On June 14, 2026, while driving approximately 70 mph on a Michigan freeway, the 6.2L V8 engine began shaking violently. The vehicle lost oil pressure, warning messages appeared on the dashboard, and the vehicle completely lost propulsion and shut down while still in motion. My spouse and child were inside the vehicle. The sudden loss of power at highway speed created a serious risk of a collision, although I was able to bring the vehicle to safety. No collision, bodily injury, fire, or property damage occurred during this incident. An OnStar/Cadillac notification reported a critical engine and transmission system problem and diagnostic trouble code P0016. The vehicle was towed directly to an authorized Cadillac dealership. The dealership opened the repair order on June 15, 2026, at approximately 46,640 miles. The dealership determined that the vehicle required a replacement engine. The replacement engine later arrived, but additional required parts, including a seal kit and gasket, were still outstanding. General Motors advised in writing that there was no estimated arrival date for those parts and no confirmed repair-completion date. The vehicle and failed engine components have been in the possession of the authorized Cadillac dealership and should be available for inspection. General Motors confirmed that the engine failure and repairs are covered under warranty. I am reporting this incident because the engine failure caused a complete and unexpected loss of propulsion at highway speed, placing the vehicle occupants and surrounding motorists at risk.

After accelerating from a stop sign to about 60mph on a 2 lane road, the engine shut off and the vehicle changed to neutral. I had to glide the truck down the road and off to the side. Vehicle would not start and had to be towed to a Cadillac dealership on a flatbed.

Driving on the freeway at 70mph, vehicle lost power and slowed down with no warning. Gas pedal unresponsive. Received message on screen to start vehicle. was able to swerve to shoulder lane out of oncoming traffic's way just in time for it to come to a full stop and never start again. When attempted to start vehicle again, it was completely unresponsive. Had to call for police escort since car was in near path of oncoming traffic. Tow truck had to haul to dealership location near home (100+ miles away). Currently still receiving alerts from onstar that all vehicle functions are clear and OK with no issues "green checkmark" on all components. No recalls or service issues in the vehicle for 22k miles until failure.

On Sunday April 19th at approximately 12:00pm. I was driving on NJ’s garden state parkway when the car had catastrophic engine failure at highway speeds. I lost full power, including power steering, and brakes. This SUV could have killed my family and I if I was unable to use brute force to control it into the right lane. While I understand that any vehicle can experience warranty-related issues, a catastrophic engine failure at highway speeds is not a typical or acceptable occurrence. The severity of this incident has significantly impacted my confidence in both the vehicle and the brand. I am particularly concerned about the safety implications associated with the L87 6.2L V8 engine, which has been widely reported as affecting a substantial number of vehicles. Given what occurred, I no longer feel safe operating this Escalade. My wife is unwilling to drive it, and I am not comfortable having my child in the vehicle under any circumstances.

ENGINE,FUEL/PROPULSION SYSTEM03/19/2026
After having the initial engine failure recall completed by the dealership by switching to a different viscosity oil… While traveling at 45 mph the motor made a knocking or ticking sound with a squeal and then “hiccuped “ and immediately lost all power. I was only able to steer the vehicle onto a busy sidestreet. The vehicle had recently been serviced by Cadillac. Once stopped, the vehicle cannot be shifted from park due to “shifting conditions not met” so I was blocking the entire intersection. Police had to respond for traffic control. Due to the electronic shifter the only way to shift the vehicle into neutral is with tools and getting underneath the vehicle to remove a bolt. There is no reasonable or prudent way to do this in the middle of an intersection.

Traveling on interstate preparing to exit on ramp. Press start button displayed, car immediately sounded like it geared down hard and then lost power, unable to control well, all I could do to come to a safe stop, while praying that the car behind me didn’t hit me. The car basically locked up while preparing to exit the interstate. So scary, terrifying and dangerous.

Component/System Involved: Engine / Powertrain and Vehicle Electronic Control Systems, including Serial Data Gateway Module Description of Failure: While driving at highway speed (approximately 60 mph), the vehicle experienced a sudden and complete loss of propulsion without warning. Engine power was lost while traveling on an interstate, forcing me to pull onto the shoulder without propulsion. The loss-of-power event occurred more than once during the same trip. The vehicle was towed to an authorized Cadillac dealership for inspection. Dealer diagnosis confirmed internal mechanical engine failure, including metal debris present in the engine oil, requiring full engine replacement. During diagnostic procedures, the dealership also identified electrical communication faults involving the serial data gateway module, including voltage fluctuation and wiring chafing within the vehicle harness. These faults caused loss-of-communication conditions between control modules and required repair. Safety Risk: The loss of propulsion occurred at highway speed with passengers present in the vehicle, creating a serious safety hazard. Sudden power loss on an interstate increased the risk of collision due to the inability to maintain speed or maneuver safely in traffic. Confirmation / Inspection: The failure was confirmed by an authorized Cadillac dealership. The engine was removed and replaced due to internal damage. Electrical communication faults related to the serial data gateway module were also confirmed and repaired. Warning Indicators: No warning lamps or alerts were displayed prior to the loss of propulsion. Communication faults were identified during post-failure diagnostics. Current Status: The vehicle has undergone engine replacement and electronic repairs and is currently under post-repair monitoring due to the severity and safety implications of the failure. Availability for Inspection: The vehicle and repair documentation should be available through dealership

The check engine light has been coming on intermittently and the engine has felt rough operating. On December 23, 2025, despite the absence of an illuminated "Check Engine Light", I was driving the vehicle when it suddenly lost power/acceleration in the middle of a busy street, which caused me to nearly get into an accident. I brought the vehicle into the Dealership on 12/29/25, and is still there as of 1/7/26. The Dealership has hooked my car up to the scanner, which found code P0300, and they indicated that it's showing a history of misfires across all cylinders. The Dealership has said that they cannot fix the car because they cannot get the Engine Light to illuminate and because as of 1/7/26, my VIN is not included in part of the widespread Engine recall. My vehicle poses an extreme safety risk to drive, and I do not feel comfortable driving it, knowing that the Engine is misfiring and could lose acceleration or power at any moment and without warning.
