What's wrong, in plain English
On some BMW Z4 and Toyota Supra vehicles, the weld joining the two halves of the fuel tank may not have been done well enough, which can cause the weld to fail over time. If the weld fails, fuel could leak from the tank. If that leaking fuel comes into contact with something that can ignite it, it increases the risk of a fire.
