PASSENGER DOOR HANDLE SOMEHOW BECAME DISENGAGED AND JUST FULLS OUT LOOSELY. HAVE TO GET IN AND OPEN FROM INSIDE. IT APPEARS TO HAVE A PLASTIC HOOK ON THE HANDEL THAT MUST HAVE DISENGAGED FROM SOMETHING INSIDE THE DOOR. DOOR HARDLY GETS USED. IS THIS ACOVERED PROBLEM???

I HAVE BEEN SMELLING A STRONG ODOR OF GAS COMING THRU MY AIR VENTS WHILE MY VEHICLE IS RUNNING, PARTICULARLY WHILE I AM IDLING AND JUST AFTER ACCELERATION. MY MECHANIC STATED HE HAS REPAIRED SEVERAL OF THESE ISSUES ON OTHER GMC'S. THE PROBLEM IS THE TOP OF THE FUEL TANK IS RUSTED WHERE THE FUEL PUMP IS LOCATED AND GAS SPRAYS UPWARDS ONTO THE BOTTOM SIDE OF THE BED AND IS VERY COSTLY AND DIFFICULT TO REPAIR. I'M SURE GM IS AWARE OF THE PROBLEM, HOWEVER, THEY HAVE CHOSEN TO IGNORE THE ISSUE. THIS IS MOST DEFINITELY A SAFETY ISSUE!

WHEN VEHICLE STARTS MOVING FOREWARD FROM A DEAD STOP AND WHEN AUTOMATIC TRANSMISSION SHIFTS FROM 1ST GEAR TO SECOND GEAR THERE IS A HARD CLUNK.THIS HAS BEEN HAPPENING SINCE 15000 MILES.WHEN I BRING TO DEALER ,THEY WANT TO KEEP TRUCK ,LEAVING ME WITHOUT VEHICLE.WIFE AND I WERE ON MAJOR HWY AND HAD TO SHUT VEHICLE DOWN IN TRAFFIC TO STOP THE CLUNK.VERY DANGEROUS SITUATION.

WHILE DRIVING TO WORK ONE MORNING AN ERROR MESSAGE FLASHED ENGINE REDUCED POWER, STABILITY CONTROL LOSS. TRUCK STRUGGLED TO ACCELERATE. HAS HAPPENED SEVERAL TIMES SINCE NOVEMBER 2015 ON CITY STREETS OR HIGHWAYS CAN HAPPEN AT ANY TIME. I HAD TO REPLACE ENTIRE SYSTEM FROM THROTTLE BODY TO THE PEDAL ASSEMBLY HAVE FOUND OUT THAT THIS IS COMMON PROBLEM THAT GM KNOWS ABOUT ALONG WITH THE CRACKS IN THE DASH AROUND AIR BAG ON PASSENGER SIDE AND THE INSTRUMENT CLUSTER AND REFUSES TO RECALL AND FIX CRACKS IN AIR BAG HOUSING COULD POSE A SAFETY HAZARD ALONG WITH LOSS OF ENGINE POWER FROM FAULTY WIRING.

CRACKED DASHBOARD - THE DASHBOARD ON MY 2012 GMC SIERRA 1500 SERIES TRUCK HAS CRACKED ON BOTH THE DRIVER AND PASSENGER SIDE. NOW, DUE TO THE SEVERE COLD, THE CRACK ON THE DRIVER'S SIDE IS EXPANDING DUE TO THE EXPANSION AND CONTRACTION OF THE PLASTIC THRU INTERIOR HEATING AND RAPID COOLING OF THE VEHICLE. THESE CRACKS OCCURRED DURING NORMAL DRIVING CONDITIONS ON STATE HIGHWAYS AND INTERSTATES.

ON COLD MORNING STARTS, FRONT BRAKE PADS WILL ENGAGE ROTOR, AND RELEASE VERY SLOWLY. THEN ON A TURN, FRONT PADS WILL ENGAGE, LOCK FOR A SHORT TIME, AND THEN SLOWLY RELEASE. SEEMS LIKE ENGINE HAS TO WARM UP BEFORE BRAKES ACT NORMAL. AFTER COLD MORNING STARTUP, BEFORE MOVING VEHICLE, IF BRAKE PEDAL IS PUMPED REPEATEDLY FOR 30 SECONDS, BRAKES WILL TRY TO ACT NORMAL, WHEN VEHICLE IS MOVED. I AM ON MY 2ND SET OF FRONT PADS AND ROTORS. 1ST SET WERE SEVERALLY WORN. TECH SAID IT LOOKS LIKE YOUR CALIPERS WERE STICKING.
