This is a third occurrence related to NHTSA complaints 11749893 and 11750183. On July 15, 2026, at approximately 7:30-7:42 AM, while driving to a scheduled Ford service appointment, the vehicle exhibited hesitation and delayed acceleration at multiple intersections, not isolated to one location. Although the vehicle's auto start-stop feature has been manually disabled, the hesitation at each stop felt similar to that feature engaging and re-engaging the engine. The vehicle then stalled completely at an intersection and would not move for approximately 10 minutes. The check engine light illuminated for the first time during this incident. Kent Police Department was contacted, event number 2026-44221. The vehicle was subsequently dropped off at a Ford dealership on July 15, 2026 for diagnosis under warranty.

Incident

Jul 13, 2026

While driving home and stopped at a red light, the dashboard displayed a "Service Required" warning followed immediately by a "Shift System Fault" message. The vehicle would not accelerate and stalled in the middle of the road with traffic going around me. I was unable to move the vehicle until I was able to restart it, which took at minimum 2 tries and 5 minutes. The warning cleared after restarting but the vehicle had been purchased 11 days prior with only 18,241 miles. The problem has not yet been confirmed by a dealer but I am scheduled to take it in for inspection. No prior warning lamps appeared before this incident. The vehicle is available for inspection upon request.
