2015 Chevrolet Silverado 1500 complaints

ON 12/15/2018 MY BRAKE VACUUM PUMP WENT OUT. I HAD IT REPLACED AT A DEALERSHIP. TOTAL COST $1506.56. MASTER CYLINDER, BRAKE BOOSTER, AND A CONNECTING PIPE HAD TO BE REPLACED ALSO. APRIL 2019, I RECEIVE A LETTER FROM GM, DESCRIBING THIS ISSUE AND SAYING IF I HAVE LESS THAN 72,000 MILES OR BOUGHT IT NEW WITHIN THE LAST 6 YEARS,WHICHEVER COME FIRST, THEY WILL FIX IT. BRAKES ARE A VERY SERIOUS COMPONENT. THIS PROBLEM DATES BACK TO THE 2014,S. I FEEL GM SHOULD REIMBURSE ME FOR MY REPAIR COST, SINCE THE PROBLEM CAME FROM THEIR PLANT. I HAVE MORE MILES ON MY TRUCK THAN THEY SAY THEY WILL COVER. BRAKES AND THE COMPONENTS ARE THINGS THEY SHOULD COVER. I HAVE INVOICES AND PROOF THAT I PAID THESE EXPENSES. EVERY PERSON PAYS HARD EARNED MONEY FOR A NEW VEHICLE. MANUFACTURERS SHOULD BE REQUIRED TO BACK THEIR VEHICLES. I WAS DRIVING ON A SIDE STREET WHEN THIS PUMP WENT OUT. I HAD ALL I COULD DO TO STOP IT, USING BOTH FEET ON THE BRAKE PEDAL. THANK YOU FOR YOUR TIME.

TL* THE CONTACT OWNS A 2015 CHEVROLET SILVERADO 1500. WHILE DRIVING AT A LOW SPEED, THE BRAKE PEDAL BECAME STIFF AND THE BRAKES FAILED TO RESPOND IN A TIMELY MANNER. THE CONTACT HAD TO DEPRESS THE BRAKE PEDAL SEVERAL TIMES TO STOP THE VEHICLE. THE FAILURE WAS EXPERIENCED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO HEALEY CHEVROLET (5216 NY- ROUTE 17M, NEW HAMPTON, NY 10958, (845) 360-9821) WHERE IT WAS DIAGNOSED THAT THE BRAKE VACUUM PUMP WAS LEAKING OIL. THE VEHICLE WAS REPAIRED AND THE VACUUM PUMP WAS REPLACED. THE MANUFACTURER WAS CONTACTED AND STATED THAT THE VEHICLE DID NOT QUALIFY FOR THE MANUFACTURER'S BRAKE VACUUM PUMP REPLACEMENT BECAUSE THE MILEAGE EXCEEDED 72,000. THE MANUFACTURER PROVIDED CASE NUMBER: 95212761589. THE FAILURE MILEAGE WAS 94,000. *BF *JB

TL* THE CONTACT OWNS A 2015 CHEVROLET SILVERADO 1500. WHILE DRIVING APPROXIMATELY 30 MPH AND APPROACHING A RED LIGHT, THE BRAKE PEDAL WAS DEPRESSED, BUT FELT VERY HARD. THE CONTACT HAD TO PUMP THE BRAKE PEDAL SEVERAL TIMES TO STOP THE VEHICLE. THE CONTACT STATED THAT THE BRAKE FAILURE OCCURRED FOR THE PAST TWO MONTHS ON A DAILY BASIS. THE CONTACT ALSO STATED THAT THE HEADLIGHT ASSEMBLIES WERE FRACTURED AND CAUSED THE HEADLIGHTS TO BE VERY DIM. THE CONTACT DROVE THE VEHICLE TO JUD KUHN CHEVROLET (3740 HWY 9 E, LITTLE RIVER, SC 29566) AND THEY OFFERED TO REPAIR THE HEADLIGHT ASSEMBLIES; HOWEVER, THE CONTACT WOULD HAVE TO PAY HALF OF THE REPAIR COST. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 65,216.

WHEN BRAKING FREQUENTLY IN A PARKING LOT OR AT LOW SPEEDS THE STOPPING POWER GETS WORSE AND ALMOST WILL NOT STOP THE VEHICLE. I HAVE 86,760 MILES ON MY TRUCK CURRENTLY BUT THIS HAS DONE IT SINCE 20,000 MILES AND SINCE THEN OFF AND ON.

WHEN I GO SLOW THE BREAK PEDAL GET SO HARD I CAN STOP

WHEN AT A SLOW ROLLING SPEED BRAKES ARE EXTREMELY HARD TO BRAKE, MAINLY WHEN IN PARKING LOTS OR BACKING MY BOAT IN THE BOAT RAMP ITS EXTREMELY SCARY AND SEEMS LIKE THE TRUCK WONT STOP ROLLING. THIS IS SO UNSAFE AND SCARY. ITS ALMOST LIKE THE BRAKES DONT WORK. BUT IM PRETTY SURE ITS THE VACUUM PUMP BRAKE SYSTEM.

INCREASED BRAKE PEDAL EFFORT, HARD BRAKE PEDAL, AND/OR POTENTIALLY INCREASED STOPPING DISTANCE DUE TO LOW MECHANICAL VACUUM PUMP OUTPUT. CONDITION IS MORE PREVALENT AT LOW SPEED WHEN SOFTLY APPLYING THE BRAKE. DECREASE VACUUM/POWER BRAKE ASSIST OVER TIME, FAILURE TO FOLLOW RECOMMENDED OIL CHANGE INTERVALS COULD CONTRIBUTE TO CONDITIONS. DRIVER'S INFORMATION CENTER (DIC) "SERVICE BRAKE ASSIST" ALERT WILL ACTIVATE 2-5 MINUTES AFTER DROPPING IN VACUUM LEVEL, AND DIAGNOSTIC TROUBLE CODE (DTC) WILL ALSO BE SET. HYDRAULIC BRAKE SYSTEM REMAINS FUNCTIONAL BUT MAY REQUIRE ADDITIONAL PEDAL FORCE.

WHEN TRAVELING IN LOW SPEEDS, USUALLY IN REVERSE, I HAVE TO INCREASE MY BREAK PEDAL EFFORT AND PRESS REALLY HARD TO STOP THE TRUCK. THIS DOES NOT HAPPEN EVERY TIME I DRIVE IT BUT IT DOES HAPPEN OFTEN.

MY TRUCK HAS A STUCK LIFTER

BRAKE VACUUM PUMP FAILED WHICH RESULTED IN DIMINISHED BRAKING PERFORMANCE. THIS WAS VERY DANGEROUS AS WE WERE PULLING A CAMPER WHEN IT HAPPENED. DEALERSHIP REPLACED VACUUM PUMP WHEN VEHICLE WAS AT 78260MILES ALTHOUGH CONDITION STARTED BEFORE THAT. WE RECEIVED A LETTER ABOUT REIMBURSEMENT BUT IT ONLY APPLIES TO 72000 MILES OR 6 YEARS. THE REPAIR COST US OVER $500.

MY VACUUM PUMP ON MY 2015 HIGH COUNTRY SILVERADO IS GOING BAD, IS WHAT THE CHEVY DEALER DIAGNOSED AFTER I EXPLAINED HOW WHEN I REVERSE SPECIALLY IT FEELS LIKE MY BRAKES ARE FAILING AND THEN THE PEDDLE GETS SUPER HARD. THEY SAID ITS NOT NORMAL BUT HOW DO YOU FEEL SAFE IN MY CHEVROLET TRUCK IF MY BRAKES CAN SUDDENLY GO OUT?

TL* THE CONTACT OWNS A 2015 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT THERE WAS FUEL FLOWING AND LEAKING FROM THE DOOR FRAME AREA. THERE WAS AN ABNORMAL ODOR OF FUEL IN AND OUTSIDE THE VEHICLE. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TOWED TO MATT BLATT KIA OF TOMS RIVER (1070 NJ-37, TOMS RIVER, NJ 08755, (732) 281-0000) WHERE IT WAS DIAGNOSED THAT THE FUEL LINES WERE RUSTED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS CONTACTED AND REFERRED THE CONTACT TO THE LOCAL DEALER. THE FAILURE MILEAGE WAS 53,000. *BF CONSUMER STATED HE GIVES PERMISSION FOR NHTSA ON THE FUEL LINE LEAKING GAS.*JB

HEADLIGHTS FLICKERING WHEN ON. WHILE IN MOTION MY STABILITRACK LIGHT ILLUMINATES ALONG WITH THE SEATBELT LIGHT. WHEN USING THE TURN SIGNAL THE RADIO DISPLAY GOES OUT FOR ABOUT A SECOND AND TURNS BACK ON. WHEN BRAKING THE RADIO DISPLAY GOES OFF FOR A SECOND. I GET A LOW BATTERY SIGNAL MAYBE 2 OR 3 TIMES A WEEK, I DRIVE MY TRUCK DAILY. IT HAS 76K MILES. I LOSE POWER STEERING AFTER ABOUT 150 MILE DRIVE. ITS BEEN HAPPENING FOR ABOUT 3-4 MONTHS. 4/22/2019 WAS THE WORST. ALL OF IT HAPPENED YESTERDAY ON A 175 MILE DRIVE

I HAVEN'T USED THE A/C IN MY TRUCK SINCE LAST OCTOBER (2018) APPROXIMATELY. TWO WEEKS AGO WAS THE FIRST TIME I'VE TRIED TO USE MY A/C AND IT IS ONLY BLOWING HOT AIR, AS I WAS DRIVING DOWN THE INTERSTATE. FROM WHAT I'VE RESEARCHED, THIS IS AN KNOWN PROBLEM WITH A LOT OF VEHICLES FROM GM FROM 2014-2017 AND NOTHING IS BEING DONE ABOUT IT.THIS IS NOT OKAY, WHATSOEVER.

IN DECEMBER 2018 WHILE IN A PARKING LOT AT LOW SPEED, BRAKES WERE APPLIED. BRAKE PEDAL WENT ABOUT HALFWAY THEN BECAME "HARD." THERE WAS NO BRAKING POWER AND BRAKES WOULD NOT WORK. THIS WAS ASSOCIATED WITH A "CLICKING" NOISE. WHEN CAR ROLLED TO A STOP I STARTED MOVING AGAIN AND REAPPLIED THE BRAKES. SAME RESULT BOTH IN FORWARD AND REVERSE. THIS HAPPENED AGAIN IN A PARKING LOT ON APRIL 11, 2017. MY VEHICLE CURRENTLY HAS 83,000 MILES. TOOK IT TO A CHEVROLET DEALER AND THEY STATED THE ISSUE WAS THE VACUUM PUMP AND RECOMMENDED REPAIRS ACCORDING TO THEIR PIT5361D. HOWEVER THEY STATED THAT GM RECENTLY PUBLISHED THAT THEY WOULD ONLY WARRANTY THE FIX UP TO 72,000 MILES. I HAVE NOT HAD THE REPAIR COMPLETED YET.

BRAKE FAILURE , WHILE PULLING INTO OR OUT OF A PARKING SPOT , BRAKES LOSE PRESSURE AND BECOME VERY STIFF AND STOP WORKING. THE PEDAL BECOMES QUITE HARD AND WILL NOT WORK CAUSING VEHICLE TO CONTINUE MOVING FORWARD OR REVERSE. ESPECIALLY AT SLOW SPEEDS, I HAVE BARELY MISSED IMPACTING THE CARS ACROSS THE PARKING LOT.

BRAKE ASSIST KEEPS POPPING UP ON INFO SCREEN. THERE'S A DELAY IN BRAKING WHILE PARKING AND WHEN CLIMBING STEEP GRADES IN 4 WHEEL DRIVE.

VACUM PUMP FOR BRAKES WENT OUT. WHEN BACKING UP OR PULLING FORWARD AT SLOW SPEEDS THE BRAKE PEDEL STIFFINS UP AND DOESNT STOP THE VEHICLE.

HAVE BEEN PARKING OR BACKING OUT OF PARKING SPACES AND BRAKE HARDENS AND LOCKS WHILE VEHICLE IS MOVING. HAS ALSO HAPPENED WHILE STUCK IN SLOW TRAFFIC. THIS HAS HAPPENED MULTIPLE TIMES ON DIFFERENT DAYS.

LOSS OF POWER BRAKING WHILE TRAVELING SLOWING AND USING THE BRAKES

THE BRAKES OCCASIONALLY WILL GET HARD WHEN DEPRESSING AT A LOW SPEED AND FAIL TO WORK. THIS USUALLY HAPPENS COMING TO A FINAL STOP IN MY DRIVEWAY THAT IS DOWN A SLOPE AFTER I HAVE ALREADY BEEN USING THE BRAKE TO SLOW DOWN SOME. THE VEHICLE IS BARELY MOVING WHEN IT HAPPENS. IT HAS HAPPENED A COUPLE OF OTHER TIMES GOING DOWN A SLOPE IN OUR SUBDIVISION ENTRANCE APPLYING OCCASIONAL BRAKE PRESSURE AT ABOUT 20 MPH. I HAD IT DIAGNOSED BY THE LOCAL CHEVY DEALER AND THEY SAID THE VACUUM PUMP AND SEAL NEEDS TO BE REPLACED AND THE BRAKE SYSTEM FLUSHED. TOTAL ESTIMATE FOR THE WORK WAS $970 WHICH I DID NOT HAVE DONE. I NOTICED ONLINE THAT OTHERS HAVE HAD THIS SAME ISSUE.

I HAVE BEEN COMPLAINING OF A BRAKING ISSUE SINCE I PURCHASED MY TRUCK IN 2015 AND HAVE HAD THEM INSPECTED AT SEVERAL CHEVY DEALERSHIPS, STONEBRIAR CHEVROLET N FRISCO, HUFFINES CHEVROLET IN LEWISVILLE. WE HAVE MOVED AND I TOOK INTO TODAY AND NOW THAT THE TRUCK IS OUT OF WARRANTY I'M BEING TOLD I HAVE A FAULTY VACUUM PUMP THAT COULD CAUSE MY BRAKES TO FAIL. THE DEALER, PETERS CHEVROLET IN LONGVIEW, ALSO STATES UNFORUNTELY HE CANNOT SEE MY SERVICE RECORDS TO CONFIRM THE PREVIOUS BRAKE CHECKS WHICH IS RIDICULOUS. THIS IS A KNOWN ISSUE AND GM IS TAKING NO ACCOUNTABILITY IN THIS AND DEMANDING A CHANGE OF $600 TO REPLACE. PLEASE HELP.

THERE IS A FAULTY AC CONDENSER COMPONENT THAT LEAKS. THIS CAUSES ALL THE FREON TO BE SPILLED OUT AND MAKE THE AC BLOW HOT AIR.

LOSS OF POWER BRAKES AT LOW SPEED WHEN BACKING INTO PARKING SPOT. 4 OCCURRENCES SINCE OCTOBER 2018 UNDER EXACT SAME CIRCUMSTANCES, CHECKED BY DEALER, NO WORK DONE BUT TAC CASE OPENED.

THE PAINT ON THIS TRUCK HAS BEGUN TO PEEL IN A COUPLE SPOTS. GM ISN'T WILLING TO FULLY COVER THIS AS THEY SAY IT IS OUT OF WARRANTY. A 4 YEAR OLD VEHICLE SHOULDN'T HAVE PAINT ISSUES LIKE THIS, ESPECIALLY WHEN IT IS A COMMON OCCURRENCE WITH THIS MODEL YEAR.

BREAK VACUUM PUMP BREAKS GET HARD AT LOW SPEED MAKING THE THE VEHICLE HARD TO BREAK WHEN MAKING A STOP OR IN AN EMERGENCY STOP AND WHEN TRYING TO SLOW DOWN

A/C STOPPED COOLING. STILL BLOWING, BUT NOT COOLING. WAY TO NEW OF A TRUCK TO HAVE THIS ISSUE WITH 100 TEMPS COMING SOON.

2015 CHEVY SILVERADO. CONSUMER WRITES IN REGARDS TO REAR WINDOW SHATTERING WHILE DRIVING. *LD *TR

WHILE DRIVING SLOW AND MAKING A HARD LEFT TURN EVERYTHING FLASHES OFF 0N DASH ,THEN ON, ON DASH,BUT ENGINE SHUTS OFF CAUSING STEERING AND BRAKING SAFETY CONCERNS,THIS HAS HAPPENED THREE TIMES IN LAST TWO WEEK TOOK IT TO DEALERSHIP THEY COULDN'T

TRANSMISSION EXPERIENCES A SHUDDER THAT CYCLES EVERY 3 SECONDS. THE TORQUE CONVERTER HAD BEEN REPLACED BUT AFTER 45000 MILES IT HAS RETURNED. DEALER HAS RECOMMENDED A NEW TYPE OF TRANSMISSION FLUID REPLACEMENT. ALSO HAD A AFM LIFTER THAT COLLAPSED AND WAS REPLACED.

WHEN BACKING UP I APPLIED THE BRAKES AND THE PEDAL WAS EXTREMELY STIFF BARELY ABLE TO STOP.

TRANSMISSION ALWAYS SHIFTED HARD AND FINALLY STOPPED SHIFTING AT ALL WHILE IN MOTION (BACKING OUT OF OUR DRIVEWAY). DESPITE TAKING IT A CHEVY DEALERSHIP FOR 3 YEARS FOR MAINTENANCE, WE WERE NEVER TOLD THEIR WAS A KNOWN ISSUE. WHEN THE TRANSMISSION FAILED, WE TOOK IT BACK TO THE CHEVY DEALERSHIP AND ONLY WHEN WE TOOK IT TO A TRANSMISSION SHOP TO GET A SECOND OPINION WERE WE TOLD THIS WAS A KNOWN FACTORY DEFECT ON SEVERAL GM MODELS. WE ENDED UP HAVING TO HAVE THE TRANSMISSION REBUILT ALONG WITH THE REAR END TO THE TUNE OF OVER $5,000. LEMON LAW DOES NOT HOLD UP BECAUSE WE DID NOT HAVE ANY WORK DONE UNDER THE WARRANTY (WHICH ONLY COVERED THE FIRST YEAR).

WHILE BACKING INTO PAVED BOAT RAMP AT 1.5 TO 2 MPH BRAKE PEDAL BECAME VERY HARD AND HAD TO PRESS PEDAL AS HARD AS I COULD IN ORDER TO STOP TRUCK. "TRUCK WAS ON LEVEL GROUND AND I WAS TURNING STEERING WHEEL SLOWLY". I PULLED OUT OF RAMP AND PROBLEM REPEATED WHEN BRAKE PEDAL PRESSURE WAS APPLIED AND REMOVED AND THEN REAPPLIED. PROBLEM CONTINUED TO REOCCUR AFTER TRAILER REMOVED FROM TRUCK AND BRAKE PEDAL PRESSURE WAS APPLIED AND REMOVED THEM REAPPLIED. TRUCK WAS LOOKED AT BY DYER CHEVROLET THE NEXT DAY. CHEVROLET IS AWARE OF ISSUE AS TECH HEARD MY DESCRIPTION AND HE STATED THERE WAS A BULLETIN FROM GM ON IT BUT IT WAS NOT RECALLED. AFTER RECEIVING ESTIMATE LATER THAT DAY FROM CHEVROLET I DECIDED TO TAKE TRUCK TO ANOTHER REPAIR FACILITY THAT ESTIMATED REPAIR $500 CHEAPER THAN CHEVROLET DEALER. REPAIRS WERE MADE FOLLOWING THE GM BULLETIN AND USING GM PARTS FROM THE CHEVY DEALER FOR $1139 AS OPPOSED TO DYER CHEVROLET WANTING $1662 FOR A ISSUE THAT NEEDS TO BE RECALLED. A QUICK INTERNET SEARCH INDICATES THAT MANY OTHERS ARE AFFECTED BY THE ISSUE AS WELL. IT IS MY HOPE THAT YOU MAY BE ABLE TO HELP AS I AM SURE THIS WILL OCCUR AGAIN AS GM HAS NOT CHANGED ANYTHING THEY HAVE MERELY CHARGED THE CUSTOMER TO PUT A BANDAID ON A PROBLEM THEY ENGINEERED. THE MECHANIC THAT ULTIMATELY REPAIRED TRUCK STATED GM KNOWS THEY HAVE PROBLEM AS THEY ONLY USED THAT BOOSTER PUMP ON 2015. THERE IS NO WAY A 50000 MILE TRUCK SHOULD HAVE THIS ISSUE. PLEASE SEE ATTACHED DOCUMENTS FROM CHEVROLET DEALER THAT DES

BRAKES STOP WORKING AT LOW SPEEDS OR WHEN REVERSING. FEEL LIKE THEY GET COMPLETELY STIFF AT LOW SPEEDS, AND DONT WORK AGAIN UNTIL I INCREASE THE AMPS. I HAVE READ THAT IT IS AN ISSUE WITH THE VACUUM PUMP. GETTING LOOKED AT TODAY. TRUCK HAS 77K MILES ON IT.

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

WHILE DRIVING IN STOP AND GO TRAFFIC THE VACUUM POWER ASSIST FOR THE BRAKES FAILED MULTIPLE TIMES MAKING IT MUCH MORE DIFFICULT TO BRAKE AND STOP THE VEHICLE BEFORE COLLIDING WITH THE CAR IN FRONT OF ME. THIS HAPPENED WHILE DRIVING ON CITY STREETS. A VEHICLE WARNING MESSAGE APPEARED IN THE DRIVERS INFORMATION DISPLAY STATING SERVICE BRAKE SYSTEM. THE MESSAGE WENT AWAY AFTER SUSTAINED CONTINUOUS DRIVING WITHOUT BRAKING WHEN THE VACUUM SYSTEM WAS ABLE TO RECOVER.

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

AIR CONDITIONER NOT WORKING IS HAVE A LICKS

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.

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.

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

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.

BRAKES SUDDENLY REQUIRED MUCH MORE EFFORT TO WORK. HAPPENS FREQUENTLY WHEN APPLYING BRAKES AT LOW SPEEDS, AND OCCASIONALLY WHEN APPLIED INTERMITTENTLY WHILE SLOWING FROM 50-80MPH. EXAMPLES OF WHEN THIS FREQUENTLY OCCURS ARE: ENTERING PARKING SPACES, STOP AND GO TRAFFIC, APPROACHING TOLL BOOTHS ON HIGHWAYS, DESCENDING HILLS, AND ANY SITUATION WHERE BRAKES ARE APPLIED AND RELEASED REPEATEDLY OVER A SHORT PERIOD OF TIME. CONDITION CAN BE VERY DANGEROUS AND CAUSE ACCIDENTS. I HAVE NEEDED TO STAND ON BRAKES WHEN STOPPING IN MANY OCCASIONS TO AVOID ACCIDENTS. LATELY THE CONDITION HAD WORSENED AND I DID NOT FEEL SAFE DRIVING THE VEHICLE. UPON RESEARCHING THE ISSUE I FOUND MANY SIMILAR COMPLAINTS FROM OWNERS AND SURVIVE BULLETINS FROM GM THAT INCLUDE A LARGE AMOUNT OF AFFECTED VEHICLES. THIS SHOULD BE A FORCED SAFETY RECALL.

DRIVING NEWLY PURCHASED 2015 CHEVY SILVERADO 1500 AT 35-45 MPH ON FREEWAY (WHICH HAS A 65 MPH SPEED LIMIT). TRAFFIC AHEAD WAS SLOWING DOWN, AND THE BRAKES WERE PRESSED, SPEED WAS REDUCED, BUT WHEN THE CARS IN FRONT (WITH AT LEAST 5 CAR LENGTHS OF SPACE ) SUDDENLY STOPPED, AND I SLAMMED THE BRAKES, THE BRAKES FAILED. I TRIED AND TRIED PRESSING THE BRAKES, BUT THE TRUCK DIDN'T STOP, AND I REAR-ENDED THE VEHICLE IN FRONT OF ME, WHICH ENDED UP REARING THE VEHICLE AHEAD OF IT, AND SO FORTH. DUE TO THE BRAKES NOT RESPONDING, I WAS UNABLE TO STOP LIKE THE REST OF TRAFFIC, AND THUS, CAUSED AN ACCIDENT. (NOTE: THE WEATHER AND ROAD CONDITIONS WERE FINE, NOT WENT ROAD, AS STATED ON POLICE REPORT.)

BRAKING ASSIST SERVICE WARNING MESSAGE APPEARED ON SCREEN. NOTICED BRAKING ASSIST IS NOT WORKING AT LOW SPEED AND IDLE. REQUIRES SIGNIFICANT FOOT PRESSURE TO HAVE BRAKES WORK. NO ACCIDENT YET.

I HAVE A 2015 SILVERADO 1500 5.3 WITH ABOUT 90K MILES. WHILE I WAS PARALLEL PARKING, AFTER THE 2ND PUMP, I REALIZED THE TRUCK WASNT STOPPING. I HAD TO USE BOTH LEGS TO MAKE IT STOP BEFORE HITTING THE CAR IN THE BACK OF ME AND ALMOST CRUSHING A PEDESTRIAN. MY BRAKE PADS AND ROTORS ARE FINE. I DO HEAR AN ABNORMAL NOISE COMING FROM THE ENGINE AREA AT ALL TIMES. KINDA LIKE A BAD PULLEY BEARING OR SOMETHING. NOTICED IT THE DAY THE TRUCK STARTED ACTING UP. I LOOKED ONLINE ON MUTIPLE WEBSITES AND UNDERSTAND THIS IS A COMMON PROBLEM WITH THE VACUUM PUMP, BRAKE BOOSTER AND MASTER CYLINDER. THIS SHOULD BE A SAFETY RECALL.
