Service bulletin SB2139001R3

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

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.
