2004 GMC Envoy Xuv Engine Problems

2004 ENVOY XUV, IMPECCABLY MAINTAINED, CAR WAS PARKED IN MY DRIVE WAY AND I STARTED IT TO GO TO THE STORE AND IT STARTED CHUGGING AND THEN ALMOST DIED, BUT THEN WENT BACK TO NORMAL BUT THE SERVICE ENGINE SOON AND REDUCED ENGINE POWER LIGHTS ILLUMINATED ON DASH.TURNED OFF ENGINE. RESTARTED, AND THE SERVICE ENGINE SOON LIGHT WAS STILL THERE SO MY HUSBAND HOOKED UP HIS CODE READER AND IT HAD THE CODE P1680 ( THROTTLE BODY POSTIONING CENSOR.) AND THIS ISN'T THE FIRST TIME IT'S DONE IT BUT THE ENGINE LIGHT HAS ALWAYS JUST FLASHED IT WOULD NEVER STAY ON SO WE COULD READ THE CODE. BUT IN ORDER TO FIX THIS YOU HAVE TO BUY A WHOLE NEW THROTTLE BODY HOUSING BECAUSE THE CENSOR IS BUILT INTO IT. AND IT ISN'T CHEAP. AT AUTOZONE IT IS $280.00. AND YOU HAVE TO ALSO BUY A GASKET FOR IT AND NEW INTAKE MANIFOLD GASKETS BECAUSE TO REMOVE THE THROTTLE BODY HOUSING WHICH IS CONNECTED TO THE MANIFOLD YOU HAVE YO REMOVE THE MANIFOLD ALSO. HOW IN THE WORLD DOES GM EXPECT US TO BE ABLE TO FIX THIS ISSUE IF IT'S ALWAYS SO MUCH MONEY FOR PARTS FOR THESE CARS. AND I ALSO HAVE ISSUES WITH MY BACK TAILGATE AND BOTH BIG WINDOW MOTORS. I HAVE REPLACED ONE BUT STILL SAVING UP TO REPLACE THE MIDDLE ONE AND I'VE ALSO HAD ISSUES WITH MY GAS TANK WHICH IS $677.00 OR MORE AT THE DEALERS FOR A NEW GAS TANK BECAUSE U CAN'T JUST FIX THE FILLER HOSE. SUCH FAILURES WILL EVENTUALLY KILL SOMEONE. SO I THINK GMC NEEDS TO TAKE A LONGER LOOK AT THESE GMC ENVOY XUVS AND GET SOME RECALLS OUT TO FIX THESE DANGEROUS PROBLEMS. AND HONOR ALL CARS THAT COME IN NO MATTER WHAT. BECAUSE WE HAD TO FIX THE GAS TANK ISSUE OURSELVES BECAUSE WE COULD NOT AFFORD TO BUY A NEW GAS TANK.

MY CAR OVERHEATED ON A NORMAL DAY, ABOUT 80 DEGREES OUTSIDE. I CHECKED AND REPLACED A DEFECTIVE THERMOSTAT, AND STARTED THE ENGINE ONLY TO FIND IT MISFIRING BADLY FOR THE FIRST TIME. I GAINED ADVISE FROM A LOCAL AUTO STORE AND CHANGED MY SPARK PLUGS. WHEN I PULLED OUT THE OLD ONES, I FOUND THREE OF THE SIX COVERED IN OIL. UPON FURTHER RESEARCH, I WAS INSTRUCTED TO REMOVE THE MANIFOLD AND REPLACE THE TUBE SEALS BUT THE PLASTIC MANIFOLD COVER WOULD NOT COME OFF AS INDICATED IN A GM MECHANICS MANUAL. THIS IS THE LAST OF SEVERAL PROBLEMS I'VE HAD WITH THE 2004 GMC ENVOY XUV 2WD INLINE 6. I SEE MANY COMPLAINTS ON THE OILY SPARK PLUG ISSUE AND CRACKED MANIFOLD BUT NO TSBS. LAST YEAR, I HAD MY A/C COMPRESSOR GO OUT AND REPLACED, MY GAS TANK LEAK AND REPLACED UNDER A 'SPECIAL WARRANTY', A DIAGNOSIS THAT MY HEATER CORE IS BAD, ALL THREE MOTOR MOUNTS GO OUT AND REPLACED, AND A NUMBER OF VARIOUS SMALL ELECTRONIC COMPONENTS GO OUT. I NEED GMC TO CORRECT THESE ISSUES OUTSTANDING WITH MY VEHICLE AND EXPECT APPROPRIATE ACTION FROM THEM. I SPENT WELL OVER $40000 FOR THIS VEHICLE AND ITS NOT EVEN 10 YEARS OLD YET. GM HAS BEEN WELL KNOWN FOR LONG LIFE OF THEIR ENGINES AND BODY FRAMES, AND HAVE SAID SO ON THEIR BEHALF. THEY NEED TO LIVE UP TO THE REPUTATION I HAVE SO LOYALLY PAINTED FOR THEM. *TR

2004 ENVOY XUV, IMPECCABLY MAINTAINED, HAD *NO* RESPONSE TO ACCELERATOR AS I MADE A LEFT TURN AT A LIGHT ACROSS ONCOMING TRAFFIC. SERVICE ENGINE SOON AND REDUCED ENGINE POWER LIGHTS ILLUMINATED ON DASH. WAS FORTUNATE NOT TO HAVE AN ACCIDENT. PULLED TO SIDE OF ROAD. TURNED OFF ENGINE. RESTARTED, AND IT RAN OKAY BUT THE SERVICE ENGINE SOON LIGHT REAPPEARED. DROVE ANOTHER 35 MILES WITH LIGHT ON. THE NEXT MORNING IT HAD RE-SET AND THE LIGHT IS GONE FROM THE DASH. HOW IN THE WORLD DOES GM EXPECT US TO BE ABLE TO REPLICATE SUCH INCIDENTS FOR A TECH TO FIX? SUCH FAILURES WILL EVENTUALLY KILL SOMEONE. *TR

I PURCHASED A 2004 GMC ENVOY XUV AND HAVE SEVERAL SIGNIFICANT PROBLEMS WITH THIS VEHICLE. AFTER RESEARCHING IT SEEM OTHERS HAVE HAD THE SAME TROUBLES. SINCE WE OWNED THE VEHICLE, THE REAR WINDOW IS FOUND DOWN AND NOONE WAS EVEN IN/NEAR THE VEHICLE. IT CONTINUES TO WORK BUT STILL WILL GO DOWN BY ITSELF. A YEAR AGO I HAD TO REPLACE THE FUEL TANK, THIS WAS RIGHT AFTER WE TOOK IT IN FOR INSPECTION ON A RECALL OF SMELLING GAS FUMES WHILE DRIVING AND POSSIBLE CORROSION IN FUEL LINES. OF COURSE THE FUEL LINES WERE NOT CORRODED SO WE WERE TOLD. I FOOTED THE BILL $800+ TO GET A NEW FUEL TANK ,AS NECK ON TANK WAS CRACKED AND WAS TOLD THAT THIS IS WHY WE SMELLED GAS. LUCKILY, I WENT TO MY GARAGE AND SAVED SEVERAL HUNDRED DOLLARS FROM THE DEALERS COST TO REPAIR. LAST WEEKEND 9/10/10 MY FAMILY WAS DRIVING TO TOWN AND THE MIDDLE WINDOW UNEXPECTEDLY DROPPED AND NOW DOES NOT WORK. I RESEARCHED AN IT SEEMS TO BE A REGULATOR ISSUE AND WILL COST AROUND $500, WOW! OVER THE LAST TWO WEEKS THERE IS A RATTLE WHEN WE TURN ON OUR AC. AGAIN AFTER WE WERE IN FOR SERVICE AS WE HAD THE AC CHARGED AT THE START OF SUMMER. I CAN SEE WHERE I HAVE THE SAME TROUBLES AS A LOT OF OTHERS AND FEEL, THE SAME AS THEY DO, LEFT HOLDING THE BAG BY GMC AND NO WAY OUT BUT, TO LOOK FOR A NEW/USED VEHICLE AND GET RID OF THIS VEHICLE. *TR

GMC WON'T FIX IT UNLESS I GIVE THEM ABOUT $1,000.00. EXHAUST MANIFOLDS ALMOST NEVER CRACKED IN THE PAST. PLEASE INSIST THEY HELP US LIKE WE HELPED THEM. *TR

I HAVE A 2004 SUV XLT. I BOUGHT MY CAR WITH 400 MILES ON IT. I HAD THE GAS TANK REPLACED EARLY ON. WENT BACK TO GMC B/C THEY HAD NOT INSTALLED IT PROPERLY. I'VE HAD BOTH FRONT AND REAR SWAY BARS REPLACED AND BOTH KNOCK SENSORS REPLACED. MY MIDDLE WINDOW DECIDED TO QUIT WORKING AND I HAVEN'T GOTTEN IT FIXED BECAUSE THE GUYS AT THE GMC SERVICE CENTER SAID THEY COULDN'T IMAGINE WHAT IT COULD BE AND THEY WOULD HAVE TO CHARGE ME $100 FOR A DIAGNOSIS!! MY RADIO/CD PLAYER IS ONLY HALF LIT UP AND STOPS WORKING WHEN IT GETS TOO HOT FROM PLAYING A CD... I AM CURRENTLY HAVING ISSUES WITH THE FAN CLUTCH, THERMOSTAT AND A LEAK IN MY FRONT DIFFERENTIAL. MEANWHILE THE GUYS AT THE DEALERSHIP WANTED TO CHARGE ME $1,500 TO REPLACE MY KNOCK SENSORS AGAIN AND DIDN'T EVEN FIND THE LEAK WHEN THEY WERE "DIAGNOSING" MY ISSUE. I TRULY DO LOVE MY CAR, BUT I AM SUPER MAD ABOUT THE MIDDLE WINDOW AND SUPER MAD ABOUT ALL OF THESE ISSUES. I TAKE CARE OF MY CAR AND DO ALL OF THE ROUTINE MAINTENANCES. I THINK I KNOW WHY IT WAS ONLY ON THE MARKET FOR TWO YEARS. PLEASE HELP US GET OUR MIDDLE WINDOWS FIXED. I DIDN'T DO ANYTHING TO CAUSE IT TO STOP WORKING. *TR

I PURCHASED A 2004 GMC ENVOY XUV PREOWNED IN 2005 STILL UNDER WARRANTY. IT BEGAN DIMMING THE LIGHTS IN THE DASH BOARD AND AT THE RADIO AREA, I TOOK IT IN TO GMC FOR SERVICE AND WAS TOLD THAT THEY DIDN'T FIND ANYTHING WRONG WITH MY VEHICLE. ON ANOTHER OCCASION MY CAR WOULD GET LOUDER UNDERNEATH THE HOOD IF I SAT IDLING FOR A FEW MINUTES IN A DRIVE THROUGH FOR EXAMPLE, I TOOK IT IN ONCE AGAIN AND WAS TOLD THAT IT WAS NORMAL NOTHING WAS FOUND TO BE WRONG. NOW MY ODOMETER WORKS OFF AND ON AS DOES MY OIL GAUGE. NOW THAT MY WARRANTY IS OUT I WOULD HAVE TO FOOT THE BILL TO A FEW PROBLEMS THAT I HAVE POINTED OUT TO THE GMC DEALER SHIP ON MORE THAN ONE OCCASION. I HAVE EVEN GONE AS FAR AS TO ASK IF THERE WERE ANY RECALLS AND WAS TOLD NO THERE WERE NOT. AT ONE POINT MY MIDDLE WINDOW FELL DOWN WHILE I WAS DRIVING I TOOK IT TO GMC TO FIND OUT THE PROBLEM AND WAS TOLD IT WAS THE REGULATOR, INSURANCE DID NOT COVER THIS AND THE WARRANTY HAD RUN OUT. APPROXIMATELY 2-3 WEEKS LATER MY BACK WINDOW WOULD NOT GO UP OR DOWN THEREFORE THE TAILGATE WOULD NOT OPEN, BACK TO GMC I WENT AND WAS TOLD IT WAS THE REGULATOR ONCE AGAIN, AT THIS POINT I ASKED AGAIN ABOUT RECALLS AND WHY BOTH REGULATORS WOULD GO BAD WITHIN WEEKS OF ONE ANOTHER, I WAS TOLD IT WAS A COINCIDENCE. JUST AS RECENT AS JULY 24 MY POWER LOCKS BEGAN LOCKING AND UNLOCKING ON THERE OWN EVEN WHILE I'M DRIVING DOWN THE STREET. I HAD THE BATTERY CHECKED AND IT ALL CHECKED OUT FINE. AT THIS POINT I WOULD NOT RECOMMEND GMC TO ANYONE OR BUY ANOTHER! HELP *TR

MY ENVOY XUV (8CYL) HAS ENGINE TROUBLE, WHICH GMC SAYS IS NORMAL. IT OCCASIONALLY HAS EXTREMELY ROUGH IDLE, MORE TIMES THAN NOT, IT HESITATES AS IF TRYING TO DECIDE IF IT'LL STALL OUT OR NOT. USUALLY THIS HAPPENS WHEN ATTEMPTING TO RESUME DRIVING AFTER SITTING AT A LIGHT OR AFTER OTHER COMPLETE STOP. I FEEL THAT THIS ONE DAY MAY GET ME REAR ENDED OR T-BONED BY ANOTHER CAR. SADLY, I NOTICED THIS SINCE THE FIRST DAY I DROVE IT OFF THE LOT BRAND NEW.*AK
