Service bulletin SB 21 31 002

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-23-00-0062023-11-27. Service bulletin. Some model year 2021-2023 Model S Plaid and Model X Plaid vehicles running a vehicle software version earlier than 2023.44 may require a vehicle software update to address a mild vibration felt from the accelerator pedal and steering yoke/wheel that may occur during acceleration. This behavior does not affect the operation or safety of the vehicle. The software update adjusts certain motor controls during acceleration that may reduce the vehicle's rated range by up to 2 miles (3.2 km).
