What is wrong
PACCAR Incorporated (PACCAR) is recalling certain 2027 Peterbilt 567, 579, 589 and 2027 Kenworth T680, T880, and W990 vehicles. The seat ventilation harness may be missing heat-shrink, resulting in a short circuit.
The risk
A short circuit increases the risk of a fire.
Why seat defects matter: Seat structure, latches and head restraints all contribute to protection in a collision, particularly from the rear.
The remedy
Dealers will replace the harnesses, free of charge. Owner notification letters were mailed October 16, 2026. Owners may contact Peterbilt's customer service at 1-940-591-4220 or Kenworth's customer service at 1-425-828-5888. PACCAR's number for this recall is 26PACE.
About the seats
Seat recalls cover the seat frame, recliners, track locks, head restraints and seat-mounted parts such as side air bags or occupant sensors.

What to do
- Enter your VIN in NHTSA’s lookup (below) to confirm that your vehicle is included and that the repair has not already been done.
- Call a dealer for the brand and book the repair. Quote NHTSA campaign 26V-544 and the manufacturer’s number 26PACE.
- If a seat or head restraint does not lock firmly, avoid using that position until the dealer has inspected it.
- Safety recall repairs are carried out free of charge by the manufacturer’s dealers. If you already paid for this repair yourself, ask the manufacturer about reimbursement and keep your receipt.
Check by VIN
A campaign rarely covers every vehicle of a model year. Enter your 17-character VIN to find the recall campaigns filed for your make, model and model year. The VIN is on the driver’s side of the dashboard (visible through the windshield), on the door-jamb label, and on your registration and insurance documents.
Is a recall still open on your vehicle? Only NHTSA’s official VIN check can say whether a campaign applies to your exact vehicle and whether the repair has already been done.
Your VIN is decoded with NHTSA’s public vPIC service to identify the make, model and year. It is not stored and is not added to any page address.
