Ford, which owns Jaguar and Land Rover, has refused to be drawn on whether a review of staff costs outside its North American heartland would lead to job cuts in the UK.
The company said it was "evaluating options for reducing personnel-related costs outside of North America" after warning on profits for the second time in three months.
The jobs fears come as Ford revealed it would cut its North American headcount by 1,700 on top of the 1,000 job losses announced in April.
A spokesman for Jaguar and Land Rover in the Midlands - part of Ford's Premier Automotive Group - said he had nothing to add to Ford's announcement, although he did point out that restructuring of Jaguar production in the region was in the pipeline and Land Rover had bulging order books.
However, both manufacturers have been under the Ford microscope, with Jaguar under pressure to stem heavy financial losses and Land Rover under orders to improve the build quality of its off-roaders.
Earlier this year, The Birmingham Post reported how PAG, plunged into the red in the first quarter.
The luxury car operation, which also takes in Aston Martin and Volvo, made a loss of $55 million (£29 million) between January and March compared with a pretax profit of $33 million (£17 million) in the same period last year.
The deficit, which was incurred on sales 12 per cent up at $7.6 billion (£4 billion), was mainly due to unfavourable exchange rates, but had been offset partially by lower costs. The strong pound has proved bad news for Jaguar and Land Rover, both of which rely heavily on the US for their earnings.
A Ford spokesman said: "If there are actions to be taken in Europe at a later date then we will go into that then."
Vehicle sales are now expected to be so poor in North America that Ford cut its predictions for profits to between $1(55p) and $1.25 (68p) a share.
Managers of Ford's global operations are sharing the pain after being told that they will not receive any bonuses for this year.
Don Leclair, executive vice president and chief financial officer, said the moves have been made because of the challenges facing the car giant had continued to mount.
Ford is not alone in suffering from a downturn in the North American market as General Motors has also warned on profits this year. It also comes in the year that MG Rover collapsed.
Surging oil prices have acted as a deterrent while fears of a global economic downturn are weighing on the confidence of consumers, forcing car firms to offer incentives and promotions to shift existing stock.
In the Midlands, production of the top of the range Jaguar XJ saloon and the XK sports cars will move to Birmingham when production ends at Browns Lane, Coventry, at the end of July.
They will be built at Castle Bromwich alongside the Stype saloon, with production expected to being in midtolate August.
