2009 Ford F-150: wrong fuel gauge reading

Filed Dec 21, 2018 · Fuel system · 71,521 miles · OH

Gas gauge suddenly doesn't register correctly. Only shows approximate three quarters tank when tank is fully filled. When registering one quarter tank only takes $15- to $16 to refuel. Repair shops have not been able to determine cause. What can be the cause.

This has occurred many times. The vehicle stalls when slowing down due to the fuel pump inside the fuel tank getting bent upward due to the tank collapsing on itself because it is not designed to vent properly. I have already replaced the fuel pump but it only corrected the problem temporarily because it has been bent as well over a short period of time. The gas gauge reads improperly as well due to the pump not reaching the bottom of the tank. I can only fit about 17 gallons into a 30 gallon tank upon refilling. The stalling that this causes has almost caused me to have multiple accidents. I have researched this problem and have found many other owners to have the same problem and have had accidents. Ford refuses to correct the problem without charging. It is very expensive to have the fuel pump replaced and that does not fix the problem. This is a design problem that ford needs to repair. Please require ford to recall and fix this design flaw before someone else is killed or injured.

First, the fuel door fell off the truck. Later that evening I heard a weird suction sound coming from the fuel door area. It began to idle rough, then would not want to start after fill ups. When you would stick the gas nozzle in the tank a loud "whoosh" sound would emit as it relieved pressure. My gas gauge stopped functioning and all of these issues eventually leading to the tank imploding/collapsing on itself. This bent the fuel pump and gas gauge inside the tank. I paid out of pocket to have it fixed because the ford dealership told me the warranty only "covered moving parts". I asked if the fuel gauge float and fuel pump moved. They enjoyed my rhetoric, but declined to fix the problem. They only replaced a sensor that threw a lean bank one code and caused the check engine light to come on. I drove it for the next year or so using the odometer to tell me when to fill up as my gas gauge no longer worked.. Fast forward a year and a half, and running out of gas 3 or 4 times, and it has done the same thing to me again. I just paid $972.19 to a private garage to replace the fuel pump, but I only got a 90 day warranty on the work and no guarantee that this issue will not happen again. When I googled the make and model of the truck I found all kinds of information about people having the same problem, yet ford acted like they have never heard of this before. I understand I am responsible for keeping the truck running, but nothing about the way I operate the vehicle made it do this. If I get in a wreck, I should pay to fix it. This is a design flaw and should be recalled. Btw I was doing 70 MPH on the interstate when it shut down most recently and traffic had me boxed in. It nearly caused a collision just getting it off the road. Had I died, no one would have questioned what caused the accident.

No problems until about 60,000 miles. Then one day, while stopped, the truck suddenly died, the check engine light came on, and the gas gauge would indicated a quarter tank when the tank was actually full. All of this happened at the same time. I had two oxygen sensors replaced (about $400) to clear the check engine light and the fuel pump replaced (about $700) on the recommendation of the ford service department to cure the gas gauge problem. While turning across oncoming traffic, the vehicle has died and was hard to steer. Oncoming cars had to brake rapidly as I have had a hard time steering with no power. This has now happened numerous times. The truck dies or runs very rough and nearly stalls almost every time I drive it more than a mile or so. There is no check engine code and the dealer stated it could not be duplicated when I took it in for evaluation. This has the potential for creating a dangerous situation. I would fix this issue if it could be identified.

The fan blower speed control stuck on high only and was replaced 09/2011. The vehicle kept stalling out upon deceleration going down the road. With loss of power steering and power brakes when this happens. Could be going 30 MPH or 60 MPH. When get motor is started again it usually runs rough. The left oxygen sensor code was on so this was replaced. 11/2011 the fuel gauge also stopped reading fuel in the tank when this happens. Replaced fuel pump in tank, fuel filter, fuel power module, all was fine for three weeks. Truck dies 8 times today and all the same problems are back. Engine light on, fuel gauge stopped working, truck runs rough for awhile when restarted then clears up. Engine light now stays on and fuel gauge will read 1/2 tank when it is full. 36 gal tank. 11/22/2011.
