I was driving home from the beach (sandy hook national park, nj) when my service engine soon light came on. I used on star to remote diagnose the code, and was told it was an error in my transmission control module. I immediately called my nearest service center who inspected my truck and informed me that it was my transmission lines that had just simply 'corroded' and that my transmission has almost been running on no fluid. This was shocking considering I maintain good care of my 2002 envoy and had seen no sign of leaking transmission fluid but was informed it was somehow all over the bottom of my truck. They were able to fix the lines for a cost of 690 dollars, but I still feel that something is not quite right with this situation and have talked to others with similar issues.
2002 GMC Envoy transmission complaints
Page 2 of 4: complaints 11 to 40 of 83, newest first, as owners wrote them.
Transmission cooler line leak from corrosion on 2002 gmc envoy. Had to do splice of corroded section and replaced with copper coupling.
Vehicle will not move when put in drive or reverse from park position. After switching from 4wd to 2hi etc. It sometimes will engage and move. If in fact the vehicle moves it hesitates when making deep turns. For the most part it is stuck in drive and reverse. Transfer case control module was a diagnosed problem by dealership in 2006. New part bought and installed by dealership.
After pulling away from a stop light at a normal pace and reaching a speed of almost 50mph there was a loud clunk and a rrrrr sound coming from under the vehicle. The vehicle began to slow as the RPM's went up, all forward drive was gone. We almost got rearended... There was no warning at all that there was a problem or was going to be a problem ,it just broke..dealer says need new transmission.. Apparently gm has a sun gear issue with this type of transmission..
My wife was driving our 2002 gmc envoy onto a local expressway when she tried to accelerate, she heard a loud noise from the engine/tranny area, then noticed high rpms and the transmission not shifting, she immediately pulled over. I came to her location and noticed loss of reverse and a "whine" coming from the transmission, the vehicle was towed to the local gmc dealer, that same day it was diagnosed as the sun shell. It appears that this is a common failure, I will be pursing this further with gm.
Roaring sound, no power, vehicle can barely reach 30mph, loud noise has existed for long time (several years) and the power problem usually resolved after about 5 minutes. This is a defect. I found hundreds of owners complaining of same problem on line. Dealer replaced fan clutch.
Tl*the contact owns a 2002 gmc envoy. The contact stated that while driving the vehicle it will randomly jump from 2 wheel drive to 4 wheel drive without warning causing the car to become idle and you must turn the car off completely. She took the vehicle into a local mechanic where he replaced the brakes and checked the wheels and stated that there was nothing wrong with the vehicle. She is also experiencing problems with the front passenger seat belt it locks when fastened. She took the car to the dealer and they informed her that it was no longer covered under warranty and any repairs made would be at the owner's expense. The vehicle is also experiencing exterior light failure, both headlights burned out within weeks apart and they were replaced at owner's expense. The failure mileage was 38,000. The current mileage was 86,000 (sc) updated 06/25/08. *cn the consumer also stated when driving past 70 MPH, the vehicle would shake. The windshield wipers were replaced. The consumer stated the motor failed. Updated 06/25/08
56,779 mile and transmission failed on my 2002 envoy. Dealer told me they had never saw this happen. We had just made a 2300 mile trip to the 'no man land' of colorado. The next day my wife came to a stop sign, said the car made a weird noise and would not go. No reverse or drive but crippled it home in low. Was very surprised that the gm dealer would not back the transmission. $2,903.94 to replace with a 1 year guarantee which is about up and I refuse to drive on a long trip again in this auto.
I was driving along interstate 75 at night with my 3 year old, 16 year old, and 18 year old nephew returning to college after winter break on jan. 2,003. We were left stranded on the side of the highway, after we almost wrecked. The gears were jumping back and forth from 2 wheel to wheel drive. I took to a local gm dealer and they told me that it would costs me 2500 to repair-the problem the front differential. I contacted the 1800 gm service line and they said that they would not be assisting with repairs due to mileage. I asked around at different auto repair and transmission shops and they said that gm knows they have a problem with the differential in envoys, trailblazers, and isuzus. Even if the problem gets fixed, im told there is no guarantee that the problem will not happen again until gm addresses the actual problem with the differentials. I believe my gear problem caused the differential to fail. Meanwhile I am stuck with a car that I have to pay for another year and a half on. It is really an inconvenience to me. I cannot afford the repair, the car sits in the driveway. Im behind on my car payment, having to rent a car to drive to work. Gm should be held accountable. Other problems include the clutch fan going out, costing me over $500 to repair on my own. Gm refused to help. This went out at 33,000, shortly after purchase. I am really burdened right now and don't know what to do.
Tl*the contact owns a 2002 gmc envoy. While making a left hand turn at 5 MPH, the vehicle made a whining noise and catapulted forward. The vehicle shifted gears and the speed decreased. The gears returned to normal and the contact was finally able to pull over. The vehicle was towed. The contact stated that the reverse gear failed and the first and second gears were barely functioning. The dealer stated that the sunshell in the transmission needed to be replaced in the transfer case. The previous damages LED to the entire transmission needing to be replaced. The contact was informed that the vehicle was not included in the federal safety agency campaign id numbers 03v075000, 01v283000, and 01v334000. The purchase date was unknown. The current and failure mileages were 63,000.
Normal driving conditions. Exiting from parking lot, heard loud bang, car jerked, came to a complete stop. Limped car home(1/2 mile). Upon further inspection 2002 gmc envoy had no reverse gear. Researching online shows 4l60e transmission, reaction sunshell & reaction sungears prematurely fail due to substandard parts.
2002 gmc envoy slt 60k...went outside to start car and had a loud swishing sound...tried to put in reverse...would not go...had to push out to get to work...extremely high rpms (3500-4500) to get through first...it also is jumping gears...if you try to go over 50 MPH the car will redline...was told reverse reaction shell/sun shell gear...they had a bunch of names for it...was defective and failed...we never towed w/ this vehicle, never got stuck (the gm service pro stated that this was possibly the reason for failure)...the vehicle is maybe driven 10k miles a year...we have had nothing but problems w/ this thing...we already have replaced the clutch fan last year...and had numerous little problems since...all the posts I have read clearly shows there needs to be a recall...the prices I have seen on posts is ridiculous to repair the transmission...$2k to $3k...so for now it is sitting in my driveway...I will get the quote this week from my mechanic and am not looking forward to it.
Transmission failure at 60,000 miles due to defective parts installed during the original manufacturing process.
Tl*the contact owns a 2002 gmc envoy. The air bag light is constantly illuminated and only dims when the vehicle is turned off. While driving 55 MPH, the contact attempted to use the 4 wheel drive, but it would not work. The indicator light remains illuminated; however, none of the 4 wheel drive levels work. The vehicle was taken to the dealer and they stated that the vehicle was not included in the federal safety agency campaign id numbers 01v283000 (power train:transfer case (4-wheel drive)) and 02v222000 (air bags). The current mileage was 127,000 and failure mileage was 95,000. Updated 01-14-08. *kb the consumer stated the 4-wheel light only illuminated when the vehicle was started. Updated 12/12/07.
Manufacture knew of inferior components within my vehicles transmission and did not issue a recall. Existing service bulletin #00-07-30-022c dated dec 10, 2004 (within my warranty period) indicates same issue I experienced in my vehicle on 10/23/2007. Bulletin title states replace reaction sun shell with more robust heat treated parts". This was known while my vehicle was still under warranty. Failure happened after standard warranty expired.
Transmission sun gear failure on my 2002 gmc envoy at 56,000 k. Gm is only picking up 50% of the $1747.00 bill.
My envoy was put into park when I went to lock the front door. When I got out of the car and took two steps, it slipped out of gear and went rolling down (very slight grade) the driveway in reverse. I jumped in to try and stop it before hitting neighbors cars. I grabbed the steering wheel to pull myself in, which made the envoy turn to miss on car, then it threw me out, almost running over both of my legs with the front wheel. It then proceeded to hit a satellite dish, and air conditioning unit (which all but ripped the door off the hinges.) it then finally stopped after running through a fence and it rested with one wheel in the air on a mound of dirt.
Dt*: the contact stated while traveling 25 MPH, the vehicle lunged, a whirring noise occurred, and the vehicle would not accelerate. It was driven home with high RPM's and low acceleration. At the contact's residence, it was noticed that reverse did not operate. The vehicle was driven to the dealership, but would not operate above first or second gear. The dealership determined the sun shell inside the transmission failed and the transmission needed to be rebuilt.
Dt*: the contact stated while driving various speeds, the 4-wheel drive indicator light illuminated, and the vehicle stopped as if the brake was applied when the accelerator pedal was released. Also, a smell was coming from the brakes and the vehicle accelerated without warning. The vehicle was driven to the dealer who determined the transfer case control module needed to be replaced.
I own a 2002 gmc envoy with 49,000 miles. The transmission failed, did not want to shift from first, then no reverse when I left the destination. Had towed to dealer. Service manager stated she had a hunch what it was but had to get it in the shop first. Sure enough, the sun shell failed and the transmission has to be replaced. Called gm customer service in an attempt to get them to fix it at there expense since this is an regular occurrence with there trucks. Have not heard back as of yet. Seen many many many posts around the internet about this very problem. This should be looked into.
Have a 2002 gmc envoy, bought new. 8 recalls, ball joint and speaker failures. At 32000. Miles, the transmission failed. Dealer diagnosed with sun-shell gear problem, that was addressed by a gm repair bulletin. At 37000. Transmission failed again. Dealer advised the entire transmission needed replacement, but it was not related to his oct. 05 repair. Contacted gm customer service, have a file number, but have not heard from anyone in 2 weeks. They advise that the gm area representative has not called anyone back, either the dealer or gm cs. ?? Asked to contact him myself and was told I could not do that. Asked where I could contact ceo rick wagoner and was told that no one can give out that info. A bunker in colarado maybe?
Dt*: the contact stated while driving 10 MPH, the sun shell gear fractured inside the transmission suddenly, causing the transmission to lose reverse, second and fourth gears. The vehicle was able to be driven to the dealership. Repairs have been made to the vehicle.
Went to back out of neighbor's driveway & there was no reverse gear; just like it was in neutral. After pushing the gmc envoy out of driveway, it would go forward, but was very "strained" to get into gear. I am the owner of his envoy since it was new; it has only highway miles; has always been serviced by the dealer from which it was purchased.
Continued electrical problems with 2002 gmc envoy. Such as on-star telephone along with radio/cd player, all four doors failing to lock or open including the back hatch. Service air bag light and engine check lights coming on. Reprogram engine/transmission module, also telephone antenna replaced, short in wiring located due to rubbing/pinching during construction, replaced wiring harness. Hundreds of dollars required to identify short in wiring. Transmission operates sluggish until warmed-up vehicle feels as if the brakes are on until it has moved several blocks.
We own a 2002 gmc envoy sle, which was purchased new december 2001 by us. In september 2004 at approximately 65,000 miles the transmission went out. My wife was driving the vehicle at the time. The envoy has a automatic transmission and 2nd gear and reverse went out. My wife was able to pull over and we took it to the gm dealership where we purchased it. They would only pay 50% for the repair to the transmission and we had to pay the other 50%. Less than 25,000 the transmission has went out again, having the exact same problem 2nd gear and reverse went out. Again, my wife was on her way to work and was able to control the vehicle and safely get it stopped. We took the vehicle back to the gm dealership and they are now willing to replace the transmission, however we have to pay 50% of that amount. My question is why was it not replaced the first time? I paid approximately $576.00 for the first repair and now they want me to pay another $1500.00, which is over $2,000.00. Why is another repair now not good enough to fix the problem? Why should we have to pay for a defective transmission? I have been doing some research on the internet and have found at least 119 complaints for the exact same problem as we are having, with gm settling with others on a 50/50 basis. I am just thankful that both times my wife was uninjured and I believe strongly that someone really needs to investigate this problem. Any assistance you might be willing to provide us would be most appreciated.
While driving my vehicle and the 4 wheel drive switch is in the off position, my vehicle will engage into 4 high and the 4 low light flashes like it's trying to go into 4 low. It will keep switching back & forth from 4hi to a4wd and then go off. This has happened a couple times now. Another time I was turning into a parking space and then my steering wheel became very hard to turn, my car was in 4hi with the 4 low light flashing but the switch was off.
I have a 2002 gmc envoy sle VIN # [xxx] purchased and serviced by malouf in north brunswick, nj. I have complained on two occasions that the 4 wheel drive light switch jumps from 2-high to 4-wd and continues to blink. While this is happening there is a faint scraping sound from under the vehicle and than the vehicle slows down to a gradual complete stop. It feels like the brakes are being applied. There also a faint odor of burning brakes. This 1st happened around august 1 2005 and than again in oct 2005 two times the 1st time the dealership re- programmed the computer and up dated it, its was ok for a little while. Than it happened again in oct. They told me there was nothing they could see and that everything was working the way it should be. There is something very wrong with this vehicle and im afraid this is going to happen at higher speeds. Please get back to me as soon as possible. *jb updated 07/18/2012 *js information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)
I own a 2002 gmc envoy with 70,000 miles on it. Went to drive to the store and the truck would not move. There is a wining/ spinning sound coming from the transmission. Reverse works, but all others do not. I have read quite a few forums on this topic and found this problem happens often. Please let me know want I could do about this.
Drove vehicle as normal without warning and after I stopped (shutdown the vehicle and restarted it) there was no reverse gear or forward gear. Vehicle was towed to the dealer where I was later told that the reverse gear had blown apart. Damaged parts were replaced and transmission was flushed and refilled. I'm concerned now because the vehicle is out of warranty and it is sluggish or slipping when it makes a 1st to 2nd shift. Will it require additional transmission work in the near future and huge $$ to repair?
I own a 2002 gmc envoy that I purchased new in february 2002. On 24 may 2005, the transmission failed with 68,920 miles on the odometer. There was no reverse or drive. The vehicle operated marginally in gears 3,2,and 1---enough to limp into the dealer. Luckily, it didn't fail on the highway...or I might not be here writing this complaint! After tearing down/checking out the transmission, the technician found a damaged sun reaction shell and sun gear. The parts were replaced, along with new gaskets and seals, the transmission cleaned and power flushed. The total cost of this effort was $2277. :-( :-( in doing a bit of research on this particular failure, I've discovered other gmc envoy, oldsmobile bravada, and trail blazer owners have been victims too. According to one of them, who works in the service department of a gm dealer, the repair instructions state the material used in the sun shell of the 02 blazer, envoy, and olds bravada wasn't able to withstand the heat in the transmission, causing it to strip (which is exactly what happened in my vehicle). He goes on to state. That in vehicles from 2003 on, gm used a "more heat resistant material" in the transmission that reduces the likelihood of the sun gear failure. I'm writing this complaint because I believe the root cause of my transmission failure...and those experienced by other owners... Was due to faulty material...which the manufacturer knew about...yet didn't inform the consumer about. I've never owned a vehicle, gm or otherwise, where the transmission failed at a young 68,000 miles! Help please!
