Stalling on other MDX years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2018, 2022.
What this problem usually is
Stalling reports are some of the most alarming on the site. The engine quits while the car is moving, sometimes on a highway and sometimes at a stop. Many owners say it restarted right away and the dealer found no stored code, which is part of why these complaints pile up before anything gets fixed.
What got replaced
Owners who name the part that was replaced mention the battery (9 reports).

“the car shuts off at a red light, fails to auto-restart, forces the car into Park, and requires a full manual reboot or jumpstart while stuck in moving traffic. It also struggles to turn on at times mimicking a drained battery. I am needing to deactivate the auto start/stop feature in order for the vehicle to properly function. Vehicle will not start when parked at times.”

“The auto idle stop feature will kick in at red lights, shutting the engine down. However, every approximate 1 out of 10 times the engine and electrical system fully shut down when I try to start the car moving again. The car can then not be restarted for close to a minute. This results in not being able to move when the light turns green and is dangerous is heavy traffic areas.”

Should you keep driving it?
This page can't tell you that. 0 of 48 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
