Eight complaints have been filed about the rear engine compartment in 2008 and 2009 ForTwo models. The NHSTA says that Mercedes-Benz, which builds Smarts, is unaware of any injuries related to this problem. Of the eight complaints, six occurred while the car was being driven. Drivers said that the check engine light came on and they noticed smoke and noises before stopping and discovering the fires. The two other drivers said that they noticed the problem when they were stopped. In all eight cases, the fires were “severe” and “rapidly engulfed” the entire vehicle. There are 42,875 2008 and 2009 ForTwos in the US which could be affected.
