Peterbilt Motors Co. is recalling four model years of its Model 520 used for refuse collection and in off-highway construction. The recall is due to melted wires that can lead to a stall and crash.
The connector between the cab power harness and the power distribution center harness may overheat and melt because of undersized wires, Peterbilt told the National Highway Traffic Safety Administration.
Peterbilt engineers learned of a melted connector in August 2018. A subsequent engineering analysis led to a production change in March.
The NHTSA filing mentioned no crashes or injuries. A Peterbilt spokesman declined comment.
Peterbilt, a division of Paccar Inc., will replace the main power wire to the power distribution center for free in 5,051 Model 520 trucks from the 2017-2020 model years. All the recalled trucks could have the condition.
Customers will get recall notifications June 3. The NHTSA recall number is 19V-282.
