Any Other Prius Owners Have This Problem?

I have a 2012 Prius III, and my slip indicator light comes on randomly; while I'm stopped, when I accelerate etc and it will stay on, and then shut off randomly. I had the dealership look at it, but it picked just before I got there to go off so they couldn't get the "error code" from it. It recently happened again, only this time it was on from the time I started the car and has been on for the past 4 hours, I've turned the car off and on a few times, but it remains. The dealership was able to get the code, but reported back to me that it's one they have never seen before. This is what I found online:

"If the light stays on, it could indicate a malfunction in:

• The VSC system; or
• The TRAC system

Failing to investigate the cause of the warning may lead to the system operating abnormally and possibly cause an accident. Have the vehicle inspected by your Toyota dealer immediately."

Not sure why they just threw their hands up last time and shrugged their shoulders with an "I don't know" especially if it can cause an accident, but at least this time they got the code and gave me a loaner. I've looked for recalls, but haven't found anything out.

Has anyone else experienced this? What was the resolution? Thanks!

 

The dealership has gotten the error code and also has seen the slip indicator light on; they've kept the Prius for now because they haven't a clue what the error code means as they have never seen this specific error code before. It's one of the largest Toyota dealerships in my area, so I am just surprised to find that they couldn't diagnose the problem based on the code. It's under warranty and all that jazz, I just wanted to see if anyone else has experienced the same issue.

 

I only had something to drive because when I bought the Prius I bought and paid for "rental" coverage. I had to force my hand to get the guy to give me one because he said "we only give out a loaner once we know what the problem in." Not knowing what the code means, to me, says you know what the problem is, you're just not educated enough to know what the code means.

They tried to do a band-aid fix; add a wire into the harness to correct the short that was causing the light to stay on. It took less than 2 short drives for the light to come back on. My guess is that the extended warranty that I bought says they are allowed to fix it however they'd like - chewed up stick of bubble gum and DONE!

Turns out it was a switch or sensor, the guy wasn't very clear. They took one off a Prius they had on the lot. Not sure what the cost was as I didn't have to pay for it.
