This page covers 3 recalls and 18 owner complaints for the 2011 Mercedes-Benz R350.
The dominant pattern in 2011 Mercedes-Benz R350 complaints centers on airbags, which account for the majority of the 18 filed reports. Most of those complaints don't describe an airbag failure in the traditional sense, owners report showing up at dealerships for a scheduled airbag repair only to be turned away because parts weren't available, sometimes repeatedly. A smaller cluster of brake complaints includes one owner who describes ABS engaging unexpectedly at highway speed, accompanied by the front end dipping and grinding noises during braking stops. That same owner reports having wheel speed sensors replaced eight times over several years. Engine complaints are limited to a single report with no detailed symptom description. The complaint picture here is less about acute mechanical failures and more about owners unable to complete airbag-related service work due to persistent parts availability issues.

By System
The 2011 Mercedes-Benz R350 has 3 recalls, the most serious being a driver's frontal airbag inflator that can rupture in a crash and send metal fragments into the cabin, risking serious injury to the driver or passengers.
The remaining two recalls both describe the same brake booster defect and should be treated as one issue. Moisture can build up inside the brake booster housing and cause corrosion, which reduces the unit's ability to assist with braking. In a situation where firm, fast braking is needed, the pedal may feel harder to press and stopping distances can increase, or braking power can fail entirely.
