What is wrong

PACCAR Incorporated (PACCAR) is recalling certain 2022 Kenworth T680, T880, and W990 vehicles. The HVAC controls may have insufficient soldering between the potentiometer(s) and the PCBA board, resulting in windshield defrost failure.

What can happen

Inoperative windshield defrost may reduce driver visibility, increasing the risk of a crash.

The remedy

Dealers will replace HVAC control head, free of charge. Interim owner notification letters were mailed on September 17, 2021. Remedy parts are expected to be available mid-June, 2022. Owners may contact PACCAR's customer service at 1-425-828-5888 (Kenworth). PACCAR's number for this recall is 21KWE.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
