2013 MERCEDES-BENZ SPRINTER 3500 Complaints

BRAKE PEDAL IS SPONGY AND MUST BE PUMPED TO GET A FIRM PEDAL. I HAVE TAKEN IT TO THE DEALER TWICE AND COMPLAINED ABOUT THIS ISSUE, AND THEY TELL ME EVERYTHING IS NORMAL. WHEN YOU HAVE TO MAKE A SUDDEN SURPRISE STOP THE PEDAL GOES ALL THE WAY TO THE FLOORBOARD.

BRAKES ARE SOFT AND SPONGY. WHEN DEPRESSED, THE PEDAL WILL TRAVEL TO THE FLOOR MAKING IT DIFFICULT TO STOP. THE DEALER REPLACED THE MASTER CYLINDER AND BRAKE BOOSTER IN MARCH, 2015, BUT THAT DID NOT CHANGE THE OPERATION OF THE BRAKES. MY UNDERSTANDING FROM VISITING SEVERAL FORUMS IS THAT THIS A COMMON COMPLAINT FROM OTHER SPRINTER OWNERS, YET MERCEDES BENZ SAYS THEY HAVE NO KNOWLEDGE OF BRAKE ISSUES WITH THE VEHICLES. THE BRAKES ARE DANGEROUS AS THEY CURRENTLY OPERATE.

THE VALVES ON THE INNER REAR DUEL WHEELS BASICALLY CAN NOT BE CHECKED THROUGH THE VERY SMALL HOLES IN THE WHEEL COVERS OR EVEN WITHOUT THE WHEEL COVERS. I HAD, UPON DELIVERY OF THE SPRINTER, THE WHEELS REMOVED TO INSTALL METAL VALVE EXTENDERS SO I COULD REGULARLY CHECK TIRE PRESSURES. THIS IS A SAFETY ISSUE AS EXTREMELY DIFFICULT TO CHECK TIRE PRESSURES LEADS TO NO CHECKING, UNDER INFLATION AND ON ROAD TIRE FAILURE. THE SPRINTER 3500 SHOULD COME WITH FACTORY INSTALLED ACCESSIBLE VALVE EXTENDERS. I HAVE MET MULTIPLE SPRINTER DRIVERS WHO HAVE NEVER CHECKED THEIR REAR TIRE PRESSURES. *TR

VALVE STEM LOCATION MAKE PRESSURE SENSING AND AIR FILL NEAR IMPOSSIBLE ON REAR WHEELS. NO TMPS SYSTEM WHICH WILL RESULT IN HIGHER INCIDENCE OF LOW PRESSURE AND DANGEROUS DRIVING SITUATION LEADING TO ACCIDENTS. *TR *JS
