Western Star 4900 Recall 18V351: Front brake hose can chafe, causing air loss and reduced braking

NHTSA campaign 18V351, reported May 29, 2018, 640 vehicles potentially affected.

What this recall means for you

Some 2012-2019 Western Star 4900 trucks may have too little clearance between the front brake hose and the hood. Over time, the hose can rub against the hood and become chafed.

If the hose chafes, it can lose air pressure, which may reduce braking effectiveness and increase the risk of a crash.

Daimler Trucks North America will notify owners, and authorized dealers will replace the front axle brake hose free of charge. Owners can contact DTNA customer service at 1-800-547-0712 (recall FL-773), and should check their VIN for open recalls.
