2015 GMC SIERRA 1500 Complaints

DURING REAL SLOW SPEED MY BRAKES WILL GET EXTREMELY HARD TO PRESS. DURING THIS TIME THE TRUCK WILL BECOME HARD TO STOP. THIS USUALLY HAPPENS WHEN PARKING OR IN A DRIVE- THRU.

2015 GMC SIERRA 1500. HAD THE BRAKE PUMP VACUUM RECALL PERFORMED NOT TOO LONG AGO. THIS ISSUE ACTUALLY SEEMS WORSE NOW. I WAS BACKING OUT OF A PARKING SPOT - LOW SPEED WAS THE ISSUE PREVIOUSLY- AND APPLIED THE BRAKE. NOTHING HAPPENED, NO BRAKES (PEDAL WAS DEPRESSED) TRUCK CONTINUED TO BACK OUT AND I HAD TO JAM ON THE BRAKE AGAIN, ONLY THEN DID THE TRUCK BRAKE SYSTEM SHUDDER AND ENGAGE ENOUGH FOR ME TO STOP. THIS HAPPENS AT LOW LOW SPEEDS - CRAWLING TRAFFIC, PARKING LOTS ETC.... I GOT TO TAP THE BRAKE PEDAL TO SLOW A BIT AND NOTHING OCCURS - OR THE PEDAL PUSHES BACK AT ME GIVING ME NO BRAKES. I HAVE TO COMPLETELY DISENGAGE THE PEDAL AND THEN FORCEFULLY ENGAGE THE PEDAL AGAIN TO GET ANY KIND OF BRAKING. I HAVE ONLY NOTICED THIS AT VERY SLOW SPEEDS. THIS IS TERRIBLY SCARY WHEN WE ARE CRAWLING DOWN A STEEP MOUNTAIN HIGHWAY WITH BUMPER TO BUMPER TRAFFIC AND I GET NO BRAKE RESPONSE. LIKE I SAID, THE TRUCK WENT IN FOR A RECALL THAT WAS SUPPOSED TO HAVE FIXED THIS ISSUE.

SYMPTOM OF HOT AIR BLOWING WHILE USING THE A/C, STATIONARY OR WHILE OPERATING. FILLED WITH COOLANT WHICH ONLY LASTED ABOUT ONE WEEK. REVIEWED FORUMS AND TSB'S TO NOTE A COMMON ISSUE WITH THE CONDENSER. DEALER WANTED TO DIAGNOSE AND REPLACE ITEMS IN ORDER THAT DID NOT INCLUDE REPLACING THE CONDENSER AT THE TOP OF THAT LIST. PURCHASED A THIRD PARTY CONDENSER, VACUUM PUMP, AND NECESSARY FLUIDS AND ACCESSORIES AND REPLACED BY MYSELF. A/C HAS BEEN WORKING RELIABLY FOR SEVERAL MONTHS. ALTHOUGH I SAVED ABOUT 2K DOLLARS (ALL MATERIALS COST ABOUT 500 HUNDRED DOLLARS), IT'S CLEAR THAT THIS ISSUE IS KNOWN AND SHOULD BE A RECALL.

TRUCK CONTINUES TO LOSE BRAKES AT LOW SPEEDS OR WHEN BACKING/PULLING TRAILER. TRUCK WAS SERVICED FOR BRAKE RECALL AND NO CHANGE TO BRAKING. CONSISTENTLY LOOSES BRAKING WHEN PARALLEL PARKING OR BACKING INTO PARKING SPOTS ALONG WITH STOP AND GO TRAFFIC BRAKES GO OUT AND YOU MUST STAND ON THE PEDAL TO STOP THE TRUCK. THIS BRAKING ISSUE HAPPENS ALMOST DAILY.

TL* THE CONTACT OWNS A 2015 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 35-50 MPH, THE CONTACT NOTICED A MINOR SHAKING COMING FROM THE VEHICLE. THE CONTACT TOOK THE VEHICLE TO LOVE BUICK GMC (736 SATURN PKWY, COLUMBIA, SC 29212; (803) 732-6500) WHO FLUSHED AND REFILLED THE TRANSMISSION FLUID HOWEVER, THE FAILURE RECURRED. THE CONTACT RETURNED THE VEHICLE TO THE SAME DEALER WHO PERFORMED ANOTHER TRANSMISSION FLUSH HOWEVER, THE FAILURE PERSISTED. THE CONTACT STATED THAT THE VEHICLE DROVE ROUGH AND THAT THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT USED A DTC SCANNER AND RETRIEVED A CODE RELATED TO THE TRANSMISSION CONTROL MODULE AND TEMPERATURE SENSOR. THE VEHICLE WAS THEN TAKEN STOKES TRAINOR CHEVROLET CADILLAC BUICK GMC (2004 WILSON RD, NEWBERRY, SC 29108; (803) 792-4763) AND THE CONTACT WAS INFORMED THAT THE INTERNAL WIRING HARNESS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE AND INFORMED THE CONTACT THAT THE VIN WAS INCLUDED IN A SPECIAL COVERAGE PROGRAM. THE APPROXIMATE FAILURE MILEAGE WAS 75,000.

FUEL GAUGE READS EMPTY ALL THE TIME. WAS WORKING, AFTER SITTING FOR 2 WEEKS, IT DIDN'T.

THE BRAKES FAILED AS MY SON APPROACHED AN INTERSECTION. SUBSEQUENTLY, HE STRUCK ANOTHER VEHICLE BROADSIDE. EXTENSIVE DAMAGE WAS SUSTAINED TO BOTH VEHICLES. THE DRIVER REPORTED THAT HE PRESSED THE BRAKE PEDAL, BUT THE TRUCK WOULD NOT STOP. AFTER I INVESTIGATED FURTHER FOR AN EXPLANANTION,I DISCOVERED THAT THERE WAS A RECALL ON HIS BRAKE SYSTEM THAT MIGHT EXPLAIN BRAKE FAILURE. THE CRASH OCCURRED ON A CITY STREET.

WHEN I WAS DRIVING MY TRUCK OFF THE HIGHWAY ONTO THE MAIN ROAD WHERE I WAS GOING I NOTICED THERE WAS AN ISSUE WITH MY TRUCK. AFTER COMING TO A STOP AT A RED LIGHT ONCE IT TURNED I ACCELERATED AND SUDDENLY FELT A JERK FROM THE TRUCK AND HEARD A LOUD WHISTLING NOISE. IT DID THIS MULTIPLE TIMES ABOUT 5-6 TIME EVERY TIME I WOULD ACCELERATE FROM A SPEED OF 30-40. I DECIDED TO DROP IT OFF AT MY LOCAL GMC TO GET IT LOOKED AT. THEY CALLED ME THE NEXT DAY TO PICK IT UP SINCE THEY RAN IT THROUGH DIAGNOSTICS AND DIDN'T FIND AN ISSUE WITH THE VEHICLE. ONCE I GOT THERE I DEMANDED FOR THE MECHANIC TO COME DRIVE THE TRUCK WITH ME TO SEE WHAT THE ISSUE WAS AND THEY DECIDED THEY NEEDED TO KEEP IT FOR A COUPLE OF DAYS TO GET IT LOOKED AT. THEY THEN CALLED TWO DAYS AFTER AND SAID THAT THE TRANSMISSION WAS MESSED UP AND NEEDED A NEW ONE TOTALING THE COST TO $5346.07 WHICH IS CERTAINLY NOT SOMETHING WE CAN AFFORD RIGHT NOW! I DON'T UNDERSTAND HOW THEY DIDN'T SEE THE ISSUE THE FIRST TIME THEY DIAGNOSED IT?? THIS IS SOMETHING THAT NEEDS TO GET RECALLED I HAVE SEEN MANY SIMILAR ISSUES.

THE VEHICLE IS STALLING WHEN BRAKING AND GETTING READY TO TURN. MY TRUCK IS SHOWING STABILITRAK SERVICE INTERMITTENTLY AND I'VE ALMOST BEEN IN A CRASH 3 TIMES BECAUSE OF THIS. THE VEHICLE ONLY RESTARTS AFTER PLACING IN PARK. THIS IS NOT SAFE WHEN IN TRAFFIC. THERE SEEMS TO BE NO RECALLS AND NO KNOWN CAUSE. SOMEONE IS GOING TO DIE IF GM DOESN'T FIX THIS. I'VE BEEN ON FORUMS AND IT'S A COMMON PROBLEM. IT SHOULD BE FIXED BY GM IF IT IS SO COMMON. THIS HAPPENS WHEN APPROACHING CROSS TRAFFIC AT AN INTERSECTION AND I LOSE ALL CONTROL OF STEERING BRAKING AND POWER TO THE TRUCK.

WHILE DRIVING THE TRANSMISSION SLIPPED WHILE ATTEMPTING TO CHANGE GEARS. THIS CAUSED THE VEHICLE TO BE UNRESPONSIVE AND INDICATE A PROBLEM ACCELERATING. THIS HAS BEEN GETTING WORSE OVER THE PAST SEVERAL MONTHS AND ENDED UP LEAVING ME IN A VERY DANGEROUS SITUATION YESTERDAY WHILE DRIVING.
