The defect
Mack Trucks, Inc. (Mack) is recalling certain model year 2014-2015 CXU trucks manufactured June 1, 2013, to November 28, 2014. These trucks may be equipped with an 88 liter air reservoir for the brakes instead of a 96 liter air reservoir. The lower volume of air may result in increased distances being needed to stop the truck. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard No. 121, "Air Brake Systems."
The risk
If the truck unexpectedly requires extra distance to stop, there is an increased risk of a crash.
