Recall 15V051 covers 106 2015 Kenworth trucks for loose brake caliper bolts. Repair will be free at any franchised Kenworth dealer once available.

Kenworth is recalling 106 2015 T660, K370, K270, T800, and T880 trucks because the brake caliper bolts were not properly torqued. If those bolts loosen, braking effectiveness drops and crash risk rises; the dealer repair will be free once the remedy is available.

What's wrong?

The disc brake caliper is the clamp that presses the brake pads against the rotor when the driver applies the brakes. On 2015 Kenworth T660, 210, K370, 320, K270, 220, T800, and T880 trucks in this recall, bolts hold that caliper in the correct position on the brake assembly. Those bolts need the correct torque, or tightening force, to keep the caliper secure under braking load.

The problem started at the factory when the right hand brake caliper torque tool was taken out of service. The left hand tool was used for both sides, but it did not record right side torque data. As a result, bolts were installed without confirmed correct torque, and loose bolts can let the caliper shift upward, contact the inside wheel surface, lock the wheel, or damage the tire valve stem.

There is no warning sign before failure. The recall information does not identify a warning light, sound, or pedal change that alerts the driver before the caliper bolts loosen enough to let the caliper move.

Who's affected?

Covers eight Kenworth and Peterbilt truck models from the 2015 model year, all tied to the same brake system caliper component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

Loose brake caliper bolts can reduce braking effectiveness and increase the risk of a crash. If your VIN is included, drive cautiously and contact a Kenworth dealer for instructions if braking performance changes. Repair will be free at any franchised Kenworth dealer once available.

What should I do?

  1. Check your VIN to confirm your 2015 Kenworth T660, 210, K370, 320, K270, 220, T800, or T880 is included in this recall.
  2. Watch for the owner notice from Kenworth before scheduling repair work if your dealer says the remedy is not open for your VIN.
  3. Contact a franchised Kenworth dealer with recall number 15V051 to ask about the free brake-caliper-bolt inspection and repair.
  4. Bring the recall notice if you have it, and ask the dealer to inspect, tighten, or replace loose caliper bolts that reduce brake effectiveness.
  5. Drive cautiously until the repair is complete. Leave extra following distance and avoid hard braking when you can.

What happens at the repair

Kenworth lists this remedy as under development. Once the dealer repair is available, a Kenworth technician will inspect the brake caliper bolts, tighten any loose bolts, and replace bolts that cannot be secured properly. The final repair will be free under the recall once it opens. Kenworth has a general reimbursement plan on file for owners who already paid for a related repair. Keep repair orders and payment records, and ask customer service or the service desk how to submit documentation.
