Fuel gauge problems....my fuel gauge has been floating from 1/2 a tank to empty for the past few weeks and now it the fuel light just stays on even when there is gas in the car. After running for a while the gauge will say there is gas and then it will go back down to empty.
2005 GMC Envoy fuel system complaints
Page 7 of 9: complaints 161 to 190 of 226, newest first, as owners wrote them.
The fuel tank level sensor is defective and could result in a subject vehicle running out of fuel, stall, and being rear ended by another vehicle. The fuel level sending unit has a variable resistor attached to a float inside the fuel tank. As you use fuel, the float changes position (downwards) causing the variable resistor to change value. The change in resistance causes a change in the voltage sent to the fuel gage. My p0463 error is saying that the variable resistor is showing high input, instead of a typical small value. This means that the variable resistor or something else inside the sender unit is causing the ECM to "see" an invalid voltage on the fuel gage circuit. If the voltage is too high then the resistance is too high. Possibly a bad connection between the ecu and the sender or a grounding problem.
Fuel pump not reading gasoline levels causing the gauge in the dash not to work and be on empty at all times. Fuel light also stays on.
I own a 2005 gmc envoy that is having a known problem with the gas gauge and the sender unit. The check engine light also comes on. Apparently numerous customers have been experiencing this same issue on their gm suvs. There should be a recall to fix these known manufacturer faulty workmanship issues.
I'm having the same issue with the fuel gauge on my 2005 gmc envoy. I can register 1/4 a tank but the minute I fill, the gauge drops below empty and the fuel light comes on. I have to drive at least 25 miles to have it register even a 1/4 of a tank and a full 70-85 miles for the gauge to get to show a more accurate level. The mechanic I went to admitted it was the fuel level sensor causing the issue but advised me that I had to replace the entire fuel pump. He quoted $505 for the fuel pump and an additional $360 for the labor its not fixed I don't have the money, what happens if I run out of fuel on the highway or on a tight turn on a hill and the car shuts down and the steering locks? I've read 1000's of complaints and horror stories about this and no recall. This is extremely dangerous!
Defective gas gauge in 2005 envoy, only has 56,000 miles on it. Gauge bounces erratically, and even after filling up the tank the gauge shows empty. Problem just started last week and now happens daily - there is no reliable way to tell how much gas I actually have. Nothing has been done to correct the problem, but I noticed on the internet that this is a wide-spread problem for this vehicle.
One day I filled up my gas gage and it read empty when I drove away. It has read empty ever since with the exception of moving slightly above e for a few min shortly after filling tank. This happened in feb 07 and I just have not had the money to drop on a gas gage so I calculate my miles which is extremely inconvenient and I have run out of gas on several occasions.
Tl*the contact owns a 2005 gmc envoy. The contact stated that the fuel gauge has been misreading the correct amount of fuel that was in the vehicle for approximately four to five months. The vehicle was not taken to the dealer. The manufacturer was not contacted. The failure mileage was 98,000. Updated 02/02/11
Fuel level sensor in my 2005 envoy malfunctioned. Does not register how much fuel is in the tank. This has been an on going problem for months. I noticed an investigation was open in january 2010 but was hoping a recall would have been filed by now. I did research and have noticed there are hundreds and hundreds of the same problem being reported on-line. I just wanted to file my complaint in hopes that something will be done to have this part replaced.
My 2005 gmc envoy is doing the same thing with the fuel system. I will fill up & the gas gauge will tell me there is no gas in it until so many miles and it still wont tell me there is a full tank , it will just creep up a little. Just from reading all the other complaints about the fuel system from 05 & 06 models there should be a recall before someone really gets hurt.
2005 gmc envoy 4.2 l engine 69k on odometer. Re:erratic fuel gauge reading/set code and ran out of fuel on I -95 @ 1/4 tank reading. Filled up and shows less than 1/2 full. Major safety issue local gm dealer says a common problem . Must replace w/ new updated sender at owners cost.
Tl*the contact owns a 2005 gmc envoy. The contact stated that the rear window on the liftgate suddenly exploded. Prior to the failure, the contact noticed that the liftgate would not stay in the up position. The vehicle was taken to a repair shop where it was being repaired. The contact also noticed that the fuel sensor light would illuminate intermittently. The vehicle was repaired by a local mechanic twice (the contact was not sure what type of repair) but the failure continued to occur. The manufacturer had not been notified. The current and failure mileages were approximately 120,000.
Gas gauge stopped working. This has also happened on three other gm SUV's (1999-2005 model years) in my family. Coincidence? No way. There should be a recall. This is a very expensive repair and one consumers should not have to pay for. I have not seen this happen on any other vehicle that I or any member of my family has driven (vw, chrysler, honda, subaru, jeep) but that the same part has failed on four gm SUV's in the same family tells me that this is a wide-spread problem and there is a defect in this part.
For the last few months my 2005 gmc envoy denali has had repeated problems with the fuel gauge. After re-fueling the vehicle, the gauge will go to empty and illuminate the empty tank warning light. The check engine light also comes on. Within a few miles the fuel gauge will begin to fluctuate wildly for a period of time, making it impossible to know how much gas is in it. The fuel gauge sometimes begins to operate again after the car has been driven for a few days. Car has become unsafe because it is difficult to determine how much fuel is in it and empty tank sensor "cries wolf." also, the fuel gauge has begun to register a full tank when really the gas tank is near empty. Once you start driving the fuel gauge begins to fall slowly until about 10 minutes later it finally registers the proper gas level... I've thought my husband filled up the tank and almost run out of gas because the fuel gauge didn't tell me I was out of gas until I was on the highway stuck in traffic - away from a nearby gas station. The trip odometer is not an exact science so it cannot be relied upon. (mpg vary depending out temperature, city vs. Highway miles, MPH, etc). Message boards show that this is a common problem and eventually lead to the car stalling unexpectedly, even during highway travel. See http://www.aboutautomobile.com/complaint/2005/gmc/envoy/fuel+system. "
Sporadic failure of speedometer - registers correctly one moment, or may read 30 MPH or 0 mpg when keeping with the flow of traffic on the interstate. While this does not occur each trip, it does occur several times each week. Fuel gauge malfunction - reads one-half tank at 179 miles; 20 miles later reads one-quarter tank. Issues "fuel level low" warning after refueling and for next 3 to 4 times vehicle is started headlights dim briefly when accelerator is released. Frequent need to replace exterior lamps the problems first manifest in the need to repeatedly change brake and taillight bulbs, and the dimming of the headlights, which continues. Then, sporadically, the speedometer stopped functioning, or only registered a fraction of the speed the vehicle was traveling. After that, at start up, the "fuel level low" warning, which activates when the vehicle determines it has fuel to travel 40 additional miles, started to chime when there was more than one-half tank of fuel. The warning also now issues whenever the vehicle is refueled. The potential failure of the exterior lighting system presents a clear hazard to the occupants of the vehicle and others - the driver wouldn't be able to see where he is going, and other drivers wouldn't be able to see the vehicle heading toward them. The fuel system issues could lead to unexpectedly running out of fuel, creating the potential for a disabled vehicle or its driver being hit by another. In addition, depending on the cause of the malfunction, the vehicle could be susceptible to fire. Without a functioning speedometer, the driver can easily travel too fast for conditions, or endanger himself and others in a construction zone. Currently, until the sporadic problems become regular, the garage will not fix the vehicle.
The fuel gauge became erratic. The first thing that happened was when the fuel tank was filled, the gas gauge went to empty and the fuel light came on as if there were no fuel. It remained that way for some time. It then would fluctuate wildly until a large amount of gas had been used. Now not sure if it is accurate, even though the gas light has gone off and it is no longer displaying as empty.
Out of nowhere my front head lights went out. Its not the fuse or the bulbs, both front low lights went out. The high beams work. There is no power going to the lights and I have to buy a new switch. I also had to replace the engine almost a year ago because the o rings went up. The gas gauge is broken and my passenger window will not go down. I feel so stuck with this car!
The fuel level reads empty when I have just filled the tank. Then when I drive for little while the level reads half full then goes back to empty. There is no way to tell how much gas is in the tank. The fuel level gauge is sometimes moving back fast to empty while driving.
Tl* the contact owns a 2006 gmc envoy. The contact stated the fuel level indicator would inaccurately read fuel levels and would often read empty when the tank was full. When this happened, the check engine light would illuminate on the dashboard. The manufacturer was contacted and advised taking the vehicle to the dealer for diagnostic testing. The vehicle was not taken to the dealer nor repaired. The failure and current mileages were approximately 40,000.
2005 gmc envoy gas gauge shows empty with light on even when the tank is full of gas.
Fuel sensor started messing up, not reading gas correctly. Now if will not move when gas is filled up.
Fuel gauge inop.
2005 envoy, fuel gauge suddenly became erratic, reading empty when tank was full. Initially, after filling tank, fuel gauge would continue to read empty until driven approximately 20-25 miles. Now rarely reads above empty. Gas gauge is now completely ineffective, high likelihood of running the car out of gas in a dangerous situation.
Fuel gauge not working correct ran out of gas.
Defective fuel gauge that swings between full and empty - this is the second time this occurred with this vehicle. The first required a replacement of the in tank sending unit.
When I fill it completely full with gas on my 2005 envoy it says that its empty. I have to drive almost 50 miles or more for it to register right. Also one time when I was backing out of a parking stall it just quit not very safe I could have been hit by another car.
In reference to dp10-001. I have a 2005 gmc envoy that has an erratic gas gauge as well. After re-fueling the vehicle, the gauge will go to empty and illuminate the empty tank warning light. After driving about 20 miles, the gauge will return to the full position, but will fluctuate occasionally. I have had the problem diagnosed as possible faulty sending unit, faulty gauge and faulty sensors on the fuel pump assembly.
Item 1: fuel gage located on instrument panel reads empty after tank is filled to maximum, light goes on indicating tank soon to be empty, after fuel is added gage fluctuates often from empty to 3/4 filled then 1/2 tank then back to empty reading which makes me constantly refueling tank .this problem occurs while vehicle is in operation..item 2 speedometer fluctuates reading 80 miles in speed actually no such speed is being driven then returns to zero miles continues to move so erratically. Dealer service advisor stated problem is the fuel sensor suppressor located in the fuel tank, states tank must be dropped down during repair, recommended should replace fuel pump now since tank was accessible good opportunity in replacing also this item and I would be covered with lifetime warranty in future if need of repair. Fuel pump price $480.00. I declined repair only fuel sensor/suppressor, check speedometer gage. Service advisor stated this item was not recalled or covered, this financially sets me back now since on a set income.this because myself a disabled vietnam veteran. Hope no more problems would be found on my vehicle these. This part alone would cost $380.00 not including repair charges. Vehicle was in for maintenance service oil change, radiator flush, tune up, transmission service. Personally always have recommend gm vehicles/products to all associates, family, friends & acquaintances. I own a classic original 1947 pontiac 8 flathead, 4 door streamliner.today just disappointed with these issues may have resulted to accidents leading to bodily injuries, or fatalities. Complaints have been filed with this model among other issues.& concerns. Would appreciate investigation the many complaints on file thru years 2001-2008 make & models also set as priority before any future accidents or deaths occur. With quick response & action gmc can avoid many bad reactions against their history of great quality and it's excellent commitment to customer satisfaction.
