20180805FUEL/PROPULSION SYSTEM
THE FUEL FILTER HAS A CRACK THAT RESULTS IN LEAKING GASOLINE WHEN THE FUEL TANK IS FULL. I FOUND THAT THERE IS A RECALL FOR 2011 GLKS ALREADY IN PLACE FOR THIS ISSUE, BUT OUR GLK WAS BUILT A FEW MONTHS PRIOR TO THOSE REPORTED AS AFFECTED. HOWEVER, I AM CERTAIN THIS IS THE SAME ISSUE WITH OUR VEHICLE BASED ON THE DESCRIPTION OF THAT RECALL. NHTSA ID: 12V557000. IF THERE ARE OTHER SIMILAR ISSUES WITH THE SAME EXACT MODEL YEAR CAR, JUST DIFFERENT BUILD DATES, I BELIEVE THIS SHOULD BE COVERED BY THE RECALL. HOWEVER WHEN I CALL DEALERSHIPS WITH MY VIN THEY DENY THAT RECALL EXISTS.
