ON CERTAIN PASSENGER VEHICLES, FAILURE OF ONE OF THE SIDE BRAKE LIGHTS CAN OCCUR. THE BASE OF THE SOCKET CAN BE SUBJECT TO THERMAL DEFORMATION OVER TIME.

Consequence & remedy

Consequence: THIS DEFORMATION CAN CAUSE MOVEMENT IN THE SOCKET-TO-BULB CONNECTION, WHICH COULD LEAD TO A LOOSENING OF THE ELECTRICAL CONTACTS IN THE SOCKET, AND FAILURE OF THE BULB TO ILLUMINATE.

Remedy: DEALERS WILL REPLACE THE REAR LAMP MODULES. THE RECALL BEGAN ON SEPTEMBER 12, 2006, TO APPROXIMATELY 8,200 OWNERS. PHASE II MAILING IS SCHEDULE ON OR ABOUT NOVEMBER 3, 2006, AND PHASE III MAILING IS SCHEDULE FOR JANUARY 2007 FOR THE REMAINING OWNERS. OWNERS OF VEHICLES WITH THE UPDATED TRIM (POST-FACE LIFT) WILL GET AN INTERIM NOTICE DURING NOVEMBER 2006, ASKING THEM TO SCHEDULE AN APPOINTMENT FOR REAR TAIL LAMP REPLACEMENT LATER IN 2007. HOWEVER, IF THEY EXPERIENCE AN ACTUAL REAR LAMP FAILURE BEFORE THEY RECEIVE THAT NOTICE, THEY SHOULD COME TO THEIR DEALER IMMEDIATELY FOR A FREE REPAIR. OWNERS MAY CONTACT MERCEDES-BENZ AT 1-800-367-6372.
