Mercedes-Benz is recalling about 48,000 SUVs in the United States to fix a sensor problem that could stop the front passenger air bag from inflating in a crash.

According to ABC 6, the recall covers Mercedes-Benz's GL, GLE, and GLS models from the 2016 and 2017 model years. Mercedes stated in documents posted by U.S. safety regulators that "a sensor in the front passenger seat may be calibrated incorrectly. It can classify passengers as child seats and deactivate the air bag."

From the documents, it was unclear if the problem had caused any injuries.

"Mercedes will notify owners and dealers [of the problem and] will update the sensor software for free. The recall is expected to start this month."
