Within that volume, owners reported 1 crash, 0 fires, 1 injury, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.

Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 4 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.

NHTSA currently has 15 investigation files overlapping the 2014 C350. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

I was driving my vehicle when the transmission started shifting erratically. The shifts were not smooth but hard and the car was shuddering. Yes the vehicle is available for inspection. My safety and the safety of others were at risk due to the erratic behavior of the vehicle and how it affected my ability to focus on driving safely. Yes my vehicle has been inspected by the manufacturer and the problem has been reproduced by my local Mercedes Benz dealer. There were no warning lamps or messages prior to the failure. After a few weeks of driving I saw a “low coolant” warning appear, this turned out to indicate that the radiator had leaked coolant into the transmission which damaged the internal transmission components and torque converter.
