Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 3 investigation files overlapping the 2026 MDX, and 2 remain open.

2026 Acura MDX with Acura Factory A Spec issued plastic floor mats. Accelerator pedal gets stuck behind the floor mat resulting in uncontrolled wide open throttle. Had to physically put my foot behind the pedal and pull pedal away from floor. Afterwards tried a few times to repeat the issue, 3/5 times was able to reproduce stuck pedal. Top of the drivers plastic floor mats, right side, has a U cut out for the accelerator pedal. This needs to be trimmed another 1/2â or more to stop the issue. Could result in severe or fatal consequences.

I have experienced the vehicle not unlocking when the key fob is near(in my pocket) the vehicle and my hand is touching the door handles. The vehicle is designed to unlock when the key fob is in close proximity while hands are on the handle. This is a safety/security concern because in an emergency, the vehicle does not function as it is intended to.
