2003 GMC YUKON DENALI Electronic Stability Control Esc Problems

LOSS OF POWER WITHOUT WARNING , WHILE ON HIGHWAY. FROM 65MPH TO 0 WITHOUT WARNING. ALMOST CAUSED A CRASH PILE UP....WAS ALMOST REAR ENDED. VERY DANGEROUS...WHOLE FAMILY CHILDREN AND ALL WAS IN THE VEHICLE.

I HAVE A 2003 YUKON DENALI I PURCHASED AND IT HAS GIVEN ME THE REDUCED ENGINE POWER LIGHT AND ALMOST HAD A FEW ACCIDENTS ON THE HIGHWAY BECAUSE IT DROPS THE SPEED TO 20 MPH ALSO IT HAS THE CHECK ENGINE CODES AS P0120 AND P2135 I HAVE BEEN AWARE THAT GM HAS NOT FOUND A SOLUTION TO THIS AND WANTED TO SEE IF THERE IS ANY RECALLS AS I AM VERY AFRAID OF BEING IN A VERY SERIOUS ACCIDENT WITH MY CHILDREN IN THE CAR. THE CONSUMER STATED THE VEHICLE WAS REPAIRED AND REQUESTED WITHDRAW THE COMPLAINT. *JS

TRUCK STARTED TO HAVE MAJOR ELETRICAL ISSUES. BLUBS BURNING OUT OFTEN SOCKETS BURNING OUT HAD TO REPLACE TOO OFTEN. LIGHT COVERS MELTING. HEADLIGHTS OUT AND WILL NOT COME BACK ON FOR DAYS, HAVE TO TAP THEM TO GET THEM TO COME BACK ON. HORN BLOWS FROM ALARM ALL TIMES OF THE DAY AND NIGHT. INSIDE LIGHTS ON DASH, STEERING WHEEL AND DOORS WILL NOT WORK AT TIMES ALL LIGHTS ARE NOT FUNCTIONING CORRECTLY. LIGHTS AT TIMES TOO OFTEN WILL NOT WORK AT ALL. STABILITY WARNING LIGHT COMES OFTEN. AFRAID TRUCK WILL CATCH FIRE FROM THE ELECTRICAL ISSUES.. PLEASE HELP!!!!

MY WIFE WAS DRIVING 75 MPH ON THE INTERSTATE WHEN SHE HEARD A "DING" AND THE INFORMATION CENTER SAID "SERVICE STABILITY" "ENGINE POWER REDUCED" IT THEN TOOK ALL ENGINE POWER FROM THE VEHICLE IMMEDIATELY CAUSING IT TO SLOW TO A VERY UNSAFE 20 MPH ALMOST INSTANTLY AND CAUSED HER TO NARROWLY AVOID BEING HIT FROM BEHIND. THIS HAPPENED SEVERAL MORE TIMES. WE TOOK THE VEHICLE IN FOR SERVICE AND WERE TOLD WE NEEDED A NEW THROTTLE BODY CABLE WHICH WE BOUGHT AND HAD THEM INSTALL, BUT THE PROBLEM HAS NEVER GONE AWAY. I HAVE READ MANY MANY COMPLAINTS ABOUT THIS ON THE INTERNET BUT AFTER YEARS OF COMPLAINING NOTHING HAS BEEN DONE. DOES SOMEONE HAVE TO DIE BEFORE SOMETHING IS DONE? IT CERTAINLY SEEMS LIKE IT. I FILED A COMPLAINT WITH THE GOVERNMENT SEVERAL YEARS AGO ABOUT THIS ISSUE AND I AM SURE MANY OTHERS HAVE AS WELL. NOTHING HAS...

THE SERVICE ENGINE LIGHT AND TRACTION CONTROL TURN ON AND THE INFORMATION CENTER ON MY CLUSTER READS "ENGINE POWER REDUCED" AND "STABILITY SYSTEM DISABLE", THEN MY SPEED IS REDUCED AND ONLY RUNS BETWEEN TEN AND TWENTY MILES PER HOUR. I HAVE TO TURN OFF MY TRUCK AND TURN IT BACK ON AFTER A FEW MINUTES TO CONTINUE, BUT THIS PROBLEM HAS HAPPENED ON A DAILY BASIS. I THINK GMC IS RESPONSIBLE FOR THIS AND MORE SIMILAR PROBLEMS. *TR

I HAVE HAD MULTIPLE ONGOING ELECTRICAL ISSUES WITH THIS VEHICLE. STARTING IN 2005, THE EXTERIOR ELECTRONICS (I.E. SIGNAL LIGHTS, STOP LIGHTS, HEAD LIGHTS, ETC) BEGAN TO MALFUNCTION. FOR EXAMPLE, I WOULD TRIGGER THE SIGNAL FOR ONE DIRECTION AND ALL OF THE SIGNALS FOR ALL DIRECTIONS WOULD TRIGGER... EVEN PRESSING THE BRAKES TRIGGERED ALL OF THE EXTERIOR SIGNALS. THE DEALER HAD A HARD TIME ISOLATING MY PROBLEM, BUT AFTER SEVERAL VISITS, THE DEALER WAS FINALLY ABLE TO DIAGNOSE AND RECTIFY IT... THEY ISOLATED IT TO A JUNCTION BOX WHERE ALL OF THE ELECTRONICS TERMINATE. HOWEVER, BY THIS TIME, MY VEHICLE WAS OUT OF WARRANTY, SO I HAD TO COVER THE COSTS FOR REPAIRING THE PROBLEM MYSELF. MY MOST RECENT ISSUES, WHICH, BY THE WAY, SEEM TO BE COMMON ISSUES, ARE TRIGGERED BY A MESSAGE STATING, "REDUCED ENGINE POWER". THIS PARTICULAR ISSUE DOES NOT ALWAYS RENDER THE SAME RESULTS... SOMETIMES THE VEHICLE'S...
