2003 GMC Yukon Xl 1500

I KEEP HAVING THE DISPLAY SAY "REDUCED ENGINE POWER". I'LL BE DRIVING ON THE HIGHWAY, DOING 65 IN RUSH HOUR TRAFFIC, WHEN ALL OF THE SUDDEN THE ACCELERATOR NO LONGER ACCELERATES AND IT DISPLAYS "REDUCED ENGINE POWER" ON THE GAUGE CLUSTER DISPLAY. FROM WHAT I'VE SEEN ONLINE IT APPEARS TO BE AN ISSUE WITH THE THROTTLE POSITION SENSOR ON THOUSANDS OF OTHER SIMILAR VEHICLES WITH THE SAME ENGINE, CHEVY SUBURBAN'S, SILVERADO'S, TAHOE'S, ETC. I REPLACED THE THROTTLE POSITION SENSOR AND THE HARNESS (BECAUSE I HEARD THE HARNESS MIGHT ALSO BE AN ISSUE) AND I AM STILL HAVING THE SAME PROBLEM WITH MY TRUCK. IT HAS DONE IT OVER A DOZEN TIMES ON ONE TRIP BACK FROM WORK (80 MILES FOR ME). I HAVE TO PULL OVER TO THE SIDE OF THE ROAD (IF POSSIBLE) AND TURN OFF THE TRUCK, THEN WAIT A SHORT PERIOD OF TIME, THEN TURN THE TRUCK BACK ON. THIS USUALLY FIXES THE ISSUE, BUT IT DID NOT HELP ME WHEN IT HAPPENED TO ME IN THE TUNNEL AND I WAS GOING 5 MPH (TOP SPEED DURING THE "REDUCED ENGINE POWER" MODE, ONCE YOUR DRIFTING STOPS (BECAUSE YOU DRIFT, IT DOESN'T ENGAGE THE BRAKES). I WAS EXTREMELY WORRIED THAT I WOULDN'T MAKE IT OUT OF THE TUNNEL WITHOUT GET REAR ENDED, AND ONCE I MADE IT OUT, I WAS JUST OUTSIDE OF THE TUNNEL AWAITING ROADSIDE ASSISTANCE, IT WAS VERY FRIGHTENING, WITH MY DAUGHTER IN THE CAR.

2003 YUKON XL REAR GLASS HINGE (DRIVER'S SIDE) FAILED WHILE DRIVING. HEARD WHISTLING SOUND, DIDN'T KNOW WHAT IT WAS, STOPPED AT HOME DEPOT AND REAR GLASS HATCH WOULDN'T CLOSE AFTER I'D OPENED IT. HINGE ITSELF APPEARS TO BE INTACT, JUST DEBONDED/DEWELDED FROM THE GLASS. GM WANTS $1100 TO REPLACE WITH A DIFFERENT WINDOW- THE ORIGINAL DESIGN LIKE THE ONE THAT FAILED HAS BEEN 'IMPROVED UPON' AND IS NO LONGER AVAILABLE. WHAT'S FUNNY IS THAT THERE'S A RECALL FOR SUBURBANS OF THE SAME YEAR, BUT NOT YUKON XLS EVEN THOUGH IT'S THE SAME PART... *TR
