BMW AG is recalling more than 19,000 i3 REx plug-in hybrids in the U.S. because they could develop a fuel vapor leak that would increase the risk of a fire.
Cars from the 2014 to 2017 model years produced between March 2014 and December 2016 are affected by the recall.
BMW says a fuel tank vent line may rub against the sleeve of a battery cable. Over time, that can cause a hole and vapor can leak out.
The company says it knows of no fires or accidents related to the problem, which was discovered by a dealer.
BMW will notify owners and replace the fuel vent line for free. The recall is expected to begin in April.
