2016 MERCEDES BENZ SPRINTER 3500 Service Brakes Problems

REAR WHEEL SPEED SENSOR HAD TO BE REPLACED AT 30,000 MILES AND NOW BOTH FRONT WHEEL SENSORS ARE FAULTY AT 50.000 MILES. IN MY READING THIS IS A COMMONLY FAULTY PART AND IT COST $ 760.00 TO REPLACE BOTH SENSORS. FORTUNATELY THE FIRST SENSOR WAS UNDER WARRANTY. IT WOULD BE GREATLY APPRECIATED IF YOU WILL LOOK INTO THIS ISSUE. BECAUSE YOU CANNOT AFFORD TO TRADE AN RV. I WAS ON A TRIP WHEN THE INDICATOR LIGHTS CAME ON ON DASH AND I WAS ABLE TO DRIVE 7 HOURS HOMES. MY OWNERS MANUAL EXPRESSED I SHOULD SEEK TECHNICAL ASSISTANCE ASAP.

WHEN I WENT TO TRY THE 4 WHEEL DRIVE THE FOLLOWING THINGS HAPPENED: A CLUNKING SOUND IN THE REAR OF THE VEHICLE. NUMEROUS WARNING LIGHTS CAME ON . ABS, COLLISION AVOIDANCE, CRUISE CONTROL, CHECK ENGINE, ESC OR ESP. OVER TIME THE LIGHTS CLEARED BUT CAME BACK ON WEEKS APART. I AM A RETIRED NASA SAFETY/RELIABLY ENGINEER. IN MY OPINION ALL OF THESE LIGHTS COME ON AS A RESULT OF FAILURES OF ONE OR MORE WHEEL SPEED SENSORS. THIS IS A MAJOR SAFETY PROBLEM AS WHEN THERE IS A FAILED OR INTERMITTENT OPERATION OF A FAILED SPEED SENSOR. ALL OF THESE SAFETY SYSTEMS FAIL WHEN THE ONE SENSOR FAILS. THIS FAILURE COULD OCCUR UNEXPECTEDLY AT ANY TIME. LEADING TO LOSS OF LIVES AND VEHICLE. I HAVE NOT RECEIVED ANY WARNING LETTERS ON THIS MAJOR SAFETY FAILURE. ACCORDING TO THE DEALER MERCEDES IS AWARE OF THIS ISSUE. AFTER THE VEHICLE IS OUT OF WARRANTY MERCEDES SAYS THEY WILL CHARGE THE OWNER TO FIX IT. AT THE VERY LEAST THE ISSUE CLEARLY NECESSITATES THAT THIS ISSUE BE ELEVATED, TO CONSUMERS, AND THAT THE ISSUE BE FIXED . A WARNING THAT DESCRIBES THE ISSUE AND MERCEDES STATUS ON A FIX SHOULD GO OUT TO ALL THE APPROPRIATE PARTIES IMMEDIATELY. THE VEHICLE WAS STOPPED PUT IN NEUTRAL THEN 4 WHEEL DRIVE WAS ENGAGED, IMMEDIATELY WHEN MOVING THERE WAS A BIG CLUNK AND THE WARNING LIGHTS CAME ON. THEY WENT OUT THEN CAME BACK ON INTERMITTENTLY FOR MONTHS. ONE TIME THEY CAME ON JUST SITTING AT THE LIGHT. FAILURE OF MULTIPLE SAFETY SYSTEMS DUE TO A SENSOR FAILURE IS UNACCEPTABLE. I BELIEVE A DESIGN FIX IS URGENTLY NEEDED AND SHOULD BE PRESSED FOR HARD BY THE GOVERNMENT. CURRENTLY THERE IS NO FIX. AND MERCEDES IS NOT ADEQUATELY WARNING THE PUBLIC OF THE ISSUE. UNTIL I PRESSED MERCEDES HARD ON THIS INTERMITTENT PROBLEM I WAS NOT MADE AWARE OF WHAT EXACTLY THE PROBLEM WAS. THE FAILURE OF ONE SENSOR SPEED CAUSES MULTIPLE SAFETY SYSTEMS TO NOT WORK.

THIRD-TIME SPEED SENSOR FAILED WHILE DRIVING ' ALL 3 TIMES WHILE DRIVING ON HIGHWAY. CAUSES THE VEHICLE TO SPEED UP / SLOW DOWN AND LURCH WITH THE ENGINE DOING HIGH REVS. CRUISE CONTROL BECOME INOPERABLE. ABS, FORWARD COLLISION, AND PARKING SENSORS BECOME INOPERABLE. BRAKES PERFORM ERRATICALLY FOR SEVERAL MOMENTS AND THEN ABS INDICATES IT IS INOPERABLE. VAN BECOMES HAZARDOUS TO DRIVE WHILE THE ELECTRONICS ATTEMPT TO SORT OUT WHAT IS GOING ON. VERY GLAD I WAS NOT IN CONGESTED TRAFFIC EACH TIME THIS HAPPENS AS THE VAN BECOMES UNSTABLE. M-BENZ SOLUTION IS TO REPLACE SENSOR ' THIS DOES NOT SEEM SAFE NOR VIABLE LONG TERM FIX.

HAD TO SLAM ON BRAKES TO AVOID HITTING A CAR THAT PULLED OUT IN FRONT OF ME AS I APPROACHED A RED LIGHT. REAR PASSENGER BRAKE LINE FAILED AS A RESULT OF THE STOP. PUMPING BRAKES RESULTED IN FLUID BEING PUMPED OUT OF THE LINES.

THE VEHICLE HAS EXCESSIVE BRAKE PEDAL FREE-PLAY TRAVEL BEFORE BRAKING OCCURS. ALTHOUGH THE MANUFACTURER'S OWNERS MANUAL WARNS AGAINST PUMPING THE BRAKE PEDAL TO STOP THE VEHICLE, IT IS IMPERATIVE TO DO SO ESPECIALLY IN AN EMERGENCY SITUATION. IF THE DRIVER HAS TO HESITATE TO MAKE A DECISION ON WHETHER TO BRAKE OR ACCELERATE, THE FREE-PLAY TRAVEL WILL NOT ALLOW THE DRIVER ENOUGH TIME TO BRAKE SAFELY. THE VEHICLE IS DIFFICULT TO BRING TO A SAFE STOP UNLESS THE BRAKE PEDAL IS PUMPED AT LEAST TWO PUMPS BEFORE IT FEELS LIKE AND BRAKES LIKE A NORMAL SYSTEM. THE EXISTENCE OF THIS CONDITION WAS CONFIRMED BY A LOCAL MERCEDES DEALERSHIP TECHNICIAN. HIS RESPONSE WAS, "THIS IS NORMAL FOR THE 1-TON CHASSIS TO HAVE A SOFT, SPONGY PEDAL AND MAY GO TO THE FLOOR BEFORE THE BRAKE GRABS, BUT IN A EMERGENCY SITUATION IT WILL STOP EVEN IF THE PEDAL IS ALMOST TO THE FLOOR."
