Vehicle: 2022 Tesla Model S Plaid

Hey everyone,

My 2022 Tesla Model S Plaid has recently started showing an "Air Suspension Malfunction" alert on the touchscreen. The ride quality has definitely deteriorated; it feels much bumpier than usual, and I've noticed the car isn't leveling itself properly when parked or when I get in.

Sometimes, one corner seems lower than the others. I've tried adjusting the ride height settings, but it either doesn't respond or reverts to the error message. No strange noises like hissing, but the ride is just off.

Is this a common issue with the newer Model S Plaid? What components should I be looking at, or is this a definite service center visit?

ClearTheCode admin answer:

An "Air Suspension Malfunction" alert on your 2022 Tesla Model S Plaid, especially with noticeable changes in ride height and quality, indicates a problem with the adaptive air suspension system. This system is crucial for comfort, handling, and efficiency.

  1. Observe Symptoms Closely:

    • Uneven Ride Height: Note which corner(s) are lower or higher than expected.
    • Compressor Noise: Listen for the air suspension compressor running excessively or not at all.
    • Hissing Sounds: While you haven't heard them, persistent hissing can indicate an air leak.

  2. Potential Causes:

    • Air Spring (Air Bag) Leak: The rubber air springs can develop small leaks over time, causing a corner to sag. This is a common wear item.
    • Air Suspension Compressor Failure: The compressor is responsible for pumping air into the system to adjust ride height. If it fails, the system cannot maintain pressure or adjust height.
    • Ride Height Sensor Malfunction: Each wheel has a sensor that tells the control module the current ride height. A faulty sensor can provide incorrect readings, leading to uneven leveling or system errors.
    • Air Line Leak or Valve Block Issue: The air lines connecting the compressor to the air springs, or the valve block that distributes air, can develop leaks or internal faults.
    • Suspension Control Module (SCM) Fault: The electronic control unit that manages the entire air suspension system could be faulty, leading to incorrect operation.
    • Software Glitch: Less common for persistent physical symptoms, but a software issue could interfere with sensor readings or system commands.

  3. When to See a Shop: Driving with a compromised air suspension can affect handling, tire wear, and potentially lead to further damage to suspension components. You should:

    • Schedule Tesla Service: Contact Tesla service immediately via your app. Provide a detailed description of the alert and the physical symptoms you're observing. They can run diagnostics to pinpoint the exact fault code.
    • Avoid Prolonged Driving: While short, careful drives might be possible, avoid long trips or driving at high speeds until the issue is resolved. The car's stability and comfort are compromised.
    • Do Not Attempt DIY Repairs: The air suspension system operates under high pressure and requires specialized tools and knowledge for diagnosis and repair. Incorrect handling can be dangerous or cause more damage.
