REAR LIGHT MODULES (TAIL, REVERSE, BRAKE, SIGNAL) KEEPS ON FAILING. DEALER QUOTES INITIALLY $250 TO FIX/REWIRE BUT THEN GOES UP TO $950 TO REPLACE ECU. THIS IS FRUSTRATING AS THIS IS DRIVING HAZARD, OWNERS ARE LEFT WITHOUT MUCH CHOICE. I HAVE SEEN MULTIPLE COMPLAINTS OF THE SAME ISSUE SO MB SHOULD ALREADY KNOW THAT THIS PROBLEM EXISTS AND BE HONEST UPFRONT ABOUT IT. I HOPE NOBODY GETS HURT IF THE LIGHTS FAIL WHILE DRIVING THIS MODEL/BRAND.

WITHIN A SHORT PERIOD OF TIME AFTER GETTING THE CAR, WE ALSO FELT A STRONG JERKING THEN SHIFTING GEARS, BUT IT WAS DOING IT ON ITS OWN. WE TOOK IT IN AND WAS TOLD IT'S JUST LOUD. THEN WE WERE TOLD THERE WAS A RECALL. THEY WERE SUPPOSED TO FIX IT BUT IT NEVER STOPPED. THE CHECK ENGINE LIGHT CONTINUED TO COME ON. OTHER ISSUES RELATED TO THE ENGINE HAD TO BE FIXED RATHER QUICKLY. THE CAR WAS PURCHASED IN THE END OF 2005, AND HAS 88,000 MILES. OVER A YEAR AGO, THE CAR BEGAN IDLING/SHAKING REALLY BAD. I CALLED MB ROADSIDE AND WAS TOLD THAT IT WAS PROBABLY BECAUSE THE GAS CAP WASN'T PLACED BACK ON THE CAR CORRECTLY AND GAS WAS LEAKING. I HAD THE CAR CHECKED AND THERE WAS NO GAS LEAKING.

THE CAR IS STILL IDLING BAD AND CHECK ENGINE LIGHT IS ON. IT IS NOW BACK AT THE DEALERSHIP IT WAS PURCHASED FROM FOR A DIAGNOSIS, WHICH I SHOULD RECEIVE TOMORROW. *TR
