2003 GMC Yukon Xl 1500

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

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

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

WHEN TRAVELING AT ANY RATE OF SPEED, THE REDUCE ENGINE POWER LIGHT COMES ON AT I LOSE ALL POWER. I MUST TRY AND PULL OVER AT A SAFE PLACE, STOP THE CAR, TURN OFF IGNITION AND WAIT 10-15 SECOND BEFORE STARTING AND JUST HOPE IT WILL RETURN TO NORMAL MODE. THIS CAN HAPPEN MANY TIMES IN ONE DAY AND THEN IT MAY NOT HAPPEN AT ALL FOR LONG PERIODS OF TIME. VERY DANGEROUS! I HAVE BEEN DRIVING 70 MPH AND HAD TO IMMEDIATELY TRY AND PULL OVER OUT OF SPEEDING TRAFFIC, ONTO A SHOULDER AND STOP MY CAR WITH MY CHILDREN. *TR

TL* THE CONTACT OWNS A 2003 GMC YUKON XL K1500. THE CONTACT STATED THAT THE SPEEDOMETER WAS READING INACCURATELY AND REMAINED STUCK ON A SPECIFIC SPEED. SHE WAS UNABLE TO DETERMINE HOW FAST OR SLOW SHE WAS TRAVELING. THE FAILURE OCCURRED INTERMITTENTLY. IN MAY 2011, THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC AND REPAIRED. THE DEALER ADVISED THE CONTACT THAT A SPECIAL POLICY BULLETIN WAS ISSUED; HOWEVER, THE VEHICLE MILEAGE EXCEEDED THE LIMITATIONS AND DID NOT PERFORM ANY REPAIRS. THE MANUFACTURER WAS AWARE OF THE FAILURE. THE CURRENT MILEAGE WAS 141,000. THE APPROXIMATE FAILURE MILEAGE WAS UNKNOWN. UPDATED 09/15/11 *BF UPDATED 09/26/11

I WAS BACKING THE VEHICLE INTO THE GARAGE. WHILE MANEUVERING BACK AND FORTH I STEP ON THE BRAKE PETAL TO SHIFT BACK TO FORWARD. THE VEHICLE STOPPED THEN THE PETAL WENT TO THE FLOOR BOARD ABRUPTLY. THE VEHICLE MOVED AND STUCK THE HOUSE. THE REAR BRAKE LINE HAD SPLIT OPEN AT THE ABS BRAKING VALVE. ALL OF THE BRAKE LINES AT THE VALVE WERE SEVERELY ROTTED. HAD TO REPLACE ALL THE STEEL LINES TO MAKE THE VEHICLE SAFE.

THIS IS THE SECOND TIME FOR THIS PROBLEM TO OCCUR WITH THIS VEHICLE. I FILED A COMPLAINT ( 10398842 ) WITH YOUR DEPARTMENT ON 05/03/2011. SINCE THAT DATE, WE DROVE THE VEHICLE TO DALLAS, TX FOR A CONVENTION WITH NO VEHICLE PROBLEMS. THEN ON JUNE 5TH, WE WERE RETURNING FROM HOUSTON WHEN THE VEHICLE WITHOUT ANY WARNING GAVE A MESSAGE THAT THE ENGINE WAS GOING TO REDUCED POWER WHILE WE WERE DRIVING IN TRAFFIC. WE HAD TO WORK OUR WAY TO A SAFE AREA TO PARK BECAUSE WE WERE A HAZARD TO OTHER DRIVERS. THIS AFTERNOON I CALLED GENERAL MOTORS TO GET SOME RESPONSE TO THIS PROBLEM. I WAS TOLD AGAIN THAT THE ENGINE WAS PROTECTING ITSELF FROM DAMAGE. AGAIN, I ASKED IF IT WAS MORE IMPORTANT TO PROTECT THE ENGINE THAN THE OCCUPANTS, THE REPRESENTATIVE WAS RATHER TESTY ABOUT THE ISSUE. THERE WAS NO RESPONSE WHEN I SAID THAT NO AUTOMOBILE IN AMERICA SHOULD SHUT DOWN IN TRAFFIC FOR A NON EMERGENCY. ESPECIALLY SINCE THE DRIVER LOOSES CONTROL OF THE OPERATION OF THE VEHICLE. I HAVE A PICTURE OF THE INSTRUMENT CLUSTER DURING THE REDUCED POWER INTERVAL WHICH SHOWS THAT ALL GAUGES WERE NORMAL SO THERE WAS NO REASON TO EXPECT ANY ISSUES WITH THE VEHICLE. THE ENGINE WAS AT 500 RPM AND WOULD NOT GAIN SPEED. THIS IS CAUSING US TO FEAR DRIVING THIS VEHICLE. IN ANY CASE, I CANNOT SEE ANY REASON FOR ANY VEHICLE ON THE AMERICAN ROADS TO BE UNDER THE CONTROL OF ITSELF WHILE IN TRAFFIC. THE PASSENGERS SHOULD BE THE PRIMARY CONCERN. I HOPE YOU CAN GET TO THE BOTTOM OF THIS BEFORE AN ACCIDENT OCCURS WITH THIS VEHICLE. IF THERE ISN'T A CURRENT RECALL ON THIS VEHICLE FOR THIS PROBLEM, SHOULD THERE BE? THIS IS A LOW MILEAGE WELL MAINTAINED VEHICLE. *TR

WIFE WAS DRIVING TRUCK AT APPROX 30 MPH WHEN DIC ILLUMINATED WITH SERVICE BRAKE SYSTEM MESSAGE. SHE THEN PRESSED THE PEDAL AND IT WENT TO THE FLOOR. SHE WAS ABLE TO MANEUVER THE VEHICLE WHICH WOULD NOT STOP FROM HITTING ANYTHING/ANYONE. ONLY AFTER PUMPING THE PEDAL DID THE TRUCK STOP. UPON INSPECTION THE BRAKE LINES HAVE ROTTED/CORRODED ALONG THE DRIVERS SIDE FRAME RAIL. IF THIS WOULD HAVE HAPPENED AT HIGHWAY SPEEDS, SOMEONE COULD HAVE BEEN KILLED. THE VEHICLE IS PARKED NOW, AND HAS NOT BEEN REPAIRED AS OF YET. *TR
