2019-2025 Tesla Model S: Guide to Raven Adaptive Air Suspension Shock Failures

Understanding the 'Raven' Suspension

In mid-2019, Tesla introduced a significant update to the Model S, codenamed 'Raven'. A key part of this update was a new, fully-adaptive air suspension designed in-house. This system replaced the previous suspension and offers more precise, faster control over both ride height and damping (stiffness). All 2019 and newer Model S vehicles, including Long Range and Plaid trims, are equipped with this 'Raven' adaptive suspension. It's important to know that parts for the Raven system are generally not interchangeable with pre-2019 models.

Common Symptoms of a Failing Shock Absorber

Because the Model S is so quiet, suspension noises are often more noticeable than in a gasoline-powered car. Failure can manifest in several ways, from simple noises to critical vehicle warnings.

• Vehicle Sagging or Leaning: The most obvious sign of a problem is a visible drop in ride height at one corner, especially after being parked overnight. This almost always points to a leak in the air spring portion of the shock assembly.
• "Suspension System Fault" Warning: A yellow or red warning light on the instrument panel indicates the car's computer has detected a problem. This can be caused by a leak, a faulty sensor, or an electrical issue with the shock itself. A red warning may indicate the system is disabled and requires immediate attention.
• Excessive Air Compressor Noise: The air suspension compressor should be barely audible. If you hear it running loudly or for extended periods, it's likely overworking to compensate for a leak in one of the air struts. Ignoring this can lead to premature compressor failure.
• Clunking or Rattling Noises: A clunking or popping sound, especially at low speeds over bumps, can indicate a worn shock absorber. However, these noises can also be caused by other worn suspension components like control arm bushings or sway bar links, so proper diagnosis is important.
• Poor Ride Quality: A bouncy, harsh, or swaying ride can be a symptom of a failing shock absorber, as the damping function is compromised. This can also negatively affect braking performance.

Known Issues, TSBs, and Recalls

As of early 2026, there are no active NHTSA safety recalls specifically for the shock absorbers on the 2019-2025 'Raven' Model S. However, Tesla's suspension systems on earlier models have faced scrutiny. NHTSA investigated front suspension fore link failures on 2015-2017 models but closed the investigation without a recall, determining the vehicles remained controllable after a failure. Tesla has also issued recalls in China for suspension components on older vehicles. While these do not directly apply to the 2019+ Raven models, they highlight a history of suspension component wear.

Some owners have reported issues with the electrical connector on the shock becoming damaged, allowing water to enter and cause a short, which generates a fault code and requires strut replacement.

Buying a Used Suspension Shock Absorber

For a complex, electronically controlled part like this, a high-quality used OEM unit is often a smarter choice than a cheap, new aftermarket part. Aftermarket units may lack the sophisticated adaptive damping control, leading to error messages and a compromised ride. A used OEM part ensures perfect integration with the vehicle's systems.

What to Inspect:

• Check for Leaks: The most critical inspection. Look for any oily residue on the main body of the shock. This indicates the internal hydraulic damper has failed. Also, check the rubber air spring bladder for any cracks, perishing, or powdery residue that could signal a past or present air leak.
• Inspect the Electrical Connector: Carefully check the plastic connector and pins. Any signs of corrosion, bent pins, or cracks in the connector housing are major red flags. A damaged connector often means the entire strut is unusable.
• Verify the Part Number: Compatibility is crucial. Raven suspension parts are not interchangeable with older models. Always match the OEM part number from your failed part to the used replacement. Part numbers are often position-specific (e.g., front left vs. rear right).
• Examine for Physical Damage: Look for any dents, deep scrapes, or bends in the shock body or mounting points. This could indicate the part came from a vehicle involved in a collision, and its integrity may be compromised.
• Check the Air Line Fitting: Ensure the threaded brass fitting for the air line is clean and the threads are not stripped or damaged.

Cost Breakdown

Replacing a Tesla Model S air strut can be expensive, making a used OEM part an attractive option. Prices can vary based on location and the specific part.

Note: Labor costs can vary significantly. Total replacement cost at a dealership or independent shop can range from $1,500 to over $4,000 for a single corner.

Replacement Overview & Difficulty

Replacing a Model S air strut is an advanced DIY job. It requires knowledge of suspension work and careful handling of the high-pressure air system.

• Difficulty: 4 out of 5
• Key Steps: The vehicle MUST be put into 'Jack Mode' or 'Service Mode' via the touchscreen before lifting. This deactivates the auto-leveling feature and prevents damage. The air spring must be safely depressurized before removing any bolts. This is often done by slightly loosening the air line fitting at the strut. After installation, the system will need to be re-pressurized, and a wheel alignment is highly recommended.
