INFINITI M37 loud power steering noise over engine on INFINITI M37

Some INFINITI M37 owners report experiencing loud power steering noises that are noticeable over the engine, which may indicate several underlying issues. These owners have identified potential causes such as air in the system, low power steering fluid levels, or restrictions in the fluid suction line, which can lead to whining or moaning sounds. Additionally, low fluid levels or a faulty power steering pump may produce whining or groaning noises when turning the steering wheel. Some owners also report a squealing noise during turns, potentially signaling a failure in the power steering unit or issues with the belt. A loud whine upon starting the vehicle that changes with steering movement may suggest a transient problem that lessens with driving. Furthermore, noises like whining, squealing, or groaning during turns could indicate low or contaminated fluid, a worn belt, or a failing pump. A grinding or rubbing sound while cornering might point to wear in the steering column bearing. It is recommended that owners experiencing these symptoms have their power steering system inspected by a qualified mechanic for proper diagnosis and resolution.
