Initially, when the car was filled with fuel, it immediately indicated that the car was empty and the engine light came on. Once you used a couple of gallons the fuel gauge began working and the engine light went off. Just recently the system is not correcting itself and the fuel gauge will constantly go between full and empty so I never know how much fuel I have in it. Also the engine light is remaining on.

What owners say
Initially, when the car was filled with fuel, the fuel gauge would automatically go to empty and the engine light would come on. After driving several miles, the gauge would correct itself and the engine light would go off. After months of this, the system does not correct itself and I never know how much gas I have - it constantly goes from full to empty.
When starting my vehicle and start to drive I notice 2 check engine lights pop on. One engine light has a arrow pointing down and the other just have the engine light symbol and the my speed starts to reduce a lot. I will pull over to the side of the road shut the car off wait for 5-10 minutes and crank it up and after maybe 15-20 minutes of driving it pops back on. I've had the mechanic to diagnostic machine and he has said the throttle body needs changing, had that done and the same problem came back. So I had my old one put back on and then the mechanic say maybe it's the gas pedal sensor. Had that changed and the problem is still their. I love my truck but I don't have the money to kep trying to fix this problem. I need help, from someone, please
Tl* the contact owns a 2006 gmc envoy denali. The contact stated while driving at an unknown speed, the steering wheel became difficult to manuever. The contact mentioned while starting the vehicle there was intermittently roaring noise and the check engine light illuminated. The vehicle was taken to a dealer however, the technician was unable to diagnose the failure. The manufacturer was not made aware of the failure. The failure mileage was 45,000 and the current mileage was 60,000.
After driving approximately 20 miles on cruise control I tapped the brakes to disengage the cruise control. The vehicle dramatically lost power and the check engine light came on. I was able to avoid other traffic and pull over on the freeway, I then drove off the freeway on the shoulder and into the nearest gm dealer at maximum speed of approximately 30 MPH. The problem was diagnosed several times resulting in rewiring of the throttle body connector and finally replacement of the throttle body after the third incident of the same issue. Loss of power and unable to proceed at more than about 30 MPH.
Tl* the contact owns a 2006 gmc envoy denali. The contact stated that after refueling, the fuel gauge went to empty and the check engine light illuminated. The contact was told at a parts store that the fuel sending sensor failed. The vehicle was not repaired. The failure mileage was 66,000 and the current mileage was 67,000.
I received a letter from gmc stating that they had a known issue with the fuel sensor on my vehicle, would pay half to have it repaired. Within two weeks my fuel sensor gauge is floating from full to empty and the check engine light for emission comes on when the float starts. Why must I pay for repairs for something that is obviously defect on the vehicle if all of the other complaint are anything to go by?!
Hi I have an 07 envoy denali and I have a problem with my engine light being on. Took it to get a diagnostic check and the throttle position sensor needs to be replaced. I have replaced my altenator and battery in 2010. Now my bags that lifts the truck struggle and does not work on a daily basis, my lights may not come on and the oil gauge light is on (and also dropped down to zero) and service stabilitrak light stays on. Two years ago I replace the motor that controls the window that cost me around $500 bucks. I live in dc and I cannot pass inspection because of the engine light is on. On edmunds.com there are many tsb issued for my vehicle purchased in that year.
