Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Envoy 4WD 6-cyl

Dear sir/madam, I have a 2003 GMC Envoy slt model 4.2L V6 4WD and as I was backing into my garage I heard a loud bang and whinning noise and I now have no reverse gear and when I select the drive gear on the automatic transmission I have a whinning noise, I have read the blogs on this issue and I believe that GM and GMC are very aware of this problem, this repair will cost me up to $2,800 plus tax to have the transmission removed and a re-manufactured on replaced on my vehicle. I was just glad that this matter happened at my residence and not on some back road in West va., I believe that as stated, GM and GMC is very aware of the problem with the 4L603 transmission that were used in these vehicles' and the problem with the sun-shell and the reaction sun gears that are like a grenade exploding inside the transmission. I would like for a recall to be started on this problem and the owners to be paid back on all of these repairs. The consumer stated the air ride suspension that was installed on the vehicle is dangerous. The air ride suspension deflated on both sides on the rear of the vehicle, which caused the vehicle to bottom out on stops. Updated 07/08/15

The gear shift selector cable became disengaged from the transmission while backing out of a parking spot. According to my mechanic, there is a small plastic bushing that became brittle and fell off causing the failure of the cable to maintain a connection with the transmission. This caused my transmission to become locked in the park position and unable to be moved into any other drive. While I was in a safe location, I'm concerned that other drivers in similar situations will become stranded in locations that are not safe. I conducted a recall search and found that this item has not been recalled. I placed a call to General Motors and lodged a complaint. According to GM, they have received a number of complaints about this issue but are not issuing a recall at this time. I asked GM to provide me the number of complaints they have received about this and they declined to give me that information. I am seeking to file this complaint, have it reviewed, and determine whether a recall should be issued for this vehicle.

2003 GMC Envoy sle with 42,000 miles. Check 4 wdrive light came on then went back off. Dealer stated that the tccm had to be reprogrammed due to a bulletin. It cost me out of pocket no warranties cover this. Also the fan clutches went out but was replaced by extended warranties. I'm also told by dealer that the steering links are worn & should be replaced. This too is at my cost. I have only had this car 1 year. These happened with just a few weeks of each other.

Envoy 4WD 6-cyl

  • Automatic transmission
  • 19,232 miles
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.
