2021 GMC YUKON Complaints

At the time an oil change is needed, there is a warning light that says "low oil pressure and low oil." There also has been a "slipping" of the engine at around 60mph. GMC dealer states it is a torque converter. I am worried that the engine will fail or stall while driving The fuel pump control module has been replaced. Motor is not covered under the current motor recall and taking vehicle to transmission shop to have it checked as well

Clicking/rubbing noise when turning slowly. Rear differential issue diagnosed by dealer.

I'm vehicle has experience both active recalls for similar model year but my VIN isn't listed as been one that is covered by the call. 25V274000 and 21V739000.

Low engine oil message keeps flashing after less than 2,000 miles of driver. Excessive oil consumption. Took vehicle to GMC dealership and it was confirmed that an engine replacement or replacement of the pistons and rings is necessary. Only 77,000 miles on the vehicle. My car is currently not a part of the massive recall.

Vehicle indicated that the suspension system was disabled. Vehicle then lost power and disabled itself driving through the Eisenhower Tunnel I-70 Colorado. This tunnel is over a mile and a half long. We called 911 as we were very worried we were going to have another vehicle crash into us as there are no breakdown lanes. The tunnel had to close to West Bound Interstate traffic and the vehicle had to be dragged up a tow truck because the back wheels were locked. The CDOT tow truck then dropped our vehicle outside the tunnel. We had a private tow company (again dragging the locked tires onto the next truck) take us home and to our personal repair shop. Vehicle was diagnosed as a blown engine. We then had to tow our vehicle, again dragging tires, to a GMC certified shop. We have spent $1502 on towing. This vehicle has approximately 57,000 miles and was 9 days out of the powertrain warranty. The repair shop has the same diagnoses and a dead battery because we could not turn the vehicle off. We have no vehicle to drive as ours sits at the repair shop waiting for parts. GM told me we were out of warranty and would not help. The dealership says GM may do cost sharing but will still cost us $2000.

I got 3 messages on the dash going off simultaneously 1. Service Traction Control System 2. Forward Collision System unavailable 3. Service ESC I could feel the truck bogging and shaking a little at this point Then soon after the check engine light was flashing and it was noticeably misfiring and rough idling. I pulled some codes at Oreillys and got back 1. P0300 misfire 2. P050D cold start rough idle

Routine oil change by professional local mechanic. Upon completion we were told that the vehicle would not turnover. The mechanic diagnosed and found that were 2 recalls for our vehicle - one for the fuel pump module and one for the engine. We had our vehicle towed to the local GM dealership. They then replaced the fuel control module. GM tried to manually crank over but engine seized once again. We spoke to the GM Advisor prior to this and were told that our vehicle was not part of the engine recall because our VIN was not listed as part of it even though our vehicle had the same exact issues as described in the engine recall and was for the exact year/make/model of the engine. The dealer quoted us $14,896 to replace the engine. They stated they would submit a Goodwill claim to GMC to help discount the cost to repair/replace the engine. The dealer called back later that day and said GMC would be willing to cover 30% of the cost so our expense would be around $10,000. All this for a vehicle we've only driven for less than a year and a half. The vehicle went in for a routine oil change and has never had any issues prior to this. This happened suddenly without any sort of warning. To make matters worse, our powertrain warranty expired a day or two before this occurred. We are still trying to fight with GMC to cover this engine failure. The car has less than 75,000 miles and is only used for basic personal needs like driving to school and the store so it is shocking that the engine would suddenly fail like this and to make matters, the manufacturer refuses to take responsibility for it and to cover it under the recall even though there has been known widespread issues with this engine.

On November 14,2025 my engine failed on the highway going 80 mph to 0 mph in the passing lane. Almost caused a major accident on US23. I’ve asked my dealership Bowman Chevrolet repeatedly to inspect my engine for the recall and have been denied every time. Most recent was October when I had my oil changed and I was told it wasn’t my turn and the recall for my vehicle was pending. I had my vehicle flatbed towed to the dealership where it sits dead in their parking lot. Thank God we didn’t die on the freeway that night. It was a horrible experience.

While driving vehicle on 11/08/2025, vehicle made a popping noise and loss power. We were out of town and had to pay out of pocket to have vehicle towed to a dealership and hour away from our home. Dealership diagnosed issue with engine failure due to lifter fell and caused damage to cam shaft and bore. I will be without a vehicle for an additional 2 to 4 weeks waiting on a back ordered engine from GM, and continue making payments on vehicle as well. This issue seems to be an ongoing problem that GM is ignoring…….GM should compensate towing, car rental, and repair/ replacement charges due to failure.
