2023 GMC YUKON Complaints

The contact owns a 2023 GMC Yukon. While the contact's wife was driving approximately 5-10 MPH on a city street and approaching a stop sign, the vehicle experienced a failure and became inoperable. The contact stated that while the driver was attempting to restart the vehicle, the battery warning light and engine warning light illuminated, and the "Low Battery - Start Engine" message was displayed. The vehicle was towed directly to a dealer to be diagnosed. The dealer was unable to determine the cause of the failure but provided an estimate for the valve springs inspection. The vehicle was not repaired. The manufacturer was notified of the failure and was working with the dealer to determine how to repair the vehicle. The failure mileage was approximately 71,481.

The vehicle is equipped with “rain-sensing windshield wipers” but they do not work due to poor design. They should not have failed this quickly (33,000 or so miles). The windshield wipers must be manually activated because of this defect, but since the manufacturer thought they would be automatic, they made the manual activation very hard to access. It is very dangerous trying to activate them while operating the vehicle because A) your eyes are off the road for an extended period in poor conditions and B) the control is in a hard-to-reach area. You have to turn the nob 6-7 positions to put the wipers on low or high, and for the first 5 positions the windshield wipers don’t activate.

The panoramic sunroof has a substantial leak, even though the 2023 vehicle only has 33,000 miles on it. The drain lines are clear but water continues to significantly leak out of the rear passenger seatbelt housing onto the seatbelt. There is also significant water drainage through the rear interior lights onto the upper legs of rear passengers (children in car seats), causing a severe electrical hazard. The leaking caused by the drainage defect affects the interior lighting, the seatbelts, and is a potential electric hazard. This seems to be a common occurrence and the manufacturer should repair their defective products. The drainage pipes are obviously either not assembled correctly or the materials don’t hold up. This should not be occurring in a $55,000 vehicle with 30,000 miles. I have multiple videos I can provide but the file sizes are too large to upload, so I took screenshots. I am going to pay for the repair but I should be reimbursed by GMC.

My car started making a knocking noise under the hood 2 days prior to it breaking down (6/19 & 6/20). On 6/21/26, I was driving down the interstate WITH my kids in the car and it shut down on its own. Lights came on my dash and the vehicle quickly slowed itself down and when I pulled over to a complete stop, the vehicle shifted into neutral and shut off. I was not able to crank it back up and had to pay a tow company $243 out of pocket to tow it to our local dealership in town. My insurance only covers $200 for towing. I am a week without a vehicle and just found out Friday (6/26) that a new motor will have to be ordered but it is on back order with no idea on when it may arrive. I cannot get an answer from GM or my local dealership on if a rental will be provided. I cannot make 2 car payments but I also have a job and cannot proceed without having a vehicle to drive. This has put me in a bind for a week already with no solution in sight. I expect GM to fix my problem asap since it is theirs to fix!!

Engine knocking vechile had loss of power. Had towed to dealer. Throwing all kinds of codes 6.2 L v8. Truck passed GM crap test in September and here we are at 59,000 with a blown motor. Lucky it did not go out under power and kill me or my small kids and family that was going to vacation with this truck the next day

Vehicle had previously undergone the GM 6.2L engine recall inspection on October 17, 2025, and was determined to have passed. On June 13, 2026, at approximately 80,390 miles, the vehicle suddenly lost propulsion while being driven with five children in the vehicle. The vehicle became inoperable and required towing. Dealer subsequently diagnosed engine failure and has ordered a replacement engine. This failure happened with out warning.

My wife and I were traveling to Denver CO to pick up my son and grandson from the airport. The engine started to make a very exaggerated rattle. We found a dealership near our motel where we took the vehicle to and were told not to drive home that the engine needed to be replaced. We had to arrange our own transportation for both us and the vehicle 8 hrs back to our home in Rapid City, SD where our local dealership replaced the engine. The vehicle had approximately 65,000 miles when this occurred. Fortunately we were in a populated area when this occurred as there is a lot of very sparsely populated area between our home and Denver. This malfunction not only cost me a lot of money but also put my family at risk in unfamiliar areas.

lost power going down highway and coasted to a stop on the side of the road. car was towed to a nearby gmc dealership and after inspection a new 6.2 motor is needed. I did not notice any warning signals when I lost power.
