BMW has announced it will recall about 350,000 luxury cars worldwide because of a problem with brakes.
The German firm said the recall was due to a fault with the power-braking system but the cars were not unsafe.
The recall affects V8 and V12-powered BMW 5 Series, 6 Series, 7 Series, and Rolls-Royce models produced between July 2001 and November 2009.
Of the total, 11,427 cars - including 905 Rolls-Royces - are in the UK, and 198,000 in the US.
Globally, 348,000 BMWs are affected, plus a further 5,800 Rolls-Royces.
"In the affected vehicles, a leak may develop in the power braking system, potentially causing a vacuum loss and consequent reduction of power braking assistance," said the company in a statement.
However, mechanical braking is still available to slow and stop the vehicle, and there have been no reported accidents or injuries.
A BMW spokesman told the BBC that the problem was identified via feedback from routine vehicle servicing, and that the recall is entirely voluntary.
BMW's share price dropped 3% following the news, to below 50 euros.
However, the company's stock remains well up for the year, having rallied from a price of 30 euros in March.
The news comes a day after the US National Highway Traffic Safety Administration said it was investigating a potential power steering problem with the Mini - another brand owned by BMW.
It also comes a day after BMW's chairman, Norbert Reithofer, had his contract extended by six years.
