JUNE 2009 -- Mack is recalling 338 model year 2009 MRU and LEU heavy duty trucks manufactured from August 20 through November 26, 2008 equipped with certain Haldex quick release valves (QRV). The rubber diaphragm inside the QRV may experience delamination resulting in significant levels of air pressure leakage past and/or through the diaphragm, or the development of a bubble in the diaphragm which may trap air pressure in the valve and not allow the service brakes to release. Malfunction of the air brake system could result in a vehicle crash. Mack will notify owners and repair the affected vehicle free of charge. The safety recall is expected to begin on or about July 13, 2009. 09V-194

The axle beam may have transverse shear lines on the bottom of the axle from the trimming process. These lines, if present, can promote initiation of cracks, which over time may possibly lead to axle beam failure and a vehicle crash can occur. Mack will notify owners, inspect and replace any affected axle beams free of charge. The safety recall is expected to begin duringJuly 2009.  09V-240

DECEMBER 2008 -- Mack is recalling 34,269 MY 1999-2005 CX and MY 2004-2008 CXN trucks. The headlight switch may prematurely fail resulting in inoperative or intermittent headlights.

This could impair a driver's visibility, increasing the risk of a crash. Dealers will replace the headlight switch. The recall is expected to begin on or about February 27, 2009.  08V-688
