2017 Model S Air Suspension Clunking Noise & Uneven Ride

ClearTheCode admin answer:

1. Inspect for Leaks: The most common cause of uneven ride height and air suspension issues is a leak in an air spring (air strut) or an air line. Visually inspect around the air springs for any signs of moisture or damage.
2. Listen for Compressor Activity: If the air compressor is constantly running or running more frequently than usual, it could indicate it's working harder to compensate for a leak.
3. Check Suspension Components: The clunking noise could be related to worn suspension components such as control arm bushings, ball joints, or sway bar links, which can be exacerbated by an improperly functioning air suspension.
4. Software Calibration: Sometimes, a recalibration of the air suspension system can resolve minor height discrepancies. This is typically done by Tesla service.

• When to See a Shop: You should schedule a service appointment immediately. Continued driving with a compromised air suspension can lead to further damage to the compressor or other suspension components, and it significantly impacts safety and handling. Tesla service can perform a diagnostic scan (though specific OBD-II codes for air suspension leaks are rare, Tesla's internal system will log pressure discrepancies) and physically inspect the air springs, lines, and other suspension parts to identify the exact source of the leak or mechanical failure. This is a known issue for some earlier Model S vehicles, and Tesla has revised parts over time.
