Ten problems related to tank mounting have been reported for the 2006 GMC Envoy. The most recently reported issues are listed below.
Noticed that the fuel gauge for the past week has been acting very strange. I had a half tank of gas and drive very little daily (maybe 10 miles) and in 3 days it went from 1/2 tank to empty. I actually thought my gas was leaking out, but no gas spots or leaks. Now, it was on empty, light came on, and started to bing, and the engine light is on also. I filled the car up and fuel light is still on and so is the engine light. Indicating a problem at the fuel gage. I love this car, I have never loved a car more. . . But, now reading all the huge number of people having the same problems. . . And the cost to have it fixed is wayyyyyyyyy more than I can pay or afford. I have been trying to figure out how I am going to pay the first half of my re taxes and my home owners insurance, I used to work for years with auto dealers and with this amount of complaints, the manufacture normally does a recall and fixes this problem. My concern is, if I keep driving it without getting it fixed will I create more problems and the bigger problem is how do I know when I am on empty since it is now always on empty??????.
Fuel gauge is not working properly on my vehicle. It stays on "e" when there is plenty of gasoline in the car. There have been several complaints about this that I have seen on websites. Ocassionally the gauge willl move up but then go back to "e". I went to dealer and they said it is a bad fuel senor guage which is in the gasoline tank. Seems like this is a common issue and could cause other problems. The fuel gauge has been like that for over 6 months, as the cost was astronomical and I believe there should be a recall. Additionally, recently my oil pressure gauge has shown the max amount and then last night it went down to the lowest amount on the instrument panel. It goes back and forth from high to low and the oil pressure low light comes on the instrument panel and then goes off. It says to stop engine. There does not appear to be anything physically wrong with my engine and I will be taking it to the dealer tomorrow to confirm that. I believe both of these issues are caused by a faulty instrument panel or electrical system included in gm's models. I have a family member with an older GMC SUV with similar issues and they also had issues with a GMC truck they used to have but got rid of it, due to the malfunctions. Seems like a very common issue that should be resolved by ge.
A couple months ago my gas gauge started to act up. It was not registering the amount of gas in my fuel tank. I have already been stranded due to no gas and I just don't want it to happen at a critical time and cause and accident! I have a 2006 GMC Envoy. This issue needs to be addressed and handled.
2006 GMC Envoy: fuel tank sensor shows fuel then doesn't, bounces back & forth. I drive in the mountains and am now very paranoid that my car will run out of gas and leave me stranded on a mountain highway. . . . Very dangerous. Mechanic says error code is po463. I am so afraid to drive my car alone now. . . So I stop gong down & then back up the hill just in case I can put in more gasoline. My car also has a drivers' side master control window that burned. . . . Could have started a fire. When my mechanic took it apart, he showed me the burned areas,. . . Smells bad.
We have a 2006 GMC Envoy that has been experiencing fuel gauge issues. This has caused us to run out of fuel and now not be able to rely on the amount of fuel remaining. This shows both on the analog gauge and the mile remaining section of the suvs dash display system. After filling the fuel tank the guage goes to empty then jumps to full then drops down to empty and then the check engine light goes on. This issue is constant now and creates a distrust in the status of the vehilcle. . I have read many complaints online and no response to fix this persistent issue by GMC.
After filling the vehicle tank with gasoline, I started the vehicle and the gas gage immediately went to empty and the alarm sounded. The gage recovered after the level dropped to about 1/3 and operated correctly for the rest of the tank. Then the gage became more erratic and has no indication of the amount in the tank. I understand that this has been a common issue with the 2006 Envoy and is very expensive to repair as they must replace the fuel pump and sending unit in the tank.
Gas tank sensor failed October 2010 on 2006 GMC Envoy slt. Shows tank empty regardless of amount of gas put in tank which results in the the 'check engine' light coming on 99% of the time. Cost to repair is approximately $600. Mileage on car was about 60,000 miles.
My fuel level sensor is failing to tell me the true amount of fuel left in the tank. I often says that the tank is empty but many times it changes from 3/4 full to 1/2 full and sometimes back up to full then empty. I replaced the fuel level sensor and is now working. I do have the old sensor available. 2006 Envoy denali xl.
The contact owns a 2006 GMC Envoy denali. The contact stated that in October 2009, he noticed that the fuel gauge would "flutter" and register that it was empty when he added gasoline to the fuel tank. After consuming five to seven gallons of fuel, the fuel gauge would begin working normal until the it was time to add the maximum amount of fuel in the tank. The check engine light also illuminated and the heater would blow cold air on the driver side and hot air on the passenger side. The vehicle was taken to the dealer where the sending unit in the fuel tank was replaced and the heater was reprogrammed; however, the heater still did not function properly. The VIN was unavailable. The failure mileage was approximately 40,000. The current mileage was approximately 46,000.
Had just filled the fuel tank and had driven about 5 miles when the check engine light came on and the fuel gauge had gone down to the empty mark setting off the low fuel alarm. Pulled off the road to check the gas cap, and it was installed, but loose. Discovered the o ring gasket was missing from cap. Drove another 10 miles and went to auto parts store and purchased a replacement cap. Engine check light extinguished, but fuel gauge sweeps back and forth, sometimes setting off low fuel alarm. Will call dealer on Monday to see if there is a sb for this. Almost out of warranty.
