2024 Cadillac Escalade: sudden loss of power

Filed Aug 31, 2026 · Electrical, Engine · FL

My 2024 Cadillac Escalade had the 6.2 v8 engine recall done in 6/25. I’ve put less than 8k miles on it since and just rolled 32400 miles total. While driving with my family in the car on 8/30 on the highway, it lost all power and just shut off while driving highway speeds. I was able to safely stop but very dangerous. Vehicle would not restart and had to be towed to dealer.

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). 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.

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.

See attached document for complaint. I am writing to you as a deeply concerned mother and consumer seeking urgent help with a danger ous and unresolved engine defect in my 2024 Cadillac E calade, which has been formally recalled under NHT A Campaign 25V‑274 (GM Recall 1 252494000). I purchased this vehicle in good faith, believing it would be a safe, reliable car to transport my three young children (age [XXX] , [XXX] , and [XXX] ). lnstead, the experience ha been frightening and exhau ting. The veh icle has suffered repeated engine issues, loss of power, and extended repair attempts - and despite the recall acknowledgment, there is till no available remedy or meaningful support from General Motors. For month , I ha e been unable to afely rely on the car 1 depend on every day. I have pent over a month col lectively without my vehicle and continue to live\ ith constant fear that the engine may fail while dri ing with my children in the car. Each time I tart the vehicle, 1 brace for the po sibi lity that it could suddenly lose propulsion in traffic i a terrifying thought for any parent. I have followed e ery step required under the, arranty and recall process, contacted the manufacturer, and recently issued a formal repurchase demand under California's ong-Beverly Con umer Warranty Act. GM has admitted the defect but continues to leave families like mine waiting indefinitely for a repair that doe not yet exi t. Tam pleading for your agency' immediate intervention and over ight to en ure that GM repurcha es my vehicle before tragedy strike . My family hould not be left driving an unsafe vehicle with known defects - especially when manufacturers had prior knowledge of these issues years before notifying the public. Plea e, I urge HTSA to reviev thi case and compel General Motors to take immediate, re ponsible action to resolve it. The fear and uncertainty this has caused are overwhelming. I should not have to choo e between my family' afety and my only mean of tran portation. Thank you for your time, attention, and

This commonly known defect with gm motors put my family at risk with the loss of power while trying to merge onto highway with cars traveling at highway speeds. There were no warning lights or any check engine lights that came on.

I started my Escalade and 5 minutes later I lost power which as the entire vehicle had no power. So I left it alone for an hour or so in my garage and I started up again and this time didn’t loose power. Everything appeared normal and working again. Than the next day I started it up and I had this popup message SD card has been removed press ok to exit navigation (when no SD card was removed). I also noticed that my backup camera, grid lines, or augmented reality has also intermittently not working on days. It sometimes works as normal and sometimes it does not. The message shows Service Augmented Reality System. The following next day, while I’m cruising on the highway the Escalade shifted into neutral when I was going 75 mph and had no mechanical power. So I pulled over stoped the vehicle and shut it off. Restarted after 15 minutes and it operated normally. I’m worried about Safety since it shifted to neutral at highway speed and lost mechanical power, along with other power issues which is extremely dangerous. This vehicle either is a lemon or there is a unknown manufacturing defect and in both cases needs to be replaced due to egregious safety concern.
