2015 CHEVROLET SILVERADO 1500 Complaints

BRAKE PEDAL BECOMES VERY HARD AND BRAKES INEFFECTIVE IF THE PEDAL IS PUSHED AND RELEASED AT IDLE. BRAKE DO NOT START WORKING PROPERLY AGAIN UNTIL THE ACCELERATOR HAS BEEN PRESSED. "SERVICE BRAKE ASSIST" MESSAGE IS DISPLAYED ON THE DIAGNOSTICS SCREEN. DEFINITELY A PROBLEM WITH THE VACUUM PUMP.

AT LOW SPEEDS MY BRAKES ARE VERY HARD TO PRESS. THE PEDAL GETS REALLY TIGHT AND WILL NOT PRESS DOWN. THE LONGER YOU TRY TO PRESS THE TIGHTER THEY GET. THE TRUCK WILL BARELY STOP BEFORE I ALMOST HIT SOMETHING. DOES NOT DO IT EVERY TIME, BUT IT SEEMS TO BE MORE FREQUENTLY. IT SEEMS TO HAPPEN WHEN I GO FROM A STOP, THEN ACCELERATE SLOWLY AND THEN TRY TO SLOW DOWN TO A STOP (EX. WHEN PARKING).

AT LOW SPEEDS I HAVE NO BREAKS AND THE PEDAL IS ROCK HARD. ZERO TO 1/4' OF MOVEMENT AND THE TRUCK WILL NOT STOP. I NEARLY HIT SOMEONE.

WHILE BACKING UP WHEN BRAKES ARE APPLIED THE PEDAL HAS VERY LITTLE TRAVEL AND IS HARD TO PUSH DOWN CAUSING VEHICLE TO CONTINUE BACKING WITH LITTLE STOPPING POWER OR EFFECT. THIS TAKES EFFECT ONLY WHEN BACKING AFTER RESTARTING VEHICLE. SYSTEM CHECKED AT FIRESTONE TIRE CENTER AND RESULT INDICATED BRAKE VACUUM POWER WAS NOT WORKING PROPERLY. THIS OCCURS ALMOST DAILY WHEN BACKING UP.

HAVING ISSUES WITH BRAKING AT SLOW SPEEDS, SPECIFICALLY DURING BACKING UP. WHEN I TOOK MY TRUCK INTO THE DEALER FOR ROUTINE OIL CHANGE I HAD THEM LOOK AT THE BRAKING PROBLEM AND WAS TOLD MY BRAKE VACUUM PUMP IS GOING BAD. I SAW AN ARTICLE ABOUT THIS SAME ISSUE BEING UNDER INVESTIGATION FOR POSSIBLE RECALL AND WANTED TO MAKE SURE MY VOICE WAS HEARD.

BRAKE PEDAL BECOMES UNRESPONSIVE AND SOFT AT TIMES, AND OTHER TIMES FEELS LIKE THE BRAKES ARE NOT RELEASING ALL THE WAY MAKING IT PULL LEFT/RIGHT RANDOMLY AND VERY HARD TO CONTROL. OCCASIONALLY THE ABS ACTIVATES WHILE NOT MOVING/PARKED JUST BY BY HOLDING BRAKE PEDAL. ALSO FOUND OIL OF SOME KIND IN BRAKE FLUID DURING ROUTINE FLUSH. VACUUM PUMP MAKES QUITE A BIT OF NOISE.

I WAS COMING OFF A HILL AND TRYING TO BRAKE BEFORE MAKING A TURN ONTO ANOTHER ROAD. THE BRAKE PEDAL WOULD NOT DEPRESS, FELT VERY HARD AND I WAS UNABLE TO STOP THE VEHICLE. I TOOK THE TRUCK TO A GARAGE AND WAS TOLD IT WAS A FAULT IN THE BRAKE VACUUM BOOSTER AND MASTER CYLINDER. I WILL ATTACH THE INVOICE FOR THE PARTS. THE TRUCK IS STILL GETTING FIXED AND DO NOT HAVE AN INVOICE FOR LABOR YET.

WHILE BACKING UP FROM DRIVE WAY TRIED BRAKING TO STOP AND TRUCK CONTINUED TO TRAVEL ALMOST HITTING A VEHICLE THAT WAS PARKED ON THE STREET. THE NEXT DAY BEFORE TAKING THE TRUCK TO THE DEALER TO HAVE IT INSPECTED MADE A STOP AT THE GAS STATION AND AGAIN THE TRUCK WOULD NOT STOP. DEALER DIAGNOSE BAD VACUUM PUMP AND OIL IN BRAKE BOOSTER AND LINES ,ALL NEEDED TO BE REPLACED COSTING OVER $1,300 DOLLARS.

DURING STOP AND GO TRAFFIC OR REPEATED BRAKING APPLICATIONS MY TRUCK LOSES BRAKING POWER. SEEMS TO BE A VACUUM ISSUE. ALMOST HAD A COLLISION IN A PARKING DECK.

I'VE NOTICED A BIG DECREES IN BREAKING PERFORMANCE IN THE PAST MONTH DOUBLING THE DISTANCE IT TAKES TO COMPLETELY STOP AND IT'S ALMOST CAUSED ME TO REAR END A FEW PEOPLE.
