  76. Secondary hood latch bolts may loosen

    Reported November 6, 2012Model years 2012NHTSA campaign 12V53300023 vehicles affected

    Loose striker bolts could make the secondary hood latch ineffective. If the primary lock fails or the hood is not properly closed, the hood could open while driving and increase crash risk. Dealers will check and retighten the bolts as needed.

    Official NHTSA recall text
    Component
    LATCHES/LOCKS/LINKAGES:HOOD:LATCH
    Defect
    Mercedes-Benz is recalling certain model year 2012 CLS550 and CLS550 4Matic vehicles, manufactured December 01, 2011, through December 13, 2011. The bolts that hold the hood's secondary latch striker may have been insufficiently tightened.
    Consequence
    The reduced torque of the striker bolts might lead to a loosening of the bolts. If two of the four bolts securing the striker became loose, the secondary hood latch function would become ineffective. If this problem combines with a failure of the primary hood lock or if the hood is not properly closed, the hood could open while driving, increasing the risk of a vehicle crash.
    Remedy
    Mercedes-Benz will notify owners, and dealers will check and retighten the bolts as necessary. Mercedes-Benz notified the owners by phone for this campaign starting on 11/21/2012. Owners may contact Mercedes-Benz at 1-800-367-6372.

  82. Brake pedal may require more effort

    Reported July 27, 2005Model years 2001–2005DVSA recall R/2005/056174,066 vehicles affected

    Vibrations may wear contacts in the brake control unit, increasing resistance and the effort needed on the brake pedal to stop the vehicle. An additional bracket will be fitted to prevent movement of the electrical harness.

    Official DVSA recall text
    Component
    BRAKE PEDAL MAY REQUIRE MORE EFFORT THAN EXPECTED
    Defect
    In isolated cases it is possible for vibrations within the vehicle to in turn vibrate the wiring harness connected to the Sensotronic Brake Control unit. This causes the internal contacts within the unit to suffer abrasion and subsequent resistance increase. The resultant affect is that more effort will be required on the brake pedal to stop the vehicle.
    Remedy
    Recall the vehicles that are likely to be affected and mount an additional bracket to the electrical harness to prevent relative movement.
  83. Brake system may switch to hydraulic backup mode

    Reported April 1, 2005Model years 2006NHTSA campaign 05V133000204,000 vehicles affected

    A wiring connection may deteriorate or the hydraulic pump may fail, causing the brake system to switch to backup mode. The vehicle can still be stopped, but the pedal will travel farther and require more pressure. Dealers will install a bracket and ground wire on all vehicles and inspect and replace the pump on some, free of charge.
