# Service bulletin 20PBA

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

Safety Recall Interim Bulletin: Peterbilt has decided that a defect, which relates to motor vehicle safety, may exist in certain Model 365, 389, 567, and 579 vehicles manufactured between April 18, 2014 and September 30, 2019 with a left\-hand under hood jumper start terminal. Your vehicle may have jumper terminal battery cables that are too long, or are eligible for improved routing. Battery cables that are too long may chafe against the left front suspension leaf spring, which could cause a short circuit, fire under the hood, or increased risk of crash.
