The short answer

NHTSA received Mack Trucks, Inc.’s report on Aug 18, 2015. Copied from NHTSA on Oct 25, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

If the air brake system reservoir has as insufficient volume, braking performance may be affected, increasing the risk of a crash.

Mack Trucks, Inc.

(Mack) is recalling certain model year 2011-2016 Granite (GU) trucks manufactured September 24, 2011, to July 1, 2015.

The affected trucks may be equipped with an air brake system reservoir that does not have a sufficient volume.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, “Air Brake Systems.”

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.
