My 2020 Acura MDX shuts down and shifts to Neutral while stopped with the auto shut off feature engaged. This happens intermittently and the only remedy is to shut the car off and restart. It only seems to occur when the auto shutoff feature is engaged.

The engine idle stop function is unreliable and often fails to restart the engine when the brake pedal is released. The vehicle will, suddenly and without notice, become inoperable and undrivable wherever it rests, whether at a red light or stop sign, in the middle of an intersection while making a left-hand turn, or on an entrance ramp to a highway, causing a dangerous situation for myself and other drivers. It takes several minutes to restart the engine and sometimes must be jump-started. The issue has been reported to my local dealership, and they said it is not covered.

(4/2021). While cruising on a 2 lane hwy the power went to zero. All I could do was coast to the shoulder. Restarted and was on the go. If I was passing another car and this happened when there was oncoming traffic I could had a head on collision. This occurred twice on the same 3 day vacation Another time (8/2022) While cruising at normal speed and acceleration in the passing lane on the interstate all of a sudden the power went zero. All I could do was coast into the median to get out of traffic. I didn-€™t have time to check for warning lights. Just restored the engine and all was fine. Totally scary and unsafe. Dealer says they-€™ve had no similar complaints. Only thing to do is have it checked but if can-€™t duplicate the problem or find a code nothing they can do Thinking of selling it due to not knowing what deadly situation I may be in when it reoccurs. Internet chats are saying it happens to others as well. Where is the recall that should exist?

My car was stopped at a light with idle auto on. The car shut off and switched into neutral with check engines lights on the dash. I was not able to switch the car to drive. I had to restart the car. This has happened twice in 2 weeks at busy intersections. I have brought the car to the dealership but they are unable to replicate. There was no prior warning lamps or signs prior to this happening.
