I have a 2019 Mazda CX-5 Sport AWD. About a week ago, on a very cold day (-5F) I noticed that the TCS/DSC warning was on. It's the yellow light of a car with squiggly lines underneath it. I don't know exactly when it turned on but it didn't turn off during my drive. Since that day, it hasn't been on again. I've bought the car new in 2019 and I've never noticed that warning before, even in cold winter weather in previous years.

Do I just be vigilant and watch to see if it comes on again? Do I bring it in and have them check a non-existent warning?

What do you think?

 

We have seen that a lot and even my 2019 Mazda does that occasionally. Next time if you just turb the engine off and restart it should go away. The cause for concern is if does not turn off on a normal drive longer then about 30 minutes. If that happens you need to have use of a Professional Scan tool and see what is going on.

WARNING: Cautionary advise
It is always in the best interest and SAFETY when any yellow indicator light having to do with the braking or stability control system is activated to reduce your normal driving speeds.
