2015 CHEVROLET SILVERADO 1500 Complaints

I WAS DRIVING TO THE STORE WITH MY FAMILY EVERYTHING FILLS FINE WHEN I GET TO THE PARKING LOT I TRY TO STOP AND MY TRUCK JUST KEEP GOING I HAVE TO USE THE PARKING BRAKE TO STOP THE TRUCK I DRIVE AROUND TO MAKE SURE THAT HAPPENS BECAUSE IS A NEW TRUCK IT THAS IT AGAIN SO NOW MY TRUCK IS PARKED ON MY HOUSE BECAUSE IS NOT SAFE TO DRIVE

GOING THROUGHT DOWN TOWN TRAFFIC AND THE BRAKES WOULD NOT WORK. IT FELT LIKE I WAS PUSHING ON A BRICK. THEN HAD TO USE EMERGENCY BRAKE IN TRAFFIC FOR TWO HOURS.MY BOSS HAS SAME TRUCK AS I DO AND ONE WEEK LATER HAD THE SAME THING HAPPEN EXCEPT HE HIT THE WALL AT HIS HOME. I HAVE SPOKEN WITH SEVERAL OTHER EMPLOYEES AND ALL HAVE EXPERIENCED THIS PROBLEM. IT COST ABOUT 800 DOLLARS TO FIX IT

BRAKES FAIL AT LOW SPEED. PROBLEM DIAGNOSED BY CHEVROLET DEALER AND DETERMINED TO BE THE SAME PROBLEM AS OUTLINED IN CHEVROLET TECHNICAL SERVICE BULLETIN PIT5361B. GM NOT COVERING REPAIR AS THEY CLAIM NOTHING IS WRONG AND THE VEHICLE IS OUT OF WARRANTY.

YESTERDAY (18-MAR-2019), I WAS PULLING INTO A PARKING SPACE AT A RESTAURANT AND ALL OF A SUDDEN WHEN I TRIED TO APPLY MY BRAKES ON MY 2015 CHEVROLET SILVERADO 1500 CREW CAB, THE PEDAL WAS EXTREMELY HARD TO PUSH. THE TRUCK CONTINUED MOVING AFTER I EXERTED AS MUCH FORCE AS I COULD ON THE PEDAL. LUCKILY THE CURB ASSISTED IN STOPPING THE TRUCK BEFORE I CRASHED INTO A WALL AS I HAD MY TWO YOUNG CHILDREN IN THE VEHICLE WITH ME AT THE TIME. I AM ALSO GLAD MY WIFE WAS NOT DRIVING THE VEHICLE AT THE TIME. I DON'T BELIEVE THAT SHE WOULD HAVE HAD ENOUGH FORCE TO STOP THE VEHICLE UNDER THE CONDITIONS OBSERVED. NO WARNING LIGHTS CAME ON BEFORE, DURING, OR AFTER THE INCIDENT. THE SYMPTOMS MATCH THOSE REPORTED UNDER BULLETIN PIT5361 REGARDING A KNOWN ISSUE WITH FAILURE OF THE BRAKE VACUUM PUMP. I PURCHASED THE TRUCK NEW IN AUGUST 2015. THE TRUCK HAS ABOUT 51,000 MILES ON IT.

BRAKE FAILURE AT LOW SPEED. WHILE SITTING IN STOP AND GO TRAFFIC, THE BRAKE PEDAL REACTS AS IF THE VEHICLE ISN'T RUNNING. PEDAL SEEMS HIGH AND HARD THEN SOFT AND LOW. VEHICLE WILL STOP WITH EXTREME PRESSURE ON PEDAL.

WENT TO GO USE MY BRAKES AND NOTICED THEY GOT REALLY HARD AND ALMOST HIT SOMEONE. I TOWED IT TO THE DEALERSHIP AND THEY SAID IT WAS A FAULTY VACUUM PUMP, BELT, ETC..I HAD ASKED IF THIS WAS RECALLED THEY SAID NO .TOLD ME IT WAS GOING TO BE 1600 TO FIX. I WENT HOME AND DID A LITTLE RESEARCH APPARENTLY THIS IS AN ISSUE. 2015 CHEVY 1500 65K MILES

THE TRUCK AND TRANSMISSION SHIFT VERY HARD, SLIP OR CAN'T FIND ITS HOME. THE PROBLEM IS THE WORST BETWEEN PARK AND REVERSE, AND 1ST AND 2ND GEAR AROUND 20MPH. I HAVE TAKEN IT IN MULTIPLE TIMES TIMES AND TOLD EVERYTHING IS OPERATING TO SPEC. ONE TIME I WAS TOLD THEY WERE WAITING FOR GUIDANCE FROM GM, BUT THEN FORGOT ABOUT THAT, AND SAID EVERYTHING IS FINE.

LOW SPEED BRAKE ISSUE- BRAKING EFFORT INCREASED CONSIDERABLY AND VEHICLE AND CAUSED BECOME DIFFICULT TO STOP. WHILE PARKING VEHICLE IN PRIVATE PARKING LOT THE BRAKE PEDAL BECAME VERY FIRM WITH NO TAKE UP AND TOOK CONSIDERABLE EFFORT TO BRING THE VEHICLE TO A STOP. IMMEDIATELY BROUGHT VEHICLE TO MECHANIC WHO INFORMED ME THAT THE PROBLEM WAS FAILING BRAKE BOOSTER AND THAT IT IS A COMMON DEFECT WITH THIS MAKE MODEL OF VEHICLE. ALSO INFORMED ME THAT THE WHEN THE BOOSTER BEGINS TO FAIL CAN DEPOSIT CONTAMINATES IN THE OIL SYSTEM THAT CAN PREMATURELY DAMAGE THE ENGINE. A INTERNET SEARCH PRODUCED A LONG LIST OF CUSTOMER WITH SIMILAR VEHICLES DESCRIBING THEIR EXPERIENCE OF SIMILAR ISSUES. I CALLED THE LOCAL CHEVY DEALER AND THEY ALSO INFORMED ME THAT IS COMMON ISSUE BUT THERE WERE NO RECALLS OR MANUFACTURE ANNOUNCEMENTS ON THE VEHICLE SO THEY WOULD NOT REIMBURSE FOR THE REPAIR. I CONTACTED GM AND THEY LOGGED MY COMPLAINT GM CASE #[XXX] BUT THEY WOULD BE UNABLE TO OFFER ANY REPAIR ASSISTANCE AT THIS TIME. WILL REPAIR VEHICLE AT MY OWN EXPENSE. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TT

TL* THE CONTACT OWNS A 2015 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT THE BRAKE PEDAL BECAME STUCK WHILE REVERSING OUT OF THE DRIVEWAY. THE CONTACT HAD TO APPLY MORE PRESSURE TO THE BRAKE PEDAL THAN USUAL TO SLOW DOWN THE VEHICLE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE DEALER WAS NOT CONTACTED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE BRAKE BOOSTER NEEDED TO BE REPLACED. THE CONTACT PLANNED TO HAVE THE MECHANIC REPAIR THE VEHICLE THIS WEEK. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND PROVIDED A CASE NUMBER. THE FAILURE MILEAGE WAS 44,000.

THE TRUCK IS INTERMITTENTLY HARD TO STOP, I BELIEVE IT IS LOSING VACUUM. I'VE HAD A MECHANIC LOOK AT THE TRUCK AND THEY CANNOT FIND ANYTHING WRONG. THIS IS INTERMITTENT AND I'M SCARED TO DRIVE THE TRUCK. THIS ONLY SEEMS TO HAPPEN AT LOW RPM. I BELIEVE THIS SHOULD BE INVESTIGATED BECAUSE THE ISSUE COULD CAUSE AN ACCIDENT. I'M A 235 POUND MALE AND I BELIEVE A SMALLER PERSON WOULD HAVE EVEN MORE TROUBLE STOPPING WITH THE SUDDEN LOSS OF VACUUM. I READ IN A FORUM THAT OTHERS ARE HAVING THE SAME ISSUE AND I SHOULD FILE A COMPLAINT. HAD IT NOT BEEN FOR THE ARTICLE THAT MENTIONED THE NHTSA I WOULD HAVE NEVER FILED A COMPLAINT. I HAVE TO THINK THERE ARE OTHERS DEALING WITH THIS ISSUE AND AREN'T SURE WHERE TO TURN OR REPORT THE ISSUE. PLEASE HELP.
