NHTSA Complaint #11702666 — 2025 ACURA MDX

The idle-stop function would frequently malfunction. I would be at a stop, which would trigger the idle-stop function and the car would turn off, but when I released my foot off the break in preparation for needing to start moving, the car would stall and shut completely off. There was about a five second delay before I could get the car to turn back on and start moving, which was very scary with traffic all around me. After the malfunction occurred several times, I would try to remember to turn off the idle-stop function using dynamic mode. I called my local Acura dealership about this problem and the service manager said that he wasn’t sure what was wrong nor did he know how to fix it. He advised me to just wait and hope that Acura issues a recall for the issue. Then, I started noticing that there was a delay in my vehicle starting when pressing the start button. It wasn’t too long of a delay but enough for me to notice. Since the car would ultimately start, I didn’t think too much about it, until my car failed to turn on. It has happened when I turn off my car but then need to turn it back on soon after turning it off. I’ll press the start button and the lights on the dash come on and I can hear the engine trying to turn on but it doesn’t. The engine won’t crank up. I have to let it sit for a few seconds (30 sec?) and then try to turn it on again, at which time I have been lucky that it will turn on, but the initial start-up sounds like a struggle. It doesn’t sound like a healthy start up for 2025 vehicle.
