BMW (ETR: BMW) has extended a recall of 312,000 cars in the UK, which have been found to stall while being driven.

The group initially recalled 36,410 last year over safety issues but has extended it after the BBC’s Watchdog identified similar issues in cars that were not originally covered.

“BMW is expanding the existing B+ battery connector UK recall. This relates to predecessor generations of the 1 Series, 3 Series, Z4 and X1 built between March 2007 and September 2011,” said a spokesperson.

“BMW will be contacting all affected customers by post advising them of how they can book their car in to have the work carried out. We will commence contacting affected customers in the next three weeks.”

An investigation by the BBC Watchdog found that the fault could affect a wider number of cars.

The initial recall was launched following the death of Narayan Gurung, who died on Christmas day in 2016 after he crashed into a tree to avoid a broken-down BMW in Surrey.

“We now recognise that there may have been some cases of similar power supply issues in vehicles not covered by the original recall,” said BMW, in response to the investigation.

“In order to reassure customers with concerns about the safety of their vehicles, we are voluntarily extending the recall.”

“We are therefore announcing today that we will take the proactive step of expanding the existing UK recall to cover all vehicles potentially affected by the power supply issue.”

The car manufacturer has recalled up to 500,000 cars in the US just in 2013, as well as in Australia, South Africa and Canada.
