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)

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 the federal safety agency 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 the federal safety agency and can be considered along with other reported L87 engine concerns.

Purchased the vehicle 1 year ago and immediately it had oil consumption problems. Got low oil alarm after 2000 miles from the dealers oil change. Dealer told us it was within “specs”. 6 months ago we were told the 6.2 engine had a recall and a different type oil will be used. 1 month ago the engine locked up and it is now at the dealer waiting for an engine. Asked another car dealership about trading it in and they would not accept it as a trade-in because it currently has a stop sale issued. This means the vehicle is now worth nothing! Well, I have to hire Attorney to get anything for this vehicle? We paid $75,000 for it a year ago

While driving my 2021 Cadillac Escalade on an interstate highway at approximately 70 mph with my family, including two minor children, the vehicle suddenly and without warning lost propulsion, shut off, and shifted into neutral. This occurred in active traffic and created an immediate safety hazard. A warning message appeared instructing me to restart the vehicle. After several minutes navigating traffic, I was able to restart the vehicle briefly and exit the highway. Shortly thereafter, additional dashboard alerts appeared indicating critical engine and transmission failure. After exiting the highway, the vehicle shut down completely at a traffic signal and failed to restart. The vehicle was immobilized in an active roadway until police assistance arrived to prevent a rear‑end collision and a flatbed tow was arranged. The sudden loss of propulsion at highway speed placed vehicle occupants and surrounding motorists at serious risk. The vehicle is available for inspection and was diagnosed as having a seized engine on March 9, 2026, by Diamond Cadillac in [XXX] . This failure did not occur without warning. Prior to this incident, I repeatedly reported excessive oil consumption to the selling dealer, Otto Cadillac, from whom I purchased the vehicle in April 2025 as a Certified Pre-Owned vehicle. On two separate service visits, I reported oil consumption exceeding two quarts between recommended service intervals and requested that this be documented. I was advised that the consumption was “within tolerance” and was later informed—incorrectly—that this tolerance applied to my engine configuration. Otto Cadillac performed a recall-related inspection and implemented the manufacturer-directed remedy consisting of an oil cap replacement and a change in oil viscosity to SAE 40. No mechanical repair or deeper diagnostic action was taken. The subsequent engine seizure confirms that these mitigation measures did not resolve the underlying defect.
