AT STARTUP, IF YOU SHIFT FROM PARK TO DRIVE OR REVERSE, THE BRAKE PEDAL STIFFENS AND IT IS HARD TO STOP. IF YOU ARE ABLE TO SPEED UP OVER A CERTAIN SPEED, SAY 15 TO 20 MPH, THEN THE TRUCK BRAKES FINE. I HAVE TAKEN IT TO THE DEALER AND THEY REPLACED THE BRAKE BOOSTER PUMP, BUT IT STARTED DOING IT AGAIN WITHIN A DAY OR TWO.

SERVICE BRAKES
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.

UNKNOWN OR OTHER
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.

SERVICE BRAKES
I HAD A SEVERE SHUDDER WHEN BRAKING. I TOOK APART THE FRONT BRAKES AND DID NOT FIND ANYTHING. WHEN I TOOK OFF THE REAR DRUM I FOUND THAT THE WASHERS ON THE HOLD DOWN SPRINGS HAD FAILED AND ALLOWED THE PIN TO PULL THROUGH. (MAKING A CROSS IN THE WASHER WHERE THERE SHOULD ONLY BE A SLOT) THE RELEASED THE SPRING AND WASHER TO FALL. THE SHOES WERE JUST SITTING THERE NOT SECURED TO THE BACK PLATE OF THE WHEEL. THE SECOND SIDE HAD ALMOST FAILED AND THE WEAR ON THE WASHER IS VISIBLE IN MY ATTACHED PHOTOS.

WHILE DRIVING MY GMC SIERRA DENALI THE TRANSMISSION SHUDDERS REALLY BAD. I HAVE A 2017 WITH JUST 13,200 MILES ON IT. I WAS PULLING MY BASS BOAT AND THE SHURDDER WAS SO BAD MY DASH WAS SHAKING AND THE STEERING WHEEL WAS ALSO .I HAVE HAD THE FLUID CHANGED AT THE DEALERSHIP AND IT SHIFTED FINE AND DID NOT SHUDDER UNTIL IT REACHED AROUND 1000 MILES AFTER FLUID CHANGE AND IT IS DOING IT WORSE NOW THAN BEFORE. I TOOK IT TO THE DEALER CLOSE TO ME AND THEY INFORMED ME TODAY THEY WERE GOING TO DO NOTHING AND THEY TOLD ME TO TAKE IT BACK TO THE DEALER I BOUGHT IT FROM! THIS IS UNACCEPTABLE! I UNDERSTAND FROM ALL I HAVE BEEN READING ABOUT THIS PROBLEM GM STILL IS BUILDING AND SELLING TRUCKS WITH THE 8 SPEED TRANS IN THEM AND STILL HAVING PROBLEMS. REALLY? I GUESS I WILL KEEP DRIVING MINE AND I HOPE THE TRANSMISSION JUST COMES APART THEN THEY WILL GIVE ME ANOTHER TRANSMISSION DOING THE SAME THING! JUST GREAT GM!

SERVICE BRAKES
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.

APPARENTLY, THE 8 SPEED AUTOMATIC TRANSMISSION HAS ISSUES WITH WIRING HARNESS AND HARD SHIFTING WHICH THE MANUFACTURER HAS 18 SERVICE BULLETINS OUT ON YET STILL WILL NOT RECALL AND FIX PROBLEMS. ALSO THE BRAKE SYSTEM IS FAULTY AND UNSAFE IT LOSES PRESSURE AND EVEN BRAKING AT VARIOUS SPEEDS. AFTER TAKING IT TO THE DEALERSHIP THEY CAN NOT FIGURE OUT WHY AND SAY IT IS VARIOUS PARTS AND SHOULD BE RECALLED BUT IT IS NOT AS OF YET. GM KNOWS OF THESE ISSUES AND THE 1000S OF DOLLARS CUSTOMERS HAVE TO PAY FOR THESE REPAIRS. THIS IS WRONG AND NEEDS TO BE RECTIFIED.

I HAVE HAD TO REPLACE MY CONDENSING UNIT TWO DIFFERENT TIMES. ONCE AT 75,000 MILES, WHICH WAS COVERED BY MY EXTENDED WARRANTY THAT I PURCHASED, NOT BY GM, AND THE OTHER BROKE AT 107,000 MILES IN THE EXACT SAME SPOT, WHICH I HAD TO PAY FOR. THIS IS A JOKE! I HAVE ALSO HAD TO REPLACE MY OIL COOLING LINES TWO DIFFERENT TIMES, WHICH WERE ALSO NOT COVERED UNDER WARRANTY.

SERVICE BRAKES
I BOUGHT MY GMC BRAND NEW WITH 25 MILES ON IT. THE FIRST TIME I HAD A BRAKING ISSUE WAS PULLING INTO WORK. I HAD ROUGHLY 56,500 MILES ON THE TRUCK AT THIS POINT. I WAS COMING IN CAUTIOUSLY DUE TO A HEAVY TRAFFIC AREA. AS I PULLED INTO MY PARKING SPOT I ENGAGED THE BRAKES. THE PEDAL WAS SOFTER THAN USUAL. I PUSHED DOWN HARDER AND I CAME TO A SLOW ROLLING STOP. I THOUGHT I WAS GOING TO HIT THE BUILDING. I LET THE TRUCK SIT/RUN 5MIN, (I AM MECHANICALLY INCLINED, WAS IN AUTOMOTIVE TECH COURSES FOR 3 YEARS) I CHECKED THE BRAKES/BRAKE FLUID AND TRIED THE BRAKES IN THE REVERSE GEAR. LET THE TRUCK CREEP BACK AND TESTED THE BRAKES. THEY WERE NORMAL AGAIN. I CALLED THE DEALERSHIP AND MADE AN APPOINTMENT.(UPLOADED SERVICE PAPERWORK). DEALER SAID THERE WASN'T A RECALL AT THIS TIME BUT WANTED ME TO DO A BRAKE FLUID FLUSH BUT I WASN'T IN WARRANTY ANYMORE SO IT WAS GOING TO COST ME OVER 100+ DOLLARS. THAT'S WHY I REFUSED THE SERVICE. THE WINTER MONTHS GO BY AND MY BRAKES ARE FINE. THE SECOND TIME I NOTICED THIS ISSUE, WAS SPRING TIME THE FOLLOWING YEAR, I WAS PUTTING MY PONTOON BOAT IN THE WATER. BACKING INTO THE WATER I WENT TO STOP AND MY TRUCK KEPT ROLLING INTO THE WATER. I ENGAGED THE EMERGENCY FOOT BRAKE. I PULLED FORWARD AND THE BRAKES WERE BACK TO NORMAL. I TEST DROVE THE TRUCK IN THE EMPTY PARKING LOT THIS TIME, SEE IF IT WOULD HAPPEN AGAIN. CALLED THE DEALERSHIP AND ASKED IF THERE WAS A RECALL AND THEY SAID NO. BRAKES ARE BACK TO NORMAL AT THIS POINT. FINALLY THAT YEAR I RECEIVED A RECALL NOTICE IN THE MAIL. I WENT TO THE DEALERSHIP COMPLETED THE RECALL. I THOUGHT EVERYTHING WAS FIXED. APPARENTLY NOT. I WAS STUCK IN A TRAFFIC JAM AT A SLOW ROLL, BRAKING MORE FREQUENTLY AND THE PEDAL WENT SOFT AND TO THE FLOOR AGAIN. I ALMOST HIT THE VEHICLE IN FRONT OF ME. I STOPPED JUST IN THE NICK OF TIME. I AM NOW CURRENTLY WORKING WITH THE DEALERSHIP TO GET THIS BRAKE ISSUE RESOLVED.

ELECTRONIC STABILITY CONTROL (ESC), ELECTRICAL SYSTEM, STEERING
THE VEHICLE WAS IN MOTION AND TOOK A TURN THE DASHBOARD CHIMED AND SHOWED A "SERVICE STABILITRAK", AND REDCUTION IN POWER STEERING, AND HVAC WENT OFF AND CAME BACK ON AND I LOST POWER STEERING. EVERYTHING FLASHED AND FLICKERED. UPON FURTHER ASSESSMENT AT MY HOUSE STATIONARY TURNING THE WHEEL REACTIVATED THE PROBLEMS AND IT WAS ALSO NOTICED THAT THE LIGHTS WOULD FLICKER AND GO DIM ALONG WITH THE DASHBOARD LIGHTS. LOOKED UP SOME RECALLS AND SAW SOME RECALLS ON 2014 GMC SIERRA WITH LOSS IN POWER STEERING, HOWEVER MY VEHICLE WAS NOT INCLUDED IN THAT. I HAVE A BRAKE RECALL THAT I WILL BE SERVICING AND HOPEFULLY THAT MIGHT SOLVE THIS DANGEROUS ELECTRICAL PROBLEM.
