# Service bulletin LTT031522

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

TT: Some 2022MY Lexus drivers may experience the inability to perform Service Bulletin Titled ?Head Unit Software Update \(Panasonic\)? on their vehicle due to gradual roll out of this customer facing update. This phased roll out means that as time progresses, more vehicles will receive the update notification and ability to update the head unit. This timing will vary by location and may not display for every vehicle in one location at the same day/time
