2004 GMC Envoy fuel/propulsion system problems

“I JUST HAD MY BRAKES SERVICED AND MY BUSHINGS CHANGED, BUT MY ABS LIGHT STILL COMES ON. ALSO WHEN I GO TO BRAKE THE CAR STARTS TO SHAKE AND I'M GOING THE SPEED LIMIT. THE ENGINE HAS A ROUGH IDLE, AND SHUTS OFF WHEN AT A COMPLETE STOP AND WHEN THE VEHICLE IS IN MOTION. I'VE HAD MANY THINGS REPLACED ON THE VEHICLE, SUCH AS PURGE VALVE, GAS CAP. CHARCOAL CANISTER AND FUEL TANK. IN THE ENGINE THE SPARK PLUGS WERE CHANGED AS WELL AS THE COIL PACKS AND THE FUEL INJECTORS. ALONG WITH THE CAMSHAFT SENSOR. STILL GETTING P0455 AND PO0014. WON'T PASS SMOG CAN'T REGISTER VEHICLE, BUT MY ONLY MEANS OF TRANSPORTATION. 2004 GMC ENVOY XUV SLT 4DR 2WD”

“THE TRANSMISSION STARTED TO SLIP, NOTICED IT STARTING TO HAVE ISSUES GETTING UP TO PROPER SPEED WITHOUT SLIPPING AND TRYING TO STALL, AND WAS TOLD BY PREVIOUS OWNER WHOM I'M PURCHASING IT FROM THAT THERE IS A POSSIBLE ISSUE WITH THE TRANSFER CASE AS WELL, AS IT ENGAGES IT'S 4 WHEEL DRIVE WITHOUT ME TOUCHING IT, TRIED TO SERVICE THE TRANSMISSION AND PUT FRESH FLUID AND A NEW FILTER IN TO SEE IF IT WOULD HELP AND NOW IT CAN ONLY GO AS FAST AS 40 TO 55 BEFORE IT STARTS TO SLIP PRETTY BAD. I HAVE A BABY ON THE WAY DUE IN THE NEXT COUPLE WEEKS AND WITH IT SLIPPING AND DROPPING SPEED IT CAN CAUSE ME TO END UP GETTING HIT AND I DON'T WANT TO PUT MINE, MY CHILD, OR ANY OF MY OTHER PASSENGERS IN DANGER.”

“WHILE DRIVING ON THE STREET ON MY WAY HOME FROM WORK , I COULD SMELL GAS... GOT OUT AND SAW A VISIBLE LEAK COMING FROM THE GAS TANK.. I PROCEEDED TO LOOK THIS PROBLEM UP, AND FOUND OUT THIS IS A REOCCURRING PROBLEM WITH THIS VEHICLE .”

“THE GAS TANK KEEPS CRACKING CAUSING GAS TO LEAK OUT. IT HAS BEEN IN THE SHOP TWICE FOR THIS AND CAR HOP ONLY WANTS TO CONTINUE TO PUT A USED TANK ON IT. THE SHOP REQUESTED A NEW TANK BE PURCHASED AND THEY DENIED TO REQUEST. THE FIRST TIME IT WAS IN THE SHOP THEY WEN THOUGH THREE TANKS THEN IT ONLY LASTED ABOUT A MONTH.”

“FUEL TANK. AT LEAST THREE YEARS AGO, I RECEIVED A RECALL FORM GM BECAUSE OF THE FUEL FILLER TUBE/FUEL TANK WAS COMPROMISED AND I WAS BEING RECALLED FOR A FUN TANK REPLACEMENT. WENT TO MY GMC DEALER (NALLEY OF BRUNSWICK GA) WHO TOLD ME THAT FUEL TANKS WERE ON NATIONAL BACKDOOR EVEN THOUGH THEY HAD THE FILLER TUBE PARTS, WOULD NOTIFY ME WHEN THE TANKS AVAILABLE. I FAITHFULLY REVISTEDTHEM EVERY 6 MONTHS TO BE TOLD SAME STORY, STILL NO FUEL TANKS. I BELIEVE NOW THEY ARE HOPING I JUST GO AWAY. IN THE MEAN TIME I STILL CANNOT FILL UP THE TANK WITHOUT HAVING GAS FUMES EMANATING FROM UNDER THE CAR.”

“LEAKS FUEL. COMMON PROBLEM FROM WHAT I AM READING ONLINE. WAS TOLD BY SERVICE TECH THAT FUEL TANK NEEDS TO BE REPLACED. PLASTIC TANK IS BROKEN WHERE FILL HOSE CONNECTS TO THE TANK INLET CHECK VALVE.”
