WE HAVE A 2003 YUKON THAT WILL SHUTS DOWN ANYWHERE AND ANYTIME, THE FOLLOWING EXAMPLE HAS HAPPENED MORE THAN ONCE. WE WERE DRIVING ON THE HIGHWAY WHEN "REDUCED ENGINE POWER" "STABILITY TRACTION LOSS" APPEARED ON DISPLAY - I PRESSED THE ACCELERATOR AND THE VEHICLE WOULD NOT MOVE. I HAD TO COMPLETELY SHUT DOWN THE ENGINE WAIT A FEW MINUTES THEN RESTART IN ORDER FOR THE VEHICLE TO OPERATE CORRECTLY AND A COUPLE MILES DOWN THE ROAD, IT HAPPENED AGAIN. IT WAS A SNOWY MESS OUT SIDE WHICH MADE THE SITUATION WORSE. THIS IS A MAJOR SAFETY CONCERN AS I AM UNABLE TO ACCELERATE IN ORDER TO AVOID AN ACCIDENT. I GET SCARED BECAUSE THERE COULD BE A SEMI BEHIND US AND IT WILL JUST PLOW INTO US BECAUSE WE CAN NOT DO ANYTHING UNTIL WE SHUT DOWN THE ENGINE AND RESTART. VERY SCARY. WE RESEARCHED THIS ISSUE TO FIND OTHER PEOPLE ARE IN THE SAME SITUATION AND NO ONE SEEMS TO KNOW HOW TO FIX IT. THIS IS A LONG STANDING ISSUE, GM IS AWARE OF THIS ISSUE BUT WILL NOT ISSUE A RECALL. GM SEEMS TO BE HAVING ALOT OF PROBLEMS THAT THEY ARE NOT DEALING WITH. SHAME ON GM! *TR

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 WAS DRIVING APPROXIMATELY 65 MPH UPHILL WHEN MY ENGINE AND TRACTION LIGHT CAME ON. MY SPEED WAS IMMEDIATELY REDUCED TO ABOUT 35 MPH EVEN THOUGH I TRIED TO ACCELERATE. I DROVE HOME ABOUT 8 MILES AT A REDUCED SPEED BECAUSE I HAD MY CHILDREN IN THE TRUCK AND IT WAS RAINING. I TOOK THE TRUCK TO A MECHANIC THE NEXT DAY AND HE REPLACED THE THROTTLE BODY. I PICKED UP THE TRUCK THAT EVENING AND AS I WAS DRIVING HOME THE SAME THING HAPPENED AGAIN. I TOOK THE TRUCK BACK TO THE MECHANIC, THE CHECK ENGINE LIGHT AND TC LIGHT WAS ON AGAIN HOWEVER HE SAID THAT THERE WAS NOTHING WRONG. HIS THOUGHT WAS TO REPLACE THE THROTTLE BODY AGAIN. TWO REPLACEMENTS LATER, THE PROBLEM REMAINS. *TR
