2015 MERCEDES-BENZ B-CLASS ELECTRIC Complaints

TL* THE CONTACT OWNS A 2015 MERCEDES BENZ B-CLASS ELECTRIC. WHILE DRIVING AT 35 MPH, THE VEHICLE DECELERATED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN PERFORMED A SOFTWARE UPDATE ON THE VEHICLE. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 4,500. THE VIN WAS NOT AVAILABLE.

WHILE DRIVING 35 MPH ON TIMED LIGHT RUSH HOUR TRAFFIC ROAD, CAR LOST ACCELERATION CAPABILITY. INSTRUMENTATION PANEL DISPLAYED NORMALLY. CAR DID NOT RESPOND TO SWITCH TO SPORT MODE IN ATTEMPT TO GET MORE RESPONSE. DID NOT STALL COMPLETELY BUT NO ACCELERATION POSSIBLE. NORMAL AFTER TURNED OFF AND RE-START.

MY 2015 MERCEDES BENZ B CLASS ELECTRIC DRIVE LOST POWER DURING MY EVENING COMMUTE TODAY LEAVING ME STALLED IN TRAFFIC. I WAS NOT ABLE TO MAKE IT ACROSS ALL 5 LANES OF A BUSY FREEWAY TO THE SHOULDER BEFORE COMING TO A COMPLETE STOP HALFWAY BETWEEN TWO LANES (ONE OF WHICH WAS A BUSY MERGE LANE FROM SFO AIRPORT). I TRIED TO RESTART IT (KEYLESS) A COUPLE OF TIMES WITHOUT SUCCESS- NO MESSAGES ON DASH, REST OF ELECTRONICS (RADIO ETC) STILL WORKING FINE. I DID NOTICE THAT THE GAUGE DROPPED DOWN TO FULL "CHARGING" AS IF THE REGENERATIVE SYSTEM WERE FULLY ENGAGED BUT NOT ALL THE WAY TO OFF WHICH SEEMED ODD. I HIT THE SOS/ASSISTANCE BUTTON TO ASK THEM TO SEND CHP SINCE I WAS BLOCKING TRAFFIC AND GENUINELY FEARED FOR MY SAFETY. WHILE ON THE PHONE WITH THEM SOME GUYS STOPPED AND TRIED TO PUSH ME TO THE SHOULDER SINCE I WAS ONLY 3/4 OF A LANE AWAY BUT THE CAR WOULD NOT MOVE AT ALL. SHORTLY AFTER THEY GAVE UP, I RANDOMLY TRIED TO START THE CAR AGAIN AND IT DID START. I WAS ABLE TO PULL TO THE SHOULDER AND CALL OFF CHP. AFTER COLLECTING MY NERVES A BIT I HEADED FOR THE NEXT OFF RAMP AND MADE IT THE REST OF THE WAY HOME ON SURFACE STREETS WITHOUT INCIDENT. I WILL BE TAKING THE CAR TO THE DEALER IN THE MORNING.

THUMP! COMPLETE LOSS OF POWER ON FREEWAY. RANDOM SHIFT TO NEUTRAL ISSUE. DRIVING HOME FROM THE PURCHASING THE CAR ON THE 101 SOUTHBOUND IN THE FAST LANE GOING 65 MPH. ACCELERATION WAS SUDDENLY LOST. THE POWER TRAIN MALFUNCTIONED AND SHIFTED ITSELF INTO NEUTRAL. THE GAS PEDAL WAS UNRESPONSIVE. HAD TO PULL OVER AT WOODMAN EXIT ON INERTIA ALONE. WE HAD JUST PURCHASED THE CAR ONLY 2 HOURS PRIOR TO THIS INCIDENT AND PUT 30 MILES ON THE ODOMETER. NO WARNING LIGHTS APPEARED. MY RESEARCH ON THIS ISSUE SHOWS THAT IT IS THAT SAME ISSUE THAT HAS CAUSED THE RAV4 EV RECALL. THIS ISSUE IS EXTREMELY DANGEROUS AND IS AFFECTING MANY OTHER B-CLASS OWNERS.

THIS INCIDENT HAS HAPPENED TWICE SINCE WE GOT THE CAR ON 06/25/2015. FIRST TIME, DRIVING DOWN A STREET AT 35 MPH AND THE CAR WILL SHIFT BY ITSELF INTO NEUTRAL. THE CAR WILL NOT GO BACK TO DRIVE AND THERE IS NOT POWER TO THE DRIVE SYSTEM. THE ONLY WAY TO CORRECT IT IS TO COAST TO A STOP AND TURN OFF THE CAR AND RESTART IT TO CONTINUE DRIVING. THE SECOND TIME, ON 7/10/2015 MY WIFE WAS DRIVING ON THE FREEWAY AT 55MPH AND SAME THING HAPPENED AGAIN, BUT WAS PUT IN A MORE DANGEROUS SITUATION SINCE SHE WAS TRAVELING IN THE LEFT LANE AND THERE WAS NO CENTER MEDIAN. IT HAS BEEN AT THE DEALERSHIP EVER SINCE. THEY STATED THAT THE POWERTRAIN CONTROL UNIT NEEDS TO BE REPLACED, BUT HAVE NOT TIME ESTIMATE ON WHEN THEY WILL BE GETTING THE PART. THEY ARE NOT EVEN SURE IF THIS WILL CORRECT THE ISSUE. *TR
