2010 Mercedes-Benz R350

For the 2010 Mercedes-Benz R350, airbag-related complaints make up the largest share of owner reports, with most describing difficulty getting replacement parts or service appointments rather than an in-vehicle failure event. Brake complaints are the next clearest pattern, with multiple owners reporting the brake pedal becoming stiff or hard to depress, sometimes accompanied by a warning light and abnormal sounds at low speeds. One owner had the brake booster diagnosed as faulty. Engine complaints round out the picture but are too few to describe a specific pattern. The brake pedal stiffness issue appears across several reports and seems to surface at various mileage points, with at least one case occurring around 130,000 miles.

Complaints are owner-reported and reflect individual experiences, not confirmed defects. They are distinct from recalls. Data sourced from the national vehicle safety complaint database.
