Bulletin Summary
Safety Recall: INTERIM NOTIFICATION - Peterbilt Motors Company has determined that a defect, which relates to motor vehicle safety, exists in certain model year 2017, 2018, 2019 and 2020 Model 520 vehicles manufactured between October 17, 2016 and March 04, 2019 with left hand or right hand single steer Power Distribution Center (PDC) harnesses. The power wire to the PDC may be inadequate and unable to accommodate the current draw. This can cause the wire to overheat and potentially melt the cab power harness connector. This could cause a loss of power to the cab and engine, which may result in the engine shutting down. A sudden loss of engine power could increase the risk of a crash.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
