Your car is telling you to contact the dealership, not a mechanic or to get it checked. That's very intrusive, anti-consumer and anti-repair. It's your car and they shouldn't be putting shit like this in it. Most they should say is "please get it checked" or something like that.
To be fair, my car has one specific circuit board that can only be fixed by a dealership mechanic. Found out about that one after it malfunctioned on the highway, my car turned off, and I couldn't use the breaks while coasting at 65 mph. I called half a dozen mechanics before one told me that it was a dealership issue because it required special equipment to code the circuit board. Wish my car told me that so I wouldn't have wasted all that time.
This should enrage you to the moon and back. This is THE anti-repair/anti-consumer that I'm talking about. I had the same issue the other day on my car rear brakes. A friend of mine is a mechanic and he has this Bluetooth device that he has to use to unlock MY FUCKING BRAKES. And he has to pay $1200 a year subscription fee to update/unlock that software from Hyundai, otherwise it stops working. A car that is completely paid off is locked by the maker and I can't just change the brake pads and rotor on it. This made me extremely mad. I didn't know about it and now I'll make sure my next car doesn't have this shit on it.
