See all problems of the 2003 GMC Envoy 🔎.

At lees than 1/4 tank of fuel the gas gauge is close, after refueling, the fuel gauge goes way past full and will stay like that until fuel is below 1/4 tank. Last time the truck took 19. 85 gallons in a 20 gallon tank until it started working correctly again. One tank it worked fine and next fill up it was way beyond full again. At the same time when fuel gauge is wrong, the speedometer will be off. Many times freezing at 35mph while traveling 65mph. After many resets of ignition, the speedometer will come back. Also when all of this is happening with the speedometer and fuel gauge, the radio has no audio. Every now and again, the radio will come back and work on one speaker. Most of the time it is out. When weather is warmer, all 3 functions seem to work regularly. Below 50 degrees, all malfunction.

I went to get my vehicle smoged and the smog tech let me know I have a leak from a clamp. When I got home I went to replace the clamp and saw that the neck on the gas tank was completely broken and that was where the actually leak was coming from. Apparently this is a big problem with other peoples GMC Envoy's, it is very dangerous, and the neck is made out of plastic. Now I am at a loss of a car until I can afford to fix it. This defect should be replaced by the manufacturer not by the owners.

2005 GMC Envoy out of the blue my speedometer works intermittently and my gas gauge reads empty with light on even though I have a full tank of gas! additionally the factory speakers work intermittently. This vehicle has electrical issues!.

The fuel tank neck where the fuel goes into the vehicle, then down to the gas tank, has in the plastic & leaks fuel & gas vapors so the check engine light is always on. My mechanic said there is no way to fix this without purchasing a new fuel tank since this is all one piece.

2003 GMC Envoy. Consumer writes in regards to a defective fuel tank. According to the repair invoice, the fuel tank neck was cracked and leaking.

I received a letter from GMC approximately a year ago stating that there was a recall to the fuel gauge on my vehicle. I didn't think anything of it since I had not experienced the issue and the letter stated not to take it to the dealer unless you currently had the problem. As of a week ago the fuel gauge stopped working. I fueled up until the tank was full and the gauge reads as if the tank is empty and the low fuel light is on. In addition the speedometer has is having issues now as well. It sticks at highway speed and then just goes to zero and stays there. If it weren't for my gps I would have no clue what rate of speed I am traveling. I have contacted GMC customer service as well as the dealership and the repair for the fuel gauge will cost me $240 with GMC paying the other half. It seems to me that they were aware that there was an issue before I did so why am I now stuck with the repair bills? why was this not fixed before the vehicle was sold to me since I purchased it used from the dealership? something should be done about this. I should not be held accountable for GMC's errors! in addition there are recalls on the other GMC models for the cluster gauge that affects the speedometer. The Envoy was not included because there were not a sufficient number of complaints. Once again why should I be stuck holding the bag on faulty equipment? what can be done to get this resolved?.

(2003 GMC Envoy xl) I have recently found that my wife and kids have been riding around in a vehicle that was an explosion waiting to happen. General motors has extended their warranty on fuel tank issues 3 times because of a flawed design. I had no knowledge of this before purchasing, as I believe I am the second owner of this vehicle. I have since seen that this issue has been brought to your attention but not to the magnitude to which it is occurring. I wonder if someone has to die a fiery death before this issue is addressed seriously ? I have compiled many accounts of customers complaining of this issue and have records to share. I have contacted gm customer support, only to be put on hold for a total of 153 minutes in the realm of 4 calls with no resolution. This engineering failure consist of great numbers still on the road. Unlucky ones like myself will not have any knowledge of this until total failure occurs and at that time gm's poor design becomes the burden of the current owner. I need help understanding how such a safety risk can be swept under the rug with 493,579 of these vehicles being sold. I have found that the design was so bad that aftermarket suppliers do not even offer this tank. The only place to get one is from gm dealer at a price of $650. 00, which is exorbitant for a piece of plastic. I need help with this matter but it's not just about me, your actions could save someone's lives !.

The approximate failure mileage was 70,000.

Nearly 2 months ago I noticed the gas gauge in my vehicle going haywire. I will fill the tank, and within a mile or 2, the gauge will drop to e, and the light will come on, bell will sound, etc. It may or may not adjust while driving. This happens constantly, the gauge is showing 1/2 full, then empty, then 1/4 full. At any given time, I have no way of knowing how much fuel is in my tank. I am deathly afraid that I will run out while driving with my children on the interstate. I have researched the problem a little on the internet, and found many, many others with this problem. I firmly believe this should be a recall issue.

After filling the tank in my 05 Envoy the gauge reads empty for a while, then goes up and down.

Fuel gauge does not work. I will fill up the tank and turn on the car and it reads low fuel and the indicator light comes on. Then I can be driving and it will jump up to past 1/4 tank then slowly go down to e and read low fuel.

The fuel sensor on my vehicle swings wildly from empty to full even when the fuel tank has just been filled. This results in the check engine light to constantly be on. I am unable to determine how much gas is in the car due to the faulty sensor. I have checked the internet and this appears to be a widespread problem that has been reported for years. I called gm and they told me that they have known about the problem and will cover 50% of the cost only if I take it to a gm dealer and that my portion of the cost would be between $500 - $600 dollars. They would not cover any of the cost if I take it to my local mechanic. This problem has been known by gm for years and they should have issued a complete recall to repair the defective part(s).

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.

The fuel indicator gauges from full to empty within seconds even though the tank has been filled completely. The gage remains on empty with the 'low fuel' indicator warning light on for the length of the trip.

The gas gauge on my 2005 GMC Envoy slt has began reading incorrectly. The gauge reads empty even when the tank has fuel in it. After a day or so the tank reads normal, then it begins to fluxuate from correct to empty. Then the check engine light will begin coming on, and will go off again with no resetting.

Fuel gauge shows empty when tank is full. It will work again at about half a tank, then when we refuel it will go to empty again. Then it will start to go up to about 1/8 tank, then go back to empty. Sounds like this is a major issue with gm vehicles.

Fuel gauge drops to empty even if tank is full. Will also fluctuate at any time so accurate level is unknown. Danger of running out of gas with no warning while driving!!!!.

I have had a problem in the past with the fuel gauge reading empty continuously as I have read from many other complaints. Recently I experienced a problem with the oil pressure gauge. At first the check engine light appeared intermittently and then the oil pressure gauge dropped to zero, at which time the message in on the lcd reading said "stop engine" and "oil pressure low". I immediately went to my gas station and checked the oil, which was only down a 1/4 tank. My mechanic stopped the car and started it again and the oil pressure gauge reset itself but once I started to drive the car again, the oil pressure dropped. My mechanic believes it is another sensor problem like the fuel sensor but is not completely sure. I only started with this issue today but it is more worrisome to me than keeping track of how much gas should be in my tank. I am curious to know if others have started to experience this problem. I have had the car since it was brand new and have drive 79000 miles. I also had a major issue with the suspension system with I believe is common in this vehicle.

I recently smelled gas fumes in and around the vehicle and I do an a visually inspection of the fuel system of my vehicle. I found a leak of fuel coming from the fuel tank;just from the fuel tank neck. I am really worry about it because most part of the time I am traveling with my son. Recently I do a research and found NHTSA action number pe07014 about a recall from GMC about the 2002-2004 GMC Envoy and chevy trailblazer about the same problem just happen to me.

I have 2003 GMC Envoy, smell gas fumes when gas tank is half full, no gas is leaking on the ground. Will chevy cover some of these repairs? seems like a number of owners have this same problem,.

After filling fuel tank, sensor went to empty imediately. Chimes activate and fuel gauage reads empty.

The gas gauge on my 2005 GMC Envoy has begun reading incorrectly. The gauge reads empty when I fill it with fuel. After a couple of days the tank appears to return to what I believe is a normal reading. Then, on it's own, it will fluxuate dropping to empty, triggering the low fuel light and alarm and then return to it's previous position. At this time, I cannot trust the gauge to be accurate.

The contact owns a 2004 GMC Envoy. The contact stated that there was an overpowering gasoline odor inside the vehicle. The vehicle was taken to a local mechanic who advised that the fuel tank exhibited a leak and needed to be replaced. The contact called the manufacturer regarding the fuel leak and the manufacturer suggested taking the vehicle to the dealer for repairs. The failure mileage was 60,000.

I was driving down the road and fist off, my speedometer went crazy. Then my fuel gauge went all the way to full, then to empty. Then it wouldn't work at all. There was plenty of gas in the tank too, I took to a mechanic and he replaced thermostat, but it didn't fix the problem. I'm still having the problem and heard there is a recall on the 2005-2007, and it appears I'm having the same problem on this 2003 that they are having now with the newer ones and the 2003 should be included in a recall. Please evaluate. I only have 107k miles on the truck. I was told, a recall could cover up to 120k miles, so I still have some way to go before I should not be included in the recall. My service engine light is staying on too, although it's been checked numerous times and it's always something to do with the fuel system and too expensive to get fixed. Now I am having major problems because of it.

Gas hand reads empty and does not move from empty when tank is full of gas.

I noticed that when I filled up the tank the light came on as if the tank was empty. I actually stopped when I was pulling out of the gas station and looked at my receipt and questioned the attendant. The tank was full. The gauge was erratic from then on going from full to empty in a matter of two to three miles and it has been happening regularly. The funny thing was that I just got a letter from GMC advising me of this problem and magnanimously offering to pay for 50% of the cost. I couldn't believe the timing. Thinking it was a minor thing I called the local dealer to set up an appointment and found out that I am facing a minimum of $600. 00 for dropping my gas tank and checking to see what the problem is. Seriously!!!???? when I researched this it appears that this is a rampant problem with these vehicles. Why is this not a recall?? why am I burdened with this ridiculous cost when it is apparent that this is a manufacturing problem. This is a very dangerous situation as a false reading on the gas gauge could make the driver think they have a full tank when in fact it is empty an the vehicle could stall out in the middle of traffic and cause a horrific accident. I would like to add my request for action from GMC to fix this problem immediately at their expense - not the consumers'.

Fuel gauge stays on empty after filling the gas tank. It may alternate from full to empty intermittently.
