STEERING
VEHICLE WAS PARKED AT WORK. STARTED THE VEHICLE TO GO HOME AND BACKED OUT OF SPACE AND THAT IS WHEN THERE WAS NO STEERING AVAILABLE. I COULD ONLY GO BACK. SO BACKED IT INTO ANOTHER PARKING SPACE, AND HAD TO LEAVE THE VEHICLE UNTIL THE NEXT MORNING WHEN I HAD IT TOWED TO THE NEAREST GM DEALERSHIP. THEY NOW TELL ME THAT THE MODULE IS DEAD AND THAT IT WILL COST US TO REPLACE THIS. ALSO WHEN REPLACING THE MODULE, IF THEY FIND THE STEERING RACK NEEDS TO BE REPLACED, WE WILL BE RESPONSIBLE FOR THIS AS WELL, ON TOP OF LABOR CHARGES. I HAD ONLY RECENTLY PURCHASED THIS VEHICLE 7 MONTHS AGO. I AM VERY DISAPPOINTED WITH THE RESPONSE FROM GMC IN THIS MATTER.

VISIBILITY/WIPER
SITTING IN A PARKING LOT ALLOWING THE PICKUP TO WARM UP, THE REAR DEFROSTER WAS ON AND STARTED HAVING A CRACKLING SOUND AND SMOKING. THE NOISE AND SMOKE STOPPED WHEN THE REAR DEFROSTER WAS TURNED OFF, HOWEVER APPROXIMATELY A MINUTE LATER THE WINDOW SHATTERED AND SPRAYED GLASS SHARDS INTO THE CAB AND ON THE BACK SEAT. THE PICKUP WAS STATIONARY AND THERE WAS NO POSSIBILITY THAT THIS WAS CAUSED BY AN IMPACT. BASED ON THE PATTERN OF BROKEN GLASS IT COULD BE SEEN COMING FROM THE CORNER OF THE WINDOW WHERE THE HEATING ELEMENT IS. I CALLED GM AND THEY INDICATED THEY WOULD NOT LOOK AT THE VEHICLE FOR AT LEAST 30 DAYS TO EVEN DETERMINE THE ISSUE.

EXTERIOR LIGHTING
THE HEADLIGHTS ARE COMPLETELY INADEQUATE. IF YOU ARE TAKING A TURN AT NIGHT, THE LIGHTS CONTINUE TO STAY STRAIGHT WITH THE DIRECTION OF THE VEHICLE INSTEAD OF FOLLOWING THE VEHICLE SO THAT YOU END UP TAKING A TURN BLINDLY AND CANNOT SEE THE CURB OR EDGE OF THE ROAD. IT IS A TOTALLY UNSAFE SITUATION. WE HAVE FOUND THAT YOU MAY HAVE A BIT MORE VISIBILITY IF YOU RUN WITH THE FOG LIGHTS ON, BUT VERY LITTLE IMPROVEMENT. PLEASE FIND A SOLUTION, ADDITIONAL HEADLIGHT, AS THIS TRUCK IS VERY SCARY TO DRIVE AT NIGHT.

UNKNOWN OR OTHER
I WAS WARMING THE TRUCK UP IN THE MORNING WITH THE AUTO START, PARKED, AND HAD THE AUTO DEFROST TURNED ON FOR THE REAR. WHEN I ENTERED THE TRUCK AND CLOSED THE DOOR THE REAR PASSENGER WINDOW THAT IS FACING THE BED, SHATTERED. I'M ASSUMING THE DEFROST IS RUNNING TOO HOT AND WEAKENED THE GLASS OR SOMETHING RELATED TO THE ISSUE. I KNOW OF SEVERAL OTHER PEOPLE THAT HAVE THIS PROBLEM AS WELL.

SERVICE BRAKES
I WAS DRIVING DOWN A HILL AT ABOUT 15 MILES AN HOUR AND WHEN I WENT TO PRESS THE BRAKE PEDAL I HEARD A NOISE AND THE BRAKE PEDAL WENT TO THE FLOOR AND TRUCK WOULD NOT STOP. I HAD TO SWERVE OFF THE ROAD TO AVOID A COLLISION. AFTER, THE BRAKE PRESSURE RETURNED WHILE DRIVING, BUT WHEN STOPPED IT WOULD LOSE PEDAL FEEL AND GO BACK TO THE FLOOR. AFTER READING ARTICLES IT WAS OBVIOUS THE VACUUM PUMP WAS FAILING. I LIMPED THE TRUCK HOME AND TOOK IT TO THE DEALERSHIP AND AM WAITING TO HEAR BACK.

SERVICE BRAKES
THERE IS A KNOWN BRAKE PROBLEM CAUSED BY FAULTY VACUUM PUMP. WITH THE VACUUM PUMP FAILING THERE WILL BE LOSS OF ASSISTED BRAKING. SOME PEOPLE HAVE NOTED REQUIRING 2 FEET TO STOMP ON THE BRAKES TO STOP THE TRUCK. THE DANGEROUS BRAKING PROBLEM SEEMS TO HAPPEN DURING LOW SPEEDS. SOME MEMBERS ON THE FORUMS HAVE MENTIONED GETTING INTO ACCIDENTS. GMC DOES NOT COVER THE VACUUM PUMP UNDER THEIR WARRANTY WHICH IS RIDICULOUS. I HAVE LISTED SOME FORUM THREADS AS PROOF OF NOT JUST ME HAVING THIS ISSUE.

EXTERIOR LIGHTING
THE PROJECTOR HEADLIGHTS THAT ARE INSTALLED IN THIS VEHICLE FROM THE FACTORY DO NOT PROVIDE ADEQUATE VISIBILITY AT NIGHT. I AM UNABLE TO SEE MORE THAT 15 FEET IN FRONT OF THIS VEHICLE FROM A SAFETY PERSPECTIVE. I HAVE RETURNED THE VEHICLE TO THE DEALER MULTIPLE TIMES FOR REPAIR. THEY CHANGED THE BULBS BUT STATED THEY ARE WORKING WITHIN DESIGN SPECIFICATIONS AND SAID THAT GM HAD USED A NEW TYPE OF LIGHTING SYSTEM IN 2015 BUT REALIZED IT IS WAS NOT ADEQUATE AND REDESIGNED IN LATER MODEL YEAR. IF GM REALIZES THEY HAVE A PROBLEM WHY WILL THEY NOT REPAIR VEHICLES THAT THEY SOLD PRIOR TO REALIZING THEIR MISTAKE? IN THE RAIN AT NIGHT THERE IS VIRTUALLY ZERO VISIBILITY. GM NEEDS TO FIX THIS PROBLEM AS IT IS A MAJOR SAFETY ISSUE.

SERVICE BRAKES
IT STARTED HAPPENING A WEEK OR SO AGO WHERE WHEN IN REVERSE OR AFTER SWITCHING FROM REVERSE TO DRIVE AND TRYING TO BRAKE THE PEDAL WOULDN'T COMPRESS, IT WAS AS IF THEY WERE LOCKING UP ON ME. I WOULD HAVE TO PUT MOST OF MY BODY WEIGHT ON THE PEDAL TO EVEN GET THE TRUCK TO STOP, TO THE POINT WHERE I ALMOST RAN INTO MY NEIGHBORS CAR BACKING OUT OF THE DRIVEWAY. IT SEEMED TO MAINLY HAPPEN AT SLOWER SPEEDS, IN BOTH DRIVE AND REVERSE AS IT HAPPENED ON MORE THAN ONE OCCURRENCE. LUCKILY I DECIDED TO TAKE IT TO THE GMC DEALER BEFORE ANYTHING SERIOUS HAPPENED, BUT THIS IS A HUGE SAFETY CONCERN AND I FEEL IT NEEDS TO BE ADDRESSED. THE DEALER ALSO KNEW EXACTLY WHAT THE ISSUE WAS BEFORE I COULD GIVE THEM ANY INFORMATION, SO IT SEEMS LIKE THIS IS A COMMON PROBLEM. THEY REPLACED MY VACUUM PUMP AND WE WILL SEE IF THAT FIXES THE PROBLEM.
