The affected models, all built between 2015 and 2017, form part of a larger recall which affects over a million cars worldwide.
In documents filed to the US government, it was revealed that repeated attempts to start a car which won't turn over could cause a current limiter in the starter motor to overheat and melt other parts. According to the documents, Mercedes began investigating the problem last June following reports of 'thermally damaged' current limiters.
A total of 51 fires have been reported worldwide, with 30 in the United States alone. Mercedes says there have been no reports of injury.
Mercedes owners will be notified later this month if their car is affected, and again when replacement parts are available, which is anticipated to be July. Dealers will take about an hour to rectify the issue, and will install another fuse to prevent fires. All work will be free of charge.
