2004 GMC Envoy Xuv: check engine light

Filed Aug 17, 2015 · Engine · 111,848 miles · CA

2004 envoy xuv, impeccably maintained, car was parked in my drive way and I started it to go to the store and it started chugging and then almost died, but then went back to normal but the service engine soon and reduced engine power lights illuminated on dash.turned off engine. Restarted, and the service engine soon light was still there so my husband hooked up his code reader and it had the code p1680 ( throttle body postioning censor.) and this isn't the first time it's done it but the engine light has always just flashed it would never stay on so we could read the code. But in order to fix this you have to buy a whole new throttle body housing because the censor is built into it. And it isn't cheap. At autozone it is $280.00. And you have to also buy a gasket for it and new intake manifold gaskets because to remove the throttle body housing which is connected to the manifold you have yo remove the manifold also. How in the world does gm expect us to be able to fix this issue if it's always so much money for parts for these cars. And I also have issues with my back tailgate and both big window motors. I have replaced one but still saving up to replace the middle one and I've also had issues with my gas tank which is $677.00 or more at the dealers for a new gas tank because u can't just fix the filler hose. Such failures will eventually kill someone. So I think gmc needs to take a longer look at these gmc envoy xuvs and get some recalls out to fix these dangerous problems. And honor all cars that come in no matter what. Because we had to fix the gas tank issue ourselves because we could not afford to buy a new gas tank.

Bought new and loved the ride.list price was over $42,000. Well maintained. 1st lost speedometer and other gauges. Replaced instrument cluster. 40k miles replaced blower motor. 60k miles window behind backseat just dropped. Replaced regulator (I think). 62k miles check engine light - replaced fuel cap then took to dealer - $600 replaced a oxygen sensors. Check engine light came back on a few days later with same code. Just driving with it now. 68k miles - replaced power steering pump.89k miles - driver side power window module burnt - replaced. 91k miles - while replacing driver side headlight found wire to light was melted. 98k miles rear speakers quite working. Probably a couple of things I have forgotten. 8-12-14 it has 99360 miles on it and still love the ride but have lost faith in gm. I have had 7 gm vehicles and will have no more after this one.some of these items have had a recall but not for this vehicle even though the same parts are in this one as the recalled vehicles.

Misfire was detected dealer code #p038. Dealer claim was a spark plug problem. Spark plugs and cables were replace. When I went to pick up the vehicle, the check engine light was on. Dealer technician claimed there is a prolblem with the tank that is leaking and needed to be replace. They stated the problem is on most of this new tanks. Just wonder if this a manufacturing problem since it can cause fire or explosion at any time on the road.

A year after the purchase of my new 2004 gmc envoy xuv my service engine light came on and an authorized service tech said I needed a new gas cap because of a small vapor leak. I bought the new cap and a few months later the engine light came on and again I bought another cap. From then I had been told by different mechanics that the vapor leak is coming from the nozzle the cap attaches to but today for the first time I was told I would fail my smog check because the vapor leak according to their diagnostics was not coming from the nozzle, but somewhere else near the tank. After research on recalls and complaints, I found out that my problem was similar to other complaints, that being the gm service bulletin 05-06-04-014a: info - diagnostic aids for trouble codes p0440, p0455 & / or p0442 fuel was leaking from the crack, and that the 2002 - 2004 envoy may have issues with a crack in the gas tank filler neck as well. I checked out the assembly system and yep my filler tank connection from hose to tank is loose and showing evidence of gas leaking down the tank. It wasn't a small vapor leak, it is a mushroom cloud event just waiting to happen to my backside! The interesting part of this disaster is that they did this as far back as I could search, so far as early as 2001. Gm had advised their mechanics that the problem was resolved and redesign of the system was in place with welded units attaching the components, rather than rubber booting to plastic tanks. I have the internal memo of their declarations for three years so far. Today, I'm in possession of a loaded bomb and see that tsb's are issued for years through 2009. Plus theres a discrepancy with service warranties of 10 years or 120,000 miles vs 150,000, I have those internal documents from gm to the dealers as well. I cant afford this. Other envoy owners I've talked to are saying the same things exactly.

I had a 2004 gmc envoy xuv and had several things going wrong. The speedometer was radical, some days it would work and other days not. The back window of the vehicle would be down for no reason at all when I was not even in or near the car. The engine light would come on and go off. Like a fool I just purchased a used 2004 gmc envoy xuv, only owned it 2 days and smelled gas. Looked under the vehicle and the entire rear of the underside of it was covered in gasoline. There was a small puddle on the garage floor. Took the vehicle back to the dealer and they took out the gas tank and there is a leak in the filler neck. Still waiting to get the car back, can't find parts. This will be my last envoy.

Took vehicle in for inspection and check engine soon light was on. A code p0455 was found which means a large gas leak. It was discovered that the gas leak from the gas tank seal where the filler neck hose attaches. Repair is replace fuel tank as the filler neck is built into the gas tank.

Smell of gas inside of vehicle, check engine light on and notice of gas on garage floor. Took vehicle to a mechanic and found out that the gas tank was leaking around the neck of the tank where the refill hose connects. Found out that chevrolet and gmc had a special coverage adjustment # 07099a on this problem. I took my vehicle to the dealer and I was told that my vehicle is not covered on this sca because of the VIN number. I called gmc customer service on recalls and I was told the same thing. The dealer agreed to pay 2/3's of the bill and I will have to pay 1/3 of it. On the sca sheet it list the following for my vehicle. The last 8 digits of the VIN starting with 46100001 to 46116824. My vehicle is leaking so badly that I can smell gas inside of the vehicle all the time. It is very dangerous to drive. Also I park my vehicle in my garage all the time and this is dangerous. I think that all of the 2002 to 2004 chevrolet trail blazers and gmc envoys will have this problem with the leaking gas tanks. The problem is with the design of the tank. I was told by the service tech at the dealer that they use to have a lot of problems with the gas tanks. He said that since they have changed the tanks out on the covered vehicles that they have had none of the vehicles back in with leaking gas tanks. This is a big safety issue that needs to be corrected. Some people would not notice this problem and if they have an accident this could cause more injuries and possible deaths. This could also cause an explosion around sparks or static in someone's garage.
