Uneven Ride Height & Suspension Warning on my 2022 Lucid Air Grand Touring

Vehicle: 2022 Lucid Air Grand Touring

Hey everyone,

I've been experiencing a really strange issue with my 2022 Lucid Air Grand Touring lately. Over the past week, I've noticed that the car seems to be sitting lower on the front passenger side, and it's become quite noticeable, especially when parked. The ride quality also feels a bit off, less smooth than usual.

To make things more concerning, a 'Suspension System Malfunction' warning light has popped up on the dashboard. It's not constant, but it appears intermittently, usually after driving for a bit. I've checked the tire pressures, and they're all good.

Has anyone else with a Lucid Air experienced anything like this? What could be causing this uneven ride height and the warning light? Any advice on what I should check before taking it into service?

ClearTheCode admin answer:

An uneven ride height combined with a suspension warning light on your 2022 Lucid Air Grand Touring indicates a problem with the vehicle's adaptive air suspension system. This is a critical system for ride comfort and handling, so prompt diagnosis is recommended.

Here are the common causes and steps:

  1. Air Spring Leak: The most frequent cause of uneven ride height in air suspension systems is a leak in one of the air springs (also known as air bags or air struts). Over time, rubber components can degrade, leading to small cracks or punctures that allow air to escape. This would cause the affected corner of the vehicle to sag.
  2. Air Suspension Compressor Failure: The compressor is responsible for supplying air to the air springs. If it's failing or not operating efficiently, it may struggle to maintain the correct pressure, especially if there's a minor leak elsewhere. A failing compressor might also trigger system warnings.
  3. Ride Height Sensor Malfunction: Each corner of your Lucid Air has a ride height sensor that tells the suspension control module the vehicle's current height. If a sensor is faulty, it might send incorrect data, causing the system to either over-inflate or under-inflate an air spring, leading to an uneven stance.
  4. Suspension Control Module (SCM) Issues: Less common, but a fault within the SCM itself could lead to incorrect commands being sent to the air springs or compressor, resulting in system malfunctions and warning lights.

When to See a Shop:

YouYou should schedule a service appointment with a Lucid service center as soon as possible. While the car might still be drivable, an impaired suspension system can affect:

  • Handling and Stability: Especially at higher speeds or during cornering.
  • Braking Performance: Uneven weight distribution can impact braking efficiency.
  • Tire Wear: Irregular ride height can lead to premature and uneven tire wear.

What a Shop Will Do:

  • Diagnostic Scan: They will connect to the vehicle's OBD-II port to retrieve specific diagnostic trouble codes (DTCs) related to the suspension system. Common codes might include manufacturer-specific codes for air spring pressure, height sensor out of range, or compressor performance issues.
  • Visual Inspection: Technicians will inspect the air springs for visible damage or leaks, check air lines, and examine electrical connections to the height sensors and compressor.
  • System Testing: They will perform functional tests of the air suspension components using specialized diagnostic tools to pinpoint the exact failure point.

Do not delay addressing this issue, as continued driving with a compromised suspension can lead to further damage or safety concerns.
