German auto giant BMW Group on Friday began recalling more than 21,000 luxury sedans in China to fix a faulty brake system, while British carmaker Jaguar Land Rover recalled 30 Discovery 3 TDV6 diesel vehicles, China's quality watchdog said Friday.

BMW's recalled vehicles in China included 21,383 imported BMW 5, 6 and 7 Series autos manufactured between Dec. 14, 2001, and Nov. 23, 2009, along with 388 Rolls-Royce Phantom luxury cars manufactured between Jan. 1, 2003, and Nov. 30, 2009, according to a statement on the website of the General Administration of Quality Supervision, Inspection and Quarantine (GAQSIQ).

BMW's recall is to fix faulty brake boosters, which may be contaminated by lubrication inside the vacuum pump and could cause the failure of the brake boosting function, according to the GAQSIQ statement.

Jaguar Land Rover's recalls in China, much smaller in scale, covered 30 units of imported Discovery 3 TDV6 diesel vehicles which have defective fore bearing lubrication inside the high-pressure fuel pump, according to a separate GAQSIQ statement.

The Jaguar vehicle defect may cause a fuel leak or even fire under extreme conditions and is a potential safety hazard, according to GAQSIQ.
