The 2016 Mercedes-Benz S600 has 4 recalls, the most serious involving the electric power steering system, which can lose its assist force suddenly and make the steering wheel significantly harder to turn, raising the risk of a crash.
The front roof panel, the section of roof sitting between the windshield and the panoramic sunroof, is the subject of two related recalls. In both cases, the adhesive bonding that holds that panel to the body can fail, allowing the panel to detach while driving and become a hazard for other vehicles on the road. One of these recalls is specifically tied to vehicles where a prior repair may not have restored the bond correctly, while the other covers deteriorating factory or service adhesive more broadly. The underlying danger is the same either way: a piece of the roof can come free at speed.
The fourth recall involves the onboard emergency call system. A software fault can cause the system's internal clock to show the wrong date and time, which in turn can cause it to calculate and transmit an inaccurate vehicle location when a crash triggers an emergency call. That means first responders could be directed to the wrong place, delaying their arrival when time matters most.
