2023 Cadillac Escalade: excessive oil consumption

Filed Aug 31, 2026 · Driver assistance, Engine · NC

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.

Their answer was if the engine fails AGAIN the vehicle is under warranty. The engine oil continues to be full of metal chunks. In my opinion metal in oil is engine failure.
