2015 GMC SIERRA 2500 Complaints

TL* THE CONTACT OWNS A 2015 GMC SIERRA 2500. WHILE DRIVING VARIOUS SPEEDS, THE PROJECTOR HEADLIGHTS FAILED TO ADEQUATELY ILLUMINATE THE ROAD. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TCM AND BULBS WERE CHANGED PER TSB NUMBER: PIT5374 (EXTERIOR LIGHTING). THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

I LIVE IN THE MOUNTAINS OF TEHACHAPI, CANNOT SEE A THING WHEN DRIVING THE MOUNTAIN ROADS. MAYBE 40-50 FEET IN FRONT OF THE TRUCK NOTHING TO THE SIDE. MAKING A TURN IS LIKE ALMOST DRIVING WITHOUT LIGHTS.

DRIVERS SIDE, IN-MIRROR (WITH EXTENDABLE, MANUAL, TRAILER MIRROR) TURN SIGNAL TOO BRIGHT OR SHOULD BE SHIELDED FROM DRIVERS EYES. BLINDINGLY BRIGHT FOR MAKING LEFT-HAND TURNS. PROBLEM WORSENS AS AMBIENT LIGHT IS REDUCED.

THE HEADLIGHTS ARE NOT BRIGHT ENOUGH TO LIGHT THE ROADWAY SUFFICIENTLY AT NIGHT WHILE DRIVING, ESPECIALLY ON DARK RURAL ROADS AND DURING HAZARDOUS WEATHER SITUATIONS SUCH AS RAIN OR FOG. THE DIM LIGHT DOES NOT ALLOW THE DRIVER TO EFFECTIVELY SEE ROAD HAZARDS, PEDESTRIANS, BICYCLISTS, ANIMALS OR OTHER OBSTACLES THAT MAY APPEAR AND THUS IS A SAFETY HAZARD.

TRANSMISSION CONTROL MODULE FAILURE; THE TRUCK AT 45 MPH DEVELOPED A COMPLETE LOSS OF ALL GAUGES(TACH, SPEED, FUEL, TEMP) AND THEN 10-15 SECONDS LATER TWO LOUD NOISES FOLLOWED BY THE VEHICLE COMING TO A RAPID DECELERATION. THIS RESULTED IN THE WHEELS LOCKING UP AND SLIDING SIDEWISE. THE TRUCK ROLLED UP ON TO ITS LEFT TWO WHEELS AND THEN SLAMMED DOWN. IF THIS OCCURRED AT 75MPH ON THE HIGHWAY, THE TRUCK WOULD HAVE ROLLED. THE TRUCK HAS BEEN AT A GMC DEALERSHIP SINCE THEN. GMC HAS NO DATE OF IF OR WHEN THIS TRUCK CAN BE REPAIRED. THE "TCM" IS DEFECTIVE. IT WAS ON A CITY STREET, 45 MPH ZONE GOING STRAIGHT DOWN A GENTLE GRADE.

THE HEADLIGHTS ON THE GMC 2500 HD ARE NOT BRIGHT ENOUGH. THE LIGHTS ARE NOT ABLE LIGHT ROADS WITHOUT STREET LIGHTS, MAKES IT VERY DANGEROUS. FUEL FILTER HAS BEEN REPLACED TWICE AND MY TRUCK ONLY HAS 12,000 MILES ON IT. WHEN I ASKED WITH THE LIFE OF A FUEL FILTER SHOULD BE I WAS TOLD BY THE GMC DEALERSHIP AT LEAST 15,000 MILES. IT IS POSSIBLE THERE IS A MALFUNCTION WITHIN THE SENOR FOR THE FUEL FILTER.

I BOUGHT A NEW 2015 GMC DOUBLE CAB 2500 HD Z71 4X4 PICK UP TRUCK IN MAY 2015 IT HAS FACTORY EQUIPPED LT 265X70X17 BRIDGESTONE DURAVIS 7 PLY TIRES. I TOOK IT ON A UNLOADED 9000 MILE ROAD TRIP AFTER ABOUT 7000 MILES I NOTICED THE TRUCK WAS NOT HANDLING LIKE IT SHOULD IT WANTED TO GO STRAIGHT THRU CURVES IT WONDERED AND PULLED LEFT OR RIGHT. I TOOK IT TO THE GMC DEALER IN SPOKANE WASHINGTON THE FOUND THAT THE ALIGNMENT TOW-IN AND RIGHT SIDE CASTER WAS OFF. THIS IS NOT MY FIRST GM TRUCK THE LAST ONE I DROVE 93000 MILES AND NEVER NEEDED AN ALIGNMENT. WHILE DRIVING TO BEND OREGON THE PROBLEM REOCCURRED. I TOOK IT TO THE CHEVROLET GM DEALER IN BEND ALIGNMENT CHECK WAS OK THEY SAID IT MAY BE TIRE PRESSURE RELATED I AM USING THE RECOMMENDED COLD TIRE PRESSURE OF 65 PSI FRONT AND 70 PSI REAR UNLOADED NOT PULLING ANYTHING. UPON RETURNING TO PRESCOTT ARIZONA I TOOK IT TO TIMS GMC DEALER AND THE ALIGNMENT WAS OK. I EMAILED BRIDGSTONE THEY REFERRED ME TO THE PHOENIX BRIDGESTONE DEALER THEY SAID THE TIRES FOR THAT TRUCK SHOULD BE LT 245X75X17 FIRESTONE NOT BRIDGESTONE. THEY SAID THEY WOULD CHANGE THEM OUT BUT NEED AN OK FROM THE GMC DEALER. THE PRESCOTT TIMS GMC DEALER REFUSED TO ACCOMMODATE THE REQUEST. CHECKING WITH SEVERAL TIRE DEALERS IN PRESCOTT THE TIRE REQUIREMENTS FOR A 2500 TRUCK ARE A FULL 10 PLY TIRE NOT THE 7 PLY FACTORY INSTALLED TIRE. NOTE: THE BRIDGESTONE TIRE HAS A 2 PLY SIDEWALL..... A MICHELIN 10 PLY TIRE HAS A 3 PLY SIDEWALL THIS MAY BE PART OF THE PROBLEM. THE RIM WIDTH IS.....7.5............LOAD INDEX..121/118.......SPEED RATING........Q.... COLD PRESSURE OF 80 PSI

HEADLIGHTS AREN'T WIDE ENOUGH MAKING IT VERY DANGEROUS TO MAKE A LEFT OR RIGHT TURN AND VERY DANGEROUS IN MOUNTAINOUS AREAS GMC FINALLY PUT BRIGHTER BULBS IN AND HASN'T FIXED THE PROBLEM. THIS HAS BEEN ONGOING SINCE MAY 2014 AND GM DOESN'T CARE.

THE HEADLIGHTS DO NOT PROVIDE ADEQUATE LIGHTING OF THE ROAD WHICH MAKES IT VERY DIFFICULT TO DRIVE SAFELY AT NIGHT . I HAVE TRIED TO WORK THROUGH GMC THEY CHANGED THE BULBS TO A DIFFERENT VENDOR BUT DIDN'T HELP. GMC NOW IN THE 2016 ARE USING HID BULBS THEY ALSO USED A DIFFERENT LIGHTING SYSTEM IN THE 2014 . THE LOCAL GMC DEALER AGREES THAT THE LIGHTING COULD LEAD TO POSSIBLE ACCIDENT . THE LUMEN OF THE BULBS ARE DOWN AROUND 1200 WHICH IS HALF OF THE NORMAL LUMENS TO PROVIDE ADEQUATE STOPPING OR VISUAL OF THE ROAD. PLEASE HELP US OWNERS AS THIS VEHICLE IS VERY DANGEROUS TO DRIVE AFTER DARK. *DT

HAVING TIRE ISSUES WITH MY NEW 2015 GMC 2500 4WD PICK UP THE BRIDGESTONE TIRES THAT ARE INSTALLED AS FACTORY EQUIPMENT SIZE 265X70X17 LOAD RANGE 'E' THEY HAVE A TENDENCY TO WONDER AND AT TIMES AND NOT FOLLOWING A CURVE. THE ALIGNMENT WAS OUT AND REALIGNED BY GMC AT 7000 MILES. THE PROBLEM DIDN'T GO AWAY. I CALLED A BRIDGSTONE DEALER AND HE SAID THE TIRE SIZE WAS INCORRECT THEY NEED TO BE 245X75X17 LOAD RANGE 'E' FIRESTONE TIRES.GM IS REFUSSING TO PUT ON THE CORRECT SIZE. I CHECKED WITH MICHELIN AND THEY RECOMMEND 245X75X17 LOAD RANGE 'E' TIRES. THE NEW 2016 GM 2500 VEHICALS HAVE 245X75X17 LOAD RANGE 'E'.
