NHTSA Complaint #11650948 — 2024 GMC YUKON XL

V8 6.2L ENGINE on [XXX] at approximately [XXX] exactly 10 months after purchasing the Denali at 9,484 miles my Denali started to make loud noises and when we got to the stop light [XXX] and [XXX] in Long Beach California the Denali started to shake violently and ultimately shut down in the middle of the road. My daughter and I were traveling on the way home from the doctor’s office and when Denali shut down, I called AAA, and they advised me to call 911 since Denali locked up in park and could not get it in neutral to push the truck to the side of the road. This was very dangerous as vehicles were speeding past us. We stayed in the vehicle until an officer arrived. Then about 15mins later the tow truck arrived and made the area safe with cones and flashing lights. I did put my hazard lights on but in the middle of the day it was very hard to see. AAA was able to disengage the parking to neutral as he mentioned that he just towed another Denali off the road. This is a huge concern for my family and me. I didn’t get to see how he did it because I was with my daughter safe in the Tow Truck. AAA then towed the truck to Penske GMC in Cerrito Auto Square and arrived at 1:48pm. Service advisor then said to leave at garage door and will assess the vehicle tomorrow morning. Albert, the Service advisor, proceeded with giving me paperwork for the Denali and an Enterprise rental car that was located across the street. We had to walk because the shuttle was down (another concern). Albert the service advisor called me the next day [XXX] and advised that the first auto technician suggested the motor seized up. I was advised to wait until the Engine Specialist assessed the motor. Albert the service advisor calls me March 5,2025 @ 11:15am and Engine Specialist did confirm that the motor did seize up and will need a new one. The motor will take approximately 2 weeks to arrive and 3 days to install. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
