2004 GMC Yukon Xl Brakes Problems

While driving on the freeway at 75 mph I felt significant reduction in speed and the rpms went pretty high. It felt as if I had my foot on the accelerator and the brake at the same time. There was also a burnt smell. After a few minutes it went back to normal. This continued to happen sporadically so I took it to my mechanic he inspected the vehicle could not find an issue he also ran a code scan. No codes pertaining to this issue only knocker sensor and O2 sensor. I replaced those anyway. Then a few days later I was driving to work at it happened again going about 55 mph it felt like the transmission had downshift to a very low gear there was smoke and really bad burning smell. I pulled over immediately and called my mechanic. He towed the vehicle to his shop still could not find a problem. After several months of sitting I had to drive the vehicle home. After approximately 5 miles there was smoke and small flames coming from behind the front drivers side wheel. My mechanic checked the brake, it had engaged without me pressing the pedal and stuck. Now we are having issues getting brake fluid to the rear brakes. Possibly the proportioning valve.

MY 2004 YUKON HAS AT LEAST THREE MAJOR LEAKS IN THE BRAKE LINES CAUSED BY CORROSION. RESEARCH FOUND THAT THIS DEFECT WAS IDENTIFIED SHORTLY AFTER THE VEHICLES WERE SOLD NEW BUT REFUSED TO ISSUE RECALLS. I WAS IN A NEAR ACCIDENT WHEN MY BRAKES WENT COMPLETELY TO THE FLOOR SUDDENLY. ALSO THE STABILIZER SYSTEM FAILS WITHOUT NOTICE AND THE DASH INSTRUMENT CLUSTER (GAS GAUGE, TEMP GAUGE, VOLTAGE AND OIL PRESSURE GAUGES WORKS ON AND OFF.

THE BRAKE LINES ON MY 2004 XL YUKON WENT OUT LEAVING ME HELPLESS WITH MY 5 YEAR OLD TWIN DAUGHTERS. I WAS OUT DOING ERRANDS YESTERDAY WHEN I WAS TRAVELING 55 MILES AN HOUR ON A MAJOR SIDE HIGHWAY WHEN I WENT TO BRAKE AND MY FOOT WENT STRAIGHT TO THE BOTTOM OF THE FLOOR.... I WAS NOT ABLE TO STOP I WAS PETRIFIED BECAUSE I WAS IN FULL TRAFFIC. I PULLED OFF THE ROAD INTO THE GRASS TO PREVENT AN ACCIDENT. THIS WAS THE MOST FRIGHTENING SITUATION I HAVE EVER BEEN IN. WHEN MY HUSBAND ARRIVED HOME I EXPLAINED WHAT HAPPENED , HE LOOKED UNDER THE TRUCK TO FIND ALL I SAID ALL OF MY BRAKE LINES WERE CORRODED AND RUSTED AND CRUMBLY TO THE GROUND. HE SAID HE NEVER SAW ANYTHING LIKE THIS. WE HAVE HAD SEVERAL USED CARS IN OUR LIFETIME AND THIS IS THE FIRST TO EVER EXPERIENCE BRAKE LINE FAILURE!!!!!! I CALLED GM TO DISCUSS MY DILEMMA AND HOPEFULLY GET HELP WITH THE REPAIR AND CONFIRM MY HUSBANDS FINDINGS. WE WERE ADVISED THEY WILL DO THE TOW TO THE DEALERSHIP FOR THE DIAGNOSTIC,BUT WE WOULD HAVE TO PAY FOR THE DIAGNOSTIC. WE WERE ALSO ADVISED THIS WAS A MAINTENANCE ISSUE. WELL IF WE WOULD HAVE EVER THOUGHT THAT WE WOULD NOT BE IN THIS PREDICAMENT TODAY... WELL HERE I AM STILL WAITING TO HEAR BACK FROM THEM ABOUT THE TOW. I ALSO CALLED THE GM DEALERSHIP AND THEY SAID THEY ARE AWARE OF THE PROBLEM AND THEY HAD SEVERAL CARS IN THERE DEALERSHIP RIGHT NOW FOR BRAKE LINE REPAIR, BUT COULD DO NOTHING WITH ABSORBING THE REPAIR COST. I WOULD HAVE TO GO TO GENERAL MOTORS AND TAKE IT UP WITH THEM.... AT THIS POINT I AM THANKFUL FOR BEING ALIVE WITH MY BEAUTIFUL TWIN DAUGHTERS WHICH COULD HAVE BEEN CRIPPLED , DISMEMBERED OR EVEN DEAD I AM SEEKING FROM GENERAL MOTORS COMPENSATION FOR REPAIRS OF MY BRAKELINES ON MY GM XL YUKON 2004. *TR

I HAVE A 2004 GMC YUKON XL AND ON 10/21/13 MY BRAKE COMPLETELY GAVE OUT. LUCKILY I WAS ONLY GOING ABOUT TEN MPH AND WAS ABLE TO ROLL TO A STOP. THIS WAS A VERY SCARY AND UNSAFE CONDITION. MY SON USUAL DRIVES THIS TRUCK TO SCHOOL AND WORK THANK GOD HE WAS NOT BEHIND THE WHEEL. UPON INSPECTION I NOTICED THE BRAKE LINES ARE COMPLETELY CORRODED. THE BRAKE LINE UNDER THE DRIVERS SIDE FRONT DOOR JUST BEHIND THE ABS UNIT CORRODED THROUGH. ALL OF THE BRAKE LINES SHOW MAJOR CORROSION. THIS VEHICLE ONLY HAS 76,500 MILES ON IT. THIS SHOULD NEVER HAPPEN TO A VEHICLE WITH THIS LITTLE USE. MAY I ADD THAT I KEEP THE VEHICLE MECHANICALLY AND COSMETICALLY METICULOUSLY MAINTAINED. I WOULD LIKE TO BE NOTIFIED IF THERE IS ANY ACTION TAKEN BY GMC TO RESOLVE OR REPAIR THESE ISSUES. FURTHERMORE IF ANY CLASS ACTION SUIT ARISES I WOULD LIKE TO BE NOTIFIED. THROUGH MY RESEARCH THIS SEEMS TO BE A PROBLEM ALL OVER THE COUNTRY CAUSING MANY ACCIDENTS. GMC SHOULD ACKNOWLEDGE AND FIX THIS PROBLEM BEFORE SOMEONE GETS KILLED. THANKS *TR
