FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
The console screen that control many vehicle functions will often not boot up when the vehicle is started. Screen crashes have also happened while underway. The screen will be unresponsive to both touch and physical controls. Systems unable to be controlled include safety cameras and sensors, climate control, navigation, gauges, infotainment and others. I have attached a diary of specific issues and work arounds attempted. The dealership and GM do not appear to have methods of fixing the issue at this time.

ENGINE, FUEL/PROPULSION SYSTEM, SEATS
In January 2021, I purchased a new 2021 GMC Yukon Denali from a GMC dealership, which currently has only about 27,000 miles. To date, several recalls have been assigned and completed for my vehicle. per the websites for GMC and your agency. However, based on published recalls for my vehicle and a repair that is currently underway, I have reason to believe that my vehicle should have been subject to three prior recalls for which it was not [NHTSA ID Numbers: 20V735000 (Front Seat Bolts), 25V274000 (V8 Engine Failure, and 21V739000 (Fuel Power Control Module] Currently, the fuel pump control module is being replaced at a local GMC dealership because it failed last week and left my stranded at home. GMC issued a recall for this in 2021, but my vehicle was not included. Aside from risk and inconvenience, this is also costing my over $300 for a rental. Secondly, though my vehicle's make/model/year is cited in GMC's ongoing engine failure recall, which you are investigating, I have not received a recall notice. I note GMC's financial interest in minimizing vehicle's it recalls for such a costly repair. I have inquired with GMC and two of its dealers and have only received reiterations that my vehicle has not been subject to GMC's recall, which I already knew. I have not been given any explanation for why my Yukon has not been recalled despite my inquiries. Lastly, GMC issued a 2021 recall for front seat bolts; however, I did not receive a notice for my Yukon. I have occasionally felt slight movement in the driver's seat since buying the vehicle. Based on reason and facts, I am alleging that GMC appears to be artificially minimizing recalls and notifications for vehicles that are in fact impacted by defects in their vehicles.

ELECTRICAL SYSTEM, ENGINE
A side detection module pin was corroded and was disrupting the electrical signals to major vehicle components, such as the dash (DIC). The DIC would lose communication with the rest of the vehicle while driving so no vehicle operation data was visible such as speed, alerts messages, etc. This likely also caused engine failure due to the incorrect operation of the afm which is on the same electrical circuit. No warning messages were given. The bad side detection module was diagnosed and fixed at a dealer and shortly after engine issues were noticed.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, STEERING
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)

ENGINE, POWER TRAIN
My vehicle is currently in repair due to a known issue with GM. GM has put out a Technical Service Bulletin 20-NA-038 referencing a "well-known" problem with Cylinder 5 failing in 2021 5.3L and 6.0L engines. However, there has not been a recall. Ironically, there were other vehicles brought to the dealership (Sam Boswell GMC in Enterprise, AL) for the same repair on the same day as my vehicle. I'm hoping to get an initiative started for a recall

ENGINE, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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.

ENGINE
We experienced catastrophic engine failure consistent with the current outstanding recall. A GM dealership replaced the parts that failed (crankshaft and connecting rods) however, based on the recall that was issued, the serial number on our engine would qualify under the remedies indicated by GM for a complete engine replacement, however, our VIN number is not currently included in the recall even though our year, make and model for the car and engine are consistent with other recalled vehicles. The GM dealer indicated that the catastrophic engine failure was not due to any lack or neglected maintenance and felt that our vehicle should be included in the recall. My wife and two toddler children primarily use this vehicle and I have serious concerns about their safety and would like to feel confident about their use of the vehicle.

driving the vehicle on a regular city street when the flashing engine light came on out of nowhere. immediately pulled off and had the vehicle towed to my dealership. result of the inspection, i have to replace my engine. as soon as i started researching the issue it is clear that this truck should be part of the GM recall. it is a known issue that GM slow played for years, but as of now this vehicle is not part of the recall. it is the same engine and failure mode as the 600,000 unit recall, but mine isn't covered by the recall leaving me responsible for their known and documented manufacturing issues

SERVICE BRAKES
At low idle speeds like in a parking lot we almost hit another car because the brakes were very hard to press. No power brakes. Felt as I was having to stand on the brake pedal with both feet to stop my vehicle from hitting another car at a grocery store parking lot going 5 mph! A light flashes on and says”service brake assist “ light goes away and drives normal and brakes normal except when you get to a stop sign, or traffic light. This happens a few times and I’m not driving the car because of it because I might hit someone
