2014 Mercedes-Benz C250 problems and owner complaints

DRIVING ON A FOUR-LANE STREET (TWO LANES ON EACH SIDE) WITH MY TWO KIDS. THE 2014 C250 HAD A MALFUNCTION WITH THE ELECTRIC STEERING: AUTOMATICALLY JERKING THE CAR TO THE RIGHT. I LOST CONTROL OF THE CAR AND HIT THE CURB. IT FELT LIKE WE WENT AIRBORNE. I TURNED THE STEERING WHEEL TO THE LEFT TO TRY TO STABILIZE THE CAR, QUICKLY REALIZING THERE WAS TRUCK TO THE LEFT I TURNED THE STEERING WHEEL BACK TO THE RIGHT TO AVOID HITTING THE TRUCK.

I WAS DRIVING ON I-10 EASTBOUND AT APPROXIMATELY MILE MARKER 180 TO 182, WHEN I MADE A LANE CHANGE TO LET A FASTER MOVING VEHICLE PASS ME. I WENT FROM THE LEFT TO RIGHT LANE WITH THE CRUISE CONTROL SET AT 70 OR 75 MPH, (SPEED LIMIT ON I-10 IS 75 MPH). UPON ENTERING THE RIGHT LANE I SAW A TRACTOR TRAILER BRAKE LIGHTS, AND I SLAMMED ON THE BRAKE IN MY C 250, AND IT CAUSED THE CAR WHEELS TO LOCKED UP, WHICH ALSO CAUSED THE CAR TO SKID, AND SWERVE THE BACK END.

THIS PROBLEM FIRST STARTED 2 DAYS AFTER PURCHASE OF THIS BRAND NEW 2014 MERCEDES C CLASS. UPON STARTING THE VEHICLE THE EMERGENCY BRAKE INDICATOR LIGHT COMES ON AND ALARM STARTS DINGING EVEN THOUGH THE EMERGENCY BRAKE HAS NEVER BEEN APPLIED.

THE PROBLEM WAS REPORTED TO THE DEALERSHIP AND THEIR TECHNICIANS RESPONSE IS " THE C CLASS DOES THAT". AFTER TAKING THE VEHICLE BACK TO THE DEALER THE TECHNICIANS SAID…

LEASED OUR MERCEDES AND SHORTLY AFTERWARDS WE STARTED EXPERIENCING HESITATION, LAGGING AND EVEN STALLING OF THE VEHICLE AS WE TRIED TO ACCELERATE. TWICE THE VEHICLE HAS STALLED AS WE PULLED INTO TRAFFIC, NARROWLY ESCAPING POSSIBLE INJURY AND DAMAGING SEVERAL CARS. HESITATION HAS OCCURRED WITHOUT WARNING, (PRESSING ON ACCELERATOR AND THE ENGINE DOES NOT RESPOND BY EVIDENCE OF NO RPM INCREASE). AGAIN, THIS HAS OCCURED NUMEROUS TIMES. WE HAVE HAD THE VEHICLE BACK TO MERCEDES FOUR TIMES, FOR A TOTAL OF 39 DAYS!!!! AND STILL TO THIS DAY, THE VEHIC…

RANDOM ENGINE STALL INVOLVING TURBO AND INTERCOOLER: WE PURCHASED THIS 2014 C250 WITH ROUGHLY 8,000 MILES FROM NEARBY MB DEALER. WE HAVE ENJOYED THE CAR IMMENSELY, EXCEPTION THIS VERY SERIOUS "DEFECT" WITH THE ENGINE. OBSERVED ON THREE SEPARATE OCCASIONS, THIS PROBLEM IS VERY SERIOUS AND COULD LEAD TO POTENTIAL COLLISION WHILE PASSING ANOTHER VEHICLE, BECAUSE THE ENGINE "STALLS" UNDER INTENSE ACCELERATION RANDOMLY, LEAVING ONLY ONE CYLINDER WORKING. WITH THIS ONE REMAINING CYLINDER, THE CAR CAN BARELY BE OPERATED, SHAKING ETC., BUT CAN BE …

I HAD BEEN DRIVING ON THE FREEWAY, GOT OFF ONTO A SIDE ROAD AND WHEN APPROACHING A STOP LIGHT WHILE BRAKING: MY CAR COMPLETELY DIED (WHILE IN DRIVE). THE MOTOR SHUT OFF, THE ELECTRICAL DASH SYSTEM LIGHTS ALL WENT OFF AND THE HAZARD TRIANGLE SYSTEM CAME ON (WITH THE SYMBOL OF AN EXCLAMATION MARK(!) INSIDE THE TRIANGLE). AFTER ABOUT A MINUTE AND A HALF, I PUT IT IN PARK, AND IT RESTARTED. SCARY! I HAD A FULL TANK OF GAS.
