408V465000 · Steering:hydraulic Power Assist:hose, Piping, And Connections
Sep 17, 2008
MERCEDES-BENZ IS RECALLING 125,228 MY 1998-2004 M-CLASS VEHICLES. THE HOSE CLAMP USED TO SECURE THE POWER STEERING FLUID COOLING HOSE TO THE POWER STEERING FLUID COOLER MAY NOT PROVIDE SUFFICIENT CLAMPING FORCE FOR THIS CONNECTION.
Consequence & remedy
Consequence: THE LOSS OF POWER STEERING FLUID MAY RESULT IN DIMINISHED POWER STEERING OVER TIME AND ULTIMATELY CAN DAMAGE THE POWER STEERING PUMP. THIS COULD RESULT IN A LOSS OF CONTROL AND A CRASH WITHOUT WARNING.
Remedy: AN EARLIER RECALL REPAIR PERFORMED ON THESE VEHICLES MAY NOT BE SUFFICIENT TO PREVENT A FUTURE LEAKAGE OR FAILURE OF THE POWER STEERING HOSE CONNECTION (PLEASE SEE 03V121). SINCE IT IS NOT POSSIBLE THROUGH INSPECTION TO IDENTIFY SPECIFIC VEHICLES THAT MAY NOT HAVE BEEN PROPERLY REPAIRED, ALL VEHICLES REPAIRED PRIOR TO NOVEMBER 15, 2003, WILL BE REPAIRED AGAIN. THE RECALL IS EXPECTED TO BEGIN DURING NOVEMBER 2008. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
