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 fuel pump (8 reports) and the battery (8 reports).

Is this a known problem?
The manufacturer has sent NHTSA 3 service bulletins or notices for the 2019 Acura MDX that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

What owners wrote
“My vehicle is showing identical symptoms to those described in recall 21V-215/23V-858 related to the fuel pump. Although my VIN is not listed in the recall, I would like to verify whether my fuel pump is part of the defective batch, as it is failing in the same way (e.g., loss of power, engine shutting off, hard starting when cold, etc.). Or please confirm if my car symptoms are related to different campaigns.”

“I was driving down the highway today at 70 mph and all the lights illuminated on my MDX. It began to struggle to keep speed and eventually shut down once I was on the service road. I was extremely scared and nervous that I was going to be involved in an accident or the car was going to blow up as it started bouncing up and down while I was still on the highway.”

Should you keep driving it?
This page can't tell you that. 1 of 35 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.
