2003 GMC YUKON XL Complaints

WHEN DRIVING THE VEHICLE IT DRIVES FINE BUT WHEN IT GETS TO SPEEDS AROUND 50-60 IT WILL COMPLETELY SHUT OFF I HAVE TO PUT IT ON N AND TURN THE KEY ALL THE WAY BACK AND THEN TRY STARTING IT AGAIN. AFTER IT TURNS OFF THE FIRST TIME THEN IT WILL START TURNING OFF MORE RANDOMLY. I HAVE BEEN READING ONLINE AND IT SEEMS TO BE A KNOWN ISSUE WITH THESE TRUCKS AROUND THE SAME YEAR. *TR

I STARTED MY TRUCK. I APPLIED THE BRAKES AND SHIFTED INTO DRIVE. I BEGAN TO ROLL FORWARD, THEN APPLIED MY BRAKES PRIOR TO EXITING MY DRIVEWAY. THE BRAKE PEDAL WENT TO THE FLOOR, THE BRAKE SERVICE LIGHT CAME ON AND THE TRUCK CONTINUED FORWARD. I HAD TO PUMP THE BRAKES TO COME TO A STOP. I PULLED THE TRUCK OVER AND OBSERVED BRAKE FLUID ALL OVER THE STREET. I CRAWLED UNDER THE TRUCK AND SAW THAT THE BRAKE LINE WAS RUSTED AND THAT IT BURST SOMEWHERE IN THE MIDDLE OF THE TRUCK ON THE DRIVER'S SIDE. *TR

APPROACHING A TRAFFIC LIGHT AT 35 MPH, WITHOUT WARNING THE BRAKE PEDAL WENT TO THE FLOOR. I COULD NOT SLOW THE CAR DOWN VERY MUCH AND WENT THROUGH A VERY YELLOW LIGHT. FORTUNATELY THE CAR WAITING AT THE LIGHT HAD NOT ENTERED THE INTERSECTION. THE A BRAKE LINE ROUTED ABOVE THE FRAME BLEW APART LOSING BRAKE FLUID EVERY TIME I PUMPED THE BRAKES. NO PRESSURE TO OPERATE THE REAR BRAKES. THE BREAK OCCURRED AT A RUSTED LOCATION. *TR

TL* THE CONTACT OWNS A 2003 GMC YUKON XL. THE CONTACT STATED THAT WHILE TRAVELING 30 MPH, THE REAR WINDOW DETACHED FROM THE VEHICLE ABNORMALLY. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 177,702.

I'VE COME ACROSS SEVERAL OTHERS WITH THE SAME ISSUE. MOST OF WHICH HAVE TAKEN THE ISSUE BACK TO GM DEALERS, WHO GET NO SUPPORT FOR THE PROBLEM FROM THE HOME OFFICE. I BELIEVE THIS COULD BE A VERY DANGEROUS ISSUE. THE ISSUE ITSELF IS THE TRUCK KICKS INTO "REDUCED ENGINE POWER" MODE AND THEN IT DOES NOT GO ANY FASTER THAN IDLE WHICH MEANS IT ALL OF THE SUDDEN REDUCES THE SPEED TO 5 MPH MAXIMUM AS WELL AS THE POWER STEERING GOES OUT AND THE ABS BRAKES. THAT IS VERY DANGEROUS IF YOU ARE ON THE HIGHWAY. PEOPLE HAVE BEEN TROUBLESHOOTING THE ISSUE WITH NO SOLID FIXES FROM WHAT I CAN FIND. I BELIEVE GM SHOULD COME UP WITH A FIX SO THAT ISN'T A DANGEROUS HAZARD TO CONSUMERS AND OWNERS OF WHAT LOOKS LIKE THERE 2003 MODEL YEARS, IT SEEMS TO BE MOSTLY THERE 2003 MODEL YEARS. GM DOESN'T SEEM TO WANT TO RECOGNIZE THIS AS AN ISSUE. PLEASE HELP US CONSUMERS OUT, WE WOULD JUST LIKE THIS PROBLEM SOLVED. THANK YOU VERY MUCH. *TR

WHEN STARTING MY 2003 GMC YUKON THE DASH SAYS REDUCED ENGINE POWER..IT WON'T GO OVER 15 MPH....IT HAPPENS EVERYDAY! I HAVE TO KEEP RESTARTING IT AND LET IT GET WARM BEFORE I CAN GO ANYWHERE. IF THIS HAPPENS WHILE I AM DRIVING IT, AND SOMEONE HITS ME I WILL SUE GM, AS I HAVE BEEN A LOYAL GM CUSTOMER FOR 35 YRS...IF YOU READ ALL THE COMPLAINTS ON THE WEB ABOUT THE SAME PROBLEM THEN YOU WOULD DEFINITELY ISSUE A RECALL BEFORE SOMEONE GETS KILLED. *TR

BRAKE LINES UNDER DRIVERS SEAT ARE COMPLETELY RUSTED THROUGH. VEHICLE IS GARAGE KEPT AND SEEMS TO BE EXPERIENCING EXCESSIVE RUST ON BRAKE LINES. WHILE DRIVING VEHICLE BRAKE PEDAL WENT TO THE FLOOR ALMOST CAUSING ME TO HAVE AN ACCIDENT. MY FAMILY AND I OWN AND HAVE OWNED NUMEROUS GM PRODUCTS AND WE'RE VERY DISAPPOINTED WITH THIS SAFETY HAZARD NOT BEING ADDRESSED BY GM. MAYBE IT'S TIME TO SHOP ELSEWHERE... *TR

REAR BRAKE LINE FAILURE. LINE WAS RUSTED THROUGH AND LEAKING BRAKE FLUID. NOW (FEB 2012) ANOTHER LINE IS LEAKING BRAKE FLUID, THIS TIME IN THE FRONT PORTION OF THE VEHICLE. *TR

VEHICLE SUDDENLY AND AUTOMATICALLY SWITCHED FROM 2 WD TO 4 WD LOW. DRIVER DID NOT ENGAGE 4WD LOW SYSTEM WHICH REQUIRES TO 1ST PLACE TRANSMISSION INTO NEUTRAL THEN SELECT 4 WD LOW BUTTON. DRIVER MOMENTARY LOST CONTROL OF VEHICLE (STEERING) BUT WAS ABLE TO SAFELY MOVE VEHICLE TO SIDE OF ROAD. DRIVER AND OCCUPANTS WERE JOINTED FORWARD WITH IMPACT OF ENGAGEMENT OF LOW GEARS AND IMMEDIATE LOSS OF SPEED. *TR

REDUCED ENGINE SPEED WARNING LIGHT COMES ON AND DROPS TRUCK TO AN IDLE. I FEEL THIS IS VERY DANGEROUS IN TRAFFIC AND ON HIGHWAYS. MY MECHANIC HAS NOT BEEN ABLE TO LOCATE PROBLEM. ALL FORUMS AND ONLINE HELP HAS BROUGHT ME TO DEAD ENDS. THIS IS MY LAST RESORT, I BELIEVE GM KNOWS WHAT THE PROBLEM IS AND AM HOPING THEY WILL DO THE RIGHT THING AND RECALL BEFORE SOMEONE IS SERIOUSLY HURT OR KILLED FROM THIS ISSUE. *TR
