Jul 8, 2026SuspensionBrakesFuel systemFire
Vehicle subframe corrosion (manufacturer extended warranty offered). Rear brake lines corroded/leaking. Vehicle leaks fuel; steel fuel line corroded. Vehicle has about 105k miles. Minor fire started when yard maintenance came in contact with fuel saturated ground where vehicle had been parked/moved out of the way just prior. With rear suspension subframe springs corroded, vehicle bottom can contact road surface while driving, scraping steel exhaust with fuel present. EXTREMELY dangerous. Local Sunbury Ohio Mercedes dealership inspected then offered subframe replacement. Stated it was leaking fuel and not hydraulic fluid we originally thought. Brake, suspension and fuel line corrosion repairs were quoted in excess of $4,000, which was a "great deal" according to them "because the subframe would already be removed and would make it much easier."

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
