MPG Avg. & Road Trips Resetting

[CSULA21]

Anyone else have issues with the MPG. Avg. calculator & the Road Trip mileage trackers resetting on their own? My car is doing this about once a month. I got the car in March.

There are two screens. One resets after 4 hours of inactivity. The other resets only when you manually reset. Are you saying both are?

That's right. The last '16 Genesis that I had never did this. I had to manually reset the trip meters and the only time the MPG Avg. tracker would reset was after refueling (or unless I manually reset them). These are resetting on their own.

Mine does it 2-3 times a year. You will notice the dash lights reset to full brightness also.

Sounds like a DC power issue. Maybe one of your battery clamps is loose, or the fuse on the positive one?

Mine has done this several times since I got the car in March. And, the dash lights do not revert back to full brightness, as I have them one setting below full brightness & have not had to dim them again.

Wouldn't that reset everything? Why just those 3 things?

I thought about terminals the first few times it happened but everything is tight & the battery load tests at over a thousand amps.
For me I think it is a software glitch either during shut down or start up that causes a soft reset of the instrument cluster. Since it only happens 2 or 3 times a year it is a minor inconvenience only.
I know when it happens as I normally have the center display on MPH. When I start the car and the display is on trip 1, miles set to 0, I knew it reset.

It happened to me periodically for a few months ... and it was very annoying because I meticulously record each fillup and mileage into a spreadsheet. After I had a new battery installed, the problem hasn't happened again.
