What’s wrong with it?

If the rear brakes overheat there would be an increased risk of a tire blowout or a wheel-end fire.

Mack Trucks, Inc.

(Mack) is recalling certain model year 2010-2016 Granite 4X2 trucks manufactured September 17, 2009, to July 31, 2015.

Due to a brake imbalance between the steer and drive axle brakes, the rear brakes may overheat.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
