2020 NSX Type S - 'Adaptive Damper System Malfunction' Error

Vehicle: 2020 Acura NSX Type S

Hi everyone,

I'm experiencing an issue with my 2020 Acura NSX Type S. Recently, I've started getting an error message on the dash that says 'Adaptive Damper System Malfunction.' Along with this, the ride quality feels off – it's either too stiff and jarring, or sometimes feels overly soft and floaty, not consistent like it should be.

It seems to happen intermittently, sometimes after hitting a bump, other times just starting the car. I've tried cycling through the different drive modes (Quiet, Sport, Sport+, Track), but the error persists, and the ride doesn't seem to adjust properly. My car has about 18,000 miles.

Has anyone encountered this specific error with their NSX, especially a Type S? What was the resolution? I'm hoping it's something simple like a sensor, but I'm bracing for something more complex.

ClearTheCode admin answer:

An 'Adaptive Damper System Malfunction' in your 2020 Acura NSX Type S indicates a problem with the sophisticated electronic suspension system. This system uses sensors and electronically controlled dampers to adjust ride characteristics in real-time. Here's what could be going on:

  1. Damper Sensor Failure: Each damper has sensors that monitor wheel speed, body movement, and road conditions. If one of these sensors fails or provides incorrect readings, the system can trigger an error. This is a common point of failure.
  2. Wiring or Connector Issues: The wiring harness connecting the dampers and sensors to the suspension control module can become damaged, corroded, or have loose connections. This can lead to intermittent errors.
  3. Damper Unit Malfunction: The adaptive dampers themselves are complex units. Internal electronic or mechanical failures within a damper can prevent it from adjusting correctly, leading to the error message and inconsistent ride quality.
  4. Suspension Control Module (SCM) Fault: The SCM processes data from various sensors and sends commands to the dampers. A rare but possible cause is a fault within the control module itself.
  5. Physical Damage: Inspect the area around each wheel and damper for any visible signs of impact damage, bent components, or detached wiring that might have occurred from road debris or potholes.

When to See a Shop:

It's crucial to have your 2020 Acura NSX Type S professionally diagnosed. An Acura dealership or a specialist with appropriate diagnostic equipment can scan the vehicle for specific suspension-related trouble codes (e.g., C15xx codes for damper issues), pinpointing the exact component that has failed. Driving with a malfunctioning adaptive damper system can compromise handling and safety, especially in a high-performance vehicle like the NSX.
