# Tesla TAS_a313 / TAS_a314: Adaptive Ride Control Fault

By the EV Fix Guide editorial team · Updated October 24, 2026 · [How we estimate costs](https://evfixguide.com/about#how-we-estimate-costs)

## Quick answer

TAS_a313 and TAS_a314 appear on cars with adaptive suspension damping when the system can no longer adjust the dampers. With TAS_a313 the ride may be softer or firmer than usual; with TAS_a314 Tesla also limits speed. The car is OK to drive, but persistent alerts need a suspension diagnosis. At a Tesla Service Center this typically costs **$800 - $2,000 (Per adaptive damper, installed)**. An independent shop charges about **$500 - $1,400 (Per damper, installed)** — potential savings of **30% - 40%**. **Do not attempt this at home.**

## Symptoms

- 'Adaptive ride control degraded - Ride comfort may be reduced' alert with a yellow indicator (TAS_a313)
- 'Adaptive ride control unavailable - Vehicle speed limited' alert with a red indicator (TAS_a314)
- Ride feels noticeably harsher, floatier or bouncier than normal
- Often after hitting a pothole, or in wet or freezing weather

## Repair cost: Tesla vs independent shop vs DIY

| Option | Typical cost (USD) |
| --- | --- |
| Tesla Service Center | $800 - $2,000 (Per adaptive damper, installed) |
| Independent shop | $500 - $1,400 (Per damper, installed) |
| DIY | Not recommended |
| Potential savings | 30% - 40% |

## Can an independent shop fix it?

Independent shops that work on Model S/X air suspension can usually diagnose and replace a failed adaptive damper or damper wiring for less than Tesla. Make sure the shop has experience with Tesla's adaptive dampers and can clear the alert afterwards.

## How professionals repair it

**Safety warning:** Owners can check for obvious damage and see whether the alert clears after a restart. Replacing adaptive dampers or wiring is a lift job with suspension and electrical work, so leave it to a shop.

### Tools a shop uses

- Flashlight (to look for damage or leaks at each wheel)
- Tesla app (to log the alert)

### Steps

1. Keep driving carefully; Tesla says the car is OK to drive. With TAS_a314, expect a speed limit and take corners gently.
2. Park, let the car sleep, and start a new drive. If the alert clears and does not return, it was likely temporary.
3. Look at each wheel for oil on the damper body, a damaged connector or wiring, especially after a pothole impact.
4. If the alert persists over several drives, note which corner feels different and book a suspension diagnosis.
5. Ask for a quote on the single faulty damper. You rarely need to replace all four.

**Pro tip:** A red TAS_a314 alert after a hard pothole hit is worth checking the same week: a damaged damper can also hide a bent control arm or wheel.
