2023 GMC YUKON Complaints

While traveling on the interstate my vehicle shuttered and lost power we went to a friend’s neighborhood and the vehicle stalled when we pulled in no lights had come on until then and a knock had started. With no where to pull over I finally got the vehicle started and drove it straight to our friends house and left in on the side of the street. I had to take there vehicle home and called ONSTAR to tow it to the dealership. I have to pay for the over mileage because I was out of town when it happened.

The vehicle underwent a recall inspection on September 8, but on October 2, the vehicle still experienced a serious engine failure. The vehicle was undrivable, and the dealer inspected it and opened a TCA case. However, General Motors stated that it had passed the recall test and was not covered under special warranty, and asked me to pay $5,000 for vehicle repairs. I believe this is an engine malfunction related to the recall, and the manufacturer should replace the engine for me free of charge and refund my 5,000 .

The vehicle has experienced numerous losses of power, it has nearly stalled during normal operation, there is a horrible knocking noise coming from the engine. I have had the vehicle into the dealership who state they are unable to recreate the issue, and since the vehicle has been turned off the recorder shows noting either. They have performed an inspection and changed the oil, but the vehicle still has the issue. It knocks and shudders like it's cold, it comes very close to stalling and then seems to recover, this has happend twice while making left hand turns, it has completly lost power even while depressing the gas, but again they indicate they can't recreate it, so there is nothing they can do. I am scared for my safety, and that of the child I drive daily. There have been several instances in the last few months.

On May 23, 2025, I purchased a 2023 GMC Yukon XL VIN: [XXX] from the GMC dealership.? At the time of sale, I specifically asked about the active GM engine recall. They assured me the vehicle had been inspected and was unaffected. On October 30, 2025, the engine catastrophically failed on a highway while my family — including my two small children — were in the vehicle. This created a dangerous emergency situation as I had to avoid high-speed traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Purchased 2023 GMC Yukon on August 21, 2025 and after starting the vehicle on October 2, 2025 the whole instrument panel cluster malfunctioned, failed to turn on, currently does not work and is available for inspection upon request. The instrument panel cluster is all black, it shows glitching flashing white lines on the right side of it therefore being unable to read the speedometer, fuel gauges, tire pressure, oil life, engine temperature, etc.. Prior to the instrument panel cluster malfunction, there were no warning indicators. Being unable to view the instrument cluster, makes the vehicle hazardous & risky to utilize for me and my family. This vehicle has not been confirmed or inspected at this time.

my 2023 GMC Yukon Denali (VIN: [XXX] ), which is included in Safety Recall N252494003 for a known defect affecting the L87 6.2L V8 engine. My vehicle was first inspected under warranty in December 2024 at Serra Traverse City Buick GMC due to a burning smell. I was informed at that time that no issues were found. I was later told by the former service manager that the technician who evaluated my vehicle during that visit was let go due to poor workmanship and lack of product knowledge. Since that time, on two separate oil changes — January 8, 2025 and May 9, 2025 — my engine was found completely out of oil, with no oil on the dipstick. The documentation had to be retroactively added after my request. This pattern raises serious concerns about oil consumption or internal engine damage consistent with the recall defect. The dealership declined to replace the engine or perform any further diagnostics beyond the standard recall inspection. I was advised to retrieve the vehicle. However, I remain deeply concerned about the long-term safety and reliability of this vehicle, especially given GM’s acknowledgment that this defect may lead to engine failure and loss of propulsion. I have made multiple efforts to escalate this issue through both the dealership and GM’s customer service line. I was advised by Service Advisor [XXX] to contact the GM representative for regional review. He directed me to file a bbb claim.. Both GM and bbb denied my claim, stating out of warranty. However, the dealer explained that my issue were documented under warranty and would be handled appropriately if the issue persisted. GM contacted me an offered a $4000 credit. Unfortunately the problem still persist. I’m 3000 miles from being due for an oil change and again have no oil on my dipstick.

On star module completely out No internet on vehicle No ability to use OnStar during an emergency Unable to connect to vehicle Noticed it all stopped after a vehicle update

My telecommunications module is no longer working for OnStar, which means I can no longer call if something happened. The Wi-Fi is not working. The vehicle thing is on recall and now my check engine light is on.

Electric trailer brake control module intermittently disabled trailer electric brakes while towing electric brake equipped trailers. This is the same issue addressed in GM service bulletin N232414840 which addressed a similar issue associated with GM pickup trucks. The loss of trailer brake utilization may create a safety hazard resulting from longer stopping distances. The factory control module was replaced with a redesigned module purchased from GM and the problem went away. I am of the opinion that the factory-provided module is a deficient design which warrants replacement by the vehicle manufacture.
