In owners' own words
My 2016 MDX has a fuel pump failure which has caused my MDX to stall and LED to problems with my fuel injectors.
We bought a new MDX 2016 and the car was acting very strange.the powertrain was off, 30000 miles engine was out in the middle of the road, noises everywhere.
Problem started with Check Engine light coming on, then going off, then coming on again followed by what seemed like all system failure lights getting reported.

Recalls for the 2016 Acura MDX: 7
The rear subframe may corrode at the suspension mounting points, which can result in rear suspension component failure. Failure of rear suspension components, such as the rear control arm, can cause a loss of vehicle handling and control, increasing the risk of a crash or injury.
Moisture may enter the tailgate lid light assembly and wiring harness, which can cause the interior and exterior lights to fail, including the lid lights, position lights, license plate lights and taillights. Vehicle lights that fail to illuminate can decrease visibility and increase the risk of a crash.
The fuel pump inside the fuel tank may fail. Fuel pump failure can cause an engine stall while driving, increasing the risk of a crash.
Due to a manufacturing error, the connecting rod bearing in the engine may wear and seize, damaging the engine. A damaged engine may run improperly or stall while driving, increasing the risk of a fire, crash, or injury.
Moisture may enter the tailgate lid lights, possibly causing a loss of the tailgate lid lights and the taillights. Loss of the taillights reduces the vehicle's visibility, increasing the risk of crash.
Particulates in fuel may adhere to the internal components of the fuel pump, reducing its performance. Reduced fuel pump performance can result in an engine stall, increasing the risk of crash.
The affected vehicles have fuel tanks that were manufactured with insufficient welds which may separate and allow fuel to leak out. A fuel leak in the presence of an ignition source may result in a fire.
