2022-2025 Lucid Air Suspension Control Module: Faults, Recalls, and Replacement Guide

Symptoms of a Failing Active Suspension Control Module

A problem with the Lucid Air's suspension can originate from a mechanical part, a sensor, or the control module itself. Distinguishing the cause is key to a correct diagnosis. The most common indicator of a system issue is a warning message on the driver display.

"Suspension Control Fault. Contact Service Center" Warning

This is the most definitive warning message related to the adaptive suspension system. While it can point to a faulty module, it is more frequently associated with mechanical issues. Notably, this exact message was cited in a 2022 recall for a small number of vehicles with defective front strut dampers. If this message appears, the vehicle's computer has detected a problem that requires professional diagnosis. It could be a failed sensor, a wiring issue, a mechanical problem with a strut, or, less commonly, a failure of the control module itself.

Uneven Ride Height or Sagging

If you notice one corner of the car is lower than the others, especially after being parked overnight, it often points to a leak in an air spring or a problem with a ride height sensor. While the control module commands the system, a physical inability to hold air pressure is typically a mechanical failure, not an electronic one.

Loud Rattling or Squeaking Noises

Owners have reported metallic rattling or squeaking sounds from the suspension over bumps. In some cases, this has been traced to loose stabilizer bar end link nuts, which was the subject of a service campaign (TSC-S0925-020). These noises are almost always mechanical and are not symptoms of a failing electronic control module.

Associated OBD-II Diagnostic Trouble Codes (DTCs)

At present, there is no publicly available, vehicle-specific list of OBD-II codes for the Lucid Air's suspension control module. Generic codes for air suspension systems often begin with a 'C' (for Chassis), such as C1725 (Air Suspension Front Pneumatic Failure) or C1726 (Air Suspension Rear Pneumatic Failure). However, diagnosing a Lucid requires specialized equipment that can communicate with its proprietary systems. A standard OBD-II scanner may not be able to read these specific chassis codes.

Known Issues, TSBs, and Recalls

The most significant suspension-related issue for the 2022-2025 Lucid Air has been a mechanical recall, not a widespread failure of the control module.

NHTSA Recall 22V090: Front Strut Damper Failure

In February 2022, Lucid recalled 203 units of the 2022 Air due to front strut dampers that were improperly manufactured by a supplier. The defect could cause a snap ring to fail, leading to a sudden loss of ground clearance, vehicle vibration, and potential damage to the front brake line, increasing the risk of a crash. The recall involved inspection and, if necessary, replacement of the front strut dampers at no cost to the owner. This issue is specific to a limited batch of early vehicles.

Service Campaign TSC-S0925-020: Front Stabilizer Bar End Links

Some owners have experienced loud rattling from the front suspension, which was diagnosed as stabilizer bar end link nuts that needed to be re-torqued to the correct specification. This is a minor mechanical adjustment covered by a service campaign.

Programming and Calibration Requirements

YES, a replacement Active Suspension Control Module must be programmed and calibrated to the vehicle. This is not a plug-and-play part.

Vendors of used modules explicitly state that programming may be required. The process, generally known as a 'relearn' or 'calibration,' involves using a specialized diagnostic tool to communicate with the new module. During this procedure, a technician typically measures the ride height at all four corners of the vehicle on a level surface and inputs these values into the system. This establishes a new baseline for the module, ensuring the car sits level and the adaptive damping functions correctly.

Due to the complexity of Lucid's electronic architecture and its tightly controlled service network, this procedure must be performed at a Lucid Service Center or a Lucid-Certified Body Repair shop. Independent shops, even those with high-end tools, are unlikely to have the proprietary software required to program modules for a Lucid Air. DIY replacement is not considered feasible.

Buying a Used Active Suspension Control Module

Given the high cost of new electronic components, a used OEM module can be a cost-effective option. However, due to Lucid's strict repair policies and the need for programming, there are critical factors to consider.

• Match Part Numbers Exactly: Several part numbers exist, such as P11-SESD10-07 and P11-SESD10-06. It is absolutely essential to match the part number from your original module. Using an incompatible module will not work.
• Verify Professional Installation: Before purchasing, confirm that you have a Lucid Service Center or Lucid-Certified shop that is willing to install and program a customer-supplied used part. Some service centers may refuse to install parts they did not procure themselves.
• Inspect for Damage: When the part arrives, check the housing for any cracks or signs of physical damage. Most importantly, inspect the connector pins to ensure none are bent, corroded, or broken.
• Understand the Risks: Lucid's official position for post-accident repairs is to prohibit the use of any used or reconditioned suspension components. While this is primarily aimed at safety-critical mechanical parts, it reflects the manufacturer's emphasis on using new, warrantied parts installed through their certified network. A used module will not carry a warranty from Lucid.

Cost to Replace the Active Suspension Control Module

Pricing for Lucid Air components is not widely published and is subject to change. Repairs are almost exclusively handled by the official service network.

Note: Costs are estimates and do not include taxes or potential diagnostic fees. Labor for programming at a Lucid Service Center may be higher.
