2015 CHEVROLET SILVERADO 1500 Complaints

ENGINE POWER REDUCED ERROR POPS UP AND AND BASICALLY KILLS ANY ABILITY TO ACCELERATE. THIS HAS HAPPENED MULTIPLE TIMES INCLUDING TWICE AT INTERSTATE SPEED AND FEW TIMES UNDER 45MPH. IF THIS WERE TO HAPPEN WHILE CROSSING AN INTERSECTION, RAILROAD, ETC., THE VEHICLE WOULD BE A SITTING DUCK.

I UNERSTAND THAT YOU ARE ALREADY INVESTIGATING THE BRAKING BRAKING PROBLEM AT SLOW SPEEDS , I HAVE BEEN EXPERIENCING THE SAME PROBLEM FOR SOME TIME , CAN YOU PLEASE ADD ME TO YOUR COMPLAINT LIST , AND KEEP ME INFORMED OF ANY RESULTS , THANKS (XXXXX) PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

VACUUM PUMP FOR BRAKE SYSTEM AND HOSE/TUBE THAT CONNECTS TO THE PUMP HAD TO BE REPLACED AFTER I LOST BRAKES COMPLETELY WHILE DRIVING THE VEHICLE WITH MY TWO YEAR OLD DAUGHTER IN THE BACK SEAT!! THE VEHICLE HAD TO BE TOWED TO AUTO REPAIR SHOP. MILEAGE WAS AT 55,096. THIS HAPPENED WHILE IN A DRIVE THRU LINE AT CHIC FILA. BRAKES GOT VERY HARD AND I JUST KEPT ROLLING INTO VEHICLE IN FRONT TO ME. I STOPPED ROLLING JUST SHORT OF HITTING THE VEHICLE. I SLOWLY WENT THROUGH THE LINE TO PARK THE VEHICLE IN THE PARKING LOT AND THE BRAKES WERE COMPLETELY ROCK HARD THE ENTIRE TIME. I HAD TO SIMPLY ROLL TO GET WHERE I NEEDED TO PARK SLOWLY.

WHENEVR I BACK THE TRUCK UP AT SLOW SPEEDS, THE BRAKES TEMPORARILY FAIL FOR APPROXIMATELY 1-3 FEET. COMING TO A STOP AT SLOW SPEEDS CAN ALSO CAUSE THE TRUCK TO TAKE EXTRA DISTANCE TO STOP. I HAVE CHANGED TO NEW BRAKE PADS, TURNED THE ROTORS, AND PURCHASED NEW TIRES. THE TRUCK BOUNCES SEVERELY WHEN TRAVELING AT SPEEDS OVER 50 MPH ON CONCRETE ROADS. ONLY ON CONCRETE. ASPHALT HAS NORMAL RIDE AS SOON AS THE ROAD TRANSITIONS THEN THE TRUCK BOUNCES.

PURCHASED USED 2015 SILVERADO LTZ WITH 87K MILES ON 12/1/2018 FROM DEALER. ON 12/2/2018 WHILE BACKING OUT OF PARKING SPACE FOR FIRST TIME, BRAKE PEDAL WOULD ONLY MOVE 1/4 INCH WITH GREAT EFFORT (80-100LBS EFFORT), AND ONLY APPLIED ENOUGH BRAKING FORCE TO STOP TRUCK MOVING 2 MPH OVER 5 OR 6 FEET. WAS ABLE TO IMMEDIATELY RECREATE PROBLEM MOVING FORWARD WHILE UNDER 5-6MPH, EACH TIME TAKING ROUGHLY 10-12 FEET TO STOP WITH GREAT BRAKING EFFORT. PROBLEM OCCURRED AGAIN 12/3 AFTER A SHORT TRIP (3 MILES, 40MPH) WHILE SLOWLY BACKING INTO PARKING SPACE. PUT TRUCK IN DRIVE AND THE BRAKE PROBLEM PERSISTED. BACKED UP AGAIN, PROBLEM PERSISTED. MAXIMUM BRAKING FORCE WOULD NOT STOP TRUCK FROM ROLLING DOWN 7% GRADE FROM DEAD STOP. MAXIMUM BRAKING FORCE WILL ABSOLUTELY NOT STOP TRUCK IN STOP-AND-GO TRAFFIC WHEN THIS PROBLEM OCCURS AGAIN. **** MUST DRIVE IN FAR RIGHT OR LEFT LANE TO ENSURE SPACE TO SWERVE INTO WHEN BRAKES FAIL TO AVOID COLLISION. **** EXTREME SAFETY HAZARD - WILL CAUSE ACCIDENTS, INJURIES & PROPERTY DAMAGE. THIS NEEDS TO BE A RECALL ASAP.

I WAS PULLING INTO A PARKING SPOT AND WHEN PRESSING THE BRAKE PEDAL TO STOP IT GOT REALLY HARD, HAD NO BRAKE PRESSURE TO STOP, THANKFULLY I HAD NO CONCRETE BARRIERS OR LIGHT POSTS IN FRONT OF ME TO CAUSE ANY DAMAGE JUST GRASS ON A HILL TO HELP ME STOP. SECOND TIME THIS HAPPENED I WAS BACKING UP TO MY GARAGE THAT WAS ON A SLIGHT HILL AND THE BRAKES GOT HARD BUT I WAS ABLE TO STOP BY PUTTING THE TRUCK IN PARK AND USING MY EMERGENCY BRAKE. THIRD TIME I WAS DRIVING DOWN THE HIGHWAY GOING APPROXIMATELY 65MPH AS I WAS SLOWING DOWN TO GET OFF OF AN EXIT I NOTICED MY BRAKE STARTED TO GET HARD THANK GOODNESS I HAVE A TOW HAUL BOTTON AND I USED THAT TO HELP ME SLOW DOWN TO GET OFF THE EXIT. EVERYTIME MY BRAKES HAVE GOTTEN HARD IS WHEN I HAVE TO BACK DOWN A HILL, PULL DOWN A HILL, PARK IN A PARKING SPOT OR HAVE TO PRESS THE BRAKES CONSTANTLY TO SLOW DOWN.

BREAKING SYSTEM VACUUM PUMP FAILURE. COMMON AND KNOWN PROBLEM. BRAKES SPORADICALLY REQUIRE SUBSTANTIALLY MORE EFFORT TO SLOW VEHICLE AND INCREASES BREAKING DISTANCE SIGNIFICANT WITH NO WARNING. INCREASES LIKELIHOOD OF CRASHES. MINE FAILED WHILE DRIVING 30 MILES AN HOUR ON AN EXIT RAMP ALMOST CAUSING A COLLISION. GM REFUSES TO COVER THIS UNDER WARRANTY AND DESPITE KNOWING THAT THIS IS A COMMON PROBLEM, HAS NOT ISSUED A RECALL.

BRAKE PEDDLE RANDOMLY BECOMES HARD TO PUSH AND WILL NOT STOP THE VEHICLE AFTER OTHERWISE NORMAL FUNCTIONING. THIS OCCURS GENERALLY AT LOW SPEEDS IN FORWARD AND REVERSE. THIS HAS OCCURRED ON NUMEROUS OCCASSIONS BUT RANDOMLY

BRAKE PEDAL IN THE TRUCK WILL OCCASIONALLY GO TO THE FLOOR WHEN THE TRUCK IS IN REVERSE. THE PROBLEM SEEMS TO HAPPEN MORE WHEN BACKING A BOAT TRAILER DOWN A RAMP AT A BOAT LAUNCH WHERE THE TRUCK IS AT AN ANGLE. HAVE LOST BRAKES MULTIPLE TIMES WHEN DOING THAT. FLUID IS FULL IN THE RESERVOIR AND THE MECHANICAL PORTION (BRAKE PADS, ROTORS, CALIPERS) CHECKED OUT AS FINE.

WAS PULLING INTO A PARKING STALL SLOWLY AND TRUCK WOULD NOT STOP WHEN APPLYING THE BRAKE PEDAL. BRAKE PEDAL WAS VERY HARD TO PRESS AND USED BOTH FEET TO PRESS ON THE PEDAL TO EVENTUALLY MAKE THE TRUCK COME TO A STOP. CAUSED A MINOR (COSMETIC) SCRAPE ON PASSENGER SIDE FRONT BUMPER (SCRAPED CONCRETE WALL) DUE TO THE INABILITY TO STOP WHEN BRAKE WERE BEING PRESSED.
