# Service bulletin N182188440

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.

- Published by NHTSA: 2022\-02\-07

## NHTSA's summary

Customer Satisfaction Program. Certain vehicles may have an incomplete or missing braze between the harness bulkhead support bracket and the fuel rail assembly. If the braze is incomplete the support bracket may detach from the fuel rail assembly over time. Wiring may sever and compromise the function of the fuel pump and/or the 4 passenger side injectors. If the function of the fuel pump and/or injectors is compromised, the Check Engine Light will come on, and you could experience reduced engine power. Loss of propulsion is possible, and there is a remote chance of fire if there is a fuel leak. Replace fuel rail assembly.
