NHTSA Complaint #11100193 — 2017 ACURA MDX

WE HAVE EXPERIENCED MANY ISSUES WITH OUR 2017 MDX SH-AWD. ON A COLD START WHEN SHIFTING FROM FIRST TO SECOND GEAR THERE IS A SUDDEN LURCH HARD SHIFT. ONCE WARM THIS IS STILL PRESENT BUT NOT AS PRONOUNCED. THE TRANSMISSION SEEMS TO SLIP THROUGH GEARS AND HAVE SUDDEN DOWNSHIFTS THAT DECELERATE THE CAR OR THE VEHICLE WILL LURCH FORWARD WITHOUT HAVING YOUR FOOT ON THE GAS AS IT SHIFTS ITSELF INTO A DIFFERENT GEAR. WHEN TRYING TO 'PUNCH IT' AND ACCELERATE QUICKLY IT WILL OFTEN HESITATE TO GO INTO THE CORRECT GEAR THEN SUDDENLY REV HIGH AS IT SPEEDS UP. HUNTING UP AND DOWN THROUGH GEARS WHILE STAYING AT A CONSTANT SPEED. THE NAVIGATION SYSTEM IS EXTREMELY SLOW TO COME UP AND RESPOND TO INPUTS WHEN THE CAR IS STARTED. ACURA HAS CLAIMED THIS IS DUE TO CELL PHONE BLUETOOTH INTERFERENCE. COLLISION MITIGATION SYSTEM HAS ENGAGED TWICE. THE FIRST TIME BY HUSBAND WAS IN A PARKINGLOT DRIVING THROUGH A ROW LOOKING FOR A SPOT TO PARK. THE CAR SLAMMED ON THE BREAKS WITH NO CARS IN HIS PATH AND NEARLY CAUSED THE CAR BEHIND HIM TO REAR END HIM. THE SECOND TIME I WAS APPROACHING A STOP LIGHT TO TURN RIGHT, THERE WAS A VEHICHLE IN FRONT OF ME BUT THE DISTANCE I WAS STOPING FROM THE REAR OF THAT VEHICHLE WAS NOT AN ABNORMAL OR ALARMING DISTANCE. THE BRAKES LOCKED UP WITH LIGHTS FLASHING ON THE DASH AND AN AWFUL GRINDING NOISE COMING FROM BENEATH THE CAR. ON ONE OCCASION FROM A PARKED POSITION IT WOULD NOT ALLOW US TO ENGAGE IT IN DRIVE. IT FLASHED "SHIFT TO PARK" ON THE DASH. IT TOOK THREE ATTEMPTS TO GET IT TO GO IN TO DRIVE. THE REAR HATCH HYDROLICS HAD TO BE REPLACED WITHIN THE FIRST 6 MONTHS AS THE POWER LIFTGATE STOPPED WORKING. ONE OF THE TWO KEY FOBS ALSO WENT OUT ON US IN THE FIRST 6 MONTHS, REPLACING THE BATTERY DID NOTHING AND THE WHOLE FOB NEEDED TO BE REPLACED.
