Repeat problems since car was purchased brand new at dealers. Air /O2 sensors defective/replaced. Defective fuel pump/fuel sensor/electronic gas gauge; flickering/dimming headlights; freezing/inability to control driver's side seat and controls. 1/4 of front instrument panel lights out; drivers side seat control lighting 1/4 out; check engine light and low fuel light on continuously since 1997. Tie rods both replaced as well as both front sway bars. Immediately following vehicle purchase, check engine light would continuously go off. I would call onstar at which point I was told to take car in for repair w/I 7-10 days (often told a problem w/powertrain or transmission). At dealers service dept, told over and over again after tons of worry, concern and time spent, that electrical system on this car tends to trip/trigger check engine light and they would just reset it so after awhile, I began to disregard the light as I was in the dealership almost weekly. Approx 2 yrs after purchase, filled up gas tank and fuel light showed "low fuel". went back up to full, dropped to 1/2 and back to empty. Went back to full after car was turned off and continued to do this. After about 2 weeks, constantly stays at empty. Called repair shop and was told approx $700-800 to drop tank and replace fuel sensor which I could not afford and began to track odometer and refill tank after 200 miles driven after fill up. Have been doing this for 5 years. Jan 29,2011, I go for emission test. Fail D/T low fuel and check engine light being on. Go to mechanic, approx $950 repair. Check engine light goes off...and back on next day. Read thousands of posts online and am finding many, many Envoy owners experiencing same problems as mine. These are safety issues and GM should issue a recall on entire fuel and electrical system. Please call for questions/clarification.

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.

Gasoline and oil pressure gauges stop working suddenly on a GMC Envoy 2005.

Same problem everybody else is having with there Envoy, floating fuel needle, now my check engine light is on which occasionally will go off, but now I can't pass emission inspection because my check engine happens to be on, and now I am forced to get the problem fixed in order to pass inspection. Thanks GM, just what I need a week before christmas. Only 60,00 miles on car and I have to deal with this. Could possibly be last GM car bought in this house.

I was getting my tank filled with gas and the fuel gauge needle pegged out past full, then bounced down to empty. It did this three times then went back to full. Since then it has continued to bounce around. The only way we knew if we had enough gas was to fill it and use the trip meter. The fuel gauge has ceased to move at all since April 2011. The check engine light has been on continuously as well since the incident. I love the vehicle but it is a major pain to keep track of the fuel when 3 people in the household rely on it. I looked online to see if there was a recall, only to learn this is a common complaint and nothing is being done about it. I priced a new cluster and it was over $500. Needless to say we still have to keep track of the fuel with our trip meter. GM should step up to the plate and fix this issue. They had no problem taking a bailout. My family has been buying GM products for years, however, no one in my family will ever own another GM product if they can't do the right thing for their consumers, and do it now. Not 5 years from now!!

My complaint as with thousands of others......if GMC is acknowledging that they are responsible for the faulty gas sensors, then why do I have to be responsible for half of the bill to correct it ? my car cannot pass my states emissions testing, because as long as the check engine light is on, it will continue to fail...I don't have the money to pay for the repairs. I want GMC to take responsibility for the entire bill...not half !!

Instrument panel fuel level indicator shows incorrectly. At first it would show half tank or more when in fact there was less gas. Now the fuel level indicator shows empty at all times. The audible fuel warning for low fuel also rings constantly. After running out of gas in the middle of nowhere on several occasions the vehicle was taken in to the local dealership. The repair was too costly. We were however charged a $100 fee just for the GMC dealer to look at it. We now track fuel using the trip computer. Look online for some help I was amazed to find out that many, many, many people have and are having the same issue.

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 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'.

I thought my vehicle had a unique problem, after recently being taken advantage of by GMC + their dealer, I have done some research and realize the problem is widespread. The electronic gas gauge + needle stopped working at 90 000. I received a letter stating they would pay for half the repair to the fuel level sensor and I took the vehicle to be repaired on 10/20/11.waited all day and watched the mechanic test drive my vehicle, I was walked to the cashier + paid $146.14, pulled out of parking lot and thought they forgot to reset the computer as gauge + dash were not working.I immediately returned and was told the sensor was working but there was a problem with the cluster panel + that would cost 900.00.this is a major safety hazard and GMC should own up to the defect and recall the vehicles affected. I've run out of gas on several occasions, once on the highway with small children at night.

The fuel gage stopped working and the low fuel light stays on. The check engine light keeps going on and off the port to check engine code does not work. The inside courtesy lights stopped working one back up light will not work the left brake light gets no power and won't work. Only 3 of the 5 speed settings on the fan work. GMC dealer says they can do nothing, and that they do not have other complaints on these problems. However I am able to find thousands of the same complaints online in various consumer sites. GMC won't even return my calls.

The instrument lights regularly blink in and out on my 2005 Envoy. There have even been times when the headlights blink off and on for no known reason. Has happened a few times over the last 3 or 4 years. Scary stuff! plus, I have read on several forums that this is a common problem with these vehicles. One fellow said he took it into the shop and they could not find the problem. Recall - and now the problems with the gas gauge and check engine light. My husband was laid off from his job and we can't even afford the 1/2 that GM is offering to fix the thing in their recall. If they knew it was a failure of their equipment why are they not paying the entire amount?

2005 GMC Envoy XL has several issues with the instrument cluster. The battery and temperature gauges are reading off the scale past their maximum readings. It should also be noted that this vehicle also had issues with the fuel gauge sending unit and the engine thermostat.

July 26, 2011 I filled my vehicle up with gas and noticed that my gas gauge showed that my vehicle was on empty....after driving it for about an hour the gas gauge started working properly. Over the next month it continued to do this off and on. Then I received a letter from GMC stating they are aware of this problem with 2005 GMC Envoy'(weird how the letter appeared as I was starting to have the issue) and that they would pay 50% of my cost to have it repaired at a GMC dealership. Within two weeks my fuel gauge stopped working all together. I never know how much gas I do or do not have in my vehicle. What if I run out of gas in the middle of traffic!! this could be dangerous !! GMC is aware of this problem and should consider it a recall and repair this issue at no cost to the consumer.

Let me start like this. My family including my grandfather always had Chevrolet or GMC cars. I was raised learning how strong they were, smooth driving and extremely comfortable. I bought a Chevy trailblazer 2002 in 2006 which I loved, but unfortunately somebody had crashed and after fixing I sold. Next, I decided to buy an Envoy slt V6 2005 with 27kmiles in 2008, which I have until today and I love so much. Smooth drive, comfortable, powerful, great looking, spacious and great engine. As my grandfather used to say, "son always have a normal maintenance and this car will last forever". I never had any serious problem, except now that the fuel sensor level is dead and I have the chime always signalizing low fuel even if I fill out the tank. Well I wait for more than 3 months filling out the tank and tracking the mileage. 2 weeks ago I received a letter from GMC with my VIN number standing that this is a problem that they find out and they are willing to pay 50% of the cost. I did call them in fact to know the authenticity of the letter and they confirm the issue recommending to take to the dealer. I did, and this problem has a cost equivalent of almost a thousand, which with 50% of discount with the letter will be close to five hundred. GMC is avoiding having this paid 100% since it's a recognized and it should be a recall. I refuse to pay for something that it's a manufacturing defect part. My car has 86K miles today and its still with the problem. I called GMC more than 3 times and the answer is always the same "we'll pay 50% of the total cost". this is ridiculous!!! I want this solved. It's a safety issue !!! I want this paid 100%.

The fuel gauge in my 2005 Envoy XL goes to low fuel anytime after 1/4 tank left. After filling up, it will read low fuel for about 15 miles. It then fluctuates for awhile before settling on what I hope is an accurate reading.

The fuel system started to malfunction around the first week of Sept 2010. I was going on vacation stopped to get gas, after filling up the gas gauge read empty and the warning light came on. After shutting the Envoy off and restarting it the gauge seemed to work. As the days went on the gauge completely quit working and the low fuel light has remained on. I reset my trip meter after every fill up, how annoying. I am not the only consumer with this complaint. I rec'd a letter that GM states its the fuel level sensor. The only fix a new fuel pump from a dealer at 50% off" who can afford dealer prices" this is obviously a defect that GM is failing to own up to. Any help would be appreciated.

Fuel gauge does not go above 1/8 tank. Speedometer "sticks" usually at highway speed and when stopped does not return to zero then when vehicle is moving again the new speed is accumulating on "stuck" speed. Sometimes speedometer "sticks" before reaching steady speed and when vehicle is stopped the reading is below zero in this scenario when the vehicle is moving again the "registered" speed is below actual speed. As I drive 1,000 miles a week, it is quite important to know how much fuel I have in my tank and of course how fast I am traveling.

My fuel gauge stopped working 8 months ago, took to GMC dealer for service estimate. Service manager said these fuel gauges always go out on Envoy and the cost to repair was $578 (plus tax) - I choked and did not get repaired. 3 months later after trying to operate the vehicle without the fuel gauge - it became a nightmare to know if we had gas in the vehicle or not, I took it to an independent repair shop and they said "we see this fuel gauge problem all the time on the Envoy"... they said the GMC parts were a rip-off and expensive, they would have to use GMC parts for the fuel gauge and they quoted $408 (plus tax) for the repair. The service manager for the repair shop said he could not understand why they have not had a recall on this since they have seen hundreds of GMC's with the same problem. He said we may want to wait on the repair to see if GM has a recall. On August 30, I received a written notification from GMC stating an issue with Envoy and the fuel level sensor failure problem; however, GMC stated they would only cover 50% of the cost of repair. What a joke, 50% of a $600 repair bill for a problem they admit in writing is a scam to try and get as many people to pay for the repair ($300) before the gov't. mandates a recall. I called GMC and requested a 100% paid repair and they refused. I will be glad to forward the "fuel sensor failure" letter if you need. Can you please help? the are several hundred thousand owners of GMC Envoy that would be very appreciative - thank you in advance...

Filled vehicle with gas and the fuel gauge registered empty. Fuel gauge no longer works.

"GMC Envoy fuel sensor may fail prematurely". I got this information from GM in a letter. They will pay 1/2 cost to have it replaced if the vehicle is less than 10 years old and has =<120K miles. My vehicle has 148K and is a 2005 model. GM tells me they will not help me with this problem due to the higher miles. I consider the fact that the fuel sensor may read empty even when full or full when in fact the tank is empty to be a safety hazard. I am asking for your help to have GM recall the affected models and repair at no cost to me or the thousands of others who in fact have the same problem. I have never filed a complaint before and hope that I have provided enough information for the board to take positive action.
