| Description of the problem | Nhtsa 08v682000 defect in power steering oil pressure driving pin. The nhtsa should reevaluate accepting mercedes benz underestimating of the amount of vehicles that were effected by this recall. There are still vehicles that are loosing power steering pressure due to the driving pin that is used to control power steering oil pressure being defective and this is a major safety issue that could result in deaths and accidents. The pin breaks during normal vehicle turning so the steering assist will no longer operate effectively it also causes other damage to the vehicle as a result of the hard steering defect as a result of the pin breaking. When driving cold the vehicle has power steering available, when warm vehicle looses power steering, fluid is circulating in power steering pump and pressure checks fine. As a result due to hard steering leaks develop due to power steering pressures variances in the steering system over time a fire and other potential problems can arise. There is also a popping sound felt in the steering wheel not due to tie rods. |
