Service bulletin ATC2333A

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

This ATC is being issued to offer eligible customers an opportunity to receive a refund instead of a fuel heating solution being developed by Cummins for future installation. Upon receiving a signed agreement from the appropriate party in authority with respect to the eligible engine(s), service providers may offer the customer a refund per eligible engine in a manner agreed to by both the customer and the service provider. This is an update to a previously submitted communication.
