Robert Hendry's tenure as chairman of Adam Opel AG is back in question following fresh press reports that two members of Opel's supervisory board called for a European to replace him.
Opel's 20-member supervisory board has the power to replace the chairman, although parent General Motors has traditionally handled appointments.
Hendry was vacationing in California last week and unavailable for comment.
Hendry, 56, was brought in as chairman of GM's German subsidiary two years ago with a mandate to fix Opel's sagging market share and red ink. The American had been in charge of Saab Automobile AB in Sweden.
Since March, there has been public speculation that Hendry would step down.
German newspapers have reported an imminent appointment of Carl-Peter Forster, former BMW production czar, as Hendry's replacement.
GM spokesmen and Hendry's boss, GM Europe President Michael Burns, have issued public statements of support. But Hendry himself has signaled he is ready to move on. He told in October: 'I would like to do something different, but the time has not come yet.'
