My 2023 Yukon AT4 was taken to certified GMC dealer in November 2025 for the engine recall. The dealership gave my vehicle a clean bill of health at that time and the recall repair was cleared. On Friday, 2/13/26, myself and 5 other family members were en route to my godfather's veteran funeral service in Newtown, PA. We were going 75mph in the middle lane of the PA Turnpike when the motor seized up and vehicle lost all steering control and power. Since it was the side of the turnpike, we were limited in resources and stranded, missing the funeral service due to the length of time it took to get the vehicle loaded on a tow truck. Since the vehicle was unable to release the parking brake, the tow driver(s) were struggling to tow it. My husband, ended up having to go under the vehicle (on the side of the turnpike) to disengage the parking brake to help the tow drivers. This could have been a catastrophic situation. My vehicle was taken to a different GMC dealer than the original one that

My 2023 Yukon Denali is part of the L87 engine loss of propulsion recall. On August 28, 2025 my Yukon was inspected by Sterling McCall Buick GMC (where I purchased it) and it was deemed to have passed inspection. They changed the oil and installed a new oil fill cap and filter. On February 13, 2026 I took my Yukon to my mechanic for an oil change. Upon initiation, he advised me that he found the oil stick to be dry, no oil on the stick. There was no leak.

Post initial remedy, which included oil sand cap replacement to 0-40, as directed by the manufacturer's recall documents, and passing the PicoScope test on August 26, 2025, the vehicle lost propulsion while traveling 58 mph, in the center lane of a busy, notoriously dangerous Saeford-Oyster Bay highway. At the time, the vehicle was occupied by a 2-week-old infant, the child's mother, and a dog. Prior to the failure, there were no indications of a pending or present issue. The vehicle's engine shut off, it shifted into neutral, and upon stopping, it shifted into a parked position, where it remains to date. Subsequent to pulling the vehicle onto the shoulder, the engine failed to restart. Approximately 6 hours later, the vehicle was towed to a GMC dealer, which subsequently confirmed that the engine is seized. The dealer submitted a report to GM to remedy the condition, pursuant to the manufacturer's recall instructions, but the manufacturer is yet to approve the remedy.

Rear camera for in cabin rear view is improperly sealed for cold weather and constantly fogs which renders the camera worthless. I was also sent brand new side lights from gm that were improperly sealed and built condensation them after a month or two.

While driving down the road, my 2023 Yukon 6.2L engine shut down, shifted to neutral, and a message on the screen said “press start again” leaving my family in a powerless vehicle in the middle of the road in moving traffic. There were no warning signs nor is my vehicle included in a current recall. The vehicle will be taken to the dealership tomorrow morning.

seatbelt has come undone on its own multiple times on the drivers seat. nothing was touching or near the red release button when this has occurred. it is not immediately happening but happens while driving. i think its happened five times in the past 1-2 months. i cannot figure out a rhyme or reason. i have never experienced this happen on any vehicle previously.

At right under 40,000 miles the engine blew. The GM dealership that repaired my car would never tell me exactly what happened, and they were very sketchy about the whole experience, but it required a complete engine replacement from GMC when the engine quit working.

Full system error codes displayed on dashboard, Drive Train Error, Steering Colume error, brake system error, "Car will not operate a speed greater than 40 mph, happened 3 times dealership on first inspection advise it was an interface with the factory installed Lojack system and disconnected, Last same sincerio (note..no Lojack connected) same as above the new diagnosis is the battery low voltage to system and throwing everything off.

2023 Yukon Denali has now broken down twice, leaving myself and my family (husband and children). This last time was on Friday 1/16/26 while we were out of town, the car began malfunction and then we had complete engine failure while drive 70mph down the highway, again, leaving my family stranded on the side of the road, on a busy highway, in an unsafe environment in the winter.

the Engine started running rough and the engine light came on. The dealer told my wife to drive there in limp mode (~15 miles), she did so on back roads. The diagnostics said that cylinder 7 was not firing and teh fuel injector control circuit was bad. they had to replace the Engine Control Unit.

While driving approximately 63 mph on a busy roadway, my 2023 GMC Yukon experienced a sudden failure of the brake system, including loss of normal braking capability along with failures of the Electronic Stability Control (ESC) and ABS systems. The vehicle displayed warning messages stating “Brake System Failure” and “Service ESC” and entered a reduced-speed mode. Prior to this incident, there were no warning lights, messages, or symptoms indicating a problem. During the failure, the brakes became largely unresponsive, placing me, my two minor children who were passengers in the vehicle, and surrounding motorists at serious risk of a high-speed collision. After extended deceleration, a minimal amount of braking power partially returned, allowing the vehicle to eventually come to a stop. The vehicle has not yet been inspected by a dealer, manufacturer, police, or insurance representatives, and the issue has not yet been reproduced or confirmed by a service center. The vehicle re

We received a notification that our 2023 GMG Yukon Denali Ultimate engine needed to be tested as a part of a recall. We took the vehicle to our local GMC dealership. The engine was tested and determined to "pass". The "pass", we were told, meant that we did not need a new engine, just thicker oil, and that the engine was safe. Mind you, our car was a custom order, took 8 months to receive, and is not even 3 years old. The vehicle is my everyday driver. I have two kids and live in a large city with a lot of traffic. A few months after it was determined to "pass", I was driving with my kids and dog in the car. The abruptly stopped, putting itself in neutral. Luckily, I had just turned off of a major interstate and onto a side road. The car would not start or move out of neutral leaving me and my kids in the middle of the road. It now needs a new engine. Prior to this issue, the battery died a few weeks after we took delivery of the vehicle. SAFETY!!!! If this happened just a few minutes

However, there was a loud noise immediately followed by lose of engine power.
