Service bulletin SB2139001R2

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.

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
