Air Suspension Malfunction on 2023 R1S - Vehicle Not Leveling

Vehicle: 2023 Rivian R1S Adventure

Hi everyone,

I'm having a frustrating issue with the air suspension on my 2023 Rivian R1S Adventure trim. Lately, I've noticed the vehicle isn't leveling correctly, especially after parking or when I change drive modes. Sometimes the front end sags, or one side seems lower than the other. I've also started hearing a louder-than-usual whirring noise from what I assume is the air compressor, and it seems to run more frequently.

I haven't hit any major potholes or had any incidents that would damage the suspension. I'm worried this could be a sensor issue, a leak, or a problem with the compressor itself. Has anyone else experienced similar air suspension problems with their R1S? Are there any common TSBs (Technical Service Bulletins) for this?

Any insights or advice on what to check before taking it to the service center would be greatly appreciated!

Air suspension systems, while offering superior ride comfort and adjustability, can develop issues over time. Your description of uneven leveling and a frequently running, noisy compressor points to a few common culprits. Rivian's air suspension system is complex, but here's a breakdown of potential causes and steps:

  1. Common Causes:

    • Air Leaks: The most frequent cause of uneven leveling and a constantly running compressor is a leak in the air spring bags, air lines, or fittings. Even small leaks can cause the system to work harder to maintain pressure.
    • Compressor Failure: If the compressor is running excessively and is louder, it could be failing, struggling to build pressure, or overheating. This can be due to age, wear, or being overworked because of a leak.
    • Height Sensor Malfunction: The system relies on height sensors at each wheel to determine the vehicle's level. A faulty sensor can send incorrect readings to the control module, leading to improper leveling.
    • Control Module Issues: Less common, but the air suspension control module itself could be malfunctioning, leading to incorrect commands.
    • OBD Codes: Relevant diagnostic trouble codes (DTCs) often associated with air suspension issues include:
      • C0561: System Voltage Low (can affect compressor operation)
      • C0575-C0580: Related to height sensor circuit malfunctions (e.g., C0575 Left Front Height Sensor Circuit Malfunction)
      • C0585-C0590: Related to air pressure sensor or solenoid valve issues.

  2. What to Check:

    • Visual Inspection: Look under the vehicle for any obvious damage to air lines or air springs. Sometimes, a torn boot or a kinked line is visible.
    • Listen for Leaks: With the vehicle parked, try to listen for hissing sounds around the wheels or under the vehicle, especially after the compressor has run.
    • Check for TSBs: Rivian has issued TSBs for various components. It's worth checking with a service advisor if there are any active TSBs related to air suspension for your 2023 R1S model year.

  3. When to See a Shop:

    • Immediate Action: If the vehicle is severely uneven, bottoming out, or if you receive a 'Suspension Fault' warning on your dash, it's crucial to schedule service immediately. Driving with a compromised air suspension can be unsafe and cause further damage.
    • Persistent Symptoms: Since you're experiencing persistent unevenness and an overworked compressor, it's highly recommended to have Rivian Service diagnose the issue. They have specialized tools to pinpoint leaks, test compressor function, and check sensor calibration. Ignoring these symptoms can lead to complete suspension failure or damage to other components.
