What are the Most Common Problems with the Mercedes W210?

Despite its rock-solid build quality and durability, the Mercedes W210 suffers from a few potent problems over the years, particularly with mechanical and electrical parts. Some common problems include automatic transmission faults, steering wheel issues, intercooler problems, fragile suspension, and electronic issues.

4- Fragile Suspension

The wishbone in the suspension system of a W210 is known to be fragile and prone to separation. Owners have reported broken wishbone on their cars, which is reportedly a very expensive fix, that occurs usually after 200,000 miles.
