NHTSA Complaint #10822934 — 2015 GMC CANYON

VEHICLE UPSHIFTS TOO EARLY AT LOW SPEEDS REQUIRING ADDITIONAL ACCELERATOR INPUT THEN DOWNSHIFTS 2 GEARS TO COMPENSATE. THIS HAPPENS REGULARLY WHEN GOING AROUND 15-20 MILES AN HOUR UPHILL OR WHILE MAKING RIGHT TURNS WHILE VEHICLE IS IN MOTION. WHEN THE VEHICLE IS SEARCHING FOR THE CORRECT GEAR THE ACCELERATOR PEDAL IS NUMB FOR AT LEAST 2 SECONDS REQUIRING AT LEAST 90 PERCENT THROTTLE THEN IT FINALLY PICKS A LOW GEAR AND VIOLENTLY THROWS THE DRIVER AND PASSENGERS BACK AND ROARS TO LIFE. THE 2 OR MORE SECONDS OF HESITATION COULD BE VERY DANGEROUS IN AN EMERGENCY SITUATION WHEN QUICK ACCELERATION IS NEEDED. MY CONCERNS WERE VOICED TO BOWSER BUICK GMC ON 11/20/2015 DURING MY FIRST OIL CHANGE AND THEY PROVIDED ME WITH SERVICE BULLETIN #PIP5342 WHICH STATES "SHUDDER OR CHUGGLE WHEN ACCELERATING AT LOW SPEEDS OF 12-15 MPH IN SECOND GEAR IS NORMAL OPERATION OF THE AUTOMATIC TRANSMISSION AND THE TORQUE CONVERTER CLUTCH. NO REPAIR ATTEMPTS SHOULD BE ATTEMPTED TO ADDRESS THIS CONCERN" THEY REFUSED TO MAKE ANY REPAIRS AND SAID THAT I WAS ADDED TO A LIST OF OTHERS WITH SIMILAR COMPLAINTS.
