General Random warning on dashboard

[Sarahp]

In the past month I have had various warning on my dashboard “stop start unavailable “ “hill holder unavailable “ “transmission see handbook”
The car is performing fine , the battery is in good condition and the warning come up every 3-5 days then go away for a few days .

I have had a new battery fitted 2 months ago and have just had it tested and it is performing good .

Is this a electrical issue ?

Could be a bad earth. As you have hill hold it must be fairly new car so it’s unlikely to be corroded though.

Is the car a automatic?

Are newer cars immune to the tailgate wiring problem?, knowing Fiat prob not just won't happen for a while if it's that new! But......
