The short answer

NHTSA received MACK TRUCKS, INC’s report on Oct 18, 2012. Copied from NHTSA on Oct 20, 2026.

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

What’s wrong with it?

If the control box loses ground, it may have localized overheating. This could lead to a vehicle fire.

Mack Trucks is recalling certain model year 2008-2009 GU, LEU, and MRU trucks, manufactured from December 12, 2007, through May 8, 2008 and equipped with a certain focal mounted retarder control box.

The control box may lose its electrical ground.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
