12/24/2013

DETROIT — U.S. safety regulators have expanded an investigation into rear light failures in Mercedes-Benz C-Class luxury vehicles.

The probe now covers nearly 253,000 cars from the 2008 through 2011 model years.

The National Highway Traffic Safety Administration says the stop, tail, and turn signal lights can fail because of a melted electrical connector.
