Consumer Description

On Aug 8th at 3:32pm (81F and sunny), I stopped at a red light with the auto idle engine feature on. When I lifted my foot off the brake to drive the car, the car shifted into neutral and completely shut down and would not restart immediately. I attempted approximately 8 times to restart the car for 3 minutes before it successfully restarted. This poses a significant safety hazard for myself, my children, and others on the road. This is the 6th time this has happened and I have previously filed a NHTSA report # 11533671 with the same issue. Acura has been unable to diagnose and recreate the problem and is refusing to do any further work. It has been brought into their dealership on 3 separate occasions (July 2023, September 2024, August 2025). Prior to this occurring, there were no warning symbols, the car started fine without issue, and the battery has been checked and confirmed in working order.
