NHTSA Complaint #10786190 — 2015 CHEVROLET COLORADO

SLUGGISH ENGINE AFTER SLOWING DOWN AND THEN TRYING TO INCREASE SPEED, ENGINE JUMPS AND HESITATES FOR A FEW SECONDS THEN IF YOU STOMP ON THE GAS PEDAL IT DOWNSHIFTS AND TAKES OFF AFTER REVING TO ABOUT 5,000 RPMS. THIS USUALLY HAPPENS WHEN SLOWING DOWN TO ABOUT 20-30 MPH THEN STARTING TO INCREASE SPEED. IT IS TRULY EMBARRASSING OWNING THIS $37,0000 TRUCK. DEALERSHIP AND GM CUSTOMER SERVICE STATED THAT THE ENGINE NEEDS TO LEARN HOW I DRIVE AND ADAPT. REALLY? THE ENGINE IS REMAINING IN TOO HIGH OF A GEAR AND NOT DOWNSHIFTING AND SUPPLYING THE ENGINE POWER THAT IS REQUIRED IN TRAFFIC. THIS PROBLEM HAS EXISTED SINCE I PURCHASED THE VEHICLE 11/1/14, I'VE IGNORED THE PROBLEM HOPING IT WOULD GO AWAY BUT HERE I AM.
