What does the orange wrench symbol mean on my 2016 Ford Fiesta?

I was driving my car home from work and a wrench icon came on. The car drove regularly and I'm aware that I'm due for an oil change. I'm going to take it to the auto shop tomorrow but I'm reading online that the wrench means there's an issue involving a power train malfunction… What is that? Is it possible it's just warning me that I need an oil change?

It's the check engine light. It's a reminder that it's time for maintenance.

Why read about it online when the owners manual says what it means

A description of all the dashboard symbols and what to do when they illuminate can be found in the owners manual. A car that new should still have the owners manual in the glove box and a reasonably logical and intelligent person would have checked it first thing

I'll bet your owner's manual explains it.

Take the car to the dealer and have them read the codes.

If you want to read something, try reading the OWNER'S MANUAL that came with the car. It will explain what all the symbols and warnings on your instrument panel mean.

It probably needs something more than just an oil change, why not get a qualified mechanic to look at it.
The orange symbol means you have a problem. A red one means STOP you have a big problem.

The wrench near the 6 on your tachometer is the OIL CHANGE INDICATOR.

The Ford IOLM (Intelligent Oil-Life Monitor) system is a software based, algorithm-driven device that takes into account various operating conditions of the engine to determine when the oil needs changing. Certain driving habits affect the life of the oil. The oil change interval could be somewhere between 3000-10,000 miles, based on driving conditions.

There's a quick procedure to shut it off.
