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.

Having it at four different dealers have not corrected the infotainment screen, adaptive cruise control phantom braking, electrical display issues such as ambient temperature, malfunctioning fuel gauge. Check engine notification was on, they seem to have corrected that, the next notification was service rear axle. Back up camera fails intermittently. I have had it to the dealer nine times, GM won't do a buy back I guess until they are sued. Also, dealer changed the oil to a thicker viscosity due to the engine recall. All the above ongoing for a full year.

I was driving on the expressway going 75mph in the middle lane when the vehicle said “press start button” and lost all propulsion. I started slowing down rapidly and was unable to get to the right lane as there were vehicles so I merged to the left lane and came to a stop narrowly missed by a speeding driver. The vehicle would not turn back on. I was in the left lane around 2:30pm with rush hour beginning. I did not feel safe waiting for a tow truck so was picked up by a coworker.

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. 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. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
