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)

My 2021 Cadillac Escalade ESV with the 6.2L L87 engine received the remedy for Safety Recall 25V‑274 (GM recall number N252494001) on July 30, 2025. The dealer inspected the engine, passed it, and performed the higher viscosity oil remedy. The engine was not repaired or replaced. On [DATE], while driving, the vehicle hesitated and lost power under acceleration. Engine noise then increased progressively until I pulled over on the side of the road. The engine stopped running and would not restart. The dash displayed a message to press the start button again. The check engine light illuminated at the time of failure. There were no warning lights prior to that day. My family, including my children, were in the vehicle when it lost power. We were stranded on the roadside until the vehicle could be towed. The battery and electrical system are functioning normally, but the engine would not start. The vehicle was towed to a Cadillac dealership. At the dealership, a start attempt produced a loud knocking noise from the engine along with a fuel/oil odor. I believe the connecting rod bearings have failed. These symptoms — hesitation, loss of power, and knocking noise — are the exact pre-failure indicators GM identified in Recall 25V‑274. This was a loss of motive power while driving on a public roadway, creating a serious crash risk for my family and surrounding traffic. The recall remedy performed on this vehicle was inadequate. GM inspected this engine, passed it, and it failed approximately one year later in exactly the manner the recall was intended to prevent. Date of incident: 08/08/2026 Mileage at failure: 66,000 Recall remedy completed: July 30, 2025 Vehicle was towed. No crash, fire, or injury occurred.

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.

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.

My wife was driving my kids to their nana and papas house when the vehicle loss power. The vehicle started to have a knocking noise and started to vibrate towards the engine compartment. The dash lit up like a Christmas tree. We took the vehicle to a local mechanic and he suggested that we might need a tune up. We purchased 8 brand new spark plugs, spark plug wires and 8 brand new coil packs. The local mechanic installed all of the new parts and the vehicle acted just like it was before the tune up. We then took the vehicle to Boyd Cadillac in Henderson,NC. Tim, who is our service provider, contacted us and told us that we had severe engine failure. His recommendation was a complete engine install. We have used Boyd Cadillac, Tim on several occasions. We had an alternator replacement done which was not under warranty. We had lifters replaced under warranty around the 50k mile mark.
