2017 Mercedes-Benz C-Class seatbelts problems

It's a documented issue but not catastrophic. 23 complaints have been filed. Repairs average $500 and most owners catch it before it causes a breakdown.

Across the 13 complaints that reported odometer mileage, most seatbelts failures cluster between 20,000 and 50,000 miles, with the median around 22,000. A quarter of owners report trouble before 20,000; a quarter make it past 50,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $500 for seatbelts repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.

No active recalls currently cover seatbelts issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
