NHTSA Complaint #10383333 — 2011 GMC SIERRA 1500

OEM TIRES HAVE EXTREMELY POOR WET PAVEMENT TRACTION. FIRST INCIDENT OCCURRED LESS THAN 30 DAYS AFTER PURCHASING THE VEHICLE. IT HAD RAINED HEAVILY FOR AN EXTENDED TIME THAT DAY AND CONTINUING MODERATELY INTO THE EVENING. APPROACHING THE INTERSECTION WHERE I INTENDED TO MAKE A TURN ONTO A SIDE STREET, I BEGAN SLOWING TO WHAT I CONSIDERED A SAFE AND PRUDENT SPEED GIVEN THE ROAD CONDITIONS. UPON APPLYING THE BRAKES THE VEHICLE COULD NOT BE STOPPED RESULTING IN SLIDING COMPLETELY STRAIGHT THROUGH THE INTERSECTION, LUCKILY ON A GREEN SIGNAL LIGHT, AND WITH NO OTHER TRAFFIC IN MY PATH. REALIZING I WAS NOT SLOWING SUFFICIENTLY TO NEGOTIATE THE TURN, I DID NOT ATTEMPT TO TURN THE STEERING WHEEL AND CONTINUED DOWN THE SAME STREET TO A SAFE AREA TO TURN AROUND AND RETURN TO THE STREET I INTENDED TO TURN ONTO. SECOND INCIDENT, AGAIN ON WET PAVEMENT, WAS AFTER MAKING A COMPLETE STOP AT A TRAFFIC LIGHT CONTROLLED INTERSECTION. WHEN THE SIGNAL LIGHT CHANGED TO GREEN, I STARTED NEGOTIATING A LEFT TURN. APPROXIMATELY HALF WAY THROUGH THE INTERSECTION, AT A SPEED OF LESS THAN 10 MPH, REAR TIRES LOST TRACTION AND THE REAR OF THE VEHICLE TRIED TO SWAP ENDS. NEEDLESS TO SAY, MY WIFE YELLED AT ME TO STOP DOING WHATEVER IT WAS THAT I DID TO CAUSE SUCH ACTION, TO WHICH I REPLIED. I DID NOT DO ANYTHING OTHER THAN START MOVING FORWARD AT A SLOW PACE AND WAS JUST AS SURPRISED AS SHE WAS BY THE BEHAVIOR OF THE VEHICLE. *TR
