About mid October while driving at 60 mph it shut down again almost causing a wreck went to 30 miles per hour again. Hurt my wife’s neck when it reduced speed so quickly. Took back to dealership and I told them this car is dangerous this was with about 20 k miles Been in shop was told it is scanning with 22 repair codes we have not had the car for 5 weeks and are trying to work with gm and dealer to get us out of it. But as of this report no progress. On interstate in city traffic this car will hurt or kill many people. I’m refusing to let my family or myself drive it. There is no warning when it will flash lights in dash and reduce speed. Also the front crash sensors went out and are currently not working we have all service records and paperwork that has been done including maintenance records We were given vehicle back with no warnings. I went to Nita’s and ran vin and it still shows issues. We are still making payments but driving a loaner car. The car is dangerous. I advised the dealer the first time it happened. I didn’t want it back. My wife went and got it and it sis it the second time and now she agrees it is dangerous contacted GM and they want to fix it but dealer implies they can’t ?..

ChatGPT said: There is a design flaw with the automatic light function. When you turn the knob to disable the automatic lights to avoid blinding someone while parked, the knob returns to the auto position as expected. This is a good system to ensure that the next time you start the car, the lights are in auto again. The issue is with the way the system indicates what is happening to the driver. When the lights are set to auto, the “auto” indicator on the knob is illuminated. If you turn the knob to running lights or full lights, the corresponding indicator lights up as expected. However, when you turn the lights off, the indicator light returns to “auto” even though the lights are actually off. While the physical knob should return to auto to make sure the system resets properly at the next startup, the indicator should switch to the “off” position so the driver knows the lights are off. I drove off in the city and assumed my lights were on because the knob said auto, but I later realized they were off. This creates a serious safety hazard. There is no way to know in that situation if your lights are actually on by looking at the knob unless you cycle the lights again. A recall should be issued to change the software or replace the button to make sure that this is clear to the driver.

On 15 Aug 2025, I was driving this vehicle on Rte 151 in raccoon township with my 2 children when the vehicle suddenly and unexpectedly experienced a “loss of propulsion” with a corresponding uncommanded shift to “neutral”. Attempts to shift the car back into drive were met with a “parameters not safe” caution. I was fortunate enough that the vehicle behind me was able to slow and an accident was avoided. The thought that this could have happened with my family on the highway, during adverse conditions, or any other scenario is frightening to say the least. Other owners of affected models weren’t as fortunate.

The dealership diagnosed the vehicle and noted a critical issue with the engine and transmission. Dealership recommends engine replacement. Vehicle is less than a year old with 15,400 miles on the odometer. This particular vehicle is not impacted by the GMC recall on their engine, however is has the same engine failure.

I am the owner of a 2024 GMC Yukon (VIN: [XXX] ), purchased from Hatchett Buick GMC on [XXX]. This vehicle was purchased at a high price with the expectation that it would provide reliability and keep my family safe. Unfortunately, that is clearly not happening. The Yukon continues to suffer from severe power loss that neither the dealership nor GM technicians have been able to diagnose or repair. In addition, this vehicle is subject to an unresolved engine recall, further undermining safety and confidence in the vehicle. Multiple times while driving I have had total power loss with no warning or indicators of this happening through lights or warnings on the vehicle. This is separate from the engine recall issues I am currently experiencing as well. While driving the Yukon will lose all electrical power. The vehicle is still currently at the dealership trying to be diagnosed. It has been 2 weeks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had several time that going down the highway at around 70 MPH with the cruise control on. Know other cars or trucks around me, my car loses power, put on the brakes. If I press on the gas petal, the car will accelerate. Never a warning, scares the heck out of you. Fortunately when this happens I have never had a car or truck behind me. If there would be a car or truck behind me, this could cause a collision for sure. No warning lights comes on. I've told the GMC dealer twice about this. Twice I was told to make another service appointment to bring my Yukon back. I was told that no service tech was available to look at this at this time.

While super cruise was engaged the car changed lanes automatically without any action on my part. The problem is I had set the automatic lane change feature to only activate when the turn signal was switched. While examining the vehicle settings I discovered that the feature was set to automatic not turn signal activated. What cause the software to change this setting? The service tech could not find any problem but guessed that when the software is updated it goes to a default setting. This is wrong. Setting should not change. The setting also changed on opening the tail gate with my foot. This setting was turned off.

I am the owner of a 2024 GMC Yukon Denali/AT4-T1, currently subject to GM Program #N252494000 for the L87 Engine Loss of Propulsion engine defect that can cause sudden engine failure, loss of power, and safety hazards. My vehicle has approximately 18,000 miles and is my primary mode of transportation. GM has informed me that I cannot request an immediate inspection and that they are randomly selecting affected vehicles for inspection without a clear timetable. This means I must continue driving a vehicle with a known safety defect that could fail at any moment — creating an unreasonable risk for myself, my passengers, and others on the road. My dealership has confirmed they cannot perform the inspection until GM activates my VIN in their system. No estimated timeframe has been provided. Given the severity of the defect and the potential for catastrophic failure without warning, I respectfully request that NHTSA investigate GM’s phased approach to inspections and determine whether this practice is consistent with the safety obligations under 49 U.S.C. Chapter 301 and related regulations. I also request guidance on how I can have my vehicle inspected immediately to mitigate risk. Thank you for your attention to this matter.

I had just backed the truck out of a parking space (while turning) and shifted the transmission into 'Drive' with my foot pressing the brake pedal (not the gas pedal). When I took my foot off the brake pedal in order to transfer it to the gas pedal the vehicle suddenly accelerated forward without my foot ever pressing the gas pedal. The vehicle traveled forward about 20 feet before I was able to stop it by pressing the brake pedal. I am a retired General Motors Safety engineer and I know I was not pressing the gas (accelerator) pedal when this sudden acceleration event occurred. I believe this type of event occurred one other time while I was driving this vehicle. However, I am not as clear about the circumstances surrounding this previous event.
