2025-2026 Lucid Gravity Suspension Subframe Mount: Inspection Guide for a New EV
As a new vehicle, the Gravity has no documented subframe mount failures, so this guide focuses on general symptoms and inspecting used parts from salvage vehicles.
- There are NO known recalls or common failures for the 2025-2026 Gravity's subframe mounts; the vehicle is too new.
- If buying a used mount, it will be from a salvage vehicle. Prioritize inspecting for collision damage (cracks, bending) over signs of wear.
- General failure symptoms to watch for as the vehicle ages include clunking noises over bumps, loose steering, and excessive vibrations.
- This is not a DIY repair. Replacement requires supporting the subframe and should be done by a professional with EV experience.
Known Issues, TSBs, and Recalls for 2025-2026 Lucid Gravity
As of June 2026, there are no specific recalls, Technical Service Bulletins (TSBs), or widespread owner complaints related to the suspension subframe mounts on the 2025-2026 Lucid Gravity. This is expected for a vehicle that has only been on the market for a short time.
However, several recalls have been issued for other areas of the vehicle. It is important to be aware of these to understand the context of an early-production vehicle, but they are not related to the suspension subframe.
- NHTSA Recall 26V192000: Insufficient welds on the second-row seat lap belt anchor brackets could cause them to fail in a crash.
- NHTSA Recall 26V018000: A software issue could prevent the rearview camera image from displaying when the vehicle is in reverse.
- NHTSA Recall 25V855000: Incorrect front seat backrest covers could obstruct the side airbag from deploying properly.
Pro Tip: Always check the latest recall information for your specific vehicle by entering its VIN on the NHTSA website (nhtsa.gov/recalls) before purchasing or performing repairs.
Symptoms of a Failing Subframe Mount
While no common failures are documented for the Gravity yet, subframe mounts are wear items on all vehicles. As these vehicles accumulate mileage, watch for the following general symptoms that indicate a mount may be failing.
Clunking or Knocking Noises
The most common symptom is a clunking, popping, or knocking sound from the front or rear of the vehicle. This noise is most noticeable at low speeds, especially when driving over bumps, potholes, or making sharp turns. The sound is caused by the subframe shifting and making contact with the vehicle's body due to a worn or collapsed bushing.
Excessive Vibration
A new, noticeable vibration felt in the steering wheel or through the floor of the cabin can be a sign of a bad mount. The rubber bushing is designed to dampen vibrations, and when it fails, those vibrations from the road and drivetrain are transferred directly into the vehicle's structure.
Poor Steering and Handling
If the steering feels vague, loose, or less responsive than usual, it could be related to a failing subframe mount. Worn mounts can allow the subframe to shift, which changes the suspension geometry and affects steering alignment. This can make the vehicle feel unstable, especially during cornering or braking.
Uneven Tire Wear
A bad subframe mount can lead to persistent alignment issues that cannot be corrected. If the subframe is not held securely in place, the wheel alignment will constantly change, causing accelerated and uneven tire wear, often on the inner or outer edges of the tires.
Buying a Used 2025-2026 Gravity Subframe Mount
Given the newness of the Lucid Gravity, any used subframe mount available will have come from a very low-mileage vehicle that was in a collision. This changes the inspection process compared to buying a part for an older car.
Warning: The initial parts catalog description for this part may be vague, such as "MISC. BRACKET." Do not rely on this title. Always verify the part by comparing it to photos of your original part and matching the OEM part number, P21B1672004.
What to Check Before You Buy:
- Inspect for Collision Damage: This is your primary concern. Look for any signs of cracks, bending, or deformation in the metal structure of the mount. A part damaged in a crash is unsafe to use. Check all weld points for stress fractures.
- Examine the Rubber Bushing: Even on a low-mileage part, check the rubber for tears, deep cracks, or signs that it has separated from the metal housing (delamination). While wear is unlikely, the force of a collision can tear the bushing.
- Verify Mounting Points: Ensure all bolt holes are round and undamaged. Any elongation or damage to a mounting hole suggests the part was subjected to extreme force and should be rejected.
- Check for Corrosion: Surface rust on the metal is usually cosmetic, but heavy corrosion or flaking, especially around the rubber-to-metal bond, is a red flag. This is particularly important for vehicles from areas that use road salt.
- Confirm Part Number: If possible, get a clear photo of the part number stamped or printed on the mount to ensure it is an exact match for your needs.
Typical Installation Difficulty
Difficulty Rating: 5 out of 5 (Professional Recommended)
Replacing a subframe mount is not a typical DIY job, especially on a new, high-voltage electric vehicle like the Lucid Gravity. The subframe must be safely supported with specialized equipment before the mounts can be unbolted. On some vehicles, this requires lowering or removing the subframe entirely, which is a complex and labor-intensive process. Given the lack of public service manuals and the vehicle's complex systems, this repair should be left to a qualified professional with experience in modern EVs.
Cost Comparison for Subframe Mount Replacement
These costs are estimates as of June 2026. Prices for a new vehicle platform can be volatile and difficult to predict.
| Part/Service | Estimated Cost | Notes |
|---|---|---|
| New OEM (from Lucid) | $250 - $500+ | Must be purchased from a Lucid service center. Price is for the part only. |
| New Aftermarket | Not Available | The vehicle is too new for the aftermarket to have developed replacement parts. |
| Used OEM (Recycled) | $150 - $350 | Price is highly dependent on availability from salvage yards. Inspect carefully for collision damage. |
| Shop Labor | $400 - $900 | Labor can take 3-6 hours. EV-certified shops may charge a premium. |
| Total Professional Replacement | $650 - $1,400+ | Using a new OEM part and professional labor. |
Frequently Asked Questions (FAQ)
Are there any known problems with the 2025-2026 Gravity subframe mount?
No. As of mid-2026, there are no recalls, TSBs, or common failure patterns reported for this part. The vehicle is too new for long-term wear issues to have appeared.
Can I replace a subframe mount myself?
It is not recommended. The job requires safely supporting the vehicle's subframe, which holds the motors and suspension. This is a complex task that requires specialized equipment and expertise, particularly on a high-voltage EV. Improper installation can lead to serious safety issues.
Why can't I find an aftermarket version of this part?
The Lucid Gravity is a new, low-volume luxury vehicle. Aftermarket manufacturers typically wait until there is a significant number of vehicles on the road and a proven demand for a part before investing in the engineering and tooling to produce it. This process can take several years.
Is the part the same for the front, rear, left, and right sides?
This is unconfirmed. Subframe mounts are often position-specific. The provided part number, P21B1672004, is likely for one specific location. It is critical to match the part number from your original mount or consult a Lucid service center to ensure you are purchasing the correct part for the specific corner of the vehicle you are repairing.
