Tiles: each year’s median failure mileage. † Median likely runs low (complaints filed after 2020). Latest: the 2015; earliest: the 2017, and the 2015 is 2 years older (part of the gap is age). 4 of these years carry fewer than 30 reports with an odometer reading and show no median at all, rather than one computed from a handful.

Documented problems

What each one is ↓

Owners filed 1,178 complaints with NHTSA about the 2015–2021 Mercedes-Benz C-Class; the engine leads with 32% of them, and half of the 364 that record an odometer reading came by 40,000 miles — complaints, not a failure rate.

No single peak: the middle half runs 12,000 to 63,000 miles.

How many miles does a 2015–2021 Mercedes-Benz C-Class last?

On the 2015–2021 Mercedes-Benz C-Class, half of the 364 complaints that record an odometer reading were filed by 40,000 miles and 90% by 90,000 miles (why that is not a lifespan).

3 reports came in past 150,000 miles — each one proof that a C-Class reached that mileage, not that it failed there.

Known problems with the 2015–2021 C-Class

Engine 2015–2016

M274 2.0L turbo wrist pin and piston issues on early C300 builds, presenting as knocking or ticking under load.

Electrical 2015–2021

Rapid battery discharge and parasitic drain, particularly on vehicles left standing; a leading no-start cause for the generation. Keyless-Go module faults typically appear around 40,000-60,000 km.

Infotainment 2015–2018

COMAND infotainment freezes, reboots and display faults, concentrated in pre-facelift cars and often appearing within the first 30,000 km.

Body 2015–2021

Door handle sensor and LED failures (typically 60,000-80,000 km), sagging sunroof shades, and interior trim noise.

Suspension 2015–2021

Airmatic air suspension failures on so-equipped cars — compressor and air strut leaks causing ride height loss.

That makes the 2015 stand out at roughly 2.6 times a typical year (what a yearly count can and cannot say).
