BRAKING SYSTEM FAILURE AT LOW SPEEDS.

WHEN AT SLOW SPEEDS, BRAKES GET HARD AND HAVE TO PUT A LOT OF PRESSURE TO STOP THE TRUCK.

Mileage: 20

IF THE BRAKES ARE PUMPED 2-3 TIMES THE PEDDLE WILL BECOME REALLY FIRM AND HARD TO PRESS. WHEN THIS OCCURS THE TRUCK WILL NOT STOP. YOU HAVE TO STAND ON THE BRAKE PEDAL WITH BOTH FEET TO GET THE TRUCK TO STOP. PRETTY UNNERVING FOR A 75K MIKE TRUCK STILL UNDER DRIVETRAIN WARRANTY BUT NOT COVERED. I USE THIS TRUCK FOR WORK AND HAULING MY KIDS. I DON'T LIKE HAVING MY KIDS IN THIS VEHICLE!

WHILE DETAILING MY TRUCK ON OCTOBER 30, 2017 I DISCOVERED A CRACK ON THE DASH ABOUT AN INCH AND A HALF LONG RUNNING FROM THE TOP LEFT OF THE AIRBAG COVER TOWARDS THE DEFROSTER VENT . TOOK THE VEHICLE IN FOR SERVICING ON OCTOBER 31, 2017 AND THEY STATED TO CONTACT GMC CARES THAT THEY WERE FAMILIAR WITH THIS KIND OF PROBLEM. I CALLED GMC THEY STATED THEY WERE UNAWARE OF THIS PROBLEM ON MY MAKE AND MODEL TRUCK. THEY STATED THAT I NEEDED TO CONTACT THE DEALER AND HAVE THE DEALER CONTACT GMC. THE DEALER TOLD ME TO CONTACT GMC. AFTER DOING A QUICK SEARCH ON THE INTERNET I DISCOVERED THIS HAS BEEN AN ONGOING PROBLEM THAT GMC HAS BEEN AWARE OF AND IS NOT FIXING AND APPARENTLY THIS WILL ONLY GOING TO GET WORSE AS TIME GOES BY. THE SAFETY CONCERN I HAVE IS IT SO CLOSE TO THE AIRBAG ON THE PASSENGER SIDE THAT IF THE AIRBAG DEPLOYS IN A CRASH WILL CAUSE SHARDS OF BROKEN DASH TO FLY AROUND IN THE CAB INJURING THE PASSENGERS..

CHROME WHEEL CORROSION. CRITICAL LOCATION AROUND VALVE STEM CREATING AIR LEAK IN VALVE STEM. COULD CREATE LOW ENOUGH PRESSURE TO EFFECT HANDLING IN EMERGENCY SITUATION. LUCKILY MINE WAS A SLOW LEAK, BUT THE ONLY FIX IS WHEEL REPLACEMENT AT EXTREME COST AND A LENGTHY REPLACEMENT PROCESS LEAVING THE OWNER WITH CHOICE OF UNSAFE USE, OR LOSING USE OF THE VEHICLE DURING THE PROCESS. INITIAL FIRST AID WAS TO CLEAN THE STEM HOLE OF CORROSION, USE A SEALANT AROUND THE NEW VALVE STEM, WITH NO GUARANTEE OF A SAFE FIX AND AN UPCOMING 2 WEEK TRIP TO UPPER ONTARIO CANADA IN FULLY LOADED VEHICLE.
