# Service bulletin SB\-20\-31\-001

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.

- [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.
