2017 GMC TERRAIN Complaints

Rear oil seal failed resulting in engine oil pressure loss and vehicle was stopped in middle of roadway

It's a known problem with gmc with a lawsuit for the PVC pipes clogging and blowing the main rear oil seal causing the vehicle to quit running

I just had an oil change in late December of 2023. As I was driving to work on [XXX]. My engine locked up. There were no warning lights. By the time I was able to pull over, a rod had gone thru the engine. Apparently there was an oil leak but no warning lights. This has not only caused me to have to purchase a new engine but could have resulted in a collision while driving. After doing some research this is a known defect by GM and a class action lawsuit. GM has failed to recall these vehicles for a known defect. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I purchased this Vehicle in February of 2023, I had a problem shortly after with the oil always being low. I was adding oil to it all the time. 7 months later the engine blew. This is a very faulty problem with this engine that I am NOW finding out. This problem needs to be addressed and fixed. Now I am stuck with a vehicle that I still owe money on that will cost me 6 to 9 thousand to replace the engine.

The contact owns a 2017 GMC Terrain. The contact stated while driving approximately 65 MPH, the vehicle started losing motive power. The contact was able to pull to the side of the road, and the vehicle stalled. There was no warning light illuminated. The vehicle failed to restart after several attempts. The vehicle was towed to an independent mechanic, who diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle was repaired; however, the contact stated that the vehicle was experiencing an abnormal oil consumption after the engine replacement. The contact stated that there was no evidence of an oil leak. The manufacturer was not notified of the failure. The failure mileage was approximately 130,000.

The latch for the rear hatch/door does not release every time. There have been instances when itmes have been in the cargo area and when the button is pressed, it will not release the latch. This causes someone to have to crawl over the back seat to retrieve the items from the cargo area. This also is causing my son to have to store items, that would normally be in the crgo area, on his back seat. I owned a 2015 terrain and had this same issue. The latch was replaced but still did not operate correctly.

1. The car started making a noise then started surging and jerking. I'm not a mechanic, so I don't know what happened but it will not crank now. Yes, someone can come inspect the vehicle, by appointment only. 2. I was afraid that the car was going to blow up or the brakes would not hold. 3. No, the problem has not been reproduced or inspected. 4. No, the vehicle or component has not been inspected. 5. NO, there were no warning lights to let me know there was a problem.

2017 GMC Terrain motors consume oil at an excessive rate (1 quart per 1,000 miles). Getting an oil change every 5,000 miles, even consistently, puts the engine at risk for major internal failure and safety risks to the passengers. My engine in my 2017 GMC Terrain has a broken timing chain and internal damage due to the excessive oil consumption issue. The engine will have to be replaced. GM has known about this issue for years. GM is in several lawsuits for this issue, but GM has failed to recall the parts of the motor that are excessively consuming oil. They refuse to help cover repair costs even though the costs are due to their poorly designed motor.
