control. While driving down the highway, this vehicle had a sudden oil loose, no warning lights came on causing my spouse to loose all control of the vehicle nearly incurring a head on collision on a local highway at speed of 60mph. We had to have to vehicle towed to a local shop and is no longer drivable and the motor is ruined. The vehicle only has 83,000 miles and all evidence of motor failure appears to be on the manufactures behalf, as the motor over pressurized and lost all oil and didn't have a safety warning, this could have killed my spouse or others. I have attached photos for review.

50 Engine And Engine Cooling problem

Failure Date: 06/08/2019

In June 9, 2019 my engine light came on in park in my driveway. June 10, 2019 I took my Terrain in for service and to have the engine light looked at cavender west in san antonio, TX. Where I purchased the vehicle in December 31,2018. Cavender called to inform us that the timing chain was bad. I did some research because a vehicle with 60,000 miles on it shouldn't have a bad timing chain, I wouldn't think. I have called both cavender and gm with no help. I have read numerous complaints for the same issue. I had filed a case with gm about this know problem that still continues. Gm is very well aware of the problem. I think this timing chain nightmare should be recalled.

54 Engine And Engine Cooling problem

Failure Date: 01/30/2019

Rear main seal blown due to condensation freezing in such cold temperatures. This happened on my 10 minute drive home from work. Engine was shut off and hasn't been restarted. Mechanic stated there were at least 4 other vehicles this week with the same issue, within two shops. A recall on certain vehicles was issued, but not mine. I would like this to at least be investigated to possibly expand this recall. Car will not get fixed until at least Tuesday, as they are short on the bolt kit due to high demand. Thank you.

56 Engine And Engine Cooling problem

Failure Date: 09/13/2018

I parked my vehicle in the driveway. Upon exiting the vehicle I used the key fob to lock the vehicle, it beeped and began to walk away. As I was about 10 steps from the vehicle, it beeped again as if I hit the fob and restarted itself. It literally restarted itself. They keys were not in the ignition, they were in my hand. I was unable to unlock the vehicle using the key fob and had to manually open the door using the actual key in the door lock. I was unable to turn the vehicle off by reinserting the key in the ignition. I wiggled the shifter and the car turned off. This is the fourth the car has been running while the keys were not in the ignition and it is the second time the vehicle restarted itself without the key being in the ignition. This is clearly a manufacturing issue. What are you waiting for to add this vehicle to the recall list? property damage and personal injury will eventually occur and then I will sue GMC for damages. I am officially putting GMC on notice. Please recall this vehicle and fix this issue.

As I closed the door and used the key fob to lock the vehicle, it restarted itself.

Please add this particular vehicle to the recall call list for this issue prior to personal injury or damages occurring.
