NHTSA Complaint #10910678 — 2016 TOYOTA TACOMA

NOTICED MY TACOMA BEING SLOW TO DOWN SHIFT TO A LOWER GEAR WHEN TRYING TO ACCELERATE OR IT WOULD UP SHIFT TO A HIGHER GEAR WHILE ACCELERATING/MERGING RESULTING IN AN UNEXPECTED CHANGE IN ACCELERATION. ALSO IF RIDING BETWEEN 20-40 MPH THE VEHICLE RIDES AT A VERY LOW RPM (~1100) AND SHIMMIES THE VEHICLE LIKE IT WILL STALL. VEHICLE WILL ALSO "NOTICEABLY" DOWN SHIFT WHILE THE FOOT IS OFF THE ACCELERATOR RESULTING IN AN UNEXPECTED CHANGE IN DECELERATION. THE PROBLEM SEEMS TO BE GETTING WORSE AND NOW THE SHIFTING IS STARTING TO JOLT THE VEHICLE. WHILE DRIVING AT CONSTANT SPEEDS THE VEHICLE WILL RANDOMLY SURGE HIGH IN RPMS THEN COME RIGHT BACK DOWN. THE VEHICLE IS PRESENTING UNSAFE CONDITIONS. TOOK THE VEHICLE TO THE DEALER MULTIPLE TIMES. 1ST TIME THEY TOPPED OFF THE TRANSMISSION FLUID AS IT WAS LOW FROM THE FACTORY. 2ND TIME THEY ARE AWARE OF THE ISSUE AND OTHERS WERE HAVING IT AS WELL AND THE TRANSMISSION ECU WAS RE-FLASHED. THIS STILL DID NOT RESOLVE THE PROBLEM. BROUGHT THE VEHICLE BACK A 3RD TIME AND THEY DIDN'T SEE A PROBLEM WITH THE VEHICLE. BROUGHT IT BACK A 4TH TIME TO BE SEEN BY A FIELD SPECIALIST AND THE ISSUE COULD BE DUPLICATED BUT THERE IS NO FIX AT THIS TIME BECAUSE THE VEHICLE IS OPERATING AS DESIGNED. VEHICLE CURRENTLY HAS LESS THAN 2500 MILES ON IT. NOT SURE WHY YOU WOULD DESIGN A VEHICLE TO DO THIS.
