2023 Cadillac Escalade

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. Additionally, ODI has received 191 reports of L87 engine failures in engines produced after the production period cited in Recall 25V-274. GM reported receiving 6,953 complaints of post-remedy engine failure. ODI is opening this Engineering Analysisto continue investigating complaints of post-remedy engine failure. ODI is expanding the scope of this Investigation to include engines produced after the production period cited in the recall. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024.  GM cited the root cause as a supplier manufacturing and quality issues. GM’s  recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).

Prior to purchasing my 2023 Cadillac Escalade, I was informed the vehicle had been subject to an engine recall. The dealership told me the corrective action was changing the oil from 0W-20 to 0W-40, replacing the filter, and updating the oil cap. I was assured this resolved the issue and that I should not experience future problems. Based on those assurances, I purchased the vehicle in October 2025 with approximately 25,000 miles. About nine months later, the engine shut off while I was stopped at a traffic light. The vehicle automatically shifted into neutral and turned off. I restarted it and continued driving. The exact same incident occurred again a few days later. I brought the vehicle to a Cadillac dealership for inspection. After several hours of diagnostics, I was told they could not find any issues and that the vehicle appeared to be operating normally. Two days later, while traveling approximately 75 mph on the highway with my family, including two young children, a warning message appeared instructing me to restart the vehicle. At the same time, the vehicle shifted into neutral and lost propulsion. I pulled to the shoulder and restarted the engine, which struggled to start and ran very rough. After resuming travel, the exact same failure occurred again within minutes at highway speed, forcing me to pull over a second time. Concerned for my family's safety, I exited the highway and drove local roads. The vehicle was returned to the dealership. An oil sample was sent to a GM-approved laboratory, and I was later informed that elevated levels of metal contamination were found in the oil. GM subsequently authorized a complete engine replacement. I am submitting this complaint because the recall remedy I was told would resolve the issue did not prevent a major engine failure. The vehicle shut off twice at stoplights, passed a dealership inspection, and then lost propulsion twice at highway speeds. This presented a significant safety risk to my family and

I am reporting ongoing safety concerns with my 2023 Cadillac Escalade involving unexpected acceleration and loss of propulsion while driving. On XXX, while traveling to [XXX] in slow-moving traffic with Super Cruise engaged, my vehicle unexpectedly accelerated forward. I immediately applied the brakes to avoid striking the vehicle ahead. I reported the incident to the Cadillac dealership and contacted OnStar. OnStar records reflected the acceleration/hard-braking event, but the dealership could not identify the cause. On XXX, the vehicle experienced a significant loss of engine/transmission power while I was driving. I contacted OnStar, which reported transmission control module-related diagnostic codes P0747 and P0700 and indicated reduced power/transmission malfunction. I had difficulty reaching a safe location and the vehicle was ultimately towed to a Cadillac dealership. I have also experienced ongoing excessive oil consumption. I first reported this in May 2024 at approximately 21,000 miles. Multiple oil consumption tests were performed, but I repeatedly had to add oil between changes. In June 2026, the vehicle displayed an “Add Oil” warning even though the oil life monitor showed approximately 37% remaining. The vehicle has also had recurring HVAC problems requiring multiple dealership visits, including a coolant flush for an air pocket and later vent actuator recalibration. The vehicle has been inspected and serviced by authorized GM/Cadillac dealerships multiple times, including recall work, oil consumption testing, powertrain diagnosis and HVAC repairs. Despite these repeated visits, concerns continue. My primary safety concerns are the unexpected acceleration and subsequent loss of propulsion/reduced power while driving. I am reporting these incidents because they may indicate a safety-related defect. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was driving down the road, doing approximately 50 mph, when my vehicle shifted itself into neutral and I lost power completely. The information center said "reduced power. Press the start button to regain power," which I did, but nothing happened. I had to pull off the road and have my vehicle towed to a Cadillac dealership in Lima, OH. The dealer, Lima Auto Mall, confirmed I suffered a complete engine failure. This is one of the 6.2L engines that GM has recalled and I had already had the engine inspected by my local Cadillac dealer and they told me my engine was "good," and switched to the 0W40 motor oil. I had just had the vehicle into my Cadillac dealer 4 days prior where they performed an oil change, tire rotation, 80,000 mile service , etc. Four days later, the motor completely failed and had to be replaced.

Re: 2023 Cadillac Escalade 6.2L Engine Recall and Safety Concern. I followed the recall process, had the prescribed remedy performed, and yet the information now available has left me with substantially diminished confidence that the vehicle is protected against the very failure the recall was intended to address (catastrophic engine failure). My concern is reinforced by NHTSA's Engineering Analysis EA26005, which is examining post-remedy engine failures. When cold starting my Escalade, I hear clanging, flapping, and what I perceive to be abnormal noises coming from the engine. Combined with documented post remedy failures now being investigated by NHTSA, I do not believe the recall remedy provides a sufficient margin of safety.
