There are 4 owner-reported brakes complaints for the 2015 Mercedes-Benz CLA-Classin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Had an update on the software to control collision prevention on the car, and soon afterward it began to deploy at certain spots without any other car in front for at least 50 feet. Took it back to the M-B Seattle dealer and after 4 weeks of investigation, I was told that the matter is exterior to the car and that the car performs as intended. T still drive the car and it still gives me warnings of impending to engage the collision detection braking system. I don't feel very comfortable driving it in the city.
MY CONCERN IS BRAKE AND ROTORS. I REPLACED BRAKES A FEW MONTHS AFTER PURCHASING MY VEHICLE IN 2020. MY DEALERSHIP WAS NOT HELPFUL ABOUT EXPERIENCE. I ASKED WHY BRAKES WERE NOT INSPECTED B4 PURCHASE AND AFTER SEVERAL CALLS REPAIRS WERE DONE. IT'S BEEN 1 YEAR AND VEHICLE HAS NOT BEEN DRIVEN MUCH DUE TO COVID. NOW HAVING SAME PROBLEMS WITH SHAKING AGAIN.. I FEEL BRAKES ARE A ON GOING PROBLEM WITH THIS MODEL AND I NEED ANSWERS. I HAVE READ MANY COMPLAINTS ON LINE ABOUT THIS PROBLEM WITH BRAKES ROTORS ON CLA250 MERCEDES BENZ .PLEASE HELP
THE BRAKE PEDAL AND THE GAS PEDAL ARE TOO CLOSE TOGETHER. I AM CONSTANTLY FEELING THE SLIGHT TOUCH OF THE BRAKE PEDAL WHEN STEPPING ON THE GAS. I HAVE HAD MULTIPLE CARS AND SUV'S IN THE PAST AND I CANNOT EVERY RECALL TOUCHING THE BRAKE WHEN GASSING. I AM VERY CONSCIOUS OF THE PROXIMITY OF THE 2 PEDALS AND TRY TO NOT TOUCH THE BRAKE. IT STILL HAPPENS FROM TIME TO TIME.
THERE WAS NO INCIDENT WITH THE CAR. I PURCHASED THE CAR NEW AND WHEN DRIVING IT I DETECTED A POTENTIAL SAFETY HAZARD WITH THE POSITIONS OF THE BRAKE AND GAS PEDALS AND THEIR RELATIONSHIP ARE TOO CLOSE TO EACH OTHER. FOR EXAMPLE IF YOUR ARE WEARING MEN'S TENNIS SHOES THEIR IS A HAZARD OF TOUCHING BOTH THE BRAKE AND GAS WHEN YOU WANT TO APPLY THE BRAKE YOU ALSO APPLY THE GAS. SIMPLY BECAUSE THE SHOES ARE TOO WIDE. THE DIMENSIONS ARE: THE BRAKE PEDAL IS 5" X 3" AND THE GAS PEDAL IS 2" WIDE AND 6" LONG. THE SEPARATION BETWEEN THE TWO PEDALS IS 2 INCHES. THE GAS PEDAL IS 1 INCH FROM THE CENTER WALL ON THE RIGHT AND THE BRAKE PEDAL IS 10 INCHES FROM THE LEFT WALL. I DON'T IF THESE TOLERANCES ARE ACCEPTABLE ONLY DOT WOULD KNOW.
