Im not so sure if its 100% or 75 or 85

That is 75%. If it was 100%, the box would be totally blue. You should expect the icon to show 50% or 75%. If it shows any other indication, that is a clue the battery is bad.

 

Hi Zach,

The behavior of your traction battery SOC gauge is normal if it switches between 50% and 75%. The Classic gauge only has four segments, thus it can only show the following possible readings: 0%, 25%, 50%, 75%, and 100%. It is not possible for that gauge to show finer readings than that.

Compare to the 2G gauge that has eight bars, so it can show nine different SOC states.

Also, please note that when the gauge shows 0%, the battery is at ~40% actual SOC. When the gauge shows 100%, the battery actually is ~80% SOC. Thus, the gauge is showing you an expanded view of SOC from 40% to 80%.

 

We're a Prius family. When my daughter leaves for work mornings she backs her 2003 Classic out of the garage and while doing so the steering wheel shaft begins vibrating (shuddering) when turning either left or right. This does not happen while moving in a straight reverse line. Nor does it happen at anytime after a brief warmup. Driving forward at any speed is smooth and troublefree. A conversation with the service manager at our Toyota dealer developed the suggestion that the rack and pinion assembly may need repairs. I suspect it may be something involving hydraulic fluid somewhere in the steering system because it corrects itself after warmup. Has anyone had this problem? Thanks for helpiing.

 

The Prius power steering system is electric, not hydraulic - so you don't have to worry about fluid being an issue. The electric steering gear is a weak point and the steering wheel vibration is a symptom that the torque sensors are starting to fail.

Its interesting that this happens only when the car is in reverse...

 

Sorry. I posted my new thread in this group. Forgot how to do this in my old age. Forgive me.
