Two weeks after purchasing our 2022 slightly used Cadillac Escalade, my family and I were on our annual Thanksgiving camping trip. December 1, 2024 we were on our way back home from this trip on a very busy highway frequented by semi trucks and large RVs (nearby desert camping). While driving and towing a small trailer at approximately 60 mph on this highway, my vehicle unexpectedly shut off forcing me to act quickly to avoid an accident. (Semi trucks and RVs cannot brake and respond as quickly and there were several in the lane next to me, and approaching behind me). I was able to pull over to a shoulder before the vehicle slowed to a complete stop. After attempting to restart my vehicle I was unsuccessful and contacted OnStar to tow me to the nearest dealer. My family and I waited for 5 hours on the side of this highway with semi trucks and RVs passing us at 60 mph. The vehicle was towed to the nearest dealer, yet 100 miles away from our home, and remained in the dealer’s possession for 29 days. The dealer determined my vehicle experienced engine failure and was in need of an engine replacement. I have only owned this vehicle for 1 and a half months.

As i was driving on the highway in the left lane at approximately 85mph, without any warning lights from the vehicle, the car completely shut off. I had to cross over three lanes of traffic on a busy highway with the car completely stalled out to get to the breakdown lane. The vehicle was towed to my local Cadillac dealership where I was later informed that the engine had completely seized. The service department at the dealership indicated that this is a known issue with the engine in the model year 21-24 Escalades. He indicated that there are faulty bearings that send metal particles through the engine causing it to seize.

On [XXX], my wife and I were stopped in traffic in Baton Rouge, Louisiana at approximately 7:35pm. Another vehicle failed to stop due to being distracted on his phone and rear ended my 2022 Cadillac Escalade. My wife and I were both injured. None of our airbags deployed and the On-Star system never came on and never detected the crash. By the airbags never deploying, this caused my wife to hit her head on the dashboard as well as on the speakers on the passenger seat. It happened in front of a fire station so they heard the crash and immediately ran out the fire station to help us. The vehicle just arrived at the collision center on 10/17/2024 and they will begin inspection for repairs. None of my emergency warning lamps or any other lights or messages came on in the vehicle. The vehicle just appeared normal like nothing happened. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While operating my vehicle at speeds exceeding 70 mph in the leftmost lane of [XXX] , the vehicle unexpectedly shifted into neutral. Despite attempts to manually select a driving gear, the transmission failed to engage, causing a rapid loss of speed. In an effort to avoid a potentially hazardous situation due to the decreasing speed in a high-speed lane, I attempted to maneuver the vehicle towards the right shoulder but was unable to because of the oncoming traffic. It became necessary to bring the vehicle to a complete halt, turn off the ignition, and then restart the engine in the left lane with traffic building behind me. The vehicle managed to restart but with difficulty, allowing me to exit the highway and pull into a nearby gas station where it eventually stalled and could not be restarted. - The vehicle displayed no warning lights or error messages prior to or during the incident. - got the vehicle towed to Cadillac dealership for inspection and diagnostic testing. The Engine needs to be replaced - The dealership was unable to provide a conclusive explanation but noted that similar incidents had been reported with this model. - Independent research indicated a pattern of similar issues among owners of the same model, involving unintended shifts into neutral while driving. - Multiple online forums and consumer reports sites have documented complaints regarding this issue. [XXX] - The inability to maintain or control vehicle speed in high-speed traffic lanes presents a significant risk of collision. - Inexperienced drivers may not respond adequately to such unexpected vehicle behaviors, increasing the likelihood of accidents. This incident underscores a critical safety concern that requires immediate attention from both the manufacturer and regulatory bodies. I recommend a thorough investigation into the model’s transmission system by the National Highway Safety Commission.

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.
