2000 Saab 95 Fuel System problems

I hear fuel sloshing/thunking sound when the tank is 1/2-3/4 full. I am not sure if this is a safety hazard, but it concerns me. The mfg. Has told me it is not a safety issue.

Fuel tank is defective--fuel rushes to front of tank upon braking and thunks the entire vehicle. This stress on the fuel tank could pose a threat, such as a fuel explosion, in a crash. Problem exists when tank is 1/2 to 3/4 full. Saab is aware of the problem, and states that it is caused by compliance with ca emissions standards. No other manufacturers have had such problems in complying with ca emissions. I have spoken by the internet with over 10 other saab 9-5 owners who all report the same problem. This is a design defect, not an individual complaint. *Ak

The fuel tank makes a unbearable loud noise. The fuel is banging against the walls of the tank which could eventually rupture the tank or loosen the connecting components. *Ak
