What owners wrote

The auto start/stop system failed to restart at a stop light. This was an issue on the older MDX and TLX vehicles with the 3.5L V6 which resulted in a large recall. The recall has not been extended to cover the 2025 MDX and the dealership is refusing to fix the issue or acknowledge it despite having a video to prove it occurred. Acura is knowingly selling these vehicles with a dangerous safety defect that will occur at random.

July 2025

The contact owns a 2025 Acura MDX. The contact stated that while driving approximately 30 MPH, the vehicle bucked for approximately 3-seconds before the vehicle stalled. The hazards were activated, the vehicle was turned off, and the contact waited before restarting the vehicle. While restarting the vehicle, several warning lights quickly flashed, and the vehicle failed to exceed 4 MPH while driving to the nearest parking lot. The vehicle was towed to the dealer, but was not diagnosed.
