NHTSA Complaint #10550890 — 2014 MERCEDES-BENZ CLA250

ON SUNDAY, OCTOBER 27, AND TUESDAY, OCTOBER 29, 2013, MY VEHICLE LISTED ABOVE HAD WARNING LIGHTS COME ON THAT STATED, "PRE SAFE, FUNCTIONS LIMITED, INOPERATIVE." IN ADDITION TO THE WORDS, THE ESP AND ABS LIGHTS ILLUMINATED. I TOOK THE VEHICLE TO PENSKE MBZ IN WEST COVINA, CA, ON WEDNESDAY, OCTOBER 30. THEY REPAIRED THE VEHICLE BY DOING A SOFTWARE UPDATE. ON SATURDAY, NOVEMBER 2, 2013, THE CODES RETURNED AND I TOOK THE VEHICLE BACK TO WHERE I BOUGHT IT, ENCINO, CA, MBZ. I WAS TOLD THEY COULD NOT REPLICATE THE CODES AND THEY FOUND NO PROBLEM. THIS IS UNACCEPTABLE! THE VEHICLE IS STILL AT ENCINO MBZ AS THEY ARE TRYING TO REPLICATE THE PROBLEM. WHEN THIS MALFUNCTION OCCURS, THE VEHICLE LOSES POWER AND HAS VERY LIMITED ACCELERATION. IT HAS OCCURRED TWICE ON CITY STREETS AND TWICE ON THE FREEWAY, BOTH IN ECO AND SPORT MODE. ON THE CITY STREETS I AM ABLE TO JUST PULL TO THE CURB. ON THE FREEWAY, IT BECOMES A POSSIBLE LIFE THREATENING EMERGENCY. THERE IS ONLY VERY GRADUAL ACCELERATION, AND AT 65MPH, LIMITED ACCELERATION IS VERY DANGEROUS. THESE FOUR OCCURRENCES HAVE TAKEN PLACE IN LESS THAN A 10 DAY PERIOD AND NO LONG TERM REPAIR HAS YET BEEN ACCOMPLISHED! *TR
