2024 GMC Yukon

I HAVE HAD PROBLEMS WITH THE NAVIGATION SYSTEM WHERE THE SCREEN GOES BLANK. THE RADIO IS NOT RESPONDING AND SCREEN IS BLACK. WHEN TURNING ON THE SIGNAL LIGHT YOU CAN'T HEAR IT. THE SPEED LIMIT IN MY TOWN IS 25 AND AFTER AN UPDATE FROM THE DEALERSHIP IT NOW SAYS 55. I GET AN ALERT SAYING FRONTAL CRASH NOT AVAILABLE ATLEAST ONCE A MONTH. THERE ARE TIMES WHEN WE ARE DRIVING AND WE GET THE RED ALERT AS TO DETECTING AN OBJECT AND THERE IS NOTHING THERE. PARKING ASSITS DOES NOT WORK ALL THE 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.
