2022-2024 Lucid Air Subframe Mount: Investigating Suspension Clunks and Noises
An in-depth reference for identifying worn subframe mounts, understanding related suspension issues, and making smart purchasing decisions for your Lucid Air.
- Clunking noises on a Lucid Air may be caused by simple loose sway bar links, which should be checked before suspecting more complex subframe mount failure.
- A bad subframe mount will cause clunking, steering instability, and vibrations; visual inspection for cracked or separated rubber is the best diagnosis.
- Replacement is a very difficult (5/5) and expensive job requiring professional tools and a subsequent wheel alignment; it is not a DIY-friendly task.
- There are no recalls for subframe mounts, but a 2022 recall for front struts and another for a rear subframe wiring harness highlight the importance of inspecting this area of the vehicle.
Known Issues & Recalls for the 2022-2024 Lucid Air
While the Lucid Air is a relatively new vehicle, some common patterns have emerged from owner reports and official communications. It's important to distinguish between issues directly related to the subframe mounts and other suspension noises that can produce similar symptoms.
Owner-Reported Noises
A number of Lucid Air owners have reported metallic rattling, clunking, or popping sounds from the front suspension, particularly at low speeds over bumps. In many of these cases, service centers found that the stabilizer (sway bar) end link nuts were not torqued to the correct specification from the factory. While this is a separate part from the subframe mount, the noise it creates can be very similar to a failed mount, causing a loud, alarming rattle that sounds like a major component is loose.
Official Recalls and Campaigns
As of mid-2024, there are no specific recalls or technical service bulletins (TSBs) for failing subframe mounts on the 2022-2024 Lucid Air. However, several other suspension and subframe-related recalls are important to be aware of:
- Front Strut Damper Recall (February 2022): A recall was issued for 203 vehicles from the 2022 model year due to an incorrectly installed snap ring on the front strut dampers, supplied by Bilstein. This defect could cause a sudden loss of ride height or damage to the front brake line.
- Rear Subframe Wiring Harness Recall (2024-2025 models): Some Pure RWD models were recalled because a short rear subframe wiring harness could become strained and cause a loss of power to the rear drive unit.
These recalls show that the subframe and suspension areas have been subject to factory and supplier-related issues, making a thorough inspection of any related component critical.
Symptoms of a Failing Subframe Mount
While some noises on a Lucid Air may be due to loose sway bar links, true subframe mount failure has a distinct set of symptoms. Worn mounts allow for excessive movement between the subframe and the vehicle's body, leading to the following issues:
- Clunking or Popping Sounds: A heavy 'clunk' or 'pop' may be heard or felt when accelerating, braking, or going over bumps. This is the sound of the subframe shifting and making contact with the chassis.
- Excessive Vibration: A noticeable increase in vibration felt through the steering wheel or the floor of the cabin, especially at idle or on rough roads. The mounts are no longer effectively absorbing drivetrain and road vibrations.
- Poor or Wandering Steering: A feeling that the steering is loose, vague, or sloppy. Because the subframe houses steering and suspension components, its unwanted movement can throw off the vehicle's alignment, causing it to pull to one side or feel unstable.
- Uneven Tire Wear: If a bad subframe mount causes a persistent alignment issue, it can lead to accelerated and uneven wear on the edges of the tires.
Pro Tip: A simple way to check for excessive movement is to have a helper turn the steering wheel from side to side with the engine on while you observe the subframe area (with all safety precautions). If you see significant shifting of the entire subframe relative to the body, the mounts are likely worn. Another test involves carefully jacking up a corner of the subframe; if the subframe rises noticeably before the vehicle body begins to lift, the bushing has failed.
Buying a Used 2022-2024 Lucid Air Subframe Mount
Given the high cost of new OEM parts for a luxury EV, a quality used subframe mount can be a smart purchase. However, a thorough inspection is essential to ensure you are getting a reliable part.
What to Inspect
- Check the Rubber: The most important check is the condition of the rubber. Look for any cracks, tearing, or signs of dry rot. The rubber should be pliable, not hard and brittle.
- Look for Separation: Check the bond between the rubber insulator and the metal housing (inner and outer). Any sign of separation means the mount has failed and should be rejected.
- Inspect for Leaks: Some subframe mounts are hydraulic (fluid-filled) for better damping. Look for any dark, oily residue or wetness on the mount, which indicates the internal bladder has ruptured and the fluid has leaked out.
- Examine the Metal Housing: Inspect the aluminum or steel casing for any cracks, deep corrosion, or signs of damage from the removal process. Ensure all mounting holes are clean and not elongated.
Compatibility
The known OEM part number for a Lucid Air subframe mount is P11NSH100. Always verify the part number on the used component matches what is required for your vehicle's specific location (e.g., front, rear, left, right) and trim level. Using an incorrect mount can compromise the vehicle's ride quality and handling characteristics.
Replacement Difficulty & Cost
Replacing a subframe mount is a complex and labor-intensive job that is not recommended for beginners.
- Installation Difficulty: 5 out of 5 (Professional Recommended)
- Why it's difficult: The process requires a vehicle lift and a special subframe support stand. The subframe must be lowered, which often involves disconnecting steering linkages, suspension components, and sometimes drive unit connections. The old mounts must be pressed out of the subframe and the new ones pressed in using specialized hydraulic tools. Reassembly requires careful alignment and torquing all bolts to factory specifications.
- Consequences of Improper Installation: Failure to properly align and torque the subframe can lead to poor handling, persistent noises, and unsafe driving conditions. An alignment is always required after this procedure.

Frequently Asked Questions (FAQ)
What's the difference between a subframe mount and an engine/motor mount?
An engine or motor mount specifically holds the drive unit (motor) to the subframe. A subframe mount holds the entire subframe assembly (which includes the motor, suspension, and steering) to the car's body. They work together to control vibrations.
Do I need to replace all subframe mounts at once?
It is highly recommended. The mounts wear at a similar rate, and the labor to lower the subframe is the most expensive part of the job. Replacing all of them at the same time saves you from having to repeat the costly labor when another mount fails soon after.
Will a bad subframe mount cause a check engine light or warning message?
No, a failing subframe mount is a mechanical part and will not trigger a check engine light or a specific fault code on its own. However, if its movement causes damage to a connected sensor or wire, it could indirectly cause a warning.
Is an alignment necessary after replacing subframe mounts?
Yes, absolutely. The subframe is the primary anchor for all suspension and steering components. Lowering and reinstalling it will always alter the vehicle's wheel alignment. A full four-wheel alignment is required to ensure safety, proper handling, and to prevent premature tire wear.
