# Service bulletin SB2139001R1

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.

- Type: Service bulletin

- Published by NHTSA: 2021\-11\-08

- Manufacturer's date: 2021\-09\-21
- NHTSA component: STEERING

## NHTSA's summary

Some versions of Model S and X front drive unit halfshafts might cause excessive vibrations during hard acceleration at higher ride height settings. This is exclusively an NVH issue and does not otherwise affect steering functionality, braking, or acceleration.

## Other bulletins for the same vehicles and component

- [SB2139001R2](/bulletins/10208328.md), 2022-02-28, Service bulletin: STEERING. Some versions of Model S and X front drive unit halfshafts might cause excessive vibrations during hard acceleration at higher ride height settings. This is exclusively an NVH issue and does not otherwise affect steering functionality, braking, or acceleration.
- [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\-32\-004](/bulletins/10177030.md), 2020-07-06, Service bulletin: STEERING. Some Model S and Model X vehicles might exhibit stiff steering due to corrosion at the lower steering column I\-shaft U\-joint.
- [SB\-18\-32\-002 R3](/bulletins/10153425.md), 2019-02-19, Service bulletin: STEERING:RACK AND PINION:RACK; STEERING. Long\-term exposure to high\-corrosion environments might weaken the bolts that attach the power steering motor to the steering rack housing.
- [SB\-18\-32\-002 R1](/bulletins/10143008.md), 2018-07-16, Service bulletin: STEERING. Long\-term exposure to high\-corrosion environments might weaken the bolts that attach the power steering motor to the steering rack housing.
