Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
Airbag complaints dominate what owners of the 2010 Mercedes-Benz C350 report, accounting for the majority of the 18 complaints on file. Most of these describe airbags failing to deploy during collisions, with owners reporting that front airbags did not activate even in impacts they expected would trigger them. A secondary pattern involves interior door handles, where multiple owners describe the cable attachment mechanism breaking during normal use, leaving occupants unable to open the door from inside. Steering and engine complaints each appear only in isolated reports and don't form a clear pattern. The door handle failure comes up consistently enough that it's worth noting: owners describe the plastic eyelet on the cable snapping off, rendering the handle non-functional without any warning.

By System
The 2010 Mercedes-Benz C350 has 4 recalls, the most serious being a defect in both the driver and passenger frontal airbag inflators that can rupture during deployment, sending metal fragments into the cabin and causing serious injury or death.
The airbag inflator issue affects both seating positions: the driver-side inflator and the passenger-side inflator each carry the same risk of an explosive rupture that launches metal shards toward the driver, front passenger, or other occupants. Prior repair attempts did not fully resolve the issue, and multiple rounds of replacement have been conducted over the years to address the same underlying inflator problem. There is also a lighting concern: a weak electrical ground connection in the tail light circuit can cause the tail lights to dim significantly or go dark entirely, making it harder for drivers behind the vehicle to see braking and turning signals in time to react.
