2023 Cadillac Escalade ESV Speed Control & Cruise Problems

While driving my 2023 Cadillac Escalade (approx. 42,308 miles), the vehicle experienced a sudden and complete loss of power while accelerating on a busy highway. Engine power shut down without warning. I was able to pull to the shoulder, but the vehicle then became non-responsive and would not restart. The failure appears related to the electrical/charging system (12V battery, battery management system, alternator, or related modules). The vehicle is available for inspection upon request. This failure placed my family and others at serious risk. The loss of propulsion occurred in traffic, creating a collision hazard. After stopping, the vehicle had no heat and limited power while unable to start leaving us stranded on the shoulder of a heavily traveled highway in 10-degree weather. My two toddlers were in the vehicle, creating additional risk from traffic exposure and cold. This was a repeat incident. Approximately two weeks earlier, the vehicle experienced a similar power loss. A Cadillac dealership replaced the 12V battery and stated the issue was resolved. However, on January 22, 2026, I contacted the dealership and provided a video showing abnormal starting behavior, indicating the problem may not have been fixed. I followed up by phone the next day but received no response. Despite this prior repair and warning, the same failure occurred again. There were no clear warning lights or messages immediately prior to the power loss. After the failure, the vehicle was unable to restart. I also attempted to use OnStar, a paid emergency service, but was placed on hold for approximately 30 minutes. Due to unsafe conditions, my wife had to come pick us up to remove our children from danger. This incident involves a repeat loss of power while driving, prior warning signs, and failure of emergency support systems, raising serious safety concerns.
