Vios Problem

[GayanR]

Hi guys,Lately I'm exeprinecing a kind of a weird problem with my Toyota vios car.Car runs smooth normaly,but occationaly on some days car looses it's overall riding smoothness.Mentioned below are the symptoms I exepriance when this happens.(All happens at once)

Steering become somewhat stiff.

Car starts to shift hard and downshitt hard.(Not so hard but I feel the roughness,unlike when it's smooth),starts downshifting quickly and very frquently.

Brake looses some power,looses the smoothness,brake paddle starts traveling near to the floor.

car looses it's free traveling smoothness.(a/c on or off doesn't have any effect)

This remains till the next day,other day smooth like butter.

Other than that I don't experince any rough idling or engine miss.Fuel consumption is the same.Car Accelrates fine when power needed.I'm curious to know what's going on.tanx.

Your car seems to have multiple unrelated issues from your description.

The steering stiffness can be a result of the power steering belt slipping if you have hydraulic power steering

The brake pedal going down could be the result of leaky brake seals. This should be investigated immediately

When was the last time you changed ATF fluid?

Adding to what Don said, Check the Fluid of Steering and change it too. even in mine feels bit stiffness and it went away after changing fluid. (Used Dexron II Toyota ATF Fluid 1 Ltr can).

This is just my gut feeling but it sounds like you got an electrical fault. Hopefully a more experienced member would have an explanation.
