I posted this over on The Mustang Source and wanted to see if anyone over here has seen these problems. Below is what I posted over there. To sum it up, I have been contacted on the forum by a Ford rep as well as by phone.
Post 1: My new 2011 GT last week and have put about 200 miles on it since I got it. It did something wierd tonight and I was wondering if anyone else has seen this. My DTE in my info center said about 130 +/- and I had between 1/4 and 1/2tank of gas left. I was driving down the road and all of a sudden, my DTE goes to 4 miles until empty and my gauge goes to E and turns red. Then, I immediately put $20 in premium in it because I wasn't sure of WTF was going on and then my gauge says almost full and my DTE is up to around 250-280 (cant remember specifics). Has anyone seen this on the new ones? I had an '08 for just over 2 years and never saw this.
Post 2: I just wanted to update everyone on this. I did get a call from a Ford rep last Thursday and told her I would be contacting my local dealership to have them look at the problem. She was super nice!!
Now, yesterday, I had more issues with the car. When I got out of the car on Christmas Eve night, my DTE read in the neighborhood of 115 until empty and my gauge was around 3/8 full. I got in the car yesterday and let the car warm up for about 15 minutes (we got some snow). The gauge said EMPTY and the DTE read 4 left. So, I ignored that and drove on. I drove about 20 miles and ran out of gas on the side of the snow covered 2 lane road. I had my wife following me and she went back to get some gas. I used the little funnel included in the trunk and put roughly 2.5 gallons in the car. The car started right up adn I drove about 20 miles to the gas station and was going to fill up. Well, it would ONLY hold about 8.5 gallons. So, my math tells me it would ONLY hold about 11 gallons when its a 16 (??) gallon tank. What gives here.
Then, this morning, when I got in the car, my info center told me to check my fuel filler door.
I have an appointment Wed morning to have Ford look at this. I'll report back what happens out of that unless I have to postpone the appointment; which is a whole different story!

Got my fuel pump replaced today and drove about 40 miles since. My DTE reads around 80-90 which is as low as it has ever read so I think my problem is fixed.... That one anyway! When the dealer tech was removing the fuel pump, they splattered gas on the back of my driver's side back seat and now they have to replace the leather as it ruined it.
Steven79, from what I understand, they have to remove the back seat bottom and then you can get to it but im not certain. I don't know how they got gas on the seat bit they did. The TSB definitely fixed my problem though.
Thank you Zach, then the question would be.. can this entire situation be remedied if I never let the fuel drop under half a tank?
My situation occurred today and it was EXACTLY as you described.
However, I am very hesitant to let them remove my back seats, etc... I am willing to just never drive more than 150 miles before refilling (as this is not a daily driver car).
So I wonder if I kept the tank always over half full, if the problem is "remedied".?
They only had to take out the seat bottoms and not the backs too. Im not sure how the tank fills up, but I would probably just get it fixed. I dont know what the long term effects are of the bad pump; we are finding out what the short term effects are though.
My thought is that we have new cars that should act correctly and if you have something defective under the TSB, you deserve to have it in correct working order. After all, these are $30k+ cars! I'd fix it if I were you.
Just wanted to post up about today. As you know, I had my fuel pump replaced last week. I ran thru 1 tank of gas and it went down and did the normal 50 miles to empty so I filled it up a little later. Now, today, I had around 80-85 miles to empty when my DTE meter AGAIN jumped to 4 miles to empty and my gage also went from 3/8 to red. Looks like I will be calling Ford AGAIN about this. I hope the new pump they are puting in cars is not the same pump with no revisions as the one that was originally in our cars!
I have an appointment at 8 tomorrow mornig to take my car back to the dealership. Ford has instructed them to run some diagnostics on my instrument cluster and electronics. I think I just lucked up and got another bad pump but maybe im wrong!
The local dealer put a second new fuel pump in last wednesday. I have run thru 1 tank of gas and everything worked as it should. Im waiting to finish off my second tank to see if the problem reoccurs. With the first replacemnt pump, eveything worked fine on the first tank but the second tank showed the problem. I've got about 150 miles to empty right now so it will be this weekend before I finish it off...hopefully!
Ugh, I had this happen to me the other day. Cruising down the highway at half a tank, and next thing i know, fuel light is on, needle at E and its telling me i have 4 miles to empty. I've only had the car a week and that was the only time fuel has been that low. Will it happen again if it gets to 1/2? Should I take a preemptive measure and try to get Ford to go ahead and replace the part, even though it has only happened once?
I went through this hell on mine. They changed the module per the tsb, that worked for 1 tank of gas, then came back. Then they changed it again, along with the module on the other side (there are 2) still fail, strike 2. After much diagnosis, and getting Ford involved, they changed the instrument cluster, problem solved.
BTW, it's not just a gauge issue, if you push it and keep driving for about 10 miles after the gauge drops to zero the car will die (with 6 gal still in the tank )
Apparently the computer gets confused and decides not to play anymore.
Nothing like standing on the side of the turnpike next to your brand new car.
