1999 GMC Sierra 1500 complaints

I HAVE SEVERE FRAME RUST TO THE POINT WHERE THE FRAME HAS A CRACK HALFWAY AROUND IT NEAR THE REAR SUSPENSION. THE FACTORY MOUNTED TOW HITCH LITERALLY BROKE COMPLETELY OFF OF THE FRAME DUE TO THE AMOUNT OF RUST THAT WAS BUILT UP AROUND THE WELDS WHILE I WAS TOWING MY CAMPER, LUCKILY I HAD JUST MADE IT HOME FROM A TRIP FROM CAMPING WHEN THIS OCCURRED. I CAN LITERALLY PEEL OFF 1/8" THICK PIECES OF RUST AT A TIME, THE TRUCK IS NO LONGER OPERABLE DUE TO THE SAFETY ASPECT, I HAVE NEVER SEEN RUST LIKE THIS ON ANY VEHICLE, EVEN ONES THAT HAVE BEEN AROUND THE OCEAN AND SALT, AFTER READING MANY COMPLAINTS ABOUT THE SAME ISSUES WITH THESE PARTICULAR MODEL AND YEAR TRUCKS RANGING FROM 1999-CURRENT I HAVE DECIDED TO FILE A COMPLAINT, MAYBE IF YOUR ADMINISTRATION GETS ENOUGH OF THESE COMPLAINTS SOMETHING CAN BE DONE TO CORRECT THE ISSUE AND HOPEFULLY GM WILL DO SOMETHING TO COMPENSATE SO MANY OF THEIR DISAPPOINTED CUSTOMERS OR BETTER YET FIX THE ISSUE, THIS WILL BE THE LAST GM TRUCK I PURCHASE DUE TO THEIR NEGLIGENCE AND AFTER READING 100'S OF COMPLAINTS OF THE SAME ISSUE GM DOESN'T SEEM TO CARE THEY JUST GIVE THE RUN AROUND JUST LIKE WHEN I HAVE HAD PROBLEMS WITH MY VEHICLES IN THE PAST UNDER WARRANTY. *TR

UPON LEAVING MY DRIVEWAY TO THE FIRST INTERSECTION THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOORBOARD. I GOT THE TRUCK HOME AND PARKED IT. I THOUGHT THE ANTI-LOCK PART WAS PROBABLY THE PROBLEM. EXPENSIVE AS THAT PART IS I JUST LET THE TRUCK SIT. ONE DAY I LEFT A PIECE OF CARDBOARD UNDER THE TRUCK AND ISOLATED THE LEAK TO TWO RUSTED OUT LINES AT THE PLASTIC CLIP ON THE FRAME. THIS AREA MUST HOLD MOISTURE AND DOESN'T DRY-OUT, ALLOWING IT TO RUST. *TR

THE SEAT LATCHES THAT HOLD THE SEATS IN PLACE WHICH ARE MADE OF PLASTIC BREAK AND THE SEAT SLIDES BACK AND FORTH (ALL THE WAY BACK AND ALL THE WAY FORWARD TOWARD THE STEERING WHEEL). THE LATCHES ON MY 1999 GMC SIERRA PICK UP TRUCK BROKE IN 2000 WHEN THE TRUCK ONLY HAD ABOUT 3700 MILES ON IT. GMC CORP. HAS DENIED THE PROBLEM AND REFUSES TO TALK TO ME ABOUT FIXING THE PROBLEM. IT IS A REALLY BAD SAFETY HAZARD SINCE THEY COULD BREAK AT ANY TIME AND WOULD SLAM YOU FORWARD IF YOU STEP ON THE BRAKES AND BACKWARD WHEN YOU ACCELERATE. I ASK THE DEALER ABOUT FIXING IT BUT THEY REFUSED, SAYING IT WOULD COST $600.00 OR MORE JUST BUY THE FRAME FOR THE SEAT. SO IT HAS BEEN TIED WITH BAILING WIRE EVER SINCE TO HOLD IT IN PLACE. IS THERE A RECALL? *TR

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT THE LOCKING MECHANISM ON THE DRIVER SIDE SEAT FRACTURED AND AS A RESULT, THE SEAT WOULD SLIDE BACK AND FORTH ABNORMALLY. THE VEHICLE WAS NOT TAKEN TO THE DEALER AND THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND THE CURRENT MILEAGE WAS 107,000.

BRAKES FAILED AS I WAS JUST LEAVING THE FRONT OF MY HOUSE , TOW TO GARAGE $65.00 INSTALLED ALL NEW BRAKE LINES FROM MASTER CYLINDER TO ABS PUMP AND FROM ABS PUMP TO EACH WHEELS FLEX LINE COST OF $300.49, HAZARDOUS MATERIALS$10.00,LABOR $500.00 . *TR

I WAS DRIVING ABOUT 35MPH AND I WAS COMING TO A RED LIGHT SO I PUT ON THE BRAKES AND I HEARD A POP AND MY BRAKE PEDAL WENT TO THE FLOOR AND I ALMOST WENT THRU THE INTERSECTION. I GOT OUT OF MY TRUCK AND SAW THAT I WAS LEAKING BRAKE FLUID FROM THE FRONT. I OPENED THE HOOD AND SAW MY FRONT BRAKE LINE WAS LEAKING AROUND A CORRODED AREA ON A HARD BRAKE LINE ATTACHED THE FRAME RAIL. IT WAS A HARD BRAKE LINE FAILURE NOT A RUBBER LINE LIKE IN THE WHEEL WELL. I CANT BELIEVE THAT A TRUCK THAT IS 12 YEARS OLD HAS A BRAKE LINE RUST THRU, THIS IS VERY DANGEROUS. *TR

WAS DRIVING TO THE DUMP AND THE BRAKES FAILED.. PEDAL WENT ALL THE WAY TO THE FLOOR. ALMOST CRASHED BUT WAS ABLE TO STOP WITH EMERGENCY BRAKE. BRAKE FLUID WAS PORING OUT FROM UNDER DRIVERS SEAT. *TR

WAS DRIVING HOME AND NOTICED THAT WHEN THE BRAKE WAS PRESSED IT HAD TO BE PRESSED HARDER TO STOP. ONCE ARRIVING HOME NOTICED THAT BRAKE FLUID WAS LEAKING FROM UNDER THE DRIVER SIDE REAR TIRE. THE BRAKE LINE IS RUSTED, CORRODED AND HAS A BREAK IN THE LINE. THIS IS ABSOLUTELY UNACCEPTABLE. *TR

I WAS PARKED IN FRONT OF MY HOME. I WAS GETTING READY TO LEAVE FOR WORK AND I PRESSED THE BRAKE PEDAL DOWN TO START THE TRUCK AND THE BRAKE PEDAL WENT TO THE FLOOR. I HAD THE WINDOW DOWN SO EVERYTIME I PRESSED THE BRAKE PEDAL I HEARD THE PRESSURE OF THE BRAKE FLUID BEING PUSHED OUT THE BROKEN BRAKE LINE. IT COST 350.00 JUST TO GET REPAIRED PLUS A TOW. MY MECHANIC SAID IT WAS CAUSED BY THE BRAKE LINE BEING CORRODED. IT WAS ONLY ONE OF THE FOUR BRAKE LINES ON MY TRUCK BUT THE MECHANIC SAID THE OTHER ONES LOOK PRETTY BAD ALSO AND DON'T HAVE THE MONEY TO REPLACE ALL OF THEM. *TR

I NOTICED A STRONG ODOR OF GAS COMING FROM UNDER THE TRUCK. I ONLY NOTICED THE FUEL LEAKING WHEN THE TRUCK WAS ON A DOWNHILL GRADE. I CLIMBED UNDER THE TRUCK TO SEE WHERE IT WAS COMING FROM. IT TURNS OUT THAT THE FUEL LEAK IS COMING FROM THE RETURN LINE ON THE FRAME UNDER WHERE THE FUEL FILTER IS ATTACHED. THAT SECTION OF THE FUEL LINE IS TOTALLY CORRODED AND FUEL IS SLOWLY DRIPPING FROM IT. I AM TAKING IT TO MY MECHANIC TOMORROW FOR REPAIR. THE BRAKE LINE RIGHT ABOVE THE FUEL LINE IS ALSO SEVERELY CORRODED. GM REALLY NEEDS TO RECALL AND FIX THESE ISSUES DUE TO THESE CORRODED FUEL AND BRAKE LINES. I WILL NEVER BUY ANOTHER GM PRODUCT AGAIN. *TR

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, HE APPLIED THE BRAKES AND THE PEDAL DEPRESSED TO THE FLOOR. THE BRAKE LIGHT ALSO ILLUMINATED ON THE INSTRUMENT PANEL AFTER THE FAILURE. THE VEHICLE WAS SAFELY MANEUVERED TO THE SHOULDER, WHERE THE CONTACT NOTICED THAT ALL OF THE BRAKE LINES WERE CORRODED AND BRAKE FLUID WAS LEAKING. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND THE CURRENT MILEAGES WERE 94,320.

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THE VEHICLE WAS PARKED WHEN HE NOTICED THE TAILGATE WAS PARTIALLY DETACHED FROM THE HINGE. ONE OF THE CABLES THAT HELD THE LIFT GATE UP WAS ALSO FRACTURED. THE VEHICLE WAS NOT TAKEN TO THE DEALER NOR WAS THE FAILURE DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND STATED THE VEHICLE WAS NOT INCLUDED IN THE NHTSA RECALL CAMPAIGN ID NUMBER 06V066000, STRUCTURE BODY, TAILGATE:HINGE AND ATTACHMENTS. THE FAILURE MILEAGE WAS 150,000.

MY GMC SIERRA HAS THE 5.3 V8 ENGINE AND THREE OF THE EXHAUST MANIFOLD BOLTS ARE BROKEN OFF AND IT IS LEAKING EXHAUST FUMES .THESE BOLTS SHOULD NOT BREAK OFF SO EASILY.I FEEL THIS IS A SAFETY ISSUE AND A RECALL SHOULD BE ISSUED TO REPAIR THIS PROBLEM. I KNOW OTHER OWNERS WHO HAVE THE SAME PROBLEM. *TR

RETURNING HOME TURNED ONTO PROGRESS DR. XENIA, OH. HAD TO MAKE A RAPID STOP (CAR PULLED OUT IN FRONT OF ME), BRAKES FELT SOFTER, PULLED INTO SIOUX DR. XENIA, OH. TO PICK UP WIFE AND HEAD A FAMILY MEMBERS HOUSE. DROVE UP SIOUX DR. STOPPED AT THE STOP AND TURNED ONTO MAUMEE DR., WENT TO PUSH ON BRAKE PEDAL IT WENT TO THE FLOOR, DROVE BACK HOME AND FOUND BRAKE FLUID DRIPPING ON THE DRIVEWAY. FOUND THAT BRAKE LINE NEXT TO FRAME OF TRUCK WAS LEAKING. LATER FOUND BRAKE FLUID ON FRONT DRIVEWAY WHERE I HAD STOP EARLIER. *TR

FOUND THE EXHAUST MANIFOLD BOLTS ON BOTH SIDES OF THE ENGINE SNAPPING OFF FOR NO REASON AT ABOUT 65K MILES. WHEN I ASKED THE LOCAL DEALER ABOUT THIS THEY STATED THEY WOULD NEED TO REMOVE AND RESET THE ENGINE HEADS IN ORDER TO REMOVE THE BROKEN BOLTS. I DID NOT HAVE THEM REPAIR THE PROBLEM DUE TO THE COST THEY QUOTED. I NOW HAVE THREE BOLTS ON EACH SIDE WHICH HOLD THE MANIFOLDS IN PLACE. THE PROBLEM SEAM TO HAPPEN AT THE CHANGE OF THE SEASON FROM FALL TO WINTER. IN THE EXTREME COLD WEATHER, ON A COLD START UP, THERE IS AN OBVIOUS EXHAUST LEAK. AS THE ENGINE HEATS UP THE LEAK DOES DISAPPEAR. THIS IS A SAFETY HAZARD DUE TO THE FACT IF THE ENGINE EXHAUST BLOW BY IS TRANSFERRED INTO THE CAB THE DRIVER COULD BECOME UNCONSCIOUS AND DEATH COULD OCCUR. *TR

1999 GMC SIERRA, TWO CARS INFRONT TURNING LEFT, WENT TO APPLY BRAKES AND PEDAL WENT TO FLOOR, NO BRAKES. ENDED UP CRASHING INTO THE CAR IN FRONT OF ME, WHICH IN TURN HIT THE CAR TURNING. AS I WAS MAKING SURE NO ONE WAS HURT, I NOTICED THAT MY TRUCK WAS LEAKING BRAKE FLUID ALL OVER THE ROAD. *KB

WHILE DRIVING HIGHWAY SPEED (70 MPH) MY GRANDSON PRESSED ON THE BRAKE TO SLOW DOWN AT AN EXIT AND LOST ALL BUT 1/2 IN OF BRAKE PEDAL. NO ACCIDENT BUT BARELY STOPPED BEFORE AN ACCIDENT OCCURRED. AND HE IS ONLY 17 YRS OLD AND WAS BADLY SCARED.. REPAIR SHOP CHANGED THE REAR BRAKE LINE FROM THE ABS MODULE TO THE REAR BRAKE CONNECTION DUE TO BEING RUSTED THROUGH. COST WAS $451.00. IT WAS ALSO NOTED THAT THE OTHER 5 BRAKE LINES AT THE ABS MODULE WERE BADLY RUSTED AND NEEDED REPLACEMENT. *TR

BROKEN EXHAUST MANIFOLD BOLTS. FACTORY INSTALLED EXHAUST MANIFOLD BOLTS ROUTINELY BREAK ON BOTH SIDES OF THE ENGINE. NATURE OF THE FAILURE AND LOCATION OF THE BROKEN BOLTS IN THE HEADS OF THE ENGINE MOST OFTEN NECESSITATE VERY EXPENSIVE PROFESSIONAL REPAIR. *TR

ON APRIL 15 2010, AS I WAS BRINGING MY VEHICLE TO A STOP, THE BRAKE PEDAL TRAVELED ALL THE WAY TO THE FLOOR. WHEN I GOT UNDER THE VEHICLE TO EXAMINE IT I SAW THE REAR RIGHT BRAKE LINE WAS LEAKING BRAKE FLUID BADLY DUE TO A BREAK IN THE METAL BRAKE LINE. AGAIN ON 2/27/2011, I WAS STOPPING MY VEHICLE AT A STOP SIGN AND THE SAME THING HAPPENED AT A LOW SPEED. ONLY THIS TIME IT WAS A FRONT RIGHT BRAKE LINE. LUCKILY IN MY INCIDENTS THERE WERE NO ACCIDENTS OR INJURIES OR DEATHS, BUT THIS IS A SERIOUS ISSUE WITH THESE VEHICLES, ALL THE REST OF MY BRAKE LINES ARE IN VERY POOR CONDITION AT THIS TIME AND WILL ALSO NEED TO BE CHANGED SO I FEEL SAFE DRIVING MY TRUCK, ESPECIALLY WHEN MY FAMILY IS WITH ME. I HAVE OWNED TWENTY PLUS VEHICLE IN MY TIME AND EVEN SOME OF THEM WHERE GENERAL MOTORS, BUT I HAVE NEVER SEEN A VEHICLE DETERIORATE THE WAY THAT THIS ONE IS.

'99 GMC SIERRA RUST ISSUES. ON BOTH SIDES, THE CAB CORNERS AND KICKER PANELS ARE HAVE ROTTED AWAY. WHEEL WELLS ARE JUST AS BAD. THIS IS NOT A FREAK OCCURRENCE. I HAVE SEEN THE SAME MAKE AND YEAR OF TRUCKS IN MANY STATES WITH THE SAME ISSUE. *TR

OVER THE PAST 3 YEARS LIGHTED ODOMETER AND DRIVE DISPLAY FLICKER ON AND OFF. NOTICED THAT DISPLAY WOULD NOT WORK IN COLD TEMPS. APPROXIMATELY 6 MONTHS AGO LOST ALL DISPLAY. VEHICLE HAS APPROXIMATELY 96000 MILES ON IT. *TR

BRAKES FAILED DUE TO BRAKE LINE BURSTING BECAUSE OF CORROSION ON 1999 GMC TRUCK. *TR

1999 GMC SIERRA TRUCK HAD COMPLETE BRAKE FAILURE CAUSING ME TO HIT THE CAR IN FRONT OF ME AT A STOP LIGHT. NO INDICATIONS OF BRAKE PROBLEMS AND WHEN ATTEMPTING TO SLOW FOR THE LIGHT, THE BRAKE PEDAL WENT TO THE FLOOR. *TR

SEVERE CORROSION OF THE BRAKE LINES BECAME APPARENT DURING A SUDDEN APPLICATION OF THE BRAKES WHICH CAUSED MULTIPLE BRAKE LINES TO RUPTURE AND LEAVE THE VEHICLE WITH NO BRAKES SINCE A LINE FROM THE MASTER CYLINDER TO THE ABS UNIT FRONT LEFT INPUT AND THE ABS TO THE REAR T LINE BLEW SIMULTANEOUSLY. WHEN REMOVING THE DAMAGED BRAKE LINES THEY LITERALLY CRUMBLED TO PIECES DUE TO CORROSION. DURING THE REPAIR TO THE BRAKE LINES SEVERE CORROSION WAS NOTED ON THE FUEL LINES ALSO.

WHILE I DRIVING MY 1999 GMC SIERRA 1500 PICKUP,THE BRAKE ACTED VERY SOFT WHEN I WAS COMING TO A STOP ON THE ROADWAY. I THOUGHT AT FIRST THAT I WAS LOW ON BRAKE FLUID. BUT WAS ABLE TO DRIVE THE TRUCK TO MY MECHANIC AND HE CHECKED IT OUT AND FOUND THE BRAKE LINES HAD CORROSION AND A SMALL HOLE OPENED UP THROW BRAKE FLUID ALL UNDER THE UNDERCARRIAGE IN THE REAR DRIVERS SIDE OF THE TRUCK. HE TOLD ME THAT THIS ISN'T THE ONLY TRUCK HE HAS SEEN THIS PROBLEM. I FEEL THAT SOMETHING NEEDS TO ADDRESSED SOON, BEFORE PEOPLE GET HURT OR KILLED BECAUSE OF THE LOSS OF THERE BRAKES. I WAS JUST LUCKY THAT I WAS DRIVING DOWN A HILL AND THE NORMAL SPEED LIMIT. I THINK THIS PROBLEM HAS BEEN OCCURRING AND NEEDS TO BE ADDRESSED TO GMC TO DO A RECALL ON ALL THERE 1999 GMC TRUCKS. *TR

MY TRUCK WAS PARKED. I STARTED MY TRUCK. I APPLIED THE BRAKE TO PUT MY TRUCK IN GEAR. THE BRAKE PEDAL WENT COMPLETELY DOWN TO THE FLOOR. I INSPECTED UNDER MY TRUCK, AND THERE WAS A PUDDLE OF BRAKE FLUID UNDER THE DRIVER'S SIDE AREA ON THE CEMENT. I SAW THAT ALL THE BRAKE LINES CONNECTED TO THE ABS ELECTRO-HYDRAULIC CONTROL UNIT ARE SEVERELY RUSTED, AND ONE OF THEM WAS LEAKING SEVERELY. I HAD MY TRUCK TOWED HOME. THERE WAS NO WARNING LIGHT ON THE DASH THAT WAS BLINKING TO TELL ME I THAT I WAS HAVING A PROBLEM WITH MY BRAKES. THEY WERE WORKING FINE PRIOR TO THIS FAILURE. I WILL DOCUMENT THE CONDITION OF THE BRAKE LINES WITH A PICTURE AND BRAKE MECHANIC WITNESSES BEFORE ANY REPAIRS. I AM IN THE PROCESS OF LOCATING A BRAKE REPAIR BUSINESS. *TR

THE BRAKE LINES UNDER THE DRIVERS DOOR ON THE FRAME ARE ALL RUSTED AND HAVE STARTED TO LEAK FROM EXCESSIVE CORROSION. JUST NOTICED THE LEAK AS THE TRUCK WAS PARKED OUTSIDE OUR HOUSE. *TR

TL*THE CONTACT OWNS A 1999 GMC SIERRA 1500. WHEN THE CONTACT ATTEMPTED TO STOP THE VEHICLE, THE BRAKE PEDAL EXTENDED TO THE FLOORBOARD. THE CONTACT SHIFTED INTO SECOND GEAR AND WAS ABLE TO STOP THE VEHICLE. THE CONTACT INSPECTED THE VEHICLE AND SAW THAT THE BRAKE LINES WERE CORRODED AND SEPARATED. THE CONTACT CALLED THE MANUFACTURER WHO STATED THAT THERE WERE NO RELATED RECALLS. THE CONTACT PLANNED TO HAVE THE VEHICLE REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 30,000.

UPON APPLYING THE BRAKES ON TO A 1999 GMC SIERRA THE BRAKE LINE RUPTURED, SPEWING BRAKE FLUID ONTO PAVEMENT AND CAUSING NEAR IMMEDIATE LOSS OF ALL STOPPING ABILITY. THE BRAKES WERE NOT APPLIED WITH EXCESSIVE PRESSURE AND THE SPEED WAS LESS THAN 15 MPH. COULD THERE BE A DEFECT WITH THE PLACING OF THE LINES THAT CAUSES THESE BRAKE LINES TO RUPTURE? UPON CHECKING WITH FRIENDS AND THE INTERNET IT HAS BECOME APPARENT THAT THIS IS NOT A RARE OCCURRENCE WITH THE GMC SIERRAS/SILVERADOS. THE REPAIR WAS QUOTED AT $1900 DOLLARS TO REPAIR THE RUPTURED BRAKE LINE AS WELL AS OTHER ASSORTED BRAKE PARTS. THIS VEHICLE HAS ALWAYS SEEMED TO HAVE SOME TYPE OF PROBLEM WITH THE BRAKES AND FOR SOME REASON IT SEEMS TO BE COMMON KNOWLEDGE WITHIN THE AUTOMOTIVE REPAIR INDUSTRY THAT THIS SPECIFIC VEHICLE WILL DEVELOP PROBLEMS WITH ITS BRAKES. IF I WERE USING ANY SPEED WITH THIS RUPTURE OCCURRED, I AM SURE THE OUTCOME WOULD HAVE BEEN MORE SERIOUS. *TR

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT UPON STARTING THE VEHICLE, THE BRAKE WARNING LIGHT WAS ILLUMINATED.

IN MARCH OF 2009, THE BRAKE LINE ON MY 1999 GMC SIERRA 1500 BROKE AND THE BRAKE PEDAL WENT RIGHT TO THE FLOOR. I STOPPED IN A PARKING LOT AND CHECKED ALL OVER AND FOUND THAT THE BRAKE LINE WAS RUSTED UNDER THE CAB ON THE DRIVER SIDE. THAT WAS WHERE THE LINE BROKE AND BRAKE FLUID WOULD LEAK OUT. I HAD IT FIXED FOR $650 AND ON TUESDAY, SEPTEMBER 13, 2010, THE BRAKE LINE BROKE AGAIN RIGHT AT THE REAR AXLE WHEN I WAS MOVING THE TRUCK IN MY BACKYARD. *TR

1999 GMC SIERRA ABOUT 55,000MILES: MANUAL SEAT DRIVERS SIDE: THE DEVICE THAT PREVENTS THE SEAT FROM SLIDING BACK AND FORTH FREELY ON ITS TRACKS HAS FAILED. NOW THE SEAT IS ALL THE WAY BACK EXCEPT UNDER BRAKING, WHEN IT ABRUPTLY SLIDES ALL THE WAY TO THE STEERING WHEEL. NO MATTER HOW ALERT YOU TRY TO BE, EVENTUALLY SOME MANEUVER WILL BE NEEDED WITHOUT TIME TO BRACE YOURSELF, YOUR FOOT WILL MASH THE BRAKE UNCONTROLLABLY TO THE FLOOR AS THE SEAT RUSHES FORWARD, YOUR ARMS WON'T BE ABLE TO STEER AS YOUR BODY RUSHES FORWARD INTO THE STEERING WHEEL. A HANDFUL OF BROKEN NYLON PIECES AND ZINC CASTING PIECES AND A SPRING WERE RECOVERED FROM THE STARBOARD TRACK. DEALER DOESN'T HAVE A REPLACEMENT FOR JUST THE BROKEN STUFF, THE TRACK ASSEMBLY IS INSANELY EXPENSIVE ($500 FOR BOTH SIDES) NOT COUNTING LABOR. NO JUNKYARD I CAN FIND HAS THE PART, THIS MODEL SEAT WAS ONLY MADE IN 1999. I FOUND ABOUT A DOZEN COMPLAINTS ONLINE ABOUT THIS WHEN I DID A GOOGLE SEARCH. *TR

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT WHILE BRAKING FROM UNKNOWN SPEEDS, THE BRAKES WOULD NOT ENGAGE.

1999.5 GMC SIERRA 1500 4WD EXT CAB, SHORTBED. MAY 2005 FRONT BRAKE LINE BURST WHILE APPLYING BRAKES DUE TO SLOWED TRAFFIC ON 65MPH INTERSTATE IN UPSTATE NY. USED SHOULDER TO AVOID HITTING VEHICLES IN FRONT OF ME, HOWEVER REAR BRAKES ONLY ON A 6K POUND PICKUP TRUCK, UNLOADED, DO NOT RESULT IN EFFECTIVE BRAKING. I HAD TO DOWNSHIFT MY AUTOMATIC TO USE ENGINE BRAKING AS WELL AS THE PARKING BRAKE (WHICH ALSO IS POORLY DESIGNED AND INEFFECTIVE). TRUCK WAS TOWED TO GM DEALER WHERE FRONT BRAKE LINES WERE REPLACED AS ALL WERE RUSTED/ROTTED TO UNSAFE LEVELS, WITH ONE FRACTURING CAUSING THE LOSS OF PRESSURE AND FLUID. APRIL 2009 UPON DOING AN OIL CHANGED, MYSELF, I DISCOVER THE ALL OF THE BRAKE LINES, INCLUDING THE FRONT AS WELL AS THE REAR ARE IN VERY BAD SHAPE DUE TO RUST. AFTER SPEAKING TO MY MECHANIC I HAVE LEARNED THAT THE GM BRAKE LIKE FROM THE LATE 90S TO 2004 WERE NOT PROPERLY DESIGNED TO DEAL WITH THE WEATHER AND RESIST CORROSION. HE SAID AT LEAST ONCE A WEEK HE HAS TO REPLACE SECTIONS OF GM BRAKE LINE FROM THESE TRUCKS AND SUVS. I CANNOT CURRENTLY AFFORD TO REPLACE THESE YET AS ITS A $1700 JOB DUE TO THE LABOR INVOLVED AND THE FACT THAT REPLACING WITH GM'S BRAKE LINES WILL JUST RUST AGAIN IN 2-3 YEARS. SO I NEED AFTERMARKET LINES, PROBABLY STAINLESS STEEL OR AT LEAST SOMETHING WITH A PROPER AMOUNT OF NICKEL IN IT (WHICH GM HAS SKIMPED ON!) WHICH HOPEFULLY I CAN PUT ON IN THE NEXT FEW MONTHS BEFORE I GET KILLED OR SOMEONE ELSE KILLED. APRIL 2010. *TR

1999 GMC SIERRA 1500 5.3 - I HAD BRAKE LINES FAIL ON 3 SEPARATE OCCASIONS. FIRST WAS A HARD LINE TO THE FRONT DRIVERS SIDE, HAPPENED IN MY DRIVEWAY SO NO CRASH. SECOND WAS A LINE COMING FROM THE MASTER CYLINDER. THIS WAS WHILE TOWING A TRAILER AND THE TRAILER BRAKES MANAGED TO GET US STOPPED EVEN THOUGH WE WERE ON A HILL. THE THIRD FAILURE WAS STOPPING AT A LIGHT, LUCKILY NO ONE WAS IN FRONT OF ME AND I HAD PLENTY OF STOPPING DISTANCE. AFTER THAT I REPLACED ALL OF THE REMAINING LINES ON THE TRUCK. NO PROBLEMS SINCE. *TR

BRAKE LINES FAILED ON MY 1999 GMS SIERRA PICK UP. HAD TO BE REPLACED AT A COST OF $2000.00 +'S.
