I was on the interstate and when I was passing a vehicle in the middle lane the engine lost power, shifted to N. I tried going back to drive it would not shift. Stopped the suv and tried restarting it. When I pushed on the brake and tried to start it the whole vehicle would loose power to all my screens. I had this vehicle towed in back in September 2025 due to not cranking over when starting. They did the recall for the engine at that time. The engine light would randomly turn on but would go

2023 Yukon Denali XL 6.2l: GM oil change recall performed (October 2025) and GMC dealership noted no issues.

Next oil change at aprox 50K miles, no check engine light came on, but certified mechanic drained and measure oil level, 1.5 quarts low. Engine often sounds odd at cold start, ticking sound. Now an oil change is $100 more, due to special oil, but not compensa

On 12/22/2025 I took my 2023 GMC Yukon in for the L87 recall. After receiving information that my vehicle passed the recall they told me that the oil would be change to from OW-20 to OW-40 and that my oil changes would go up in price (double the price) due to the oil being a high performance oil. On 01/05/26 exactly two weeks and 616 miles later our engine and lights completely stopped working while driving it on the road!!! The vehicle would not start or switch into neutral so we could get the

On two separate occasions, while driving at approximately 60 mph on New York parkways, my vehicle unexpectedly shifted into neutral and lost power without warning. During the first incident, a message appeared instructing me to “press start to continue.” I was able to restart the vehicle and drive home. Two days later, the same failure occurred again under similar conditions. This time, after pulling over and pressing the start button, the vehicle shut off completely and became totally inop

I am reporting a catastrophic engine failure involving my 2023 GMC Yukon XL Denali, which was subject to a GM-issued recall related to engine failure. On January 10, 2026, at approximately 1:00 a.m., while traveling at highway speed (approximately 65+ mph) on a multi-lane highway, the engine suddenly failed without warning, resulting in a complete loss of power. I was forced to make immediate evasive maneuvers to reach the shoulder while avoiding semi-trucks and other vehicles. The sudden loss

Following a catastrophic engine failure in my 2023 GMC Yukon XL Denali, I discovered that the vehicle could not be shifted into neutral once the engine failed. This prevented the vehicle from being moved out of traffic if it had stopped in an active lane. The inability to place the vehicle into neutral after a loss-of-power event creates a serious safety hazard, particularly on high-speed roadways. In the event of a failure occurring in traffic, occupants may be left stranded in a travel lane w

Vehicle was taken to dealership and test was run. Service manager notified me it passed and told us about change of oil. Then recently engine stopped on us twice on the interstate with no power. We finally got it to the dealer and while they were test driving it lost power and they had to have it towed. Now we have been told we are needing a new engine and have not been given any time line. We have also read that many time the solution even on the new engine is not fixing all issues. We just wan

Catastrophic brake system failure. When leaving my home in Baltimore County, MD, at approx. 10:00am on February 3rd, my vehicle started up normally. As I descended down a hill in our neighborhood the brake system failed and the vehicle would not stop. By standing on the brake pedal I slowed enough to put the vehicle in park as I entered an intersection with the main road. I have since learned this is the 3rd GMC Yukon (years 2023-2024) that has had the same brake failure in 24 hours in our c
