2015 MERCEDES-BENZ B-CLASS ELECTRIC Complaints

MERCEDES DEALER NOTES : 07/19/2022 CLIENT STATES STEERING IS STIFF. STARTED ABOUT 1 TO 2 MONTHS AGO AND WOULD SHOW UP ONCE AND AWHILE. WHEN IT WOULD ACT UP WOULD NOT DRIVE IT AND IT WOULD LOCK THE STEERING . THIS HAPPENED MULTIPLE TIMES, WITH ACCIDENT HAZARD. WE DID THE BELOW WORK. ELECTRIC POWER STEERING RACK FAULTY REPLACE COMPLETE ELECTRIC POWER STEERING RACK. WHICH COST US OVER $3000. NOW WE HAVE SIMILIAR PROBLEM STEERING IS TIGHT AGAIN, MAKING FLAPPING NOISE, DEALER RECOMMENDED REPLACEMENT OF POWER STEERING RACK, GEAR BOX 07/02/24 , MERCEDES HAS RECALL ON MANY MODELS DURING YEAR 2015-2018 FOR electric power steering systems, Mercedes says the cars use electric power steering systems that May have soldered contacts that weren't soldered correctly inside the control units. The bad contacts can cause a sudden loss of power steering while driving, causing serious problems if driving around a curve or at slow speeds.

The electric motor was leaking coolant and needs to be replaced. I have read countless accounts that this is a known issue with this car.

Occasionally the car will lurch forward when coming to a stop. As you come to a stop it tries to propel the car forward as you are breaking and coming to a stop. Happens rarely but when it does it's a big safety concern.

Failure of seals and or bearings in the electric motor causing coolant to leak into the electric motor, creating an internal electrical fault, seizing electric motor.

Vehicle stopped suddenly and would not restart. Needs a new $17k drive unit and is out of warranty. Drive unit failed due to faulty design where coolant contaminated the electric motor. Vehicle only has 40k miles. The drive unit was built by Tesla for Mercedes. Tesla also built the same unit for Toyota for the electric Rav4. Toyota recalled their units free of charge for customers. Mercedes is aware of this issue and refuses to extend the warranty or recall the roughly 4000 B250E cars that they sold in the USA from 2014-2017.

The main electric drive motor will start leaking coolant which then damages the motor and even electronics. Well known issue and makes the vehicle unsafe and isn't a matter of "if" but "when" the seals will go bad and this is on our car that has less than 40k miles on the odometer.

THE CAR STARTED TO MAKE A SOFT TICKING SOUND. I BOUGHT THE CAR AT 11121 MILE ON JULY 2,2018 LAST WEEK I HAD THE MERCEDES BENZ DEALER PICK. THE PROBLEM WAS THE ENGINE NEEDS TO BE REPLACED. MILEAGE ON CAR NOW IS 28452. ASKING 17,000 DOLLARS FOR REPAIR. I HAVE THE PREMIUM SAFE DRIVE EXTENDED WARRANTY THEY ARE WILL TO PAY ONLY 10,000 DOLLARS. *TR

THIS MB MODEL HAS AN ELECTRIC MOTOR THAT FAILS AT AROUND 35000 TO 40000 MILES, AND MAKES THE VEHICLE TO STOP SUDDENLY CAUSING SERIOUS RISKS TO THE DRIVER IF THIS HAPPENS IN ANY MAIN HIGHWAY. TWO WEEKS AGO MY WIFE WAS DRIVING NORTHBOUND AT THE FAST LANE OF THE PALMETTO EXPRESSWAY , IN MIAMI FL, WHEN THE CAR STOPPED GIVING NO TIME TO AVOID COMING TRAFFIC. FORTUNATELY ONE FDOT RANGER WAS DRIVING SAME WAY AND PROTECT MY WIFE TURNING ON ITS EMERGENCY LIGHTS WHILE THEY WAIT FOR A TOW TRUCK TO ARRIVE. THIS MODEL OF MB IS ASSEMBLED WITH A TESLA MOTOR THAT HAS BEEN PROVEN TO FAIL, BUT TESLA HAS TAKEN FAST ACTION TO AVOID INCONVENIENCES TO ITS CUSTOMERS. MB HAS DOING NOTHING TO ADVICE ITS CUSTOMERS ON THIS CRITICAL ISSUE, PUTTING ON RISK ON A DAILY BASIS ALL DRIVERS THAT RIDE TIS MB MODEL. I FIGURE IF OTHERS ARE FACING SIMILAR ISSUES, IT WOULD BE GOOD TO GET A RECALL SET UP IF MB DOES NOT STEP UP TO THE PLATE. IT TOOK FOUR YEARS FOR THESE ISSUES TO SHOW UP NEAR THE END OF MY WARRANTY, AND SINCE THE CARS REMAIN ESSENTIALLY THE SAME THROUGH THE 2017 MODELS, WE MAY EXPECT TO SEE OTHERS MODEL YEARS SHOW THE SAME ISSUES AS THE END OF THEIR WARRANTIES COME UP. I HOPE NOT, FOR EVERYONE ELSE BUT BEST BE PREPARED. MY VEHICLE CAN BEEN INSPECTED AT THE MERCEDES BENZ OF MIAMI DEALER WHERE REPAIR ARE UNDERWAY.

CAR STALLED WHILE GOING ON EXPRESSWAY AT 30 MPH. COMPLETE LOSS OF POWER. HAD TO PULL OVER AND POWER OFF THE CAR. RESTART OF THE CAR AFTER A WHILE AND EVERYTHING WAS BACK TO NORMAL.

CAR WAS STOPPED AND THE ENGINE TURNED ITSELF OFF. RESTARTED MANUALLY. TOOK THE CAR TO THE DEALER FOR REPROGRAMMING. DID THE SAME THING AGAIN.
