Service bulletin K0B-CPOR-032819

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

Dealer Letter: **Part deployment details** In an effort to assist dealers in performing campaign K0B on a customer?s first visit, Toyota is deploying stock of EPT Sealers, part numbers 88278-0C010 and 88278-0C020 to all dealers. Dealers will receive enough parts to repair 2 days-worth of their peak demand based on the quantity of vehicles registered in their area.
