On October 23rd at approximately 0900-0915 hours I arrived at a friends house located at [XXX] . As I normally do, I pulled up into the driveway which has a pretty significant incline. I shifted the column shifter into park, and turned off the vehicle via the push button ignition switch. The parking brake/hill brake system automatically engaged as per normal operation. I exited the vehicle and before I could shut the door, the vehicle began to roll backwards. The driver's side door hit me in the right shoulder which pushed me to my left and caused me to roll my left ankle due to the down slope of the driver way. While I felt immense pain in my right ankle, I was able to jump back into the truck and slam on the brakes, causing both rear wheels to lock up and skid in the driveway. I then turned back on the vehicle, noting that the transmission position was still in park, and the parking brake/hill brake was still engaged. I had to disengage the push button parking brake/hill-brake, shift the vehicle from park into drive to move back up the driveway. This time I ensured that the vehicle did not move after following the exact same steps. My truck under went an approximately 30 minute software "upgrade" approximately 2.5 weeks ago. I believe there was an issue where the park sensor did not fully engage, leading the vehicle to believe it was still in an operational gear, however it does not explain how it was able to not only over-ride the parking/hill-brake itself, as well as allow me to shut the vehicle off and exit the vehicle. This safety hazard has caused me an injury that has already caused me to miss 48 hours of work (I am a federal firefighter) and will require more missed time should surgery be required. There were no warning lamps, the backup camera was not engaged, the only audible sound was the beep that the vehicle makes when engaging the parking brake automatically.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
