Open the full vehicle complaint log (all categories)THE FACTORY INSTALLED RUNNING BOARDS ARE UNSAFE. THE TREADS NEED TO BE LARGER, MORE AGGRESSIVE AND ROTATED 90^. AS THEY ARE THEY ARE SIMPLY SKID PADS WHEN WET OR FROZEN. YOU SIMPLY NEED TO TRY AND ENTER OR EXIT THE VEHICLE AND SEE HOW EASILY YOUR FOOT SIDES OFF CAUSING THE PERSON THE FALL. I HAVE TAKEN SEVERAL SLIPS/FALLS. TODAY I HIT THE BACK OF MY HEAD ON THE DOOR JAM. JUST ROTATING THE TREAD NINETY DEGREES WOULD HELP.
TL* THE CONTACT OWNS A 2014 GMC SIERRA. THE CONTACT STATED THAT THE HEADLIGHTS WERE DIM AND PROVIDED POOR VISIBILITY. THE FAILURE WAS WORSE IN RAINY CONDITIONS.

WHILE ON VACATION I BOUGHT A 2014 SIERRA DENALI THAT WAS PREVIOUSLY DRIVEN BY A GM EXECUTIVE AND BOUGHT BY THE DEALERSHIP IN W.VA. AFTER COMING HOME I LOOKED UNDERNEATH AND SAW THAT THE FRAME AND DRIVESHAFT WERE COVERED IN RUST. HAVE READ OTHER COMPLAINTS ON THE INTERNET ABOUT THIS SAME PROBLEM WITH THIS YEAR AND MODEL TRUCK. *TR
TL* THE CONTACT OWNS A 2014 GMC SIERRA. THE CONTACT STATED THAT THE VEHICLE WAS DESIGNED WITH LARGE HOLES IN THE GRILL. WHILE DRIVING VARIOUS SPEEDS, WEEDS WOULD ENTER THE GRILL AND ACCUMULATE NEAR THE RADIATOR. AS A RESULT, THE VEHICLE OVERHEATED. THE DEALER STATED THAT THE VEHICLE WAS DESIGNED IN THAT FASHION. NO REPAIRS WERE MADE AND THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 10. UPDATED 8/22/14*CN
WHEN WE TOOK OUR NEW TRUCK FOR A TEST DRIVE WE NOTICED A VIBRATION. THE DEALERSHIP SUPPOSEDLY CHECKED IT OUT AND TOOK CARE OF IT. WHEN TOOK DELIVERY OF THE TRUCK AND DROVE IT HOME THE VIBRATION WAS BETTER AT A SLOWER SPEED BUT INCREASED AS THE SPEED INCREASED. WE RETURNED THE TRUCK TO THE DEALERSHIP AND THEY CHECKED IT OUT AND SAID THAT THEY BALANCED THE TIRES AND ROTATED THE DRIVESHAFT 180 DEGREES. IT SEEM TO BE A LITTLE BETTER. BECAUSE WE TAKE THIS TRUCK TO FLORIDA FOR THE WINTER AND IT IS LOADED MY HUSBAND DECIDED THAT HE WOULD PUT SOME WEIGHT IN THE BACK OF IT TO SEE HOW IT WOULD AFFECT IT. THE VIBRATION WAS BETTER AT A SLOWER SPEED AND WORSE AT A HIGH SPEED ON THE HIGHWAY. THE TRUCK HAS NOW BEEN BACK AT THE DEALERSHIP FOR A WEEK AND WE HAVE NOT HEARD ANYTHING IN REGARDS TO IT. THEY ARE SUPPOSED TO BE DOING AN ELECTRONIC VIBRATION ANALYSIS ON IT. MY HUSBAND HAS RESEARCHED THIS PROBLEM ON THE INTERNET AND THERE SEEMS TO BE A LOT OF COMPLAINTS ABOUT THIS PROBLEM. HOPEFULLY PEOPLE ARE REGISTERING THEM ON YOUR WEBSITE. *TR
