2016 MERCEDES-BENZ SPRINTER 3500 Complaints

ON SEPTEMBER 30, 2019, I WAS DRIVING DOWNHILL ON A MOUNTAIN ROAD WHEN OUR RV, A 25' LTV UNITY ON A MERCEDES SPRINTER 3500 CHASSIS, SUDDENLY LURCHED AND FELT OUT OF CONTROL. THE BREAKS AND STEERING WERE UNRESPONSIVE, AND I WAS PUMPING THE BREAKS, HARD! AFTER ABOUT 10 MINUTES OF STRUGGLING TO CONTROL THE VEHICLE AROUND A CURVEY DOWNHILL ROAD, CONTROL WAS RESTORED. LUCKILY, I WAS GOING SLOW ENOUGH THAT NO ACCIDENT RESULTED, BUT IT REALLY SHOOK ME! A COUPLE OF DAYS LATER THE VEHICLE (STILL UNDER WARRANTY) WAS LOADED ONTO A FLATBED TRUCK AND HAULED 2 HOURS AWAY TO KNOXVILLE, TN; THE CLOSEST MERCEDES SPRINTER VAN SERVICE CENTER. THEY REPLACED THE RIGHT REAR WHEEL SPEED SENSOR. I WAS TOLD THE OTHER SENSORS MIGHT ALSO FAIL, BUT THEY COULD NOT BE REPLACED UNTIL THEY FAILED. SINCE THEN, WE HAVE HEARD FROM SEVERAL OTHER RVERS WITH MERCEDES SPRINTER CHASSIS THAT THIS IS A COMMON PROBLEM. FOR US, THE VEHICLE NO LONGER FEELS SAFE TO TAKE ON THE ROAD SINCE WE HAVE NO IDEA WHEN THE NEXT SENSOR WILL FAIL. (PS - I TRIED TO SUBMIT THIS FORM EARLIER, BUT ACCIDENTALLY SELECTED 'I DO NOT WISH TO RECEIVE SAFETY RECALL ALERTS' - I DO WISH TO RECEIVE THOSE ALERTS.

WHEEL SPEED SENSORS KEEP FAILING. I HAVE HAD EIGHT SENSORS FAIL IN THREE YEARS OF OWNERSHIP. TRANSMISSION SHIFTS ERRATICALLY, SPEED SURGES, ABS, CHECK ENGINE LIGHT AND BRAKING IS IMPAIRED. THIS HAPPENS WHEN VEHICLE IS IN MOTION.

FOR THE THIRD TIME THE ESP AND ABS SYSTEM WARNING MESSAGE IS SHOWN, AT FIRST THE SPEED OF THE VEHICLE INCREASES, IN THIS CASE FROM THE SET 60 MPH TO 70, AT WHICH POINT I SHUT THE CRUISE CONTROL DOWN. FROM THEN ON FOR THE REST OF THE DAYS TRAVEL C.A.200 MILES AND FOR THE REST OF THE TRIP (450 MILES) CRUISE CONTROL WAS INOPERATIVE. EACH TIME IT HAPPENS A MECHANIC VISIT IS NECESSARY. THE VEHICLE IS A WINNEBAGO NAVION

I OWN AN RV ON A MERCEDES 3500 SPRINTER CHASIS. I HAVE EXPERIENCED NUMEROUS FAILURES THAT CAUSE THE RV TO SPEED UP RAPIDLY AND I HAVE TO TAKE EMERGENCY ACTION TO AVOID AN ACCIDENT. USUALLY, I SHIFT INTO NEUTRAL TO DISENGAGE THE TRANSMISSION. I HAVE ~43,000 MILES ON MY RV AND I HAVE EXPERIENCED THIS ISSUE AND MERCEDES HAS REPLACED THE WHEEL SENSORS 6 DIFFERENT TIMES. ALL MAINTENANCE PERFORMED ON THE VEHICLE HAS BEEN PROVIDED BY A MERCEDES DEALER SERVICE CENTER. DOESN'T SEEM TO MATTER IF I AM DRIVING ON THE FREEWAY OR CITY STREETS, WHEN THE FAILURE HAPPENS, THE VEHICLE STARTS TO ACCELERATE RAPIDLY, RPMS SKYROCKET, THE DASHBOARD GETS THREE TROUBLE INDICATOR LIGHTS THAT COME ON, THE CHECK ENGINE LIGHT COMES ON. I AM PICKING UP THE VEHICLE FROM THE LOCAL MERCEDES DEALER TODAY AFTER JUST HAVING ANOTHER SENSOR FAILURE. I WAS DRIVING ON I-10 WHEN THE MOST RECENT FAILURE OCCURRED. THE VEHICLE BEGAN TO ACCELERATE, RPMS WENT VERY HIGH. VERY SCARY SITUATION. THE "WHEN DID THIS HAPPEN" DATE I'VE ENTERED IS FOR THE MOST RECENT FAILURE. I HAVE EXPERIENCED THIS ISSUE NUMEROUS TIMES.

DRIVING ON A DRY DAY, SMOOTH ROAD, WITH CRUISE CONTROL ON 65MPH AT 7:45PM. THIS VEHICLE IS CONVERTED WITH A THOR 24HL CAMPER ON THE CHASSIS. FIVE HOURS INTO THE DAYS DRIVE THE VEHICLE FLASHED ASR/ESP TRIANGLE - AND JERKED ABRUPTLY BUT INSTANTANEOUSLY BUT REMAINED ON CRUISE CONTROL. 2 SECONDS LATER: ABS LIGHT ON, ASR/BAS LIGHT ON, ESP LIGHT ON CRUISE CONTROL STOPPED FUNCTIONING (FYI - A VERY HEAVY ACCELERATOR PEDAL SPRING MAKES DRIVING DIFFICULT, FOR HOURS ON END, WITHOUT CRUISE WORKING - ESPECIALLY FOR THE OLDER DRIVERS LIKELY TO BE DRIVING THIS RIG.) PULLED OFF THE SIDE OF THE ROAD, SET FLASHERS, AND TURNED OFF ENGINE FOR ONE MIN HOPING TO RESET THE FAULT. TURNED BACK ON - NO CHANGE OFF THEN BACK ON AND THE YELLOW CHECK ENGINE CAME ON STEADY ALONG WITH THREE PREVIOUS AUCTION LIGHTS (ABOVE) VEHICLE HAD EXPERIENCED (WITH THE PREVIOUS OWNER) A PREVIOUS 'WHEEL SPEED SENSOR FAILURE' AND IT WAS REPAIRED. . 'WHEEL SPEED SENSOR FAILURE' APPEAR AT EPIDEMIC LEVELS ON THE TWO RV FACEBOOK GROUPS ASSOCIATED WITH THIS VEHICLE. THE 5TH KEY TURN AFTER INITIAL FAULT AND FAILURE OF CRUISE CONTROL THE THREE LIGHTS WENT OUT BUT THE CHECK ENGINE LIGHT REMAINED ON. ON APPROXIMATELY THE TENTH KEY TURN THE CHECK ENGINE LIGHT WENT OUT. VEHICLE RETURNED FOR SERVICE AT MERCEDES DEALERSHIP 'UNDER WARRANTY'. MY ISSUE LAYS IN THE POTENTIAL FOR THE VEHICLE TO ENTER INTO THE LIMP MODE IF ANOTHER CENSOR SHOWS A FAULT AND I'M ON THE ALASKA HIGHWAY 200 MILES FROM THE NEAREST POSSIBLE SERVICE. DEALER REFUSES TO SHARE TECH DATA CONCERNING RESET OF FAULT CONDITION OR A MERCEDES FIX FOR THIS NOW WELL KNOWN AND DOCUMENTED VEHICLE SHORTCOMING. THIS ISSUE CAN AND WILL GET PEOPLE KILLED AS THEY 'LIMP' DOWN THE HIGHWAY TO GET SERVICED OR ARE FORCED TO PULL OVER IN HEAVY TRAFFIC TO CHECK OUT WHAT MERCEDES SHOULD BE WARNING IS ALL ABOUT PROACTIVELY.

I HAVE HAD TO REPLACE OUT OF POCKET ALL FOUR BRAKE SPEED SENSORS WHILE THEY SHOULD HAVE BEEN COVERED UNDER WARRANTY. MY LOCAL MERCEDES DEALER EVENTUALLY ACKNOWLEDGED THIS, BUT WILL NOT REIMBURSE SINCE THEY DID NOT REPLACE THEM. THIS ALL HAPPENED BETWEEN 17 AND 21,000 MILES AND CREATED UNSAFE DRIVING CONDITIONS.

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.

BOTH LEFT AND RIGHT REAR WHEEL SPEED SENSORS FAILED RESULTING IN TRANSMISSION LIMITED TO 2ND GEAR AND BACK UP. VEHICLE HAS DRIVEN 9800 MILES TOTAL.

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.
