NHTSA Complaint #11013853 — 2016 RAM 1500

UNPREDICTABLE AND SOMETIME VIOLENT DOWNSHIFTING CAUSING MOMENTARY LOSS OF CONTROL OF THE VEHICLE WHEN DRIVING IN WET, SLIPPERY CONDITIONS. THIS HAS OCCURRED ON SEVERAL OCCASIONS WHILE DRIVING THROUGH RAIN STORMS. THE VEHICLE STARTED TO EXHIBIT ERRATIC SHIFTING BEHAVIOR AT ~5,000 MILES AND HAS GOTTEN PROGRESSIVELY WORSE TO A POINT THAT THE TRANSMISSION UNPREDICTABLE SHIFTING OCCURS IN ALL CONDITIONS. THE IMPACT OF THE SHIFTS IS SEVERE ENOUGH THAT IT IS BEING TRANSMITTED THROUGH THE DRIVER'S SEAT CREATING EXTREME DISCOMFORT AND PAIN TO THE LOWER BACK. A 'SERVICE SHIFTER' MESSAGE IS ALSO BEING DISPLAYED. THE VEHICLE WAS TAKEN IN TO THE DEALERSHIP. THE DEALERSHIP STATED THAT THEY DON'T KNOW WHY THE 'SERVICE SHIFTER' MESSAGE IS COMING ON BECAUSE NO TROUBLE CODES ARE SHOWING; THEY RE-FLASHED THE CPU TO SEE IF WOULD CORRECT THE ERRATIC AND UNPREDICTABLE SHIFTING, IT IS NOT WORKING, IN FACT IT HAS GOTTEN WORSE. THE DEALERSHIP ALSO STATED THAT THE VEHICLE MAY HAVE A DEFECTIVE DRIVESHAFT WHICH MAY BE CONTRIBUTING TO THE HARSH SHIFTING, THEY HAVE ONE ORDER.
