Total Complaints
By System
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.
The 2010 Mercedes-Benz R350 has 3 recalls, the most serious being a driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, potentially striking the driver or other occupants.
The remaining two recalls both concern the same brake booster issue: moisture can collect inside the brake booster housing and cause corrosion that weakens or destroys its ability to assist braking. When the booster fails, the brake pedal becomes significantly harder to press and stopping distances increase, raising the risk of a crash. Prior repair attempts did not fully resolve the issue, which is why this defect appears across more than one recall campaign for this vehicle.
