What stands out
Steering accounts for 29% of all owner complaints filed against this vehicle, across 4 categories tracked.
No new NHTSA steering complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
The failure pattern owners describe
Power steering is the main complaint here. Owners describe the steering wheel getting rock-hard and difficult to turn, especially during low-speed city driving and parking. Some say it happens sporadically after a few minutes behind the wheel; others report the wheel seizing when turning corners. A few had to use both hands and extreme force just to maneuver the car, with one driver developing shoulder pain. Failures started showing up around 54,000 to 80,000 miles.
The root cause, according to repair shops, is hydraulic power steering failure—specifically a defective power steering oil pressure driving pin. One dealership diagnosed the need for a complete steering rack replacement at $4,000. Another shop found the steering pump itself bad. Power steering fluid leaks appeared in several cases; one owner was told the leak was non-repairable and he'd need the system flushed every 3,000 miles.
Some owners heard groaning from the steering system. One mentioned his air suspension also failed at the same time, causing the car to sag. Mercedes issued recall campaign 08V682000 for steering on certain 2008 R-Class models, but multiple owners reported their VINs weren't included in the recall batch despite identical symptoms. The disconnect between recall scope and actual failures appears to be a frustration point for affected owners.
