Noisy Suspension and Rough Ride in 2025 ZDX Type S

Vehicle: 2025 Acura ZDX Type S

My 2025 Acura ZDX Type S, with its adaptive air suspension, has developed a really annoying clunking sound coming from the front whenever I go over bumps or uneven pavement. The ride also feels much harsher than it used to, almost like the adaptive damping isn't working properly.

It's only got about 10,000 miles on it, so I wouldn't expect suspension issues this early, especially with a premium vehicle like the ZDX Type S. The noise is becoming more frequent and the ride quality is really deteriorating. What could be causing this, and is it a common problem for these vehicles?

Any advice on what to check or what to tell the dealership would be greatly appreciated.

ClearTheCode admin answer:

A clunking sound and a rougher ride in a relatively new 2025 Acura ZDX Type S with adaptive air suspension are definitely not normal and indicate a potential issue. Given the low mileage, this should be addressed promptly. Here’s a breakdown of common causes and next steps:

  1. Common Suspension Issues (Even on New Cars):

    • Sway Bar Links/Bushings: These are common culprits for clunking noises over bumps. They can wear prematurely or loosen, especially with the added weight of an EV.
    • Ball Joints/Tie Rod Ends: Worn or loose ball joints or tie rod ends can also cause clunking and affect steering feel.
    • Loose Components: Sometimes, a suspension component might not have been torqued correctly during assembly or a routine service.

  2. Adaptive Air Suspension Specifics:

    • Air Spring Leaks: A leak in an air spring (air bag) can cause the suspension to bottom out, leading to a harsh ride and potentially clunking. The system might also struggle to maintain proper ride height.
    • Compressor/Valve Block Issues: The air suspension compressor or valve block could be malfunctioning, preventing proper air pressure distribution and affecting damping.
    • Sensor Malfunction: The adaptive suspension relies on various sensors (e.g., ride height sensors, accelerometers). A faulty sensor can send incorrect data, leading to improper damping adjustments and a harsh ride. This might trigger specific diagnostic codes like C0031 (Wheel Speed Sensor) or C1200 (Suspension Control Module), though these are more for system failures than just noise.
    • Damper Issues: The adaptive dampers themselves could be faulty, failing to adjust damping rates as needed.

  3. When to See a Shop:

    • Given that your ZDX Type S is a 2025 model with only 10,000 miles, this issue should be covered under warranty. It is critical to take it to an authorized Acura dealership as soon as possible. Explain the specific symptoms: the clunking noise (when and where you hear it) and the perceived harshness of the ride.
    • The technicians will perform a thorough inspection of all suspension components, check for leaks in the air suspension system, and scan for any diagnostic trouble codes related to the adaptive suspension control module. Do not delay, as continued driving with a compromised suspension can lead to further damage or safety concerns.
