sailor I see you've read up on the potential issues with loose nozzle tips. The solution to problems from dented nozzles (stainless steel cap) has ended up having possible problems of it's own when they get loose.

Automatic shutoff valves are quite delicate, they have to sense air pressure change in the fill pipe. Actually amazing that they work as well as they do considering the beating they take daily.

The new overflow drain location goes with the new "capless" fill system, an obvious surprise that's probably not mentioned (or glossed over) in the manual no-one reads thoroughly unless looking for info.. Convenience features - come with new problems of their own.

Thanks for the reply Sailor. That thought occurred to me yesterday afternoon when I noticed the gauge had actually started moving. As I drove to the dealer this morning for my routine service, noticed it now appears to be back within the normal reading for the amount of miles I've driven since my last fill up.

As such, when I went in today, I mentioned what happened with the overfill, but that I was no longer concerned about the fuel gauge. Service advisor repeated exactly what you just said about slow response due to the excess gas in the tank. I did have them conduct a visual inspection of the fuel tank, filler, and other components they could easily access as well. No leaks, broken parts, wear, etc..

So, for now I'm going on the theory that the pump nozzle shutoff was defective, and will be extra careful when inserting gas nozzles in the future. Service advisor noted that as well, and told me that Ford Engineering had actually sent out a memo to all service departments indicating the tendency of gas nozzles to be defective. He also told me that one of their customers had an incident where a nozzle got stuck in the fuel filler. Similar to the incidents described in other posts here, except in this case, the gas station folks were able to remove the nozzle without damaging the fuel filler or denting the person's car.

FWIW, the first car I regularly drove (my parent's 75 Buick Century wagon) had a very erratic and mostly unreliable fuel gauge - hence my sensitivity to possible fuel gauge problems.

stevetimm The tank overfill I mentioned in a previous post last week has apparently affected the fuel gauge on my 2012 SE as well. Have driven the car about 110 miles since the incident, and the gauge has now only just begun to drop to about midway between full and 3/4 full.

The Average MPG and Miles To Empty displays are still working properly (consistent readings based on my past driving - I reset the Average MPG and Trip Odometer after every fillup), so I'm not too worried about the potential of running out of gas ("knocks wood"). However, I'm planning to take a trip to Western Pennsylvania during Labor Day week, so having an unreliable fuel gauge is something I really don't want to deal with.

Taking the car in for routine service tomorrow morning, and I've already informed my service advisor of this problem. Crossing my fingers that resolution won't be a biggie.

Hello cymlee,

I'd like to loop in touch with your regional customer service manager, who is in the best position to assist. Please send me a private message with your full name, best daytime phone number, VIN, mileage, and servicing dealership.

sailor Trip computers aren't the most accurate, with only a short time sample to figure from their "estimate" of what will happen in the future can be wildly off.

To demonstrate with a scenario that's a simplification of what happened to yours today.

Idle 10 min. (Zero MPG for that time) drive 10 min. at 30 MPG. Average mileage since filled? 15 MPG. Computer figures range to empty at 15 MPG, range looks very short. When you started out, it might be figuring 15 gal. at 30 MPG for 450 miles. After idling and the short trip, it refigures range at 15 MPG for the rest of the tankful - 14.5 gal. @ 15 MPG would be 217 miles.

Now I'm guessing it started out from zero when the new battery was installed, so there isn't much history in the system to base an MPG estimate on. Given a longer history in the system, short term MPG won't affect the long term estimate as much. For now, all it knows is that you haven't gone far for the fuel used.

If your system lets you flip to an average MPG readout, I'm betting that will be a low number confirming my guess.

Good luck with it, I'm hoping all is OK for you & the system just needs more info. to give you a better estimate.

(Computers are dumb, GIGO is my bet on the current range estimate)

cymlee I got a 2010 Ford Focus back in June and had no problems until recently. Last week my car wouldn't start. I got a jump start and once the car started up, the miles to empty read 0 and the low fuel light was on. When I parked the car earlier that day, I had 80 miles to empty. After a few minutes the miles to empty when up, but it still was inaccurate. The next day I took the car into the dealer, where they replaced the battery and told me to fill up my car and then reset the fuel economy. I reset the mileage and my car had more than 450 miles to empty, which has never happened. All was well, until yesterday and today. When I went to start my this morning I had 415 miles to e. After only letting the car run for a few minutes, it went down to 410 and continued to rapidly decrease until I got to work, which is less than 10 miles away. I now have 298 miles to e and I have not driven anywhere near 150 miles in a week. I'm not even sure how much gas is still in my car at this point because when I start it tomorrow, the reading will probably have changed again. I'm taking it into the dealer in the morning. I just wish the mechanics would've listened to me when I brought the car in last week, because the issue is still present.

This is my first Ford in 35 years and probably a short lived last Ford as I have had it in to the dealer 5 times in the first 3 months of ownership.... Quality is... Job None! Absolutely love the way the car drives but it is the most unrelieable/possessed car I have ever owned by a longshot!!!! I used to complain about people being dangerous drivers... now I worry about my car trying to kill me... seriously!

Ok... rant over! hahaha

Anybody out there have a similar issue and actually get a permanent fix so I don't run out of gas again in the middle of rush hour again? Thanks in advance....
After my last incident in August, the dealer kept my car for over a week. They basically replaced most of the fuel systems. The culprit was stuck purge valves. They also discovered that when the purge valves initially collapsed the fuel tank, the fuel pump was damaged. In the end, they replaced the purge valves, fuel tank, sending unit, and fuel pump. Then they filled it and drove it until empty to ensure it was fixed. And it is. No problems since then, but my confidence in Ford has taken a huge hit. Not even my horrible 1999 Explorer ever tried to kill me.
