RE: FUEL TANK LEAK 2000 GMC YUKON/DENALI ON THE EVENING OF SEPTEMBER 23, 2004 THE FUEL TANK WAS FILLED AT A LOCAL GAS STATION. UPON ARRIVAL AT HOME A STRONG GASOLINE SMELL WAS NOTICED FROM THE VEHICLE. THE NEXT MORNING NO OVERWHELMING SMELL OF GASOLINE WAS EVIDENT. ON OCTOBER 1, 2004 THE FUEL TANK WAS FILLED DURING THE DAY, AND GASOLINE WAS OBSERVED LEAKING DOWN THE SIDE OF THE FUEL TANK AND DRIPPING ONTO THE GROUND. THE VEHICLE WAS DRIVEN HOME AND NOT USED UNTIL AFTER THE FUEL WAS NO LONGER LEAKING ON OCTOBER 4, 2004. THE VEHICLE WAS TAKEN TO A GMC DEALERSHIP, VINCE WHIBBS AUTOMOTIVE GROUP, IN PENSACOLA, FL FOR SERVICE ON OCTOBER 7, 2004. THE SERVICE CONSULTANT, CHRISTA HALL, CALLED LATER THAT DAY TO INFORM ME THAT THE FUEL SENDING UNIT HAD STARTED TO SEPARATE FROM THE FUEL TANK AND THAT IS WHERE THE FUEL LEAK HAD COME FROM. I WENT TO THE DEALERSHIP AND THE SERVICE TECHNICIAN, ALEX JENKINS, JR, SHOWED ME THE FUEL TANK THAT HAD BEEN REMOVED AND POINTED OUT WHERE THE LEAK WAS COMING FROM. IT WAS ALONG A BONDED/PLASTIC WELDED BEAD AROUND THE BASE OF THE FUEL SENDING UNIT AND WHERE IT JOINS THE PLASTIC FUEL TANK, LOCATED AT THE TOP CENTER. A NEW FUEL TANK HAD TO BE ORDERED TO REPLACE THE DEFECTIVE TANK. THE OLD FUEL TANK IS AVAILABLE. *NM

I'VE EXPERIENCED A VERY SERIOUS/DANGEROUS PROBLEM ON 9/5/03, 11/1/03, 11/2/03 & 4/18/04: THE ENGINE HAS COMPLETELY SHUT DOWN WHILE I WAS DRIVING MY SUV. THIS HAS HAPPENED WHILE I'VE BEEN DRIVING ON HWY, ON BRIDGES/ TUNNELS (WITHH NO SHOULDERS), & WHEN I'VE STOPPED THE SUV @ TRAFFIC LIGHTS & STOP SIGNS. THE COMMON DENOMINATORS FOR THE ENGINE SHUTTING DOWN SEEM TO BE: (1)LONG DISTANCE TRAVEL-ON ALL 4 OCCASIONS I HAD BEEN DRIVING THE VEHICLE ON THE HWY FOR 100 OR MORE MILES @ SPEEDS OF 60-70 MPH BEFORE THE ENGINE WOULD BEGIN SHUTTING DOWN (2)WEATHER- ON ALL 4 OCCASIONS, THE TEMPERATURE WAS 75-85 DEGREES WHEN THE ENGINE WOULD BEGIN SHUTTING DOWN WHAT TYPICALLY HAPPENS WHEN THE ENGINE SHUTS DOWN: WHILE ACTIVELY DEPRESSING THE ACCELERATOR PEDAL, I WOULD SUDDENLY NOTICE THAT I WAS NO LONGER GETTING ANY ACCELERATION POWER I WOULD THEN BEGIN TO PUMP THE ACCELERATOR PEDAL TO NO AVAIL ALL THE LIGHTS ON THE DASHBOARD ILLUMINATED, SIGNALING THE ENGINE SHUT DOWN WHEN POSSIBLE, I WOULD PULL OVER TO THE SHOULDER, & CRANK THE IGNITION 1-3 TIMES BEFORE THE ENGINE WOULD START AGAIN. ON THE DAYS THAT I EXPERIENCED THE PROBLEM, THE ENGINE WOULD CONTIN. TO SHUT DOWN EVERY 1-5 MILES, (MORE FREQUENTLY IN TRAFFIC). THE ENGINE WOULD CONTIN. TO SHUT DOWN UNTIL I COULD REACH A SAFE DESTINATION & ALLOW THE SUV TO REST FOR SEVERAL HRS. IN TOTAL, THE ENGINE SHUT DOWN 10-18 TIMES ON EACH OF THE 4 DAYS THAT I HAD THE PROBLEM. THE ENGINE WOULD SHUT DOWN MOSTLY WHILE I WAS ACTIVELY ACCELERATING, BUT ALSO HAPPENED FREQUENTLY WHEN I WOULD BRAKE WHILE IN TRAFFIC, & WHEN I WAS STOPPED @ A TRAFFIC LIGHT/STOP SIGN; OCCASIONALLY, THERE WERE TIMES WHEN I LOST ALL ACCELERATION POWER WHILE ACTIVELY DRIVING THE VEHICLE, BUT THE ENGINE DIDN'T ACTUALLY SHUTDOWN. AFTER 10-20 SEC. OF HAVING NO ACCELERATION POWER, I COULD SUDDENLY ACCELERATE AGAIN. WHEN THE ENGINE SHUT DOWN, THERE WERE NO SIGNS OF OVERHEATING & I HAD AT LEAST 1/3 TANK OF GAS.

BRAKES ON GMC DENALI VIBRATE AT 30 TO 45 MPH HAS HAVE THE ROTORS TURNED AND CUT TWICE SINCE THE CAR WAS PURCHASED IN AUG 2002 THE FIRST TIME WAS LESS THN 90 DAYS AFTER THE CAR WAS PURCHASE HAD LESS THAN 4000 ADDITIONAL MILEAGE. THE NEXT TIME WAS MARCH 2003 AGAIN LESS THAN 4K IN ADDITIONAL MILEAGE. AND JUNE 2003 THE SAME THING IS HAPPENING.*AK
