2015 Chevrolet Malibu Brakes Problems

The vacuum boost pump failed suddenly leaving the vehicle with no brakes and potentially causing catastrophic engine damage.

CAR WAS INITIALLY BROUGHT TO INDEPENDENT SERVICE CENTER IN SAVANNAH, GA. THEY WERE ABLE TO REPLICATE THE PROBLEM WITH THE BRAKING SYSTEM, BUT COULD NOT DETERMINE THE ROOT CAUSE. SPECIFICALLY, THE BRAKES FAIL WHEN THE CAR IS PLACED IN REVERSE. IT MAY BE TEMPERATURE SENSITIVE AS IT IS EXPERIENCED WHEN THE CAR IS STARTING UP - TYPICALLY IN THE MORNING. THEY SOUGHT HELP FROM VADEN CHEVROLET IN SAVANNAH, GA. THE CAR WAS IN THEIR POSSESSION FOR 1+ WEEKS AND THEY DID NOT FIND A PROBLEM WITH THE BREAKING SYSTEM. THE CAR WAS THEN RETURNED TO THE INDEPENDENT SERVICE CENTER WHERE THEY CONTINUE TO STUDY THE PROBLEM. WHEN THE CAR WAS RETURNED TO INDEPENDENT SERVICE CENTER AND VADEN FAILED TO ACKNOWLEDGE THIS SAFETY ISSUE, I CONTACT GENERAL MOTORS (1-866-636-2273) TO REPORT THIS SAFETY ISSUE DIRECTLY. THE INDIVIDUAL MY CASE WAS ASSIGNED TO, "[XXX]", DID NOT FOLLOW UP ON ACTION ITEMS AND WHEN I TRIED TO RETURN HER CALLS, HER VOICEMAIL BOX WAS FULL. I ASKED FOR THIS CASE TO BE ESCALATED TODAY (2/5/2020), BUT SHE INDICATED SHE WAS AT THE TOP - NO ONE TO ESCALATE ISSUE TO. WHEN I ASKED IF SHE REPORTED DIRECTLY TO GM'S CEO, [XXX] , SHE STATED SHE DID NOT KNOW WHO THAT WAS. I HAVE BEEN WITHOUT A CAR FOR QUITE SOMETIME NOW (MONTHS) AND WOULD LIKE THIS SAFETY ISSUE TO BE ACKNOWLEDGED BY GM AS IT WAS ACKNOWLEDGED BY MY INDEPENDENT REPAIR CENTER. I AM TRYING TO PREVENT A SERIOUS PROBLEM (BRAKES FAILING WHILE CAR IS IN USE), BUT GM IS NOT LISTENING. I WILL NOT DRIVE MY CAR UNTIL IT IS ADDRESSED, BUT IT'S QUITE POSSIBLE THIS PROBLEM EXISTS IN OTHER 2015 CHEVY MALIBU'S WHERE PERHAPS THE DRIVERS AREN'T YET AWARE OR DON'T UNDERSTAND THE POTENTIAL SERIOUSNESS OF THIS ISSUE WITH AN UNADDRESSED, UNKNOWN ROOT CAUSE. I'M GRATEFUL FOR ANY ASSISTANCE. THANK YOU. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THE ABS BRAKE LIGHT COMES ON SEVERAL TIMES. MUST TURN ENGINE OFF AND RESTART TO RESET. USUALLY THE ABS LIGHT COMES ON WHEN BACKING UP. SOME TIMES WHEN DRIVING.

CAR WOULD NOT BRAKE CAUSING A COLLISION BEFORE THAT AUTO STOP AND PROBLEMS WITH BOTH BATTERIES

TL* THE CONTACT OWNS A 2015 CHEVROLET MALIBU. WHILE DRIVING APPROXIMATELY 55 MPH, THE BRAKES MADE A RUBBING NOISE WHEN THE BRAKE PEDAL WAS DEPRESSED. THERE WAS NO WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO REFERRED THE CONTACT TO SHOTTENKIRK CHEVROLET (5031 AVENUE O, FORT MADISON, IA 52627, 319-248-8866). THE DEALER DIAGNOSED AND REPAIRED THE VEHICLE BY REPLACING ALL THE BRAKE CALIPERS, PADS, AND ROTORS. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 29,000.

STABILIZER TRACKING AND ABS LIGHT JUST CAME ON MY CAR YESTERDAY FOR NO REASON, I DON'T SENT ANY DIFFERENT IN HOW ITS BREAKING. I HAVE ABOUT 58000 MILES ON IT, THIS ALL SHOW UP COMING HOME AFTER DRIVING 20 MILES.
