   The car had several warnings lights come on and immediately stalled out and stoped right in the middle of the road. The engine would turn over but would sputter like it was out of gas and would die after a few seconds. It stoped in the middle of a busy state highway in a curve. Luckily no one got hurt. I towed it to an auto service center. The 2020 Acura MDX suffered an in-tank fuel pump failure causing a low fuel pressure code (P0087). This model year is under a massive…

   While driving my 2020 Acura MDX A-Spec at approximately 63,744 miles, the vehicle suddenly lost all engine power without warning while passing through a busy multi-lane intersection. The loss of propulsion prevented acceleration and forced us to coast across traffic lanes to reach the shoulder, creating a significant safety hazard. The engine would not restart. The vehicle was inspected on 3/17/2026 by Lyle Pearson Acura (Boise, ID). The dealership diagnosed catastrophic…

   Auto idle cuts off idling at stop light but when reengaged stalls the car completely. Must totally restart car before continuing causing back up in intersection and almost being hit. Happened several times, when I forget to turn auto idle off. New battery did not help

   When the vehicle stops and the idle auto-start/ stop engages, the vehicle will automatically go into neutral and cannot be restarted until the vehicle is turned off then back on. This has happened at both stop lights and on the highway and almost caused a very serious rear end accident.

   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…

   I am writing to formally express my concern regarding a recurring issue with the Auto Start/Stop feature in my 2020 Acura MDX. This feature, which is intended to improve fuel efficiency, has instead caused unexpected and unsafe engine shutoffs while the vehicle is in operation. On multiple occasions, the vehicle has failed to restart promptly after the engine shuts off at a stoplight or in traffic, creating a serious safety hazard. The delay or failure to restart can leave…

   My car has been going into neutral when in the autostop. The only way to get out of it is to turn it off and back on. It's incredibly dangerous. I almost got into a horrible accident. It happens suddenly and without warning.

   When using the a/c while the Auto Idle Stop is engaged, the engine will shut off and not restart. This issue does not happen immediately, at the first cycle of being activated, it's after 3 or more cycles of the AIS being in use, like driving in stop and go traffic for instance. The issue reminds me of a low/dying battery when it happens. Now when I turn off the A/C, the car starts right up like normal. Also if I don't use the A/C, the AIS cycles like normal, like in…

    Auto Idle Mode - After we've stopped and released the brake to go forward, the car will then shift to neutral by itself instead of restarting to drive. This has happened frequently and is now starting to happen more often. This is a safety issue, especially if you're the last car in line and other cars are traveling 55-60 miles behind you on a major road and see a green light ahead. Each time this happens, we have to turn off the car and try to restart the car, and sometimes…
