2015 GMC SIERRA 1500 Complaints

UNDER BODY COATING IS PEELING ON A BRAND NEW TRUCK. ITS RUSTING BECAUSE THE STEEL IS COMPLETELY EXPOSED.

WHEN I FIRST GOT THE TRUCK THE BRAKES OPERATED PERFECTLY FINE AFTER ABOUT THREE DAYS THE BRAKES ON THE FRONT OF THE TRUCK WOULD LOCK UP WHILE I WAS DRIVING AND WOULD NOT RELEASE. AFTER TWO SETS OF CALIPERS TWO SETS OF BRAKE PADS A SET OF ROTORS A TWO WEEKS GO BY WITH THE MECHANIC TRYING TO FIGURE OUT WHAT IS WRONG WITH THIS TRUCK. THEY THEN REPLACE THE BRAKE MASTER CYLINDER, THERE WAS NO IMPROVEMENT. TURNS OUT TO BE THE BRAKE BOOSTER HAD FAILED ALONG WITH THE HYDRAULIC ABS CONTROL UNIT. THERE WERE NO WARNING LIGHTS ON WHATSOEVER THE WHOLE ENTIRE TIME THE BRAKES WERE LOCKED UP THE ABS LIGHT DIDN'T COME ON UNTIL THE BRAKE BOOSTER WAS REPLACED INDICATING THAT THE ABS CONTROL UNIT WAS ALSO BAD. NOW I AM EXPERIENCING A TICKING COMING FROM THE ENGINE. THE TICKING OCCURS AT IDLE END AS THE THROTTLE IS BEING ACTIVATED. HOWEVER THE LOCAL DEALERSHIP HAS REFUSED TO GIVE ME ANY INFORMATION AS OF WHY IT COULD BE MAKING THIS TICKING NOISE OR IS JUST UNWILLING TO SAY ANYTHING .

I PUSHED ON THE BRAKES WHEN SLOWLY PULLING INTO A PARKING SPOT AND THE BRAKES GOT SQUISHY AND BARELY STOPPED BEFORE I HIT ANOTHER PARKED CAR. THIS HAPPENED A FEW TIMES BEFORE I GOT THE VEHICLE HOME. THEN A MESSAGE POPPED UP THAT SAID "SERVICE BRAKE ASSIST SYSTEM". I TOOK THE TRUCK IN AND THEY SAID THEY WOULD NEED TO REPLACE THE VACUUM PUMP AND 2 BELTS.

THIS COMPLAINT IS REGARDING EXCESSIVE SURFACE RUST ON NOT ONLY THE FRAME OF MY TRUCK, BUT ON CRITICAL ENGINE COMPONENT CLAMPS IN THE ENGINE BAY. ANY SCREW STYLE HOSE CLAMP IN MY ENGINE BAY ARE RUSTED WORSE THAN MY OTHER 9 YEAR OLD CAR WITH 102,000 MILES ON IT. I WASH MY TRUCK, INCLUDING UNDERCARRIAGE, PERIODICALLY THROUGHOUT THE WINTER TO TRY AND KEEP THE SALT OFF. MY TRUCK IS A 2015 WITH 40,000 MILES, AND JUST RECENTLY, THE RUST HAD COMPLETELY EATEN THROUGH THE LOWER RADIATOR HOSE CLAMP CAUSING ALL THE ENGINE COOLANT TO LEAK OUT. I NOTICED THE REST OF THE CLAMPS WITHIN THE ENGINE BAY TO BE IN THE SAME CONDITION, ALONG WITH THE FRAME, AND SUSPENSION COMPONENTS. IT IS CLEARLY ONLY A MATTER OF TIME BEFORE THEY FAIL WHILE I AM DRIVING, WHICH COULD CAUSE A FAILURE OF ANY SYSTEM USING ONE OF THESE RUSTED CLAMPS, SUCH AS THE BRAKE LINES, POWER STEERING LINES, OIL LINES, OR TRANSMISSION FLUID LINES.

BRAKE ASSIST WARNING LIGHT CAME ON WITH HARD BRAKE PEDAL AT LOW SPEED BRAKING. DOES NOT HAPPEN OFTER. BROUGHT TO DEALER AND HAD TESTED WITH NO TROUBLE FOUND. DEALER SAID NO RECALLS OR SERVICE BULLETINS ON ISSUE.

BRAKES NOT WORKING. HAD TO REPLACE THE VACUUM PUMP BELT, BRAKE BOOSTER VACUUM PUMP, AND AC BELT. COST $573.86. VEHICLE ONLY HAS 40K MILES. VERY DANGEROUS, VEHICLE WOULD NOT STOP WHEN APPLYING BRAKES

AT LOW SPEEDS BREAKING BECOMES EXTREMELY DIFFICULT LEADING TO LONGER STOPPING DISTANCE.

REMOTE STARTED CAR. UPON ENTERING AND TURNING IGNITION ON A STRONG ELECTRICAL BURNING SMELL WAS NOTICED. WHITE SMOKE WAS SEEN EMITTING FROM BASE OF DRIVER SIDE REAR WINDOW BEHIND MY CHILDS CAR SEAT. MOMENTS LATER A LOUD BANG WAS HEARD AND WINDOW SHATTERED. VEHICLE WAS STATIONARY AT THE TIME AND RUNNING FOR LESS THAN 5 MINUTES.

BRAKES FADE AT LOW SPEEDS, VEHICLE CONTINUES TO TRAVEL WHILE THE BRAKES ARE APPLIED. HARD BRAKE PEDAL PRESSURE MUST BE APPLIED TO STOP.

BRAKE PEDAL OR THAT INCREASED EFFORT IS NEEDED TO DEPRESS THE BRAKE PEDAL. ALSO, IN SOME CASES A TICK OR TICKING NOISE MAY BE HEARD, WHICH MAY SOUND LIKE AN EXHAUST MANIFOLD LEAK.
