2021 Mazda3 Fuel Gauge Issues...Anyone else?

[Jlyle2795]

So I am from Australia with a 2021 Mazda 3 2l and my fuel gauge is a concern. I’m going to be getting it checked by Mazda but want to see if anyone else has had the same or similar issue. So i will fill my tank and when it clicks off that’s it I don’t add any more I mainly fill at the same station and pump with some exceptions when I can’t use the same pump or if I’m on holidays but this never changes and my concern. What happens is I can drive 100km’s and it the guage will drop however I am finding I can drive up to 200 kms ( in small trips around town sometimes on a long drive) and the guage will move down but it will then move back to full. Being curious about the unusual behaviour I have filled up when it’s used 1/8th to 1/4 of the tank (gauge showing 7/8 or 3/4 full) and can find that I put in any where from 16l to 30l of fuel. At other times I can have half a tank and fill up and put in 25- 28l. I don’t think this is normal and it is gradually getting worse. Let me know if anyone else has had a similar issue
