2005 GMC Yukon Denali Xl Brakes Problems

STARTED CAR IN THE MORNING TO GO TO WORK. AS I DO EVERY DAY. FOOT ON BRAKE AS USUAL, SHIFT TO DRIVE, TO BEGIN A TURN IN MY DRIVEWAY, IN MAKING THE LEFT TURN, WHICH IS A DOWNWARD GRADE, APPLIED BRAKE, WHICH WENT TO FLOOR. NO RESISTANCE WHATSOEVER, COMPLETE FAILURE OF BRAKES. KEPT FOOT ON BRAKE AND STEERED UP THE GRADE, THEN PUT CAR INTO PARK. GOT OUT, OPENED HOOD. CHECKED MASTER CYLINDER- NO FLUID VISIBLE AT USUAL LINE. CHECKED UNDER VEHICLE, BRAKE FLUID TRAILING ON DRIVEWAY UNDER PATH OF VEHICLE, AND SLOW DRIP FROM UNDER FORWARD FRONT DRIVER SIDE . BRAKE LINES AND CONNECTOR COMPLETELY CORRODED AND RUSTED. HAD I BEEN ON THE ROAD I WOULD HAVE BEEN UNABLE TO STOP, VEHICLE IS DRIVEN BY MY SON AS WELL. OUR LIVES AND THOSE OF OTHERS IN THE VEHICLE AS WELL AS OTHERS THAT MEAD BEEN IN OUR PATH WERE CLEARLY IN DANGER. THIS PROBLEM SHOULD NOT OCCUR, AND IS COMPLETELY UNACCEPTABLE.

WAS DRIVING ABOUT 30MPH AND HIT THE BRAKE PEDAL, THE BRAKE PEDAL WENT TO THE FLOOR AND WE RAN INTO A TRAILER. THE BRAKE LINES WERE RUSTED SO BAD THAT THEY BUSTED, AND CAUSED THE BRAKE FLUID TO LEAK OUT. THE ESTIMATE TO REPAIR THE BRAKE LINES ALONE IS $2800. *TR

(3-17-2015) I WAS DRIVING MY 2005 GMC DENALI XL, (WITH UNDER 35000 MILES) THE BRAKE LIGHT COMES ON, WHEN I GO TO PULL OVER, I REALIZE MY BRAKE PEDAL BOTTOMS OUT, I GET IT TO A GMC DEALER, THEY TELL ME MY BRAKE LINES ARE FAULTY DO TO BAD UNDERCARRIAGE CORROSION AND RUST, AND INFORM ME THAT IT MAY TAKE THOUSANDS OF DOLLARS JUST TO CORRECT THE BRAKE LINES, AND THAT OTHER PARTS OR SYSTEMS MAY ALSO FAIL....THEY ALSO SAY IT'S NOT WORTH REPAIRING. THE VEHICLE WAS IN MARYLAND UP UNTIL MAY 2014, WHEN I RELOCATED TO FLORIDA, THE VEHICLE WAS NOT DRIVEN MUCH ON A DAILY BASES...MOSTLY ON LONG TRIPS OUT OF TOWN. *TR

I WAS TRAVELING ON A LOCAL HIGHWAY AT THE POSTED SPEED LIMIT WHEN I WAS CAUSED TO SLOW DUE TO TRAFFIC. WHEN I PRESSED THE BRAKE PEDAL THE PEDAL WENT COMPLETELY TO THE FLOOR. SCARED TO DEATH I ALMOST ENGAGED THE EMERGENCY BRAKE TO ENSURE THE VEHICLE WOULD STOP IN TIME. MIND YOU I WAS TRAVELING WITH THREE CHILDREN AND MY SPOUSE IN THE VEHICLE ALL OF WHOSE LIVES COULD HAVE BEEN AFFECTED NOT TO MENTION MY OWN. THERE WAS NO INDICATION OF ANY BRAKE SERVICE NEEDED UNTIL THIS OCCURRED AT THE POINT MY FOOT WAS LITERALLY ON THE FLOOR THE SERVICE BRAKE SIGNAL SHOWED AND DINGING OCCURRED. I ARRIVED HOME WITHOUT INCIDENT AN HOUR LATER BUT STILL NO PRESSURE TO THE BRAKE PEDAL AND EACH TIME IN ORDER TO STOP I HAD TO APPLY TONS OF PRESSURE SO THE BRAKE PEDAL WOULD TOUCH THE FLOOR. I CHECKED THE BRAKE FLUID AND IT WAS MUCH LOWER THAN WHEN WE STARTED OUR TRIP JUST A FEW HOURS PRIOR. I IMMEDIATELY ADDED FLUID. THE FOLLOWING DAY A LARGE SPOT IN THE DRIVEWAY WAS NOTICED AT THE LEFT REAR OF THE VEHICLE. MY SPOUSE CHECKED THE LINE AND SURE ENOUGH THE LINE HAD RUSTED CAUSING A LEAK. I DO NOT RESIDE IN A HIGH SALT AREA NOR DID THE PREVIOUS OWNERS. NORTHERN VA FOR PRIOR OWNERS AND I RESIDE IN THE "CENTRAL" VA AREA. THIS IS NOT ONLY A MAJOR ISSUE BUT A HUGE SAFETY CONCERN. I HAD NOT REALIZED THAT THERE WERE THOUSANDS OF COMPLAINTS FOR THE SAME EXACT ISSUE AS WHAT I NOW HAVE. REGARDLESS OF WARRANTY A VEHICLE LESS THAN 10YRS OF AGE SHOULD NOT HAVE CORRODED BRAKE LINES AND FAIL TO WARN THE OWNER AND OPERATOR UNTIL IT IS IN FACT TOO LATE. LUCKILY I DID NOT CAUSE AN ACCIDENT BUT EASILY THERE COULD HAVE BEEN ONE. YET AGAIN ANOTHER GM VEHICLE HAS SUCCEEDED IN BEING NOTHING BUT A SAFETY ISSUE, DEATH TRAP AND EXTREME DISAPPOINTMENT. *TR

I LIVE IN SAN FRANCISCO AND WAS DRIVING DOWN MY STREET. I LIVE ON A STEEP HILL AND MY BRAKES AND POWER STEERING FAILED. I HAD MY TRUCK TOWED TO THE NEAREST REPAIR SHOP AND FOUND THAT THERE IS A KNOWN DEFECT IN THE GASKET BETWEEN THE POWER STEERING AND THE BRAKE SYSTEM. IT FAILS. GMC KNOWS THIS. I HAVE HAD THIS GASKET REPLACED THREE TIMES IN 5 YEARS AND IT HAS FAILED AGAIN. WHAT CAN I DO? *TR

WINTER 2014, CONNECTICUT - BACKING OUT OF DRIVEWAY PEDDLE FELT MUSHY AND GOING DOWN FARTHER THAN NORMAL. DROVE SON TO SCHOOL QUARTER MILE TO SCHOOL AND NOTED THE LACK OF BRAKING ABILITY. LUCKILY ROLLING STOPS AND KEEPING DISTANCE FROM OTHER CARS ALLOWED ME TO GET BACK HOME. LOOKED UNDER CAR, DRIPPING BRAKE FLUID FROM UNDER MIDDLE OF CARD. HAD THE SENSE TO HAVE IT TOWED TO THE DEALER; FOR THE $2400 ESTIMATE, THEY ALSO SAID THAT MY TRANSMISSION LINES WERE LEAKING SO ESTIMATE ALSO INCLUDED THE LABOR/PARTS TO REPLACE BOTH SETS OF LINES TO FIX BOTH LINE RELATED ISSUES. I'VE ALSO HAD THE MISS PLEASURE OF HAVING TO REPLACE THE TRANSMISSION ($3500) THIS YEAR AS WELL. SLIPPING AND EVENTUALLY IT WAS GOING TO CAUSE AN ACCIDENT SO HAD TO OPEN THE WALLET FOR THAT. ANOTHER ISSUE (ELECTRICAL) - I SHUT THE CAR OFF WITH THE BLOWER MOTOR ON (HEATER IN THE WINTER) AND THE BLOWER MOTOR STAYED ON EVEN AFTER THE CAR WAS SHUT OFF, NO KEYS. IT CONTINUED TO RUN AND WOULD HAVE DRAINED THE BATTERY HAD I NOT DISCONNECTED THE BATTERY. PULLING THE FUSE HAD NO EFFECT. ($600) I HAVE ALSO HAD TO REPLACE BOTH THE FRONT AIRBAG SENSORS IN THE FRONT BUMPER. ONE WENT AND TWO WEEKS LATER THE OTHER WENT. NO IMPACTS, THEY JUST DIED. ($1200 FOR BOTH). I HAVE ALSO HAD TO REPLACE THE REAR AIR SHOCKS ($2500) I BOUGHT THIS CAR USED (SUPPOSEDLY GM CERTIFIED)) FROM A CHEVY DEALER NOT MORE THAN 3 YEARS AGO WITH 75K MILES. I NOW HAVE 99K MILES. AS I SIT AND TYPE THIS ALL DOWN FOR THIS SUBMISSION, I REALIZE JUST HOW MUCH HAS GONE WRONG WITH THIS CAR & MATCHES UP WITH OTHER OWNER STATEMENTS ON THIS WEBSITE. *TR

MY FAMILY AND I WERE TRAVELING SOUTH ON I-95 NEAR COLONIAL HEIGHTS, VA: AUTO IN FRONT OF ME MADE A SUDDEN STOP AND I SLAMMED ON THE BRAKES. THE BRAKE PEDAL WENT TO THE FLOOR; NO BRAKE WARNING LIGHTS, LUCKILY THE CAR IN FRONT PROCEEDED AND I MISSED HITTING HIM BY ABOUT 3 FEET. MADE IT TO THE NEXT EXIT RAMP AND HAD VERY LITTLE BRAKES, USING PARKING BRAKE, AND NOW THE WARNING LIGHTS WERE COMING ON. PULLED INTO GAS STATION, BIG PUDDLE UNDER THE VEHICLE; REAR BRAKE LINE RUSTED OUT AND BLOWN. THIS IS SUPPOSED TO BE A SPLIT BRAKING SYSTEM, BUT THE FRONT BRAKES WOULD NOT HOLD EITHER. HAD THE CAR TOWED 25 MILES BACK TO MY HOME GMC DEALER FOR REPAIRS. THEY INFORMED ME THAT ALL OF MY BRAKE LINES NEEDED REPLACEMENT AS THEY WOULD NOT HOLD PRESSURE AND WERE RUSTED. TO REPLACE THE BRAKE LINES WAS ABOUT $1,500.00. DUE TO USING THE PARKING BRAKES DAMAGE WAS ALSO DONE TO THE REAR ROTORS AND PARKING BRAKE PADS, THAT WAS ANOTHER $300.00. I'VE HAD THIS VEHICLE SINCE 2008, IT'S A WEEKEND OR TRIP DRIVER. SINCE I'VE HAD IT HAS NEVER BEEN DRIVEN IN SNOW OR ON THE STREET UNTIL ALL THE SALT RESIDUE HAD BEEN WASHED AWAY. FROM MY RESEARCH THIS IS A VIRGINIA VEHICLE, NOT IN THE SALT BELT. I ALSO HAVE A 2004 GMC YUKON SLT; WENT UNDER IT YESTERDAY AND THE BRAKE LINES ARE RUSTED ON THAT TOO. FUNNY THE FUEL LINES RUN NEXT TO THEM BUT THEY ARE NOT RUSTED. I WILL ENTER THAT ONE ALSO IN THE DATABASE, THEY WILL SURELY FAIL IF NOT REPLACED. *TR
