It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump.

    Power steering has failed. Fluid is leaking profusely. The Chico Mercedes Dealer says that the problems are NOT covered by the recall notices. I plan to take my vehicle to a private mechanic to see what can be done to resolve the fluid leakage & get the vehicle running in a safe manner. I filed a complaint with the NHTSA.

    Power steering rack assembly leaked after pump replacement caused by wrong fluid. New pump increased pressure in system and seals on the rack started to leak. Ordered rebuilt rack assembly which was fitted. Steering problems resolved, including lack of precise response to steering commands. Rebuilt rack solved the problem, expect to pay for at least eight hours shop work. Core refund is around $150. With a rebuilt rack cost around $400.

    I bought this pile of junk at 80,000 miles. Noticed a noisy steering problem right away. Had the fluid flushed and replaced and it helped, but now getting louder and louder and more annoying. Buying this was a huge mistake as this is the LEAST of the problems.

    Power steering hose popped out three times! Fluid leaked out...completely. Ugh! Cost to repair, part: $170.00, labor $150.00. Hope this doesn't happen again.

    Rack has completely failed, seals shot. All failed just around the time the hose clamp failure happened. I think the hose clamp failure is directly tied to the rack failure.
