There are 15 owner-reported powertrain & transmission complaints for the 2005 GMC Envoyin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
All the gages have stopped working correctly. They do not report proper information to driver . The electrical wiring to the rear wiper, license plate lights and rear hatch stopped working. The most dangerous thing is the ABS brake system dash lights and bell comes on every time the car is driven and the brake pedal goes to the floor when trying to stop.
MY VEHICLE WHEN PURCHASED WAS ALTERED FROM CLOTH SEATS TO LEATHER BY THE DEALERSHIP WHERE PURCHASED. 3 DAYS AGO MY CAR IS SIGNALING ME TO SERVICE AIRBAG WHILE DRIVING THE CAR OR IN IDLE. SO I IMMEDIATELY TOOK IT TO A CERTIFIED MECHANIC AT MEINEKE AND WAS TOLD THAT THIS IS A MANUFACTURER DEFECT AND THERE IS A RECALL FOR THIS ON MY YEAR, MAKE & MODEL SUV. I CALLED GM ON 11/29/2019 AND WAS TOLD BY A SUPERVISOR NAMED ANGEL THERE HAS BEEN NO RECALLS BY THEIR MANUFACTURER AND THERE IS NOTHING MORE SHE CAN DO ABOUT THE MATTER. I CANNOT DRIVE MY CAR LIKE THIS KNOWING THIS CAN BE POTENTIALLY HARMFUL AND HAZARDOUS.
MY PASSENGER WINDOW WON'T WORK!
I WAS DRIVING ABOUT 25 MILES PER HOUR @ NIGHT WHEN ALL THE WARNING LIGHTS ON THE DASH CAME ON AND ALL THE GAUGES READ ZERO EXCEPT THE SPEEDOMETER AND TACH, TRANSMISSION GEAR SELECTOR WASN'T INDICATING WHAT GEAR I WAS IN & RADIO ALSO KILLED. HEADLIGHTS, WIPERS & DIRECTIONS WERE STILL FUNCTIONAL. I ONLY HAD A MILE TO DRIVE TO GET HOME. PARKED VEHICLE IN GARAGE AND SHUT OFF....ONLY TO DISCOVER THAT POWER LOCKS HAD FAILED AND I WAS LOCKED IN CAR, POWER WINDOWS WERE ALSO OUT! REMOVED KEY FROM IGNITION AND FORTUNATELY THE REMOTE KEY FOB UNLOCKED THE DOOR. HAD THIS BEEN AN EMERGENCY SITUATION, I WOULD HAVE NO WAY TO EXIT THE CAR NOR WOULD ANY PASSENGERS. ANYONE ELSE HAVING THIS PROBLEM? I CONTACTED DEALER TO APPRIZE THEM OF THIS NEW PROBLEM AND WAS ADVISED THAT IF IT'S INTERMITTENT THEY WOULD HAVE PROBLEMS FIXING IT. THE VEHICLE SEEMED TO RESET IN THE MORNING AND ALL DASH WARNING LIGHTS BACK TO NORMAL! *TR

I WAS DRIVING MY CAR AND LOST THE DRIVE GEAR AND HAD TO DOWN SHIFT TO 2ND GEAR ALTHOUGH I OWNED AN AUTOMATIC CAR. I ONLY HAD A CAR WITH 50,000 MILES ON IT. I COULDN'T BELIEVE IT COULD BE MY TRANSMISSION ALREADY. I WAS ABLE TO UP SHIFT TO DRIVE BUT ONLY AFTER GOING INTO 2. WHEN I ARRIVED AT MY UNCLES HOUSE, HE SAID THE TRANSMISSION WAS LIKELY GONE. *TR
I HAVE A 2005 GMC ENVOY. I AM HAVING PROBLEMS WITH MY SHIFT LEVER; IT GOES IN PARK AND STAYS THERE FOR ABOUT THREE MINUTES BEFORE IT RELEASES THE KEY (TO BE TAKEN OUT OF THE IGNITION). WHEN I START THE TRUCK, IT WILL NOT GO INTO ANY GEAR FOR ABOUT THREE MINUTES, THEN I HEAR A CLICK WHICH THEN RELEASE THE SHIFT SO IT CAN BE MOVED INTO ANOTHER GEAR. IT BEGAN ABOUT TWO MONTHS AGO AND HAS GOTTEN WORST OVER TIME. ONCE IN ANY GEAR ACCEPT PARK IT CAN BE SHIFTED TO ANOTHER GEAR WITHOUT ANY STRAIN. THE CONSEQUENCE OF THIS PROBLEM IS NOT BEING ABLE TO GET OUT THE VEHICLE WITH MY KEY ONCE IN PARK UNTIL AFTER THE LEVER CABLE "SNAPS IN PLACE." I HAVE NOT BEEN ABLE TO DO MUCH OF ANYTHING ABOUT IT THUS FAR DUE TO FINANCIAL DIFFICULTIES. *TR
TL*THE CONTACT OWNS A 2005 GMC ENVOY. WHILE DRIVING 75 MPH IN THE RAIN WITH THE CRUISE CONTROL ACTIVATED, THE VEHICLE BEGAN TO DECELERATE ON ITS OWN. IN ADDITION, THE ENGINE BEGAN TO REV.

THE VEHICLE WAS TOWED TO THE DEALER AND THEY STATED THAT THE TRANSMISSION WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE VEHICLE HAS NOT BEEN REPAIRED.

TRANSMISSION FAILURE, MECHANIC CAN NOT FIND WHAT THE CAUSE IS FROM, GMAC SENT A TECHNICAL SERVICE BULLETIN TO THE MECHANIC THAT STATES THIS PROBLEM HAS BEEN SEEN WITH THESE VEHICLES, NO GUARANTEE IT WILL NOT HAPPEN AGAIN. *TR
MY 2005 GMC ENVOY CONTINUES TO HAVE THE SAME PROBLEM OVER AND OVER. I'M TAKING IT IN AGAIN TODAY FOR THE 4TH TIME. IT LOSES POWER GOING UP HILLS. IT'S LIKE THE ENGINE IS STALLING, AND IT HAS ACTUALLY CUT OFF ON ME. THE FIRST 2 TIMES THEY COULD FIND NOTHING WRONG. SO IT DIDN'T GET FIXED. THE 3RD TIME THE CHECK ENGINE LIGHT FINALLY CAME ON. THEY SAID IT WAS THE OXYGEN SENSOR, AND CARBON BUILD UP ON THE FUEL SOLENOID. ONCE AGAIN THE CHECK ENGINE LIGHT IS ON. THIS TIME I HAD ONSTAR DO A DIAGNOSTIC TEST. I WAS INFORMED THAT THERE IS A POWER TRAIN SYSTEM MALFUNCTION. WHICH IS THE PART OF THE ENGINE SYSTEM THAT PROVIDES POWER TO MOVE THE VEHICLE. OBVIOUSLY THIS HAS BEEN THE PROBLEM ALL ALONG THAT THE DEALERSHIP CAN NOT SEEM TO FIX. OF COURSE THE GAS MILEAGE IS TERRIBLE DUE TO THIS SITUATION, AND WITH GAS PRICES THE WAY THEY ARE IT'S KILLING ME. *JB
TL*- THE CONTACT STATED THAT WHILE DRIVING THE 2005 GMC ENVOY WITH 32000 FAILURE MILEAGE AT 35 MPH ON MANY DIFFERENT OCCASIONS THE VEHICLE SWITCHED INTO 4 WHEEL DRIVE ON ITS OWN AND SLOWED THE VEHICLE DOWN IN THE PROCESS. THE CONTACT KEPT CONTROL OF THE VEHICLE AND PULLED IT ONTO THE SIDE OF THE ROAD. THE VEHICLE WAS TOWED AND REPAIRED ON SEVERAL OCCASIONS, BUT NOTHING SEEMED TO RESOLVE THE PROBLEM. THE CURRENT MILEAGE WAS 41000.*AK
WE PURCHASED OUR 2005 GMC ENVOY SLT IN DEC. 2004, WHICH CAME RIGHT OFF THE SHOWROOM FLOOR. WE HAD LOW FUEL ECONOMY BUT THOUGHT THIS WOULD GET BETTER WITH MORE MILES. AFTER 30,000 MILES OUR TRANSMISSION WENT OUT WITHOUT WARNING. AT NO TIME DID ANY INTERNAL SENSOR SYSTEM DETECT A PROBLEM AND WE DID NOT NOTICE ANYTHING UNTIL IT WAS TO LATE. WE TOOK IT BACK TO DEALER AND LUCKILY IT WAS COVERED UNDER WARRANTY FOR REPAIR. ACCORDING TO MECHANIC THE PROBLEM WAS A SMALL O-RING WHICH WAS DAMAGED AT THE FACTORY AND THAT THE TRANSMISSION CAME FROM THE FACTORY THIS WAY. THEY DID REBUILD THE TRANSMISSION BUT NOW I ONLY HAVE A 12,000 MILE WARRANTY ON A REBUILT TRANSMISSION. WE FEEL THIS IS UNFAIR AS THE TRANSMISSION WAS DAMAGED AT THE FACTORY AND WAS NOT CAUSED BY ANYTHING WE DID. WE PAID A HEFTY SUM FOR THIS SUV AND NOW THE VALUE HAS DEPRECIATED EVEN MORE BECAUSE OF THIS PROBLEM. NOW WE FEEL WE HAVE A LEMON ON OUR HANDS AND NO WAY TO REMEDY THE SITUATION, NOT TO MENTION THE GAS WE WASTED AND THE TIME IT WAS IN THE SHOP FOR APPROX. 2 WEEKS. WE THOUGHT WE WERE GETTING A RELIABLE VEHICLE!!! *JB
CAR SWITCHES INTO ALL 4W AND HIGHER BY ITSELF. I HAD BEEN TO A DEALERSHIP 3 TIMES IN ONE YEAR FOR WHICH THEY WERE UNABLE TO FIND THE PROBLEM. NOW MY WARRANTY IS UP. AFTER THAT I TOOK IT TO A TRANSMISSION SHOP WHERE THEY SUPPOSEDLY FIXED THE PROBLEM FOR OVER 800.$ A WEEK LATER IT DID IT AGAIN. NOW I HAVE THE 4WD DISCONNECTED FOR SAFETY REASONS. I WOULD BE DRIVING ON THE FREEWAY AT 60-75 MPH AND IF WOULD SWITCH AND NOT COME OUT NO MATTER WHAT I DO. I HAVE OWNED THIS VEHICLE FOR ALMOST 5 YEARS AND IT HAS DONE THIS THE WHOLE TIME. I AM A SINGLE MOM AND I DRIVE MY 17 AND 7 YEAR OLD AROUND IN THIS CAR. EVEN WITH IT DISCONNECTED IT STILL TRIES TO SWITCH. THERE IS NO SPECIFIC TIME, TEMPERATURE, OR OTHER REASON THIS HAPPENS. IT HAS HAPPENED WHEN I TURN ON THE CAR AND SOMETIMES I CAN GO A COUPLE OF WEEKS AND OTHER TIMES IT HAPPENS DAILY. I ALSO HAVE HAD MY LIGHTS NOT GO ON FOR NO REASON AND ALSO THE DOORS LOCK AND CAN ONLY BE UNLOCKED BY USING THE KEY. AND THE HATCHBACK WILL NOT OPEN AT ALL WHEN THIS HAPPENS. ELECTRICAL?? HELP!! *TR
