I've been having quite the month with my car. First indication that there was anything wrong was at the end of June, when my car lost power and stalled a few blocks from my house. Tried to restart it and it just cranked away, shaking pretty violently in the process. I called roadside assistance and had it towed to the dealer, where they discovered it was completely out of fuel. I was incredulous because the gauge was reading 1/4 full at the time it stalled. Initially, they said they couldn't find anything wrong with it, and -surprise, surprise- sent me on my way. I was now watching the gauge like a hawk. The first thing I noticed was that it stayed on full for the first half of the tank, and would then drift from 3/4 to full. I took it back to the dealer twice more, and they eventually figured out that the fuel tank was warped, and replaced it. All seemed well; when I picked it up, the gauge was actually sitting in the red, (was almost empty), and I filled it up. Back to the same old, same old. Stayed showing full for over 100 miles on the trip odo. Called the dealer back, and was told to bring it in.
At this point, with 160 miles on the tank, they had it overnight, and called me back and said nothing was wrong, and the reading was correct. They gave it back to me with the gauge showing about 2/5 full. Last night, when driving to work, (11 mile trip, mostly freeway) Gauge started at 1/4 full, and during my time on the freeway started to creep up to 1/2. Then, while going about 60 miles per hour on I-43 just south of downtown Milwaukee, the thing lost power again. I had to cut across four lanes of traffic and made it to the breakdown lane just as the engine shut off. (Narrowly avoided a serious crash with a black suburban - driver gave me the one fingered salute as she went by) Roadside assistance guy gave me two gallons of gas, and it started right up. Gauge still showed half full!
So, today I guess it's back to the dealer to throw my keys at the guy and tell him to keep the car until they're sure it's fixed. I love this car, and I'm a loyal Ford customer, but I'm tearing my hair out over this.
