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.

: 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.
: the contact stated while exiting the expressway at 45 mph the vehicle lost all transmission control. The engine revved and the vehicle coasted to a stop. The vehicle was put into park however, the vehicle still rolled. The vehicle was towed to a dealer for inspection. Upon inspection the transfer case and module needed to be replaced. There is a NHTSA recall #01v334000, regarding the transmission and transfer case. The vehicle has the same problem as indicated in the recall however; it is not included in the recall due to the VIN. No repairs have been made.
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 NHTSA campaign id numbers 01v283000 (power train:transfer case (4-wheel drive)) and 02v222000 (air bags).

I was making a slow left hand turn from a stop sign and my 2003 GMC Envoy drive train had locked up causing the vehicle to come to a dead stop in the middle of the road. When this occurred I noticed the lights flashing for the 4wd and 4lo switch even though the switch had not been touched. The vehicle corrected itself and 15 sec later as I was making a left turn into my driveway the vehicle drive train locked up once again. To remedy this I put the car in park and there was a loud clunk and the lights went out and operation went back to normal.
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 GMC Envoy 4wd, on 2 occasions the vehicle has locked the gear into 4wd and 4hi. Vehicle will not respond to command to shift gears to normal driving in 2wd. In turn this leads to problem with the vehicle braking system--vehicle takes too long to stop during normal braking. The vehicle also becomes very unstable on the road--keeps shifting sides making hard to keep the vehicle in a straight alignment during driving. I had the vehicle inspected by a GMC authorized dealer in November, 2005 at which point they found out that there was a problem with the transfer case which causes it to break apart. This in turn causes all the other systems in the vehicle to malfunction because it's a computerized system. The transfer case was replaced which temporarily fixed the problem until Feb, 2006 and the same problem recurred. I have made GMC aware of the problem and they referred me to the dealer. On speaking with the dealer I became aware that this is an ongoing problem with GMC Envoy and the dealer is aware of the problem. The only way GMC is resolving the problem is referring customers to the dealer for a replacement on the transfer case--which happens to be the same one that keeps malfunctioning. At this point GMC does not have a different transfer case that will resolve the issue once and for all. GMC is also willing to fix your vehicle as long as it's under warranty but once it's out of warranty and the problems with the transfer case persist, you have to pay out of pocket. GMC is aware of this problem with the transfer case but they are not letting the consumers know.
Electronic problem with 4wd was supposedly corrected in 2004, transfer case for 4wd was replaced in April 2005, and 4wd failed again during first day trying to use it during icy conditions after it was "repaired" in April. Had to drive on dangerous, slick roads without 4wd from fairbanks to palmer, ak. This is a major safety issue in alaska where winter driving can be very hazardous without 4wd. Have had it into dealer several times for loud squeak under vehicle when making turns or going over bumps at slow speeds. No corrective action by dealer. Could not get vehicle out of "park". Had to have it towed to dealership. They disconnected something and told me to be careful because whatever they did would allow the vehicle to be put into "drive" without having brakes engaged! had to drive it this way for several weeks until they got replacement part. Have had other problems with climate control, wind noise around windows, and more. None repaired satisfactorily.
I have a 2002 GMC Envoy sle VIN # 1gkdt13s322480641 purchased and serviced by 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.
My vehicle is a 2002 GMC Envoy. I have had 3 incidents with the 4 wheel drive system in this vehicle since December 2003. The newest feature with these vehicles, as with the cheverolet trailblazers is the automatic 4 wheel drive system. This system allows the driver to put this lever in and the vehicle will be in 2 wheel drive and will switch to 4 wheel drive when road conditions are a necessity for 4 wheel drive. My vehicle's 4 wheel drive system broke in December 2003. It was reported to me from alaska sales and service who repaired the vehicle that the front differential had to be replaced due to the 4 wheel drive system. Then there was a leak of some fluid under the vehicle noticed April through may 2004. The vehicle was in the shop at alaska sales/service again and a transfer case was replaced in the vehicle. Come winter in 2004, my 4 wheel drive needed to be used again due to weather in alaska. My vehicle was in for a major checkup on Dec 14th, 2004 and I was told the 4 wheel drive system was in good shape. I had the vehicle back in the shop within 2 weeks for a loud noise in the 4 wheel system. Again the vehicle was in the shop and another transfer case was replaced. My major complaint to the federal consumer complaint system is that this vehicle is a 2002, and this vehicle has been in the shop for the same problem more than 3 times under the 3 year new car warranty. I feel that the general motors corporation should buy this vehicle back or purchase a new vehicle for me due to the problems I have had to endure. I am in the process of finding a lawyer in alaska that will support the automobile lemon law.
Transfer case( 4-wheel drive) wasn't engaging. Vehicle was inspected by a dealership, who indicated that the transfer case shift control module was defective, and needed to be replaced. They also indicated that the part had to be ordered. A week later when the consumer contacted the dealership to inquire about when the part will arrive they were informed not until March due to the part being being re designed. The part # was 12590220.
The consumer experienced a problem with the four wheel drive. The owner says that the light for servicing comes on and the vehicle has been to the dealer for servicing on 9 occasions in the last 18 months. The dealership doesn't seem to know what the problem is all about. The diagnosis are as followed: on three occasions no problem was found, there were three transfer case repairs, there was a faulty ignition switch found related, wiring had to be replaced and a vdb was installed.
There is an issue with either the transfer case or transmission of my 2004 GMC Envoy xl. On several occasions, while performing slow maneuvers (20 mph or less) in and out of parking spaces or making slower right or left hand turns, the vehicle feels as if it is being held back by something, until a loud clunk is heard as if a gear disengages, and then the vehicle jumps forward. This has proven to be dangerous to me, as I have felt more than once like I hit something. The vehicle also experiences very hard downshift, into first gear as the vehicle comes to a stop. This issue first appeared on the vehicle in December 2004, and has continued intermittently through the current date date (for more than 5 separate instances).

Computer that activates the four wheel drive is inoperable. It goes into sleep mode and consumer doesn't know that he is in 4-wheel drive. Consumer contacted the dealer, who updated the computer. It seems to be fine.
Failure of engine cooling system and four wheel drive system.
While driving at a low speed and turning to the left, the four wheel drive engaged. The dealership replaced the selector switch twice for the four wheel drive.
Our 02 GMC Envoy randomly shifts the transfer case into neutral while driving causing a no power situation in traffic. This has put my wife and child in danger on more than one occassion.
4-wheel drive light, my 2003 $35,000 Envoy's service 4-wheel drive light came on the first time at 574 miles. The second time at 4,242 miles. The third time at 6,490 miles. The fourth time at 9,387 miles. It was then towed in for a fifth time just after that for several other problems. It went through three ignition switches in one week. It has had the transfer case modules, actuators, front hubs and more done. It has been reprogramed each time as well. I have only owned the vehicle for 9 months. I contacted gm about this and was told about a repurchase then told no. I hate my Envoy and I will never purchase another gm product!!!!!!! everyone that asks me about it I tell them my story so I hope it gets around how bad this is and how bad this sucks! my dealership has been helpful but the reps from gm suck! I was never given a reason as to why the gm rep (moiz ahmad) said "no" and I was told that he not only doesn't have to give a reason that he doesn't have to call me when I asked for him to. And. . . They will not give me any information to even contact this guy. "they don't have to". Then when I complained that this was "unexceptable" and asked to speak with a supervisor the supervisor hung up on me!!! I was not very suprised to see that I am not the only one with this problem. I looked up the service bulletins and recalls (at alldata. Com) and there were several bulletins on this. Gm needs to get the Envoys act together!!!! I am going through NY state lemon law now. Wish me luck!.
Service 4wd light came one with 2500 miles on new 2004 GMC Envoy. Replaced actuator, then a control module on transfer case. Was told neither fixed the problem. Now told the transfer case must be replaced.
Transfer case: while driving at highway speed of about 65 mph with the transfer case swtich set to a4wd the trransfer switch without any input or operator control switched to 4hi (both the switch position and indicator light) and the 4lo indicator light was flashing amber indicating the transfer case was attempting to swtich into 4lo. This has occurred aproximately 6 times previously at various speeds, while driving striaght or conducting turning maneuvers; but only when the engine is warm. The latest incident on 12/28/2003 (prompting this complaint) occurred after the dealership completed the remedy specified by service bulletin 02-04-21-002a on 12/26/2003.
While driving the 4 wheel drive automatically engaged. The consumer tried to manually disengage it several times. The dealership was notified, but has been unable to resolve the problem. Please provide any additional information.
When vehicle started up, 4-wheel drive light came on. Diagnosed as no codes stored in atcm. Old atcm programming scanned for codes no codes stored. Reflashed atcm with new update.
When the light went out on the 4-wheel drive, the consumer had to the shut vehicle off and restart the 4-wheel drive. During snow conditions, the owner found out the vehicle would not shift to 4 wheel drive when the indicator light was on. In order to restore 4 wheel drive the vehicle must be shut down and started again until it lights up . The vehicle has been worked on three times with no repair orders provided.
While driving down freeway my check 4wd light came on. So now it is in the dealership for 2 days, with only 1600 miles on the vehicle. . . No 4 wheel drive ever used yet. . . It not going the way I expected for the price of this vehicle.
While traveling 35 mph on the highway and without prior warning 4-wheel drive will automatically go into effect.

My husband and I purchased a 2030 Envoy slt in may 2003. The 4 wheel service light has come on twice. The first time, it was repaired. The 2nd time it came on, we were told we have no 4 wheel drive. We have been in contact with GMC customer service dept (1-866-996-9463, our representative is brandy johnson and our ref $ is 1-127444813). The resolution; we need to wait until the service 4 wheel drive light comes on again so we can take it into the dealer (if they are open) so a "code" can be read. I feel with winter coming, this issue has now turned into a safety issue as we will use this vehicle daily to take our son to daycare and go to work. I would appreciate any input you could assist me with as I strongly feel this vehicle should be replaced.
With about 1100 miles on my brand new car , the 4wd light came on. Not happy about this purchase.
When my vehicle had less than 200 miles on it the check four wheel drive light came on. Whe had only had the car for less than a week. I asked the dealer and they said that as long as it was running fine the would put it on the computer at my 3,000 mile checkup. A few weeks later I started hearing a rubbing noise. I brought it in and they took it for a test drive. They told me that they had swiched it from 2 wd to 4wd high and the noise was gone. It was not. The next day I switched it into awd and there was no noise. That afternoon the front wheels locked up on me when I was going about 30 mph. We had the vehicle towed back to the dealership. They told us that the front differental was litteraly falling apart and have now said they are going to replace the transfer case. The milage on our Envoy is 1263. Needless to say, I am not happy. I purchased a new vehicle so I would not have problems. I have only had it for a month.
GMC Envoy 2002 sle xl purchased in the month of June and started having problems in oct. The vehicle would shift in and out of 2wd and 4wd on it's own and on occasion it would lock the wheels also. Problem mostly occured when making turns. Stated problem to dealer (10/18/02) - dealer replaced 4wd selector switch (reason: internally shorted). Had problem again in month of Feb. '03. Brought vehicle back to the same dealer and explained problem again (02/21/03). Dealer replaced 4wd selector switch again. Reason why I'm filing this complaint is because I feel this vehicle is not safe. I also realized that I'm not the only one experiencing these same problems. My hope is that GMC will take notice and correct this problem quickly.
While towing vehicle in neutral, transmission slipped out of gear and a fire started in transmission area. Contacted dealer who was not willing to do anything. Consumer states that the transfer case shift module failed to engage neutral, consumer had brackets and wiring installed to activate the brake and tail lights when being towed, there is a recall, 01v334, regarding transfer case control module problems, however this VIN is not included.
