NHTSA Complaint #11066913 — 2016 GMC CANYON

TRANSMISSION HUNTS FOR GEAR WHEN TRYING TO ACCELERATE 25-40 MPH WHEN TRANSMISSION TEMP IS 120 DEGREES AND HIGHER IN SLOW AND GO DRIVING. LEADS TO DANGEROUS SITUATION BECAUSE ACCELERATOR PEDAL MUST BE 'STOMPED' ON TO GET TRANSMISSION TO DOWNSHIFT. ESPECIALLY DANGEROUS ON WET ROADS WHEN REAR OF TRUCK CAN SWERVE WHEN ACCELERATING AND IN SLOW AND GO TRAFFIC HAVING TO PUSH HARD ON ACCELERATOR TO GO WHEN MANY CARS AROUND. GM KNOWS OF THE PROBLEM AND PUBLISHES PAPER STATING EXACTLY THE SYMPTOMS AND AND TELL DEALERS NOT TO TAKE FURTHER ACTION OTHER THAN MAKING SOFTWARE UP TO DATE WHICH SOLVES NOTHING. NOT ALL GM TRUCKS AND EVEN CARS OF THIS YEAR ARE AFFECTED BUT YEARS BEFORE AND AFTER FOR DECADES HAVE THIS SAME ISSUE AS FOUND ON INTERNET FORUMS. CHANGING TO DIFFERENT TRANSMISSION FLUIDS AND EVEN CHANGING TORQUE CONVERTORS HAS BEEN DONE IN THE PAST BUT FOR 2015/2016 NO REMEDY IS OFFERED. THIS HAS BEEN GOING ON 1.5 YEARS SINCE NEW AND GETTING WORSE. BECAUSE OF LACK OF OUT OF SERVICE DAYS I DON'T THINK LEMON LAW APPLIES
