The crash that killed Paul Walker and fellow racer and team owner Roger Rodas last year was a tragic, unnecessary thing. But now Rodas’ widow is suing Porsche, claiming the 2005 Carrera GT involved was faulty.

Police reports determined excessive speed was the cause of the crash, and found no evidence of mechanical failure in the Carrera GT. Kristine Rodas, however, has filed suit alleging wrongful death and negligence on the part of Porsche Cars North America.

Rodas’ allegations claim a design flaw in the suspension that caused a malfunction, which in turn resulted in the fatal, fiery crash. In addition, Rodas claims her husband was driving at just 55 mph in the moments before the crash.

Porsche hasn’t yet commented on the lawsuit, which was filed Monday in Los Angeles.
