The Acura MDX bills itself as the premium option in the midsize crossover market, especially compared to its mainstream counterpart, the Honda Pilot, with which it shares the same platform. With its highly agile V6 powertrain, spacious first- and second-row seating, and genuine leather interior, the MDX certainly makes a convincing argument.
But how is it in terms of reliability?

What Are the Most Common Issues with Acura MDXs?
While the Acura MDX is certainly no pushover in terms of reliability, it doesn’t come without its share of problems. The following are several of the more notable Acura MDX problems and recalls and the affected model years.
Transmission Failure
The transmission found in many Acura MDX model years is supposedly prone to mechanical failure, resulting in symptoms ranging from an illuminated check engine light to rough shifting. Honda recommends strict adherence to maintenance schedules and part replacement intervals to ensure a smooth and worry-free operation of the transmission.
Affected Model Years

Faulty Transmission Torque Converter

Excessive Oil Consumption

Affected Model Years:

Auto Idle Stop Issues
Auto Idle Stop shuts the engine off while holding the brakes when waiting at a stop light, and then the engine should restart automatically when the driver releases the brake and presses the accelerator. But some owners report that their MDX shifts into neutral when the engine restarts and that they can't shift into drive without turning off the engine and then restarting it.
Affected Model Years:

VCM Issues
Numerous customer complaints have also been made regarding the Variable Cylinder Management feature in Acura MDX models manufactured since the mid-2010s. In fact, 2025 Acura MDX VCM problems are one of the most common reports found online. The VCM reportedly puts excessive stress on the engine or motor mounts, resulting in noticeable engine vibration and engine mount failure.
Repairs made by MDX owners range from “neutralizing” the engine mounts to reduce vibration to disabling the VCM entirely, although these are not guaranteed fixes.
