SERVICE BRAKES
ANTI-COLLISION SYSTEM IS ACTIVATED, I APPLY BREAKS, BREAK PEDDLE IS SOFT AND GOES TO THE FLOOR, I SWERVE TO AVOID COLLISION AND QUICKLY PUMP THE BREAKS TO REGAIN PEDDLE AND APPLY BREAKS AGAIN (THIS TIME BRAKES ENGAGE). 6 DIFFERENT TIMES THIS HAS HAPPENED. 4 TIMES ON THE INTERSTATE DURING RUSH HOUR AND TWICE ON A HIGHWAY. CAR IN FRONT OF ME SLAMMED ON THE BREAKS CAUSE THE SYSTEM TO ACTIVATE AND ME TO REACT. IT APPEARS THE SYSTEM OVERRIDES THE BRAKES TAKING CONTROL AWAY FROM ME. HOWEVER, THE SYSTEM DOES NOT BRAKE THE VEHICLE. ANOTHER OCCUR WAS WHEN I WAS LAUNCHING MY BOAT INTO THE LAKE. I WAS BACKING UP AND LOST BRAKE PRESSURE AND HAD TO APPLY MY EMERGENCY PARKING BRAKE TO STOP MY TRUCK FROM GOING INTO THE WATER. THIS VEHICLE HAS BEEN CHECKED BY 2 DIFFERENT DEALERS, 4 DIFFERENT TIMES IN THE PAST YEAR. I DO NOT FEEL SAFE DRIVING THIS VEHICLE. THE DATE LISTED BELOW WAS THE LAST OCCURRENCE WHEN THIS HAPPENED. (NOT THE PRIOR 5 OCCURRENCES)

SERVICE BRAKES
TOTAL BRAKE FAILURE. THE PEDAL BECAME HARD AS A ROCK WITH NO ADVANCE WARNING. I RECEIVED A NOTICE (N182202780) FROM GM STATING THAT I MIGHT EXPERIENCE INCREASED BRAKE PEDAL EFFORT. IT WENT ON TO SAY HOW THIS NOTICE "IS NOT A REACALL" AND THAT BRAKES STILL MEETS "ALL FEDERAL MOTOR VEHICLE SAFETY STANDARDS FOR BRAKE PERFORMANCE" I'M WRITING TO BRING ATTENTION TO THE FACT THAT MY TRUCK EXPERIENCED NO SYMPTOMS OF A PROBLEM UNTIL THE PEDAL HAD MAYBE 10% ASSIST. NO CHECK ENGINE LIGHT OR NOTICE FROM THE DRIVERS INFO CENTER. I APPLIED THE BRAKE, SHIFTED INTO DRIVE, ACCELERATED THEN APPLIED THE BRAKE TO STOP AND MAYBE HAD 10% BRAKING ABILITY. THE NOTICE ALSO WENT ON TO SAY THAT "FAILURE TO FOLLOW RECOMMENDED OIL CHANGE INTERVALS COULD CONTRIBUTE TO THIS CONDITION". THE TRUCK HAS 32000 MILES ON IT, I'VE OWNED IT SINCE NEW, I HAVE ALWAYS CHANGES OIL WITH 20% LIFE LEFT IN IT. THIS IS ABOUT 2000 MILE SOONER THAN THE MANUFACTURER RECOMMENDS. THIS IS A VERY SERIOUS CONDITION THAT GM HAS RECOGNIZED IN THERE LETTER, BUT IN MY OPINION, ARE NOT TAKING IT SERIOUS ENOUGH. UNLESS I'M A "ONE OFF" CASE, THIS WILL VERY LIKELY GET PEOPLE HURT AND PROPERTY DAMAGE IF NOT ADDRESSED VERY SOON. PLEASE LOOK INTO THIS, THANK YOU

POWER TRAIN, VEHICLE SPEED CONTROL
THE TRUCK LURCHES FORWARD AS IF THE ACCELERATOR IS BEING DEPRESSED WHILE COMING TO A STOP OBVIOUSLY WHILE DEPRESSING THE BRAKE. THIS CAUSES DANGEROUS SITUATIONS EVERY DAY IN TRAFFIC. I HAVE NOT FOUND ANY SOLUTIONS TO THE PROBLEM ONLINE. REPROGRAMMING COMPUTER AND REPLACING OTHER SPEED CONTROL MODULES HAS NOT SOLVE THE PROBLEM FOR OTHER DRIVERS.

PROBLEM CONTINUED UNTIL I WAS ARRIVED AT DESTINATION A QUARTER MILE AWAY. OCCURRED SEVERAL MORE TIMES. CUT VEHICLE OFF AND WHEN RESTARTED IT OCCURRED ONCE AND THEN RETURNED TO NORMAL OPERATION.

8 SPEED TRANSMISSION IS DANGEROUS. UNDER LIGHT THROTTLE, THE VEHICLE WILL MAKE A LOUD POPPING NOISE AND LURCH FORWRWARD. LIKE STOPPING AT A STOP LIGHT, DRIVING THROUGH A DRIVE-THRU. MY TRUCK WILL SHAKE VIOLENTLLY.. DEALER SAYS ITS THE TRANSMISSION. WHEN I TRY TO ENTER MY GARAGE THE TRUCK WILL SORT OF JUMP FORWARD. DELEAR SAYS ITS TORQUE CONVERTER SUTTER. TRANSMISSION HAS BEEN WORKED ON 3 TIME. IT SEEMS TO GET WORSE. DELEARS SAYS THE 8 SPEED TRANSMISSION HAS MANY ISSUES BUT GM DOES NOT HAVE A FIX. THESE 8 SPEED TRANSMISSIONS WILL END UP KILLING FOLK.. THIS STUFF HAPPENS ON A DAILY BASIS

MY TRUCK SHIFTS VERY HARD BETWEEN GEARS, ESPECIALLY 1ST TO 2ND. FEELS LIKE GETTING REAR ENDED SOMETIMES. IT ALSO HESITATES DAILY WHEN BACKING OUT OF MY DRIVEWAY AND PUTTING IT FROM REVERSE TO DRIVE. YOU DON'T KNOW WHEN IT WILL ACTUALLY ENGAGE MAKING IT DANGEROUS WHEN PULLING OUT INTO THE STREET. ITS DEFINITELY AN ISSUE WITH THE TRANSMISSION BUT NO FIXES OFFERED FROM DEALER YET.

"HAVE TAKEN MY 2017 GMC SIERRA INTO THE DEALERSHIP TWICE FOR TRANSMISSION ISSUES, THE LAST TIME WAS A MONTH AGO. BOTH TIMES I WAS TOLD THAT THERE WASN'T ANYTHING WRONG BUT THAT THE TRANSMISSION SOFTWARE WAS 'RE-FLASHED' AND THAT THE TRANSMISSION WOULD HAVE TO 'RE-LEARN MY DRIVING HABITS'. MY TRUCK IS STILL HAVING PROBLEMS. WHILE UPSHIFTING FROM 1ST TO 2ND GEAR, THE TRANSMISSION SOMETIMES HESITATES BEFORE IT ENGAGES AND THEN CAUSES THE TRUCK TO LUNGE FORWARD WITH A HUGE SLAM. WHILE DOWNSHIFTING FROM 2ND TO 1ST GEAR, THE TRANSMISSION WILL MAKE A VERY NOTICEABLE 'CLUNK'. I'M ABOUT TO TAKE IT BACK A 3RD TIME. THIS IS EXTREMELY FRUSTRATING MY BOUGHT MY TRUCK LESS THAN 2 YEARS AGO AND IT ONLY HAS 25,000 MILES."

ELECTRONIC STABILITY CONTROL (ESC), STEERING
THE STABILITRAK SENSOR KEEPS GOING ON AND OFF. I'VE HAD THIS ISSUE WHEN I FIRST GOT THE TRUCK IN THE END OF OCTOBER IN 2017. THE DEALERSHIP COULD NOT FIX IT AT FIRST BUT FINALLY HAD TO FIX SOME WIRING. I'VE SEEN IT GO ON A FEW TIMES SINCE THEN BUT NEVER STAYED ON. AND FOR ABOUT 2-3 WEEKS IT'S BEEN COMING ON AND OFF BUT STAYING MORE ON AND NOT GOING AWAY NOW. I FEEL LIKE THIS SHOULDN'T HAPPEN TO A NEWER TRUCK

THE BRAKE PEDAL BECOMES EXTREMELY STIFF WHEN TRYING TO STOP AT SLOW SPEEDS, ESPECIALLY IN PARKING LOTS. THE VEHICLE BECOMES VERY DIFFICULT TO STOP ALMOST CAUSING CRASHES. GM DEALERSHIP REPEATEDLY TESTS VEHICLE AND TRIES TO CLAIM THERE IS NOTHING WRONG AND I'M MAKING A MISTAKE. HAD TO TAKE VEHICLE IN SEVERAL TIMES AND EVENTUALLY THEY FOUND A FAILED VACUUM PUMP. THEY TRIED TO MAKE ME PAY $700+ FOR THE REPAIR EVEN THOUGH ITS A KNOWN ISSUE. THEY ARE TRYING TO AVOID DOING A RECALL AND PUTTING THEIR BOTTOM LINE AHEAD OF SAFETY. THESE TRUCKS ARE DANGEROUS.

SERVICE BRAKES
THE BRAKES ARE NOT WORKING AT SLOW SPEEDS. I WAS PARKING IN A PARKING GARAGE WHILE PULLING UP TO THE CONCRETE WALL AND PUSHING ON THE BRAKE THE TRUCK ALMOST DIDN'T STOP AND THE PEDAL GOT VERY STIFF. WHILE DRIVING HOME IN TRAFFIC THE TRUCK DID THE SAME THING AND I ALMOST HIT THE CAR IN FRONT OF ME. IT SEEMS TO BE AT SLOWER SPEEDS AND THE BRAKES ARE LOSING ALL POWER. THE TRUCK IS ONLY 2 YEARS OLD AND NORMALLY STOPS ON A DIME. TOOK TO THE DEALER TODAY, AND THEY SAID THE VACUUM PUMP IS BAD AT ONLY 39,000 MILES.
