“My 2025 Acura MDX completely stalled in active roadway traffic and failed to restart. The failure occurred during a routine stop in traffic, tied to the Auto Idle-Stop / restart sequence: when releasing the brake pedal to accelerate, the engine did not restart, leaving the vehicle completely dead and stranded in the travel lane, creating a severe risk of a rear-end collision. I brought the vehicle to an authorized Acura dealership for repair. The dealership diagnosed the issue and replaced the starter motor under warranty. …”
NHTSA complaint #11767195, filed 2026-09“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. Please consider investigating this matter further as I am concerned for my safety and the safety of my passengers.”
NHTSA complaint #11678817, filed 2025-08“The auto shutoff and restart system has failed multiple times causing the car to shutoff in the middle of traffic. This has happened in traffic on the interstate, on surface streets and in the drive thru line. Safety was put at risk as had to restart car in middle of traffic multiple times; once car would not restart at stop light. This could have caused an accident as vehicle was at a full stop with cars coming up from behind in the road. Dealer has replaced starter and relay twice. In less than 2 years, I'm on my third starter. Dealer has inspected vehicle multiple times. …”
