The convertible hard top hydraulic system start to leak oil to driver and passenger seat. The hard top does not move and difficult to close. I have received notification from several owners that it is a current problem of all vehicles of models. This is an unsafely problem, since the hard top, rear glass and trunk has problem to be locked completely. Apparently the Mercedes Benz manufacturer know that the hydraulic cylinders seals fail, once the mineral oil lose its property. This mean that hydraulic system get not protected after such oil is inappropriate to protect the seal, resulting on leaking and car finish without protection, . if it happen when it is snowing or raining or far away, it will become in a potential safety harmful problem for the drivers and passengers. I requested a service to Mercedes Benz and the answer vwas the repair will be almost $ $5000 merceds Benz should repair all the hydraulic system for hard top under a recall.
