PACCAR Incorporated: Engine
PACCAR Incorporated reported this defect to federal regulators on Feb 17, 2021 and put the number of vehicles at risk at 132. The repair is free for as long as the recall stands.
The defect
PACCAR Incorporated (PACCAR) is recalling certain 2021-2022 Kenworth T680, T880, W990, T800, W900 and Peterbilt 579, 567, 389, 367 vehicles equipped with a Cummins X15 engine. The capscrews that attach the flywheel to the crankshaft may have been improperly torqued, allowing the flywheel to detach.
The risk
A detached flywheel can cause loss of drive power, increasing the risk of a crash. Additionally, driveline pieces may be ejected from the engine compartment, increasing the risk of injury.
The remedy
PACCAR will notify owners, and dealers will properly torque the capscrews and the engine will also be inspected for damage and, if necessary, repaired, free of charge. The recall began on March 29, 2021. Owners may contact PACCAR customer service at 1-425-828-5888 (Kenworth) or 1-940-591-4220 (Peterbilt). PACCAR's numbers for this recall are 21KWA and 21PBB.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 21V080000.
