Problem overview

Some Mercedes-Benz C240 owners report experiencing steering wheel movement issues due to a faulty lock mechanism, which can pose significant safety risks. These problems are often linked to a defective steering lock mechanism, leading to difficulties in steering control. Additionally, some owners have reported that a damaged steering rack can cause uneven steering and challenges in turning the wheel, further increasing safety hazards. If there are weak sounds from the steering lock release or unusual noises while turning the wheel, it is advisable to have the steering system inspected by a specialized Mercedes-Benz repair shop. Regular inspections can help identify signs of wear early, allowing for timely repairs to maintain smooth steering control. In certain situations, the steering wheel may become locked due to this faulty mechanism, and owners may need to try wiggling the key and steering wheel simultaneously to unlock it. It is essential to address any steering-related issues promptly and seek professional assistance from a qualified mechanic or dealership if persistent problems arise.
