There is a reaccuring safety defect issue where the engine completely shutts off and stalls without warning when the car comes to a stop.

Heard a knocking noise in the engine, had it serviced at an independent mechanic (towed as to not create more damage and the knocking noise was louder). Mechanic told me that the rod bearing/engine had failed and would need to be replaced. $7000-$10000 for replacement. He also indicated that this was under recall for 2016-2020 cars. I checked my VIN and my car is not part of the recall but the car has 130000 miles and has been serviced regularly. I am requesting that it be part of the recall since this is a known/reported issue for this year/model. I called American Honda and they said because of the mileage and age, that it would not be part of the recall.

"My 2016 Acura MDX completely seized on the highway after a loud knocking sound, which perfectly matches the connecting rod bearing failure under Recall 23V-751. Even if my specific VIN isn't showing up as open on the website, I know the NHTSA has a major open investigation into 1.4 million of these V6 engines because hundreds of vehicles are failing exactly like mine outside the original recall scope. I need Acura to open a corporate goodwill case to inspect my engine and cover this repair."

The issue is with all 2016-2025 Acura Mdx models that have the 3.5 v6 in it .

I was driving on the highway. All of a sudden, my engine started making knocking noises. Shortly after that, the car started to lose power, and immediately the low engine oil light came on.

When driving at highway speeds there randomly is a full loss of engine power for 3 to 5 seconds. Each time this has occurred I was on the highway and depressing the gas pedal further to either pass another car or because I'm driving up and incline. For several seconds the car looses all power and begins slowing. Traffic approaching rom behind may have to apply brakes.
