I have japanese alto 660cc 2015 model .....electronic car steering is slight stiffer no light signal is on the dashboard and no fault signal on computer ..my question is how to solve this steering stiffness problem otherwise car is running smooth no change in line no vibration while driving no unusual sound while turning....is this okay or what I do???
- Well first check to see if you got a problem with ball joints or struts which would bind it and make it stiff. But if not that generally it means the motor starting to wear out on the power steering
I have recently installed new kyb struts but ball joints are in good condition...mechanic tight the bushes of steering rack or may be repaired it now what would I do
you should have included complete information in your question. Scotty doesn't doesn't re-answer.

electronic car steering
Is it 'real' electronic power steering, where the steering is actually driven by an electric motor?
I'm unsure how the EPS is implemented in a 600cc Alto.
The way it was implemented in the European Alto: (“Real EPS” aka motor driven power steering)
In that case you want to focus on the battery and charging system - test them with a special battery/alternator tester.
'real' electric power steering motor often require 35 amps or more at peak load!
The round thing at the bottom is a 370W (30.8 amp) electric motor that turns and provides assist based on the requests made by the box at the top - the EPS ECU.
When there's not enough battery power / generator performance - the steering tends to feel heavy,
BUT it's not uncommon for that symptom to be caused by EPS ECU failures and other component issues.
Or is it a system where the electric portion drives a pump that powers a hydraulic system.
This is more than often related to fluid level / condition on these, sometimes the pump.
EPS ECU failures are also not uncommon on this design.
The electronic part is at the bottom - it's the pump that pumps the fluid sitting on top in the reservoir.
In both cases a common fault is with the EPS ECU it self, or if the steering is 'digital' (like on Hondas) it can also be the sensor / its calibration.
AND, SOMETIMES IT IS THE WIRING! DOES THE STEERING FEEL THE SAME WITH THE IGNITION ON AND THE ENGINE OFF COMPARED GO THE ENGINE BEING ON?
Generally, you want to find a mechanic that knows how these systems work.
It can be expensive, it can be cheap - it depends on how well you can pinpoint the exact source of the failure.
