1,100 Peterbilt and Kenworth Trucks Recalled Due to Faulty Methane Gas Detection System

Bellevue, WA — PACCAR Incorporated has announced the recall of certain Kenworth and Peterbilt vehicles due to an electrical malfunction that causes the methane detection system to fail.

PACCAR alerted the National Highway Traffic Safety Administration (NHTSA) of the issue in late December 2021, according to documents submitted.




 

According to PACCAR, the recall affects 33 models which include certain 2016-2022 Peterbilt 567, 579, 2021-2022 Peterbilt 536, 2017-2021 Kenworth T880, 2016-2022 Kenworth T680, 2018-2020 Kenworth T440, 2020 Kenworth T270, and 2021 Kenworth T280 vehicles.

In affected vehicles, the methane detection system will not function if the system loses power, the company stated.

The vehicle’s operator may be unaware of a system malfunction or the presence of excessive methane levels, thus increasing the risk of injury or fire.

 

The methane detection warning alarm and warning lamp share the same fuse, PACCAR explained.

Absent a redundant power source, the warning lamp and the warning alarm will not operate to produce a constant warning sound and light when the methane detection system loses power.

A faint smell may indicate the presence of excessive levels of methane gas in CNG trucks, PACCAR alerted.




 

PACCAR estimates approximately 1,107 units are affected.

As a remedy, dealers will provide a redundant power source for the wiring alarm and light by moving the signal for the warning alarm from a shared fuse to the battery splice block in the cab harness, free of charge.

Owners who previously incurred costs to obtain a remedy for the same issue may seek reimbursement, the company stated.

Owner notification letters are expected to be mailed on February 26, 2022.

 

Owners may contact Peterbilt customer service at (940) 591-4220 and Kenworth customer service at (425) 828-5888, respectively.

PACCAR’s numbers for this recall are 21KWH (Kenworth) and 21PBN (Peterbilt).
