I WAS DRIVING DOWN RT 70 IN MARLTON, NJ ON MONDAY MAY 7, 2012 WHEN EVERY LIGHTS IN MY CAR LIT UP. I THEN TOOK IT TO MERCEDES AT APPROXIMATELY 1:00 P.M. I SAT THERE WAITING FOR THEM TO TELL ME WHAT WAS GOING ON. I DECIDED AT 1:50 TO FIND OUT AND I WAS TOLD BY MY SERVICE TECH DAN SWUWEK THAT IT WAS AN ELECTRICAL PROBLEM AND THAT HE DID NOT KNOW HOW LONG IT WOULD BE TO FIX IT. I HAD TO GET A RENTAL. HE CALLED ME THE NEXT DAY AND INDICATED THAT A PART WAS ORDERED. I THEN CALLED HIM BACK LATER IN THE DAY WHEN HE SAID THAT IT WAS NOT THE PART T…

SIMILAR TO OTHER COMPLAINTS THAT HAVE BEEN FILED AGAINST MERCEDES, IT SEEMS AS THOUGH THE ELECTRICAL CONNECTION TO MY REAR RIGHT LIGHT (BRAKE LIGHT, RUNNING LIGHT, TURN SIGNAL, ETC.) HAS MELTED AND IS NO LONGER OPERATIONAL. THE ENTIRE LIGHT IS OUT AND I GET WARNING MESSAGES ON THE DASH ABOUT THE PROBLEM. IT LOOKS LIKE THIS IS THE SAME PROBLEM THAT EVERYONE ELSE WITH THE SAME MAKE/MODEL AS ME ARE HAVING. HOPEFULLY MERCEDES RECOGNIZES THE SCALE OF THIS FLAW IN THEIR ENGINEERING AND SENDS OUT A RECALL SOONER THAN LATER. *TR

Owner report 10562556 · 2014-02-02 (February 2, 2014)
ALL BULBS ON THE RIGHT SIDE TAIL LIGHT ARE NOT WORKING, THAT INCLUDES BRAKE LIGHT, REVERSE LIGHT, AND SIGNAL LIGHT. I THOUGHT THE BULBS WERE OUT BUT WHEN I WENT TO CHANGE THE BULBS THEY WERE ALL FINE. WHAT I DID NOTICED WAS THE BROWN WIRE WAS BURNT AND SO WAS THE PLASTIC THAT HOLDS THE WIRES TOGETHER, IT SEEMED LIKE THAT ENTIRE SIDE WAS BURNT AND EVEN MELTED. THIS SEEMS TO BE AN ELECTRICAL PROBLEM AND IT ALSO SEEMS TO BE A SAFETY HAZARD. I SPOKE TO ONE OF MY MECHANIC FRIENDS WHO SUGGESTED I BRING THE CAR BACK TO THE DEALER TO TRY AND RESOLV…
