I just experienced a safety defect that could have had very serious consequences. It involves the failure of the shift cable attachment to the transmission mounted shift lever. You unknowingly loose the ability to place the transmission into the "park" position, with the resulting vehicle movement of an apparently parked vehicle. Please contact me ASAP. -- thanks.

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.

2006 Envoy only has 50,000 miles and the flywheel is going bad which may lead to future problems with the transmission there is also a fuel gauge problem where I fill up the car completely and it still reads empty. To replace this would be $800 dollars!!! I have found other websites where other people who own this car are having the same problems. There needs to be a recall!!!!!!! this is ridiculous. Thank you for listening.

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. .

2006 Envoy denali. Consumer writes states gas needle stopped functioning the consumer stated the gas needle began to fluctuate in the beginning and since that time, the needle has been stuck on empty, and the engine light illuminated as a result. In March of 2009, when the consumer stared the vehicle, it sounded as if there was something metal tumbling around under the hood. Upon inspection of the vehicle, it was determined the engine needed to be replaced. On June 10, 2010, the vehicle would not start and had to be towed to the dealer. An inspection revealed a starter was needed. Also, an alignment was done and the rear brake light was replaced. On June 12, 2010, the vehicle would not come out of park. After 25 minutes and over 50 attempts, it finally came out of park. The consumer drove to the dealer, but they were unable to find a problem. September 2010, the consumer noticed the rear of the truck was sitting very low. The rear end air suspension needed to be replaced. The air condition randomly worked. There were times where the air would just start blowing and no buttons were pushed. Also, the defroster stopped working. The consumer continued to experience problems with the vehicle not coming out of park.

The transmission would "clunk" upon starting and stopping. One day while driving there was a bang and then the gears would not shift from 1st to 2nd without revving the engine very high and then letting off the gas. The next morning there was no reverse. The dealer said it was the reverse sunshell gear that broke. It was replaced.

Truck service engine light has continuously come on and off. The transmission went and lost all gears at 52,000 miles, after the vehicle had been in at 31,000 miles for the same reason. There have been multiple items in which the service engine light has been transmission several times but dealership could not find anything, fuel cap, fuel tank neck, internal gauge for the fuel tank, and only to get the vehicle back on 3/19/08 and for the service engine light to come on again. I swear this truck is a total lemon! I have had nothing but problems with this vehicle, and every time I have taken it to the dealership they can never find anything wrong. This last time was a total fight with the dealership regarding the transmission, along with no morals and respect for the consumer from gm themselves or the dealership. I believe that I have ended up with a lemon, and there is not a darn thing I have been able to do about it because no one seems to think that there is a problem. Contacted on-star to run diagnostic checks every time the service engine light has come on and they can not seem to find anything so I end up taking it to the dealer for 65. 00 an hour for diagnostic check and being told there is something else wrong with the truck and was assured that they ran all diagnostic checks and cleared all the codes after fixing the transmission. This is beginning to become very annoying, costly, and unreliable when transporting children in what I call an unsafe vehicle. I have put more money into this vehicle than what it is worth with such low miles!.

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.

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.

Bought "certified used" Envoy in October of 07. Transmission completely stopped at 57k miles 3 months after purchase. Check engine light comes on and off every couple days(have video, but sandy sansing of pensacola florida says there nothing wrong) vehicle jerks at stops and starts. After 3 trips to dealership w/ "nothing wrong" they finally decided that a O2 sensor was bad at 71k. Envoy had been back in the shop at a cost of 80. 00 bucks twice since then because of the "check engine" light and the brakes are failing, the "abs brake" light doesn't come on so they say it cant be the brakes. When trying to stop the brakes stop working and a second later they will catch and begin to stop vehicle, as if the brake system is obstructed and skips a few times. The check engine light flashes for those few seconds but doesn't stay on long and they say it isn't throwing any codes. Problem doesn't happen everyday so the dealership has said its a unfounded problem. The thermostats assembly with other parts have been replaced. Have all receipts and dates that I've taken this pos into the dealership. I will never buy another GMC vehicle. I have a 10 year old pickup truck also and has only been in the shop once. There's no excuse that we are driving these (expensive) unsafe vehicles!!.

Transmission line mounted too close to catalytic converter resulting in rubbing action that resulted in a hole in the transmission line spraying fluid on hot exhaust parts. Had to pay to have hose replaced. Don't know if the eventual failure of the transmission at 73k miles was related, but had to pay $2700 to get a new one installed.

I was driving in town and my speedometer stopped working at 0. The oil gauge is not working, pegged out at the max and my engine light is now constantly on. These events, particularly the speedometer not working, is a major safety hazard. Not driving at controllable speeds can lead to an accident and death. The parts and labor to fix this problem is $550. While researching this problem on the internet, I've found out that this is a common problem with GMC's in this year. There should be a recall with the cluster unit on 2004 GMC Envoys. GMC should try to prevent deaths that their products may create.

Sun shell replacement on 2002 Envoy xl. We had the same problem with this defective component. I worked for gm and had no problems having this defective component replaced at 100% dealer charge. We paid $0. 000 (nothing) gm knew they had problems and didn't' correct the problem. Ours failed 20 minutes after having a transmission flush/service with only 35k miles on our 2002 vehicle. I would fight with the dealer. There are service bulletins out there regarding the failure and replacement of this component. Ours failed when my spouse tried to engage the gear into reverse. Good thing this didn't' happen in an emergency situation where she needed to get out of a bad situation quickly. The local dealer paid for our this should be the same for all dealers across the nation as long as it's an apple to apple comparison. Owners in one state should be afforded the same replacement policy and pricing as owners in other states. The manufacturer and dealers should treat everyone fairly.

2006 GMC Envoy denali purchased 12/05. Beginning at about 10,000 miles the transmission would shift abruptly into 1st gear after the car had stopped moving. This does not happen every time but when it does it feels as if the car has been hit from behind. Dealer has not been able to duplicate the problem but states that other owners have reported the same problem.

I have had my GMC Envoy into the dealership on multiple occasions for a noise coming from the rear. I've been told that it is just a flaw in the design but it is a very annoying flaw. The noise is a constant squeal that only goes away if I take the vehicle out of overdrive. The dealership said from me not to drive the vehicle in overdrive because there wasn't anything they could do to fix it. As time goes on, the noise seems to be getting louder.

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.

: 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.
