Credov's researched list of the 3 faults the Mercedes-Benz C-Class W205 is known for (2015–2019), 1 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Check that no airbag warning message or red airbag light stays on after start-up, and ask for the recall record.
Why it matters: The notice describes the driver's airbag deploying without a collision, which could injure and distract the driver; a live airbag warning also needs resolving before the car is retailed.
What to look for: Feel the panel between the windscreen and sunroof for movement or a lifting edge, and ask for the recall record.
Why it matters: A detaching roof panel at motorway speed is a hazard to following traffic and a wind-noise complaint on the retail side.
What to look for: Ask for both turbo oil line recall records, look for fresh oil at the turbo pipes, and smell for burning oil.
Why it matters: Oil on a hot turbo is a fire risk and an oil-starved turbo is an expensive one.
