2015 GMC SIERRA 1500 Complaints

VEHICLE HAS ROUGHLY 52,000 MILES ON IT. NOTICED LEAK ON PASSENGER SIDE, FRONT. OPENED HOOD, NOTICED FLUID DRIPPING DOWN RADIATOR. TOOK TO GARAGE, DEALER IDENTIFIED RADIATOR AND AC SYSTEM HAD LEAKS. NOT COVERED UNDER WARRANTY.

VIOLENT AND ERRATIC SHIFTING DURING ACCELERATION AND DECELERATION... A SIMULTANEOUS POP AND JERK HAPPENS... ALSO WHEN ACCELERATING AND HITTING PASSING GEAR THE TRUCK SEEMS TO STALL OUT AND THEN QUICKLY ENGAGES TO APPLY MORE POWER THAN EXPECTED... THIS CAN BE DANGEROUS FOR A DRIVER ATTEMPTING TO MERGE ONTO HIGHWAYS/HIGHWAYS! THE JERKING OCCURS ON A REGULAR BASIS AND AT VARIOUS SPEEDS ON VARIOUS HIGHWAYS...

IT HAS A PROBLEM WITH CYCLING OF THE THERMOSTAT THAT CAUSES STRESS FRACTURES ON THE RADIATOR LEADING TO COOLANT LEAKS. ATTACHED ARE GM BULLETINS ON THE 2014 AND 2015 MODELS. AS ONE CAN SEE THEY HAVE PROVIDED SPECIAL COVERAGE. MY RADIATOR IS LEAKING JUST LIKE THE SERVICE BULLETIN SAYS. THIS NEEDS TO BE RECALL.

REAR WINDOW DEFROSTER STARTED SMOKING AND CREATED A BURNING PLASTIC SMELL. AFTER TURNING OFF THE REAR DEFROSTER THE REAR WINDOW EXPLODED/SHATTERED IN PLACE. I SEE THERE IS A RECALL IN CANADA, BUT NOT HERE. THIS IS HAPPENING HERE AND I HAVE READ OF MANY OTHERS WITH SAME ISSUE. FIRE AND BROKEN GLASS IS NOT SAFE AND SHOULD BE ADDRESSED

VEHICLE WAS STATIONARY ON THE STREET, PARKED. I ENTERED IT, AND TURNED ON MY FRONT AND REAR DEFROSTERS WITH THE SETTING ON "HI." I TURNED AROUND AND VERIFIED THAT MY VEHICLE HAD NOT BEEN HIT NOR WAS ANY DAMAGE AT ALL APPARENT TO ME. AT SOME POINT AS I SAT THERE WITH THE CAR IDLED AND THE HEATED AIR REACHING ITS MAXIMUM TEMPERATURE, I BEGAN TO SMELL SOME FOUL SMELL IN THE CAB THAT I BELIEVED WAS EXHAUST ENTERING THE CABIN. I ROLLED DOWN THE WINDOW. AS I BRUSHED THE SNOW FROM THE FRONT AND BEGAN TO DRIVE AWAY, I HEARD A NOISE THAT I BELIEVED WAS THE SNOW FALLING FROM THE ROOF. HOWEVER, AS I ROLLED AWAY, I NOTICED A LOUDER-THAN-NORMAL CABIN. UPON LOOKING BEHIND ME, I NOTICED THE REAR RIGHT WINDOW WITHIN THE SLIDING REAR CABIN WINDOW HAD BLOWN OUT. UPON INSPECTING THE AREA, I NOTICED THAT NO SNOW OR WATER WAS PRESENT INSIDE. GIVEN THAT WE HAD RECEIVED A LOT OF SNOW THE PREVIOUS EVENING THROUGH THE MORNING, HAD THE DAMAGE OCCURRED THROUGHOUT THE EVENING OR EARLY MORNING, THERE WOULD'VE BEEN MOISTURE PRESENT.

VACUUM ISSUE WITH BRAKES. BACKING UP VEHICLE WITH UTILITY TRAILER WHEN BRAKE PEDAL IS PRESSED THEIR IS HESITATION AND LACK OF EASE WHEN PRESSING PEDAL. THEN IF PRESS PEDAL AFTER THAT THERE IS NO MOVEMENT AND PEDAL IS LIKE PUSHING ROCK WITH FOOT, NO SOFTNESS, NO MOVEMENT ALL. HAVE NOTICED THIS OCCASIONALLY FOR THE PAST 8 OR 10 MONTHS BEFORE FINDING THIS PLACE HERE TO NOTE MY ISSUE

AT LOW SPEEDS THE BRAKE PEDAL IS NON-RESPONSIVE AND PULSES WHILE MAKING A NOISE. IT HAS HAPPEN TWICE, ONCE IN A DRIVE THRU AND ANOTHER TIME BACKING OUT OF A PARKING SPOT. APPEARS TO BE A VACUUM ASSIST ISSUE. ONCE THE TRUCK WAS PLACE IN NEUTRAL AND THE RPM'S WERE INCREASED THE ISSUE WENT AWAY

AA SOON AS THE WARRANTY EXPIRED ON MY TRUCK IT START HAVING PROBLEMS WITH THE TRANSMISSION 🥴

USED THE REMOTE START TO WARM THE TRUCK UP. GOT IN AND WAS LEAVING MY DRIVEWAY AND THE REAR WINDOW EXPLODED. READ DEFROST WAS ON SINCE WE RECEIVED 6+ INCHES ON SNOW TODAY.
