Leaky fuel tank. Strong smell of leaky fuel. Worried that vehicle might catch fire. Took it into my local oil change place and they could not find leak. I can see a puddle of fuel on my driveway - about 2-3 feet round. Believe fuel tank has corroded. But I am told the tank is made of plastic. Looked up 2 other NHTSA complaints with similar failure complaints. Vehicle has 152,000 miles.
Gas tank leaks at the seam.

This is a huge safety issue we have run out of gas on the freeway two times the gauge will say 70 miles to empty and 30 seconds later goes to zero the car runs out if gas in the car shut down on the freeway with my children in the car I have also run out of gas on the street I took it and pay $200 to a mechanic who is not able to fix it the Ford dealer said they can't figure out what's wrong with it but recommended a $700 fuel sending unit howeverthey were unsure if this would fix the problem this is a major safety issue a time hassle and very stressful on a four-year-old car that I've taken very good care of. When this happens and I go to fill up the tank the gas tank isn't actually empty even though it says it is and the car shuts down.
