NHTSA Complaint #11715994 — 2021 CADILLAC ESCALADE ESV

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.
