The recall, announced yesterday, affects about 109,000 cars in Britain, BMW said. It concerns 5 and 6-Series BMWs built between 2003 and 2010.
BMW said it was writing to car owners offering a free repair, which would take between 30 and 60 minutes in a BMW workshop.
“In some remote cases, the battery cable cover inside the boot of these vehicles may be incorrectly mounted,” it said.
“This can result in the electrical system malfunctioning, the vehicle failing to start and, in some cases, to charring or fire,” the company said, adding it was not aware of any accidents or injuries to people due to the problem.
Fewer than one per cent of the cars BMW has so far inspected for the issue have exhibited the problem and there have been no reports of fires.
