My vehicle stalled while driving on a busy highway & I had no option but to pull over, which left me & my family in a very dangerous position. Had to remove my daughter's wheelchair onto a tow truck as the vehicle had no power to use the hoist for her powerchair. Again, on the side of a busy road! Towed the vehicle to a GM dealership, who stated there was catastrophic engine failure & the engine had to be replaced. Had no way to transport my daughter until I got a new engine since her hoist was stuck at the dealership.

1) The engine began making unusual noises. I had the vehicle towed to the dealer. It is currently at Zimbrick Eastside in Madison Wisconsin. 2) The problem was noticed prior to my family being put at risk only because I noticed the noise happening while we were parked. 3) The problem has been confirmed. The dealer is doing a complete engine replacement. However, as of today, it has been at their location for over 30 days. 4) To my knowledge the vehicle has not been inspected by the manufacturer or any other 3rd party representatives. As of today, there has been no correspondence between myself and the manufacturer. 5) There were no warning lights, messages or symptoms prior to the problem. The problem first occurred on Saturday [XXX]. The vehicle has 19462 miles and we are the first owners. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car has made a high pitched metallic rattle on cold start ever since I received it. I have taken it into the dealership multiple times for this and have had the lifters in the engine replaced but they never addressed the other noise, which I have video evidence of. The car died at 24,740 miles on the odometer in the middle of a highway in the middle of nowhere. The vehicle started to feel like it was braking on acceleration, there were no warning lights. The vehicle just lost acceleration power and I had to coast to the shoulder. Luckily I had time to pull over without interference from other traffic. Once on the side of the road I tried to crank the car again and a very loud metallic sound happened that sounded like I threw a wrench in a fan. The car lost electrical power very shortly after. I called onstar for help and she asked if I could shift the car into neutral which I could not. They had problems finding anyone that wasn’t hours out that could come tow my car and suggested that I try to find an alternate method of transportation since a wrecker service probably wouldn’t transport my entire family. Uber was not around to get me, Lyft was not around to get me and there was no taxi service. I had to rely on the local fire department to rescue us as it was hours with myself, my two children and my dog on the side of the road in 90F heat. Once at the dealership they confirmed it was indeed a catastrophic engine failure and I am currently waiting months for a back ordered engine with a rental I’m paying partially out of pocket for, in a car that’s entirely way too small for my family with no ETA on the engine in sight. I know multiple people personally who this has also happened to, same exact scenario and same exact engine just different model years.

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)

The engine had a bearing fail causing the engine to knock and make loud noises. The engine has been replaced and is at GMC corporate investigation center. GMC installed another engine that is also doing the same thing 150 miles after it was replaced. My families safety was put at risk because the motor could have locked up or exploded with us in the car causing a crash or possible fatality. Yes the problem was found at the dealer and caused them to investigate which is when they found the failing bearing. Yes, GMC corporation has the failed components and identified the engine needs replaced. They have yet to comment on the second engine that needs replaced. There are no warning lights to identify this issue, The lack of notification from GMC could cause drivers to be hurt by not knowing their car is failing.

I purchased my new GMC Yukon XL in October 2024. In February, with about 9,000 miles on it, I was approaching a highway intersection and beginning to brake. My vehicle put itself into Neutral, and then shut off -- while I was still moving. No dash lights came on, except for a message stating that I needed to press the brake and restart my vehicle. I took my vehicle into the dealership where I purchased it and they kept it for 8 days. They were unable to reproduce the issue and didn't do anything to mitigate the problem except for doing a "radio update" and adding lubricant to a window track. I was told I have to wait until it happens again and try to record it.

Total engine failure at 12,307 miles without warning. The engine turned off while driving on the Interstate - a message appeared on the instrument panel that said "Press start". We coasted to the shoulder and the car was towed to the dealership where the diagnosis was a failed L87 V8 engine. I'm aware of 3 others with the same engine (2024 Denali, 2024 Escalade, 2024, Silverado) that have also experienced this issue. After some research, this appears to be under review by the the NHTSA. This was a dangerous situation with an engine failure at highway speeds, at night, on an unlit well-traveled Interstate with 4 children in the vehicle. The dealership stated that my repair is behind 2 vehicles awaiting the same engine replacement.
