Fuel level depletes when parked; increases while driving.

Hi all,
I’m having an issue with the fuel gauge on my 2014 Cruze diesel. About 1 out of every 4 times I park the car and walk away from it (could be 15 minutes or all night), the fuel gauge will read about 1-2 marks below the true level; then, it will gradually increase while I drive (increases about 1 mark for every 20 minutes spent driving), until reaching the accurate level.

Has anybody experienced this? If so, what should I be looking at? Makes me wonder if the fuel level sensor is float-based or if it has some other pressure-based sensor.

Any help is greatly appreciated!!! Thanks

Have you noticed, has it ever happened when tank is full?
When fuel level sensors start to fail, then sometimes the first symptoms are inaccuracies in most used area which is between empty and half.

Update: it does happen when the tank is full and I am parking on flat, level ground. I’ve decided to live with it for now, annoying but not the end of the world. If the sensor / sending unit / etc. goes out completely, I’ll look to replace. Thanks for the replies.
