2011 GMC Yukon Brakes Problems

The contact owns a 2011 GMC Yukon. The contact stated that while driving at 60-65 MPH, the check engine warning light, the ABS warning light, the emergency parking brake warning light, the stability tract warning light, the warning indicator “Service Brake System” and other unknown warning lights illuminated. The brake pedal was depressed but felt rigid and failed to respond. The contact depressed the brake pedal with more pressure, but it hesitated to respond, causing 40 feet in stopping distance delay. The contact continued to drive the vehicle. The vehicle was taken to the dealer where it was diagnosed that the EBCM module, the BPCM module and the valve ABS unit needed to be replaced. The contact stated that the vehicle was repaired; however, the failure had been reoccurring while driving. The manufacturer was notified of the failure and referred the contact to the dealer for diagnostic testing. The vehicle was not repaired. The failure mileage was approximately 131,814.

ABS BRAKE PROBLEM. REOCCURRING ENGINE PROBLEMS SUCH AS MISFIRE, LOW CYLINDER COMPRESSION, AFM LIFTERS, CAMSHAFT, FUEL MIX AND BRAKE SWITCH CAUSES CHECK ENGINE LIGHT TO COME ON. THIS CAUSES STABILITRAK AND TRACTION CONTROL TO BE TURNED OFF. DISCUSSIONS WITH SEVERAL MECHANICS INDICATED A NEW ENGINE WOULD BE THE ONLY WAY TO FIX THIS PROBLEM. EVEN WITH A NEW ENGINE, THE PROBLEM PERSISTS. THE CHECK ENGINE LIGHT CONTINUES TO BE "ON" AND STABILITRAK AND TRACTION CONTROL CONTINUE TO GO ON AND OFF, AND LIVING IN MI IT IS CONCERNING ME THAT I MAY LOSE THESE BRAKING FUNCTIONS WHEN I NEED THEM. GMC HAS OFFERED NO SOLUTIONS. MANY, MANY FORUM DISCUSSIONS ON THE WEB INDICATE OWNERS SUCH AS ME SHOULD CREATE A CLASS-ACTION LAWSUIT, AS THERE DOES NOT APPEAR TO BE A SOLUTION TO THIS PROBLEM. THE STABILITRAK AND TRACTION CONTROL GOES ON AND OFF AS I AM DRIVING, TYPICALLY ON A HIGHWAY.

I HAVE A 2011 YUKON HYBRID 2WD. ON AUGUST 234D, 2014 MY (XXX) YEAR OLD SON AND I WERE RUNNING ERRANDS WHILE EN ROUTE TO HIS BIRTHDAY PARTY. AT OUR FIRST DESTINATION HE NOTICED SOME FLUID LEAKING FROM UNDER THE YUKON AND SAID HE HEARD A HISSING SOUND. I THOUGHT IT WAS JUST CONDENSATION AND CONTINUED ON. WHEN EXITING THE VEHICLE AT OUR SECOND DESTINATION I NOTICED A LOT OF FLUID TRAILING WHERE I HAD JUST DRIVEN THE YUKON. UPON EXITING THE PARKING LOT THE BRAKES TURNED TO MUSH (THE PEDAL WENT ALL THE WAY TO THE FLOOR WITH NO RESISTANCE) AND I HAD NO BRAKING CAPABILITIES. I PULLED OFF INTO A PARKING SPACE AND PUT THE CAR IN PARK. WHEN IT WAS TAKEN TO GMC ,THE MECHANIC FOUND THE BRAKE LINE TO BE BROKEN AND WE HAD TO COVER THE FULL COST FOR THE REPAIR. ON MAY 29TH 2015 A SIMILAR INCIDENT OCCURRED. I WAS DRIVING THE YUKON TO DROP MY CHILDREN OFF AT SCHOOL AND UPON APPROACHING THE DROP-OFF ZONE I PUSHED ON THE BRAKE TO SLOW DOWN AND I LOST ALL BRAKING CAPABILITIES AS THE BRAKE PEDAL WENT TO THE FLOOR WITH NO RESISTANCE. THE STABILITRACK MAINTENANCE LIGHT CAME ON AFTER. IN BOTH INCIDENTS, THERE WAS NO WARNING. I NO LONGER WANT TO BE AN OWNER OF A GMC YUKON AS I FEAR FOR THE LIVES OF MY CHILDREN WHEN THEY ARE IN THE VEHICLE.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).
