We have a 2003 Envoy that I had some concerns about early on due to things I had heard about computer related problems. I talked with the service manager at our local GMC dealership about these concerns before we bought our car. He explained that many dealer service departments have poorly trained personnel who don't know how to handle these (usually minor) problems when they occur. He further stated that our local dealership had specially trained people who knew what they were doing. This has proven to be true in our case. We have not had a single problem with our Envoy, and after nearly 60,000 miles it still performs flawlessly and gets an incredible 24 mpg on trips. We love everything about this car and will most certainly replace it with another one when it hits 200,000 miles or so.

I have a 2003 Envoy XL just hit 30K. Now I have a service engine soon light illuminated. Autozone diagnosed as Emission Control System leak. Anyone ran into this one? The thing seems to be running fine. Just wondering if it is one of those factory preset lights to get cash out of my pocket.

I had this problem with the check engine light too. It was a clogged vent hole in the gas cap. It really won't hurt anything (except making that stupid, too-sensitive light come on) but it's an easy and cheap fix. You can just replace the fuel cap.

I have a 2003 envoy and just hit 112000 kms. My engine light came on and I got it ran through a test, it turns out I need a new clutch for my fan... yikes it is expensive!!!

The service engine soon light is related to a problem in the design of the fuel tank. There is a weld that fails where the filling nozzle is attached to the gas tank. It does leak fumes and gas. There is a TSB on the 2002 models. NHTSA Office of Defect Investigations has launched an investigation into this problem which occurs in the 2002 and 2003 Trailblazer EXT and the GMC Envoy XL. If the Service Engine Soon light is on please have it checked out immediately.

I just picked up my 03 Envoy XL from the dealership Friday with the following repairs being done: The blower motor was staying on after the vehicle was shut off and draining my battery. The problem was a bad module. And the check engine light was staying on and a fuel smell coming from the back of the vehicle. The problem was a crack in the fuel tank.

The repair bill cost me $1291.00 due to being out of warranty. The vehicle has been good, my suggestion is to purchase the extended warranty. If I would have it would have paid for itself...

Would like to see feedback on how to get this fuel tank problem out in the open, it seems like its time to declare a recall...

Our GMC 03 Envoy XL just shut down on us.

We took it out for Lunch, when we came back, the car would not start. The wierd thing is all the panel instruments went haywire, the rpm indicator went to max and remained stuck there, the speed gauge went to 20 miles..etc, even after I took the key out off the ignition.

When I put the key back in to try again, the key got stuck inside and would not come out, all the panel gauges were still stuck at different levels of activity. All you could hear was a constant clicking sound.

We finally had to get the tow truck to tow it to the dealership.. its been a full day and they have no idea what the problem is. Has anyone else had such an issue before?

We have a 2003 Envoy XL with 55k miles on it. It runs great. The only problem we've had is the gas cap. The "check engine" light comes on because the gas cap is not making a tight seal. We're on our 3rd gas cap in less than 3 years. Poor design, and potentially a safety hazard as well.

Anyone knows where I can buy a metal gas cap that fits???

I had the same issue with the gauges going haywire on my Envoy. I brought it in and they said that the computer was stuck at 60MPH. I believe that they had to reset the computer.

I have 2003 Envoy and since I bough it I have nothing, but problems the first thing was the crack on the fuel tank, well now there is a recall for it after 4 years, second the clutch for the fan went out, bought it, replaced it; it was not an easy job. Third the resistance and the blower motor for the A/C are faulty for the speed 5, the blower motor only work from 1-4 speed. Fourth Now my vehicles is overheating it might be the thermostat because it came out with a code saying the temp in the engine and the radiator was not the same. My vehicle only have like 55000 miles. I wonder how many more things are going to break in this vehicle.

Yesterday, after filling my gas tank (full) on my 2003 Envoy, my service engine light came on. After reading on the Internet about the possible problems and remembering that I received a letter from GM about a recall on the gas tank, I called the dealership. They checked it immediately and found that it was indeed a crack in the tank. They could not fix it before I am suppose to leave on vacation Thursday, so they are renting me an Envoy to drive. They said the tanks are on back order and did not want me making the trip with the defective tank. (They said GM is paying the rental) My Envoy has 65,000 miles and no warranty. (I will update my comment with the "rest of the story" later.

Just two weeks ago, after stopping at the grocery, my Envoy decided not to crank. It Appeared at first to be the battery, but then it was suggested it may be the alternator. Long story short, it was the battery. But during this time that I was trying to get it to crank, I experienced some of the problems previously mentioned by others about the gauges going haywire and the key getting "stuck". That was a weird experience!! Anyway the new battery solved everything.

Occasionally, when I first take off I get the feeling that the transmission is having problems changing gears. This will last for a minute or so, then go away. The problem is not consistent at all and I can never "reproduce it" for a mechanic. Overall, the Envoy has been a very good experience and extremely comfortable to drive.

Take it in quick or sell it. Mine acted the same way about the time you posted this today. I just got home from work and don't have reverse at all. Reading up on it, it seems to be a problem with our trannys. I too have a 2003 Envoy (4x4).

I am a previous owner of a 1997 Jimmy, and now have a 2002 Envoy. I loved my old one so much that I updated to the 2002.

The only big problems I have had was the key wouldn't come out of the ignition. Seemed to be a problem with the tumbler in the steering column; cost about 90.00 to fix.

Other than a recall on the wiper motor, I have had no problems.

I have taken my 02 Envoy on vacation; a 2070 mile trip with no problems. It now has 103000 miles, and I drive it everyday, and I love it as much as the day I bought it new.

Call me lucky for no troubles with mine, and I will continue to own one because of my good luck. It's the perfect size for my family of 3.
