2024 Cadillac Escalade Powertrain (other) Problems

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.

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).

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

While driving on a major highway and traveling at 80 mph or so, the vehicle flashed a warning light saying “Press Start Again.” I noticed the gas pedal was no longer responding and the RPM gauge dropped to zero. The vehicle shifted itself into neutral and I was forced to steer the truck to a shoulder and scraped the underside of the front ground effect trim. The vehicle then shifted into park and would not start. When a tow operator arrived, the vehicle could not be shifted into neutral to be towed and the electric parking brake kept activating by itself while trying to load and unload the vehicle from the flatbed. The vehicle is now completely immobile and I’m waiting for information from the dealership.
