The RX8 has one of the most complicated steering systems in the industry.
First, if you just consider the problems that can occur with the power steering mechanical and basic sensrs, there are failure possibilities such as;
Internal pump or Rack pressure failure due to by-pss of fluid around an internal leaking seal or o-ring.
Pressure sensor for speed sensitive steering.
The pump could have failed to provide adequate pressure.
Then there are the considerations of the electronic steering sytem controls that get so involved, I will give you some of the higher level functions just to give you an idea;
If you have Tire Pressure Sensor Monitors, they must be reset after any re-balance and rotation of the tires.
There could be a failure of sensors or controls with the active steering components such as the steering angle sensor and the steering yaw sensor. The steering angle sensor measures the angle of the wheels and the ywat snesor meansures the angle of the car compared to the angle of the wheels to determine if the car is over-steering or under-steering. Any modification to the suspension or suspension work should be performaed by a Mazda dealer as this will affect the system.
Then it gets more complicated. The best thing to do is to have the Diagnostic Trouble codes pulled. Normally, I would refer you to an Advance Auto or Auto Zone as they pull codes for free. And you should try them first. However the steering system is so complicated that a special code puller is required and the standar code puller may only get a failure in the sytem code when a dealership will get a much more accurate diagnosis.
Not all models of the RX8 may have all the elctronics that are offered and that makes diagnosis very tough.
If you can't find the problem easily from a standard code reader or you have the full elctronic active steering and suspension, Tire Pressure Measurement System, etc. I would reccomend going to a Mazda dealership to have it serviced.
It is an issue of what you have in options, what a standard code reader will pull as the trouble code and what the actual problem is.
Let me know if you have any further questions.
