On Tuesday a supplier petitioned a Swedish court to declare National Electric Vehicle of Sweden (Nevs) bankrupt.
Labo Test, which supplies test equipment for car parts, said Nevs had failed to pay bills of 150,000 kronor ($22,000) since February.
Nevs spokesman Mikael Ostlund didn't immediately answer a request for comment.
The company, owned by a Hong Kong-based group, bought Saab out of bankruptcy last year after a failed attempt to revive the brand by Spyker Cars of the Netherlands.
Though its plan was to make electric cars, Nevs started off with gasoline-fuelled models to get production going immediately.
