Problems with 2005 GMC Envoy POWER TRAIN

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

Tl* the contact owns a 2005 gmc envoy. the contact stated that the vehicle failed to shut off and the heater fan continued to operate. the contact had to unplug the battery terminal in order to turn off the vehicle. in addition, the contact noticed that the fuse box was melted. the vehicle was taken to the dealer. the technician replaced the fuse box and other parts that were damaged; however, the failure persisted. the contact stated that the vehicle failed to start on the first attempt and the gear shift would not shift gears. the vehicle had not been repaired. the manufacturer was not notified of the failures. the failure mileage was unavailable.

6/13/2011 vehicle taken to gmc service for transmission flush and filter change. returning home same afternoon vehicle transmission started slipping and stopped moving. after repeated attempts to move vehicle it was towed to local dealership. service manager stated that probably broken hard parts inside the transmission were to blame. rebuild trans. in range of 2$k, replacement $3k. spoke with gmc customer service, no explanation why transmission failed or assist to replace transmission. this vehicle has 105,151 miles on odometer. *tr

Tl* the contact owns a 2005 gmc envoy. the contact was driving 30 mph when the vehicle stalled without warning and would not restart. the vehicle was then towed to a local mechanic who inspected the vehicle and informed the contact that the transmission needed to be replaced. the transmission was replaced at the contact's expense. a letter was sent to the manufacturer who in return, called the contact and offered no assistance. the failure mileage was 34,000. updated 07/08/11 *bf updated 07/18/11

The wipers were the first to go. that needed a control module. the touch pads for the tail gate were next. first the drop down then the swing. then the right side passenger door inside handle stopped working. then the left side rear door outside handle doesn't work. then the four wheel drive doesn't work. then the fuel gauge doesn't work. now the passenger's window doesn't open. 5th speed on the heater stopped working. what is the matter with gmc? that is a high end vehicle and as such should not be plagued with such problems. *kb

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 pulled over to the side of the road and turned off. when the contact restarted the vehicle and shifted into drive, it would not shift into third or fourth gear. 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. the manufacturer stated that they would call the dealer to find out the diagnosis of the failure and then call the contact. the current and failure mileages were 49,000. updated 01/08/09 *bf updated 01/09/09 *jb

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

Repeat problems since car was purchased brand new at dealers. air /o2 sensors defective/replaced. defective fuel pump/fuel sensor/electronic gas gauge; flickering/dimming headlights; freezing/inability to control driver's side seat and controls. 1/4 of front instrument panel lights out; drivers side seat control lighting 1/4 out; check engine light and low fuel light on continuously since 1997. tie rods both replaced as well as both front sway bars. immediately following vehicle purchase, check engine light would continuously go off. i would call onstar at which point i was told to take car in for repair w/i 7-10 days (often told a problem w/powertrain or transmission) . at dealers service dept, told over and over again after tons of worry, concern and time spent, that electrical system on this car tends to trip/trigger check engine light and they would just reset it so after awhile, i began to disregard the light as i was in the dealership almost weekly. approx 2 yrs after purchase, filled up gas tank and fuel light showed "low fuel". went back up to full, dropped to 1/2 and back to empty. went back to full after car was turned off and continued to do this. after about 2 weeks, constantly stays at empty. called repair shop and was told approx $700-800 to drop tank and replace fuel sensor which i could not afford and began to track odometer and refill tank after 200 miles driven after fill up. have been doing this for 5 years. jan 29,2011, i go for emission test. fail d/t low fuel and check engine light being on. go to mechanic, approx $950 repair. check engine light goes off...and back on next day. read thousands of posts online and am finding many, many envoy owners experiencing same problems as mine. these are safety issues and gm should issue a recall on entire fuel and electrical system. please call for questions/clarification. *tr

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

Tl*the contact owns a 2005 gmc envoy. the contact stated that the engine made a loud knocking noise when driving. while driving uphill, the vehicle dramatically decelerates as if the engine was stalling. the engine and oil lights illuminated on the instrument control panel. she took the vehicle to the dealer for an oil change, but the oil light remained illuminated. she took the vehicle to a local dealer four times and they reprogrammed the p.c. another dealer stated that the engine drags when traveling uphill, which was probably due to the clutch fans. the contact also stated that the air conditioning system does not work. after all four repairs were performed, her vehicle continues to experience the same failures. she contacted the manufacturer and they stated that they would not provide any financial assistance because the extended warranty expired. the speed was unknown. the failure mileage was 3,809 and current mileage was 82,000.
