Owner report 11636296 · 2025-01-16 (January 16, 2025)
My new Acura MDX has very soft braking under normal braking and with harder braking the pedal normally is at the same level as the accelerator pedal which I feel could be a safety issue if your foot is then pressing both pedals at the same time. Also, when driving with adaptive cruise activated, when the car starts to brake on its own following another slower car, with my foot resting on the accelerator, the brake petal will activate and sometimes trap my foot between brake and accelerator petals. This is new to Acura as this is my third MDX si…

Owner report 11694662 · 2025-10-21 (October 21, 2025)
Car engine sometimes does not restart when the auto start-stop feature is engaged. Car engine is also sluggish to restart when it does work. My local Acura dealer evaluated the car on 10/15/25, found battery was low. Battery was replaced that day, and things seemed okay for about a week. Today (10/21) when I was stopped at a traffic light, the issue returned and my car would not restart after going into auto start-stop. The car had been on for about 30 minutes. When I tried to restart the engine, it took three tries before finally turning over.…

Owner report 11696289 · 2025-10-29 (October 29, 2025)
When the automatic engine start/stop is enabled, my car will shut down. To the point where it has to be completely off, then restarted. This has happened twice, the first time was on 9/28/2025 and the second time was on 10/29/2025. We were in traffic, and the car behind me, almost ran into me, as I stalled. the lighted symbols on the dashboard were illuminated during this experience, but I am not sure which ones, as I was in a panicked state given that my child was in the car with me and this almost caused me to get hit by car behind me. I hav…

Owner report 11693356 · 2025-10-14 (October 14, 2025)
My 2025 Acura MDX randomly turns off when in Auto Stop/Start mode at stoplights and I have to restart it. After it happen twice, my husband took it to the dealer, and they could not find anything wrong with it. It happened a third time and this time the dealer kept it for a week. They found nothing so their system doesn't detect problems well. I had their loaner, a 2025 MDX A-Spec. I was driving the vehicle into a parking space at my office which faces a 4-lane highway. My foot was on the brake, and I was 2/3rds into the space. Suddenly the ca…
