Had a Yellow Warning Light Come On and Go Off a few times on the way Home from Work Last Night.

As a precaution, get out the OBD reader and check for any codes. If none, carry on!

Well, you're not going to be worrying about reduced visibility with a melted piston.

Just the people behind me.

When you go to On - every set light should go on to prove light works.
So this must be something else.

Or, perhaps there isn't an On mode with push-button start.
Only Acc mode with no brake press, and Start mode with brake press.
Not sure which is used for the light check. But if all the others lit up - you got it.

There's Engineering mode too, which shows all the lights, perhaps more than the set lights.

A bunch of lights lite up on the right like the check engine light and a bunch of other lights. But where the Yellow Light popped up Saturday Night nothing showed up in that spot.

Does that work on the 2025s since they are a 100% digital display?

If none of the symbols shown in the symbol glossary in the front part of the 2025 manual ring a bell, there might not be much choice other than to see if it ever comes back again.

I looked up those Symbols in the 2025 Manual and don't recall any of them looking like the Symbol that popped up. And since Saturday when it came on and went off 2-3 times I haven't seen it again and drove it Sunday,Monday, Tuesday and Today.

I don't have one of those I guess if it comes on again I can go to Auto Zone and have them check it.

Could you describe the mystery symbol that you saw? What did it look like?

Yup! Most of those parts stores have one and will pull the codes, if any, usually for no charge. Good luck!

I have a 2024, so I guess the display is different, but on a vehicle with a conventional instrument panel and an ignition key, when you first turn the key (prior to where it actually triggers the starter), ALL the indicator lights light up as a status indicator. If your 2025 display does something similar, that's the time to look for the mystery light.

It was on and off quick but it was yellow like I said before and IIRC it might have looked like a Vehicle kind of going across a hill side ways.

I have the push button start and the tachometer only shows up when you start the vehicle.And the Yellow Light was above the Tachometer. And like i said above when you push the start button without starting it a bunch of lights show up on the right side but not on the left where i seen the yellow light pop up.

Then I guess don't worry about it until it stays on.

That's what I'm thinking.

 

[Darryl]

That's what I'm thinking.

I agree. If it's a real problem, it will come on again before long. If it was an electrical glitch and never comes on again, that's even better

 

[BLUEOVALRACER]

The light came on and stayed on tonight for awhile then went out. I don't have a cell phone to take a picture of it. It's Yellow with what looks like a Vehicle at the Top with 2 yellow lines in an X shape under the Vehicle.

Starting on page 19 of this document is nearly every symbol that could conceivably show up on your dashboard.

Edit: You said you had already looked here. Do you still feel like the thing you're seeing isn't in the manual?
