2022 Acura MDX electrical problems

Filed Aug 12, 2026 · Electrical, Steering · IL

While driving at approximately 35 mph on a surface street with my wife and five-year-old son in the vehicle, the electric power steering system failed and steering assist was reduced. The instrument panel simultaneously displayed and cycled through multiple warnings including "Electric Power Steering System Problem — Steering Assist Reduced," "Brake System — Brake Hold System Problem," Vehicle Stability Assist, and Hill Start Assist. There were no warning lamps, messages, or symptoms of any kind prior to this failure; the first indication was the failure itself while the vehicle was in motion. On the two engine starts following the incident, the same dashboard warnings reappeared, although power steering and vehicle operation seemed normal. On the two starts after that, the vehicle started with no warnings and no indication of any problem. So the steering effort increased during the initial failure and I was unable to rely on power assist while moving in traffic, which created a risk of loss of directional control and a crash for my occupants and other road users. On Aug 11,2026, the vehicle was taken to an authorized Acura dealer, which confirmed a stored diagnostic trouble code and diagnosed a failure of the VSA (Vehicle Stability Assist) modulator-control unit, recommending replacement. The vehicle has not been inspected by the manufacturer, police, or an insurance representative. No repairs have been performed to date and the vehicle and component remain available for inspection upon request. Mileage at the time of failure was 40,090. I have video of the instrument panel recorded during the event and it is available upon request. I have reviewed complaints filed with the federal safety agency describing what appears to be the same simultaneous multi-system failure on 2022 and 2023 Acura MDX vehicles.

I am filing a complaint regarding my 2022 Acura MDX Type S with approximately 70,700 miles. The vehicle developed a suspension system warning, and upon inspection by an Acura dealership, I was informed that the suspension stroke sensor and floor wiring harness are corroded and require replacement. I was quoted approximately $12,000 for the repair. This failure is extremely concerning because the vehicle is only a few years old and this type of corrosion affecting a major wiring harness should not occur under normal operating conditions. The affected components are part of the suspension system, which directly impacts vehicle handling and safety. Due to the failure, the suspension system may not function properly, potentially affecting ride height, stability, and overall control of the vehicle. This raises safety concerns, especially at highway speeds or during emergency maneuvers. There was no prior warning of water intrusion or external damage that would reasonably explain this level of corrosion. This appears to be a premature failure of a critical electrical component. Acura has only offered minimal goodwill assistance, leaving the majority of this extremely costly repair as the responsibility of the owner. I am concerned that this may be a broader issue affecting other vehicles and that it could pose a safety risk if not addressed. I am requesting that this issue be investigated. Thank you.

The rear passenger door actuators have both failed. The rear hatch will not unlock using the touch button. We just received notice that our transmission/transfer case needs replacing. $13K for this.

The battery drains quickly. Have replaced the battery twice since 2022. something in the car is draining the battery and making it fail. infotainment screen sometimes stays grey and doesn't go black when car is off. many 2022 mdx owners are having similar battery drain issues requiring frequent battery replacements. please push Acura for a recall and fix.

As I was turning right (slowly accelerating from a complete stop) into a shopping center parking lot, I was entering into the lane behind a vehicle that had just passed in front of me (and was headed in the same direction I was going to turn). My 2022 Acura MDX Low Speed Braking Control system engaged for no reason. The breaks slammed hard bringing the car to a hard, sudden stop, and I thought I had been rear-ended by the car behind me. I pressed the gas slowly again and was able to pull into a parking spot and checked my back bumper…PERFECTLY FINE! I googled the issues I experienced and found this is a common problem! This is a dangerous problem! Please hold Acura accountable to fix this issue! For now, I have to remember to turn this Low Speed Braking Control System OFF EVERY TIME I power on my MDX! I am now scared to drive my car!

I was driving my car on the interstate and momentarily stopped due to traffic congestion. My engine idle stop feature was on and engaged as expected for the short stop, but the vehicle then stalled when I attempted to drive. There seemed to be an electrical issue with various lights coming on the dash to indicate a problem. I could not get the car to restart and was stuck in the left lane with cars then going around my stalled vehicle. I called 911 for help after I could not restart the car after 3 attempts. After approximately 5 minutes, I pressed the ignition button again, and this time my car was able to restart and drive normally so that I could exit the highway.
