My kids and I was on the interstate and all of sudden my yukon reduce engine power.Dropping to 30 in a speed zone of 70.I was very afraid for our safety and appreciate there concerns for reducing engine power to save the truck,but that's very dangerous. So I paid to replace the throttle body and gas pedal cause that was the codes for the problem. But it's still doing the same thing and I don't have money to keep buying parts.Plus it a gm problem and I really need some help with the fixture..

WHILE TRAVELING AT HIGHWAY SPEED AND ROUNDING A BLIND CURVE THE TRAFFIC AHEAD HAD STOPPED DUE TO A CRASH. I HAD TO BRAKE HARDER THAN NORMAL AND THE BRAKE PEDAL JUST KEPT DEPRESSING FURTHER AND FURTHER UNTIL IT WAS ALL THE WAY TO THE FLOOR. I WASN'T STOPPING NEAR FAST ENOUGH AND HAD TO VEER TO THE LEFT INTO THE MEDIAN TO AVOID MAKING CONTACT WITH ANYONE ELSE. IT WAS RAINING AND AS I LOOKED UNDER MY TRUCK TO LOOK FOR WHY MY BRAKES WERE INEFFECTIVE BUT COULDN'T SEE ANYTHING AT THAT TIME. I CHOSE TO TRY TO DRIVE HOME NOT SURE WHY I HAD THE PROBLEM STOPPING. THE NEXT DAY WAS DRY AND I HAD MY BROTHER PUMP THE BRAKES WHILE I LOOK UNDERNEATH AND FOUND NUMEROUS PLACES WHERE THE BRAKE LINES WERE RUSTING AT AN ALARMING RATE AND ONE LOCATION WHERE THE RUSTED LINE FAILED. I REPAIRED THE LEAK I HAD FOUND AND WHEN I TRIED TO BLEED THE BRAKES FROM THAT REPAIR I WOULD BEGIN AN UNENDING RUN OF LEAKS UP AND DOWN THE METAL BRAKE LINES FOR BOTH THE FRONT AND REAR. THIS YUKON HAS AROUND 260K MILES BUT THOSE BRAKE LINES SHOULDN'T BE RUSTING THROUGH LIKE THEY ARE. I HAVE HAD MORE THAN 15 TAHOES, YUKONS, YUKON XLS, SUBURBANS, AND PICKUP TRUCKS FROM GM AND NEVER HAVE I HAD SUCH A RUN OF BRAKE FAILURES AS THIS 2004 MODEL YUKON WAS NOW GOING THROUGH. GM SAYS THIS IS NORMAL MAINTENANCE BUT HOW CAN ONE EVEN SEE IF A FAILURE IS OCCURRING AS MANY OF THESE LINES ARE CONCEALED BY THE FRAME, CHASSIS, AND BODY. I HAVE SPOKEN TO OTHER OWNERS OF SIMILAR VEHICLES, BE IT PICKUPS OR TAHOE'S OR SUBURBANS OF THE 2000 TO 2006 MODEL YEARS AND NEARLY ALL HAVE COMPLAINED OF CHRONIC BODY RUST ISSUES BUT MORE IMPORTANTLY BRAKE FAILURES FROM BRAKE LINES RUSTING AND THEN BLOWING OUT WITHOUT WARNING. MANY ALSO CITED THAT OF THE LINES THAT ARE VISIBLE TO INSPECT THEY WOULD APPEAR TO BE OK BUT JUST OUT OF VIEW ONE WOULD HAVE A SUDDEN BLOW OUT WITH NO WAY TO SEE OR KNOW THERE WAS A PROBLEM SINCE THE LINES ARE CONCEALED.

WHILE DRIVING DOWN ROAD AT APPROXIMATELY 45 MPH, HIT THE BRAKES WHEN A COUPLE OF DEER JUMPED ONTO ROAD AND THE PEDAL WENT TO FLOOR WITH NO BRAKING ACTION AT ALL. HAD ENOUGH TIME TO REALIZE WHAT HAD HAPPENED AND HIT THE PARKING BRAKE IN TIME BEFORE REACHING INTERSECTION TO BUSY HIGHWAY. INSPECTION AFTERWARD SHOWED BRAKE FLUID ON THE FRAME NEAR THE DRIVER SIDE DOOR WHERE THE PROPORTIONING VALVE IS LOCATED. THERE WAS NO WARNING OF THE FAILURE AND HAD BEEN DRIVING THE VEHICLE AROUND TOWN MOST OF THE DAY. HAVE EXPERIENCED BRAKE FAILURES ON VEHICLES BEFORE AND ALWAYS HAD HALF THE SYSTEM REMAIN OPERATIONAL ENOUGH TO STOP WITHOUT PROBLEM. THIS APPEARS TO HAVE BEEN A SINGLE FAILURE MODE THAT CAUSED THE LOSS OF BRAKING OR A SIMULTANEOUS FAILURE OF MULTIPLE SYSTEMS WHICH SHOULD BE UNLIKELY BUT SEEMS TO HAPPEN WITH IMPROBABLE REGULARITY BASED ON COMPLAINTS POSTED.

BACKING UP TO HOOK UP A TRAILER, I DEPRESSED THE BRAKE AND IT WENT STRAIGHT TO THE FLOOR. REAR BRAKE LINE RUPTURED AFTER ABS MODULE AND RIGHT ABOUT THE FUEL TANK. I CANNOT REPLACE JUST THEY ONE LINE BECAUSE OF CORROSION AND RUST AT THE MODULE. THIS IS THE FAMILY SUV AND IM LUCKY THIS HAPPENED IN MY YARD AND NOT ON THE HIGHWAY. I WAS PREPARING TO LEAVE TOWING A 5500LB TRAILER. ALL THESE OTHER LINES ARE EQUALLY BAD AND I FEAR THEY ARE GOING TO RUPTURE TOO. I'M STUCK WITH A 10 YEAR OLD LESS THAN SAFE VEHICLE.

I WAS HEADING TO OCEAN CITY MARYLAND. AS I WAS APPROACHING THE TOLL PLAZA TO GO OVER THE BAY BRIDGE I SLOWED DOWN AND SEEM TO HAD STOPPED WHEN ALL THE SUDDEN MY FOOT WAS ON THE BRAKE CLEAR TO THE FLOOR AND I HIT THE BOX TRUCK IN FRONT OF ME THAT WAS STOPPED FOR TRAFFIC. I LOOKED AT THE DASH AND IT WAS ALL LIT UP AND BLINKING. THE GENTLEMAN TOLD ME I HAD LOST MY BREAKS AND THAT WHEN HE WOULD MOVE I WOULD BEGIN TO MOVE AS WELL. I WAS NOT FAR FROM THE BEGINNING OF THE BRIDGE BUT I WAS SIX OR SEVEN LANES TO THE LEFT IN THE EASYPASS LANE. I CALLED MY BROTHER ASKING HIM WHAT TO DO AND HE TALKED ME THROUGH AS I WAS PANICKING. I HAD A FULL TANK OF GAS AND LOTS OF TRACTOR TRAILERS GOING THROUGH THE PLAZA. I WAS FOR SURE I WAS GOING TO BE HIT OR HIT SOMEONE ELSE. I ROLLED DOWN MY WINDOWS PUT MY FLASHERS ON AND BEGAN TO BLOW MY HORN AND YELLING OUT THE WINDOW I HAVE NO BRAKES SO THAT I COULD GET OVER TO THE RIGHT SIDE OF THE ROAD RIGHT BEFORE THE BRIDGE. AS I DID PEOPLE DID STOP AND LET ME GET OVER AND I HAD MY FOOT ON THE BRAKE BUT THEY WERE NOT STOPPING THE TRUCK. AS I WAS DRIFTING OVER A TOLL FACILITY TOW TRUCK WAS ON THE SIDE AND HE YELLED TO ME WHAT WAS WRONG. I TOLD HIM NO BRAKES AND HE TOLD ME TO JUMP OUT AND HE JUMPED IN AND HIT THE TRUCK UP OVER A SMALL EMBANKMENT TO GET IT OUT OF THE WAY OF ALL THE TRAFFIC. HE GOT IT TO STOP AND GOT OUT AND LOOKED UP UNDER THE TRUCK AND COULD SEE THAT TWO OF THE BRAKE LINES WERE SNAPPED. I HAD THE TRUCK TOWED WITH OVER THE BAY BRIDGE AND THEY HAD TO REPLACE THE TWO BRAKE LINES THAT SNAPPED AND THEY COULD NOT BLEED THE LINES FULLY SINCE THEY WERE AFRAID THAT THE OTHER TWO LINES COULD SNAP AT ANY TIME. I GOT HOME AND HAD TO HAVE THE OTHER TWO LINES DONE AS WELL. I HAVE TO SAY I WAS NEVER SO SCARED IN MY LIFE I COULD HAVE DIED FOR SURE IF I WAS GOING ANY FASTER UP AN OVER THE BRIDGE AND DOWN THE HILL GETTING OFF. WORST DAY OF MY LIFE.

UPON APPLYING BRAKES, WHILE DRIVING DOWNHILL, THE RIGHT REAR STEEL BRAKE LINE BURST RESULTING IN SIGNIFICANT LOSS OF BRAKING POWER. FORTUNATELY,Y I HAD SIGNIFICANT DISTANCE BETWEEN ME AND THE NEXT CAR THAT I COULD AVOID AN ACCIDENT. THE VEHICLE STILL HAD SOME BRAKING POWER TO ALLOW ME TO DRIVE IT TO A NEARBY PARKING LOT WHERE IT CONTINUED TO LOSE BRAKE FLUID. THE VEHICLE WAS TOWED TO A LOCAL GMC DEALERSHIP WHERE THEY REPLACED ALL THE STEEL LINES WITH COPPER/NICKEL LINES AT A COST OF $1,606.00. I WAS TOLD THAT THE STEEL LINES ARE RUSTING OUT AS A RESULT OF THE DE-ICING CHEMICALS BEING USED ON THE ROADS DURING THE WINTER. I HAVE HAD VEHICLES UP TO 15 YEARS OLD IN THE PAST AND NEVER HAD SUCH AN EXPERIENCE AS THIS. I QUESTION THE QUALITY OF THE STEEL LINES. IF GM IS OF THE OPINION THAT THEIR STEEL LINES CAN'T WITHSTAND THE DE-ICING CHEMICALS THEN THEY SHOULD HAVE INSTALLED COPPER/NICKEL LINES AT THE FACTORY. THANK YOU.

THE SUBJECT VEHICLE HAD RECENTLY BEEN PARKED AFTER TOWING A 29 FOOT LONG TRAVEL TRAILER. IT HAD SAT FOR APPROXIMATELY TWO WEEKS SINCE WE LAST USED IT. DURING THE 2011 30 OCTOBER SNOW STORM IN PA, I WENT TO PICK IT UP TO USE IT. I STARTED DOWN THE DRIVEWAY AND WENT TO APPLY THE BRAKES AND THE BRAKE PEDAL TRAVELED TO THE FLOOR. ALL OF THE ANTILOCK AND BRAKE WARNING LIGHTS APPEARED ON THE DASH. I WAS ABLE TO STOP THE VEHICLE AND BACK IT BACK THE DRIVEWAY AND PARK IT. WE LATER CALLED AAA AND HAD IT TOWED TO A LOCAL CHEVY DEALER. THEY DIAGNOSED THE PROBLEM AND LET US KNOW THAT THEY HAD FOUND A BRAKE LINE THAT BURST DUE TO CORROSION. THIS BRAKE LINE IS ALMOST DIRECTLY UNDER THE POWER BRAKE BOOSTER ASSEMBLY AND IS SOMEWHAT HIDDEN FROM VIEW. IT LIES ATOP THE FRAME IN THIS AREA AND ACCORDING TO THE DEALER HAD CORRODED. ACCORDING TO THE DEALER THEY HAD TO FABRICATE A REPLACEMENT BRAKE LINE AND WERE ABLE TO REPLACE IT. THEY FURTHER INDICATED THEY LOOKED AT THE OTHER BRAKE LINES AND DID NOT SEE ANY FURTHER INDICATION OF CORROSION. I HAVE DRIVEN THE GMC FOR ABOUT TEN MILES SINCE THE REPAIR AND THE BRAKES APPEAR TO BE BACK TO NORMAL. LET ME ADD THIS, I HAVE OWNED 15 DIFFERENT VEHICLES IN MY LIFE AND NOT ONE HAS HAD TO HAVE A STEEL BRAKE LINE REPLACED. THIS IS THE FIRST. JUST LIKE THE OTHER GM OWNERS, WHEN THESE LINES FAIL THE BRAKING ABILITY TO STOP THIS TWO TON VEHICLE IS ALMOST NON-EXISTENT I AM VERY THANKFUL THIS LINE DID NOT FAIL WHILE TOWING THE 29 FOOT TRAVEL TRAILER.
