2019 Acura MDX Complaints

I had to coast to the side of the road and it wasn't driveable. I was forced to have it towed to Acura to find out it's a rocker arm oil pressure switch that apparently goes out after 60,000-100,000 miles. Without warning, this is a huge safety issue.

  • Unknown Or Other, lane Departure, forward Collision Avoidance 12/10/2025

    Front windshield camera went bad due to overheating. When malfunction it gives multiple warning lights, everything that has to deal with front windshield camera does not work.

  • Electrical System, unknown Or Other, service Brakes 11/18/2025

    Turned on my car last night and many lights appeared including emissions system problem, electronic brake problem and SH-AWD malfunctioning. All the lights came on at once. According to forums, this is happening with many Acura RDX, MDX models and manufacturer does not have a clear way to repair or resolve the issue. My car has had all the routine maintenance and is scheduled for the 2 recalls to be repaired next week.
