## NHTSA's summary

Mercedes\-Benz AG \(MBAG\), the manufacturer of Mercedes\-Benz and Freightliner vans, has determined that the software of the MBUX multimedia system might not meet specifications. Under very specific conditions, the MBUX multimedia system might not start and the display might remain black, or could reboot unintentionally after 50 seconds of initial startup. Accordingly, the rearview camera image might not be displayed or the display might be interrupted which could increase a risk of a crash or injury.
