Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Gas tank leaks when filled completely, indicating a leak at the top of the tank or gas lines going into the tank. I have contacted ford several times but they say it is not covered. I do not believe the leak was caused by a road hazard since it is at the top of the tank. Ford said they will not cover the repair since it has not been recalled. They did agree it is a serious safety hazard.”
