# Service bulletin SB\-20\-31\-005

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Certain Model 3 vehicles were manufactured with RH front damper assemblies that do not meet internal specifications, which may result in elevated NVH \(Noise, Vibration, and Harshness\) from the front of the vehicle.

## Other bulletins for the same vehicles and component

- [SB\-25\-31\-004](/bulletins/11020192.md), 2025-07-04, Service bulletin: SUSPENSION. A firmware diagnosis feature is being introduced on Model 3 and Model Y vehicles that monitors wheel alignment over time. This feature detects changes in wheel alignment that may be related to incorrect tire pressures, degraded ball joints, bushings or damaged suspension links. If the feature determines that an inspection at a Tesla Service Center is required, a customer\-facing alert will appear on the touchscreen.
- [SB\-20\-31\-006 R3](/bulletins/10203342.md), 2021-11-08, Service bulletin: STEERING; SUSPENSION. On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints. This may result in a creaking sound coming from the front suspension when steering at low speeds and under high loads. This is exclusively an NVH condition only and does not result in premature failure of the ball joints.
- [SB\-20\-31\-006 R2](/bulletins/10203341.md), 2021-11-08, Service bulletin: SUSPENSION. On certain Model 3, Model Y, and Model X vehicles, there may be a water ingress path to both front upper control arm ball joints that, over time, could possibly lead to surface corrosion of these ball joints.

This is exclusively an NVH condition only and does not result in premature failure of the ball joints.
- [SB\-20\-31\-004](/bulletins/10179542.md), 2020-09-08, Service bulletin: SUSPENSION. Certain Model 3 vehicles were manufactured with LH front damper assemblies that do not meet internal specifications, which may result in elevated NVH \(Noise, Vibration, and Harshness\) from the front of the vehicle.
- [SB\-20\-31\-002](/bulletins/10173428.md), 2020-04-06, Service bulletin: EQUIPMENT ADAPTIVE/MOBILITY; SUSPENSION:REAR; EQUIPMENT. On some Model 3 vehicles, the LH and/or RH rear damper top mount bolts were not fastened according to internal specifications and may create noise, vibration, and harshness.
