Check EV system error

Wed May 22, 2019 4:38 am

We are getting a “check EV system” error after periods of highway driving that exceed 15minutes. The car begins to slow and enters turtle mode... the second time we had to stop as the car would not ascend a hill.

Trouble is, if you turn the car off for 2-3 min the error disappears and the car returns to a normal state of charge eg: 70%

So the battery is not depleted, but the EV system doesn’t know this.

The dealership has seen the car and acknowledged the error but can not in-act a repair as the error is not active! So now we get to mess about with not knowing if we will arrive at our destination or not until the damn error sticks.

Anyone else experience this?

Sounds like a repeatable event; true? Maybe connected with some heat buildup ? Any temp. data that might correlate?

Definitely repeatable. It’s spring here so the temperature is around 15-20C

It’s going to a different dealership that wants to keep it and try to recreate the error... yay, some yahoo racing around in my car for a day...

You would think this kind of event would leave a trace for their ODB scanner to find. Strange.

Oh the error is in memory... trouble is they will not do any warranty service unless the error is active... ie; light is still on.

When we restart the car the error is gone.

Made it to the dealer with the error still active.
They found that the coolant was low and topped it off. We’ll see if it fixes it.... I am skeptical though as it was just below the min level on the reservoir... they ordered a replacement pump in case the problem reappears.

Check EV system error seems to be a generic fault warning that may have many different causes.

Some previous threads with this include.

It seems possible that low coolant could be one of the things that cause this error.

This happened to my wife today as we were driving up a steep canyon. It went into turtle mode and came to a complete stop. We were able to back up downhill to a spot that had a shoulder and was level.
When I turned it back on in an attempt to back further to a safer spot the indicator light was gone.
We drove home fine.
the coolant level is at the min line.
we are adding coolant.
downloading torque pro to get codes. my son is trying to figure out how to do it. I have an iPhone so he is using his android.

I could not get the Torque pro app to work on my son's phone with the csv files so he deleted it.
good news is the other OBD adaptor I use for my nissan Leaf worked to get the codes on the Soul.
they are as follows:
POA 93- "power limited" no suprise there we were in turtle mode.
POC73- "Electric water pump" this gives ma hope that adding the coolant might fix it.

I did not clear the codes in case it acts up again. we are taking a 100 mile trip tomorrow and plan or first QC. I am slightly nervous, but we are going forward. We are at least driving in the direction of a Kia dealer if it happens again we will take it in and leave it.

We made the 130 mile Round trip with a DCQC at 20%
came home with 40% and L2 charged to 100% and did another short trip out and back ending at 30%
no problems and we did highway speeds elevation gain and full A/C with no return of the error codes.
