Defect: PACCAR Incorporated (PACCAR) is recalling certain 2018 Kenworth T680 and T880, and Peterbilt 567 and 579 trucks. The seat belt buckle assemblies on these vehicles may have been glued and not sewn during manufacturing, possibly causing the assembly to come apart under load, such as in the event of a crash.

Consequence: If the seat belt buckle assembly separates, it can prevent the occupant from being properly restrained in the event of a crash, increasing the risk of a crash.

Remedy: PACCAR will notify owners, and dealers will replace the seat belt buckle assemblies that were not sewn, free of charge. PACCAR issued owners an interim notification on February 4, 2019.

18V816000

Date: 2018-11-16. Systems: EXTERIOR LIGHTING.

Defect: PACCAR Incorporated (PACCAR) is recalling certain 2013-2019 Kenworth T680 and T880 and Peterbilt 579 trucks, greater than 30 feet long and equipped with side extender mounted intermediate marker lamp/turn signals that do not include a reflex reflector. Since both intermediate side marker lamps and reflex reflectors are required, these vehicles fail to comply with the requirements of Federal Motor (excerpt)

Consequence: Missing reflex reflectors can reduce the vehicle's visibility to other drivers, increasing the risk of a crash. (excerpt)

Remedy: PACCAR will notify owners and dealers will install reflex reflective tape, free of charge. The recall began January 15, 2019. Owners may contact PACCAR customer service at 1-918-259-3258. PACCAR's number for this recall is 18KWF, and 18PBC. (excerpt)

18V657000

Date: 2018-09-21. Systems: ENGINE AND ENGINE COOLING.

Defect: PACCAR Incorporated (PACCAR) is recalling certain 2017-2019 Kenworth C500, T600, T660, T680, T800, T880 and W900 trucks, as well as Peterbilt 367, 386, 389, 567, 579 and 587 trucks, equipped with Cummins ISX15 or X15 diesel engines. In certain driving conditions, such as on a long down-hill grade, the fuel line may burst if the fuel pump cooling circuit screen becomes restricted.

Consequence: If the fuel line bursts, fuel may leak onto the road resulting in a roadway hazard for other motorists. The engine may also stall without warning, resulting in the vehicle's inability to restart, increasing the risk of a crash.

Remedy: Cummins will notify owners, and dealers will replace the suspect fuel pump cooling circuit screen, free of charge. The recall began November 21, 2018. Owners may contact PACCAR customer service at 1-940-591-4220. PACCAR's number for this recall is 18E081.

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
