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.

On 06/23/2026 at approximately 62,745 miles, I brought my 2023 Cadillac Escalade Sport Platinum 4WD equipped with the 6.2L L87 V8 engine to a Cadillac dealership because of excessive engine oil consumption. The vehicle has been consuming approximately 3 quarts of engine oil every 2,000 miles, or roughly 1 quart every 650-700 miles. The dealership began an oil-consumption test to document the condition, and the vehicle is currently still at the dealership undergoing evaluation. This vehicle is equipped with the 6.2L L87 engine involved in NHTSA Safety Recall 25V-274 / GM Recall N252494000 concerning internal engine damage and possible loss of propulsion. I do not know whether the excessive oil consumption is directly related to the recall defect, but I am concerned that this level of oil consumption may indicate an internal engine problem that could lead to inadequate lubrication, engine damage, stalling, seizure, or sudden loss of propulsion. The vehicle is available for inspection at the Cadillac dealership. The dealer has service records and oil-consumption-test documentation associated with this condition. I am filing this complaint so the excessive oil consumption on this L87-equipped vehicle is formally documented with NHTSA and can be considered along with other reported L87 engine concerns.

The engine/powertrain malfunctioned on my 2023 Cadillac Escalade at approximately 29,434 miles, ultimately requiring complete engine replacement. During the engine repair, the Cadillac technician also discovered that the transmission cooler lines were leaking fluid. The dealership replaced all of the affected transmission cooler lines as part of the repair.The original failed engine was removed by the Cadillac dealership, so I do not know whether GM/Cadillac retained it. The failure involved the vehicle’s engine and created concern about the possibility of sudden loss of propulsion or engine failure while driving. Because this is a large vehicle routinely operated on public roads and highways, an unexpected loss of engine power could significantly reduce my ability to safely accelerate, merge, or move the vehicle out of traffic. Fortunately, I brought the vehicle in for service after noticing the abnormal engine noise before a complete failure occurred while driving. Yes. Heritage Cadillac inspected and diagnosed the vehicle. The dealership documented my complaint of a “weird noise on start up” that continued until approximately 10 MPH. The technician removed the valve covers and inspected the rocker arms and pushrods. The dealership ultimately determined that an engine replacement was necessary and replaced the engine under warranty. Yes. The vehicle was inspected and repaired by Heritage Cadillac, an authorized Cadillac dealership. The dealership diagnosed the engine issue and replaced the complete engine. During the repair process, the technician also discovered leaking transmission cooler lines. I did not receive a warning lamp or dashboard message alerting me to an engine problem. The primary symptom was an abnormal engine noise shortly after startup that continued during initial acceleration to approximately 10 MPH. This prompted me to bring the vehicle to Heritage Cadillac for inspection. The dealer documented this symptom on the repair order.

I was driving and the vehicle stopped accelerating and the gear was in neutral. I pulled over and turned the car off then attempted to turn it on, but it would not turn over. All electrical was on, but the car would not start. This same thing happened two days prior twice within 10 min. of each other, but I was able to start the car those times. Due to the speed suddenly declining and being unable to accelerate on a two lane road with cars behind me; it could have caused a serious accident. It has not yet been confirmed by a dealer, but this is a known recall for this vehicle that was listed as complete prior. There was no warning lamps or messages prior to the failure. The first noted incident happened on 8/10/26.

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.
