ABOUT A MONTH A AGO MY 2003 YUKON XL ALL OF A SUDDEN WOULD NOT DRIVE OVER15 MILES AN HR IN RUSH HOUR TRAFFIC. I TOOK THE TRUCK TO THE SHOP TO HAVE DIAGNOSTICS RAN. I WAS TOLD IT WAS THE BATTERY.

WE WERE DRIVING UP IN THE MOUNTAINS AND WE LOST POWER BRIEFLY TO THE ENGINE. THE LIGHTS FLICKERED AND THE DASH BOARD WENT OUT. THEN THE LOSS OF ENGINE POWER CAME ON AND THE STABILITY/TRACTION CAME ON TOO. THIS HAS HAPPENED WEEKLY FOR THE LAST TWO YEARS. THIS LAST TIME WAS ALARMING SINCE WE WERE COMING DOWN A MOUNTAIN IN A STORM AND COULD HAVE BEEN STRANDED UP THERE WITH NO RUNNING VEHICLE TO KEEP US WARM. THIS NEEDS TO GET A RECALL OR INVESTIGATION GOING ON THESE VEHICLES. IF YOU GOOGLE THIS ISSUE YOU WILL SEE THAT THERE ARE HUNDREDS IF NOT THOUSANDS OF PEOPLE THAT ARE AFFECTED WITH THIS ISSUE. IT WILL KILL PEOPLE IF THEY EXPECT TO HAVE POWER TO GET THROUGH AN INTERSECTION FAST ENOUGH AND THE VEHICLE GIVES OUT ON THEM. *TR

I WAS TRAVELING ON A TWO LANE COUNTY ROAD LOCATED IN OLDHAM COUNTY KENTUCKY AND UPON APPROACHING A CURVE, I ATTEMPTED TO APPLY THE BRAKE TO SLOW THE VEHICLE BUT THE BRAKE PEDAL WENT TO THE FLOOR AND PROVIDED NO BRAKING ACTION (SEVERELY RUSTED BRAKE LINES BURST AND RESULTED IN TOTAL BRAKE FAILURE ). THE CURVE WAS FOLLOWED BY AN INTERSECTION WITH A STOP SIGN IN MY LANE. LUCKILY THERE WERE NO VEHICLES IN FRONT OF ME AND NO OPPOSING TRAFFIC AT THAT MOMENT, WHICH ENABLED ME, THROUGH THE USE OF GEARS AND THE EMERGENCY BRAKE, TO GET THE VEHICLE STOPPED JUST BEYOND THE STOP SIGN. IT WAS MY UNDERSTANDING THAT MODERN VEHICLES WERE DESIGNED WITH REDUNDANCY IN THE BRAKING SYSTEM WHICH WOULD PREVENT TOTAL BRAKING FAILURE, BUT APPARENTLY THAT IS NOT TRUE WITH THIS VEHICLE. I HAVE READ SEVERAL ACCOUNTS OF SIMILAR FAILURES WITH THIS FAMILY OF VEHICLES AND I THINK ACTION NEEDS TO BE TAKEN QUICKLY AS THE NEXT VICTIM MAY NOT BE AS FORTUNATE AS ME AND MY 10 YEAR OLD GRANDDAUGHTER WERE THIS PAST WEEK. *TR

FOR THE LAST 2 YEARS I'VE HAD A PROBLEM WITH THE STABILITY CONTROL / REDUCED ENGINE POWER. THE PROBLEM CAN OCCUR ANYTIME WHILE DRIVING OR EVEN AFTER IT HAS BEEN SITTING. I MUST STOP THE VEHICLE AND TURN IT OFF SEVERAL TIMES FOR IT TO RESET BEFORE I CAN CONTINUE. I'VE HAD THE VEHICLE IN THE SHOP FOR REPAIRS AT THE DEALER, THEY CAN'T SEEM TO FIX THE PROBLEM. AFTER SEVERAL VISITS TO REPAIR SHOPS AND SPENDING NEARLY $2000 ON REPAIRS IT STILL HAS THE SAME PROBLEM. THIS NEEDS TO ADDRESSED AS A FAILURE AND DANGEROUS SITUATION BY G.M. THE VEHICLE IS A 2003 GMC YUKON DENALI XL. *LN
