The 2015 Mercedes-Benz C350 has 4 recalls, the most serious involving the front airbags: the passenger-side inflator can explode and send metal fragments into the cabin, and the driver airbag can deploy without warning.
The passenger inflator issue is the Takata airbag defect, where the inflator ruptures with far more force than intended, throwing sharp metal shards toward whoever is sitting in that seat. Separately, a prior repair attempt on some of these vehicles may have introduced the wrong passenger airbag module entirely, meaning in a crash the bag may not deploy correctly or at all. The driver airbag concern covers an inadvertent deployment, where the bag fires without a collision, which can startle the driver, obstruct vision, and cause a crash. There is also a software fault in the emergency call system, where an incorrect date and time can cause the system to transmit the wrong vehicle location to emergency responders, potentially delaying help from reaching the right place after a crash.
