2021 Cadillac Escalade ESV: engine failure

Filed Oct 7, 2026 · Engine · FL

My 2021 Cadillac Escalade ESV (VIN [XXX]) developed an engine failure after receiving the recall remedy for the federal safety agency recall 25V‑274 (GM 6.2L V8 connecting rod/crankshaft defect). Symptoms: engine misfiring, dashboard warning lights illuminated, engine stalling/misfiring at idle, loss of power on acceleration, and a valve-like knocking noise coming from the engine. The loss of power and stalling while driving put my safety and the safety of others at risk. The vehicle is currently at the Vera Cruz Cadillac dealership, where it has been sitting for almost a month while awaiting the warranty process. The dealer has not confirmed the root cause. This engine failure occurred AFTER the 25V‑274 recall remedy was completed on this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On XXX I had been driving my vehicle with no issues. I had drove from [XXX] to [XXX]. My vehicle had no warnings or issues prior and my vehicle has been properly cared for and all oil and maintenance has been done through the Cadillac dealership in [XXX]. On my way to [XXX] I stopped at the local gas station and filled my gas tank fully up, when I started my vehicle there was a horrible sound and my car began to shake and all the electronics began coming up. I went to work less than 5 minutes down the road and the vehicle was horrible acting. I called my husband and began thinking maybe I had put bad gas in the vehicle because like i mentioned earlier there was nothing wrong with my vehicle prior to this. We contacted the dealership in [XXX] and they told us to bring the vehicle in, I had to drive my car back to [XXX] where i was petrified my vehicle was going to blow up or just die in the road. I made it to the dealership and explained what happened and that i thought it was bad gas, they let me know they would look at the vehicle and let us know. They contacted my husband later in the day and let him know the good news was that it was not bad gas, unfortunately my engine blew up. He said my engine has done what the recall engines have been doing, unfortunately my vehicle is not in the recall and that it would be $12,000.00 to fix it. When my husband called me, I had him three way the dealership and explained we have taken very good care of our vehicle with all maintenance and oil changes done there. He explained to me that it was nothing we could have done and i wanted to know why then the engine blew without warning and he continued to explain it was like the other vehicles in a recall. He kindly explained that there was nothing he could do but we could try and contact GM if we could get ahold of them and we could file a complaint reguarding our vehicle.

2021 Cadillac Escalade ESV equipped with L87 6.2L V8, subject to the federal safety agency Recall 25V‑274 / GM N252494000. The recall inspection was completed and the vehicle passed, so GM performed the 0W-40 higher-viscosity-oil remedy rather than engine replacement. The vehicle has a history of unexplained oil loss with no obvious external leak, including a prior low-oil warning. At a recent oil change after approximately 5,000 miles, no oil registered on the dipstick before service. The engine was then filled to the full mark. Using the same repeatable checking method, the level was approximately 3/4 at 227 miles and approximately 1/2 at 1,300 miles. I am concerned that a progressive internal engine condition may not have been detected by the recall inspection and that the oil-only remedy may be inadequate. the federal safety agency currently has Recall Query RQ26001 open regarding engine failures after Recall 25V‑274 remedies. I am also concerned because GM Special Coverage N252494003 excludes an engine presenting with low/no oil as neglect even if unresolved mechanical oil consumption caused the low level. I am requesting this complaint be associated with Recall 25V‑274 and RQ26001. Please advise. I just bought the car less than a year ago and can’t a new engine.

I purchased a 2021 Cadillac Escalade ESV and shortly thereafter experienced an engine malfunction. The vehicle developed a misfire, rough idle, loss of power, and produced significant blue/white exhaust smoke. The check engine light illuminated and the vehicle began running abnormally. An independent repair facility inspected the vehicle and reported oil-related issues affecting a cylinder and spark plug. The repair facility also observed excessive exhaust smoke during diagnosis. The condition raises concerns about potential engine failure while driving, which could result in loss of power and create a safety hazard in traffic. The vehicle is currently undergoing diagnostic testing, including a leak-down test, to determine the cause of the failure. The problem has been confirmed by a repair facility and occurred shortly after purchase.

I purchased a used 2021 Cadillac Escalade in May 2025 with approximately 48,000 miles. While driving on Highway 14 near Acton CA at speeds exceeding 60 mph, the vehicle experienced a catastrophic engine failure (March 28th - 2026). The engine suddenly lost all power and shut off completely while in motion. Only electrical systems remained operational. At the time of the incident, I had my three children in the vehicle. This created a dangerous situation, as I was forced to maneuver across traffic and safely pull over without engine power. The vehicle could not be restarted and had to be towed to the dealership. The dealership replaced the engine with a refurbished unit April 14th - 2026. I was not informed in advance that the replacement engine would be refurbished rather than new. Immediately following the engine replacement, the vehicle began experiencing additional issues, including electrical malfunctions and air suspension problems, which required further repairs. After retrieving the vehicle, it is still not operating as expected. The vehicle is noticeably slow, sluggish, and noisy, raising concerns about reliability and the potential for another failure. Given the sudden loss of engine power at highway speed and the continued performance issues after repair, I have serious concerns about the safety of this vehicle.

The check engine and several other unknown warning lights were illuminated. Additionally, the contact stated that the engine consumed an excessive amount of oil and that engine oil was added every two to three weeks. The contact pulled over and had the vehicle towed to the dealer. The dealer informed the contact that because the vehicle was used as a limousine, the engine was consuming more oil than was normal.

The failure mileage was approximately 100,000.

My 2021 Cadillac experienced a catastrophic engine failure that is mechanically identical to a known GM engine defect currently under recall. GM has denied coverage solely because my VIN is not included, despite the failure matching recall symptoms and diagnostics. This defect caused sudden loss of vehicle use and presents a safety and financial risk. GM is excluding vehicles with identical failures from recall coverage based strictly on VIN rather than defect presence. I am requesting the federal safety agency review of recall scope and defect coverage.

On 12/18/2025 at approximately 73,097 miles, while driving on I-75 near Wildwood, Florida at about 75 mph, the vehicle experienced a sudden powertrain failure. The engine became seized/locked, the vehicle progressively lost power, and there were abnormal/loud mechanical noises. I was able to avoid a crash, but the event created a safety risk due to loss of propulsion at interstate speed. No accident occurred. The vehicle later received an engine replacement at Plaza Cadillac (Leesburg, FL). Dealer paperwork indicates completion on 01/07/2026, and the vehicle was returned to me on 02/02/2026. After the engine replacement, the vehicle displays safety-related warnings including: “Service Transmission Now – Unable to Shift Soon” “Service Electric Parking Brake” Because of these warnings, I am not driving the vehicle. The dealer plans to tow the vehicle in for inspection. In addition, the dealership has stated in writing that they typically clear diagnostic codes for test driving and that no post-repair/post-road-test diagnostic scan reports are saved or printed, meaning there may be limited retained documentation verifying that all modules were fault-free at release after the engine replacement. Cadillac case reference: Cadillac Care Center Service Request #88422536. I consent to sharing this complaint and vehicle details with the manufacturer.
