“main seal blew is in dealership now. it was not running right as i drove it was afraid it would die in the middle of the road. just inspected at the dealership. i got the engine light about a mile from my home where it sat till it went to the dealership.was over 4 quarts low with oil but never had oil light or anything else before it showed engine light.”
NHTSA complaint #11568685, filed 2024-01“I was driving back from out of state and all the sudden the engine just got loud. So I pulled over and check oil levels. Except there is no access to the transmission oil. The only way to check this is to remove the front driverside tire, take a bolt out and see if any oil drips out. This is insane that there is no dip stick. I am taking it to a mechanic on Monday but to not have quick access to this is wild.”
NHTSA complaint #11683172, filed 2025-08“The engine burns oils twice as fast as it should and gives no warning of a problem. I am 3 years into payments on this vehicle and the engine is shot due to this issue. I have under 80,000 miles but this is a major problem that GMC is not addressing its very frustrating I will have to pay off a damage car they sold and now buy a new for an obvious problem they won’t acknowledge”
NHTSA complaint #11520764, filed 2023-05“timing chain issues resulting in a loss of power of the vehicle while driving. The vehicle stalls out and shuts off. Or it will go into power saving mode and slow down to only 20mph. It did this to me one a MAJOR HIGHWAY and I almost was in an accident. Way to many issues with gmc owners and the timing chain on their vehicles”
NHTSA complaint #11498874, filed 2022-12“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.”
