NHTSA Complaint #10863978 — 2013 DODGE CHALLENGER

ABOUT 25% OF THE TIME, WHILE DRIVING ON A CITY STREET AT 40 MPH AND GRADUALLY PRESSING THE ACCELERATOR TO BEGIN A CLIMB UP A SLIGHT HILL, THE ENGINE RPM AND VEHICLE SPEED WILL NOT INCREASE, AND THE VEHICLE WILL CONTINUE TO RUN AT 40 MPH WITH ACCELERATOR POSITION INCREASING FROM 10% TO 80%. DURING THIS THROTTLE RESPONSE FAILURE, THE AUTO STICK SHIFT WAS USED TO DOWNSHIFT FROM 4TH TO 3RD GEAR, THE EVIC DISPLAY CHANGED TO 3RD GEAR BUT AND TRANSMISSION REMAINED IN 4TH. AFTER 8 SECONDS OF THROTTLE DELAY (TIMING MAY VARY), THE VEHICLE WILL DOWN SHIFT AND ACCELERATE. THIS UNPREDICTABLE THROTTLE RESPONSE HAS A POTENTIAL OF CAUSING AN ACCIDENT IF THIS THROTTLE RESPONSE FAILURE OCCURS DURING A SITUATION OF PASSING OR AVOIDING ANOTHER VEHICLE. I HAVE BROUGHT THE VEHICLE BACK TO THE DODGE DEALER ON NOV 2015 AND APR 2016, AND THEY TOOK IT FOR A TEST DRIVE AND CONCLUDED THAT THE VEHICLE IS FINE. THEY COULD NOT REPEAT THE FAILURE AND TOLD ME EVERYTHING IS NORMAL. DODGE WILL NOT, OR CANNOT FIX THE ROOT CAUSE OF THIS THROTTLE RESPONSE FAILURE.
