App showing oil change needed, but oil level seems fine battery acting up too?

[compactluxurypro]

I own a 2019 Corsair, and recently the Lincoln app is telling me I need an oil change, even though the car says my oil level is at 70%.

Plus, I'm getting weird battery issues. Sometimes the remote won't lock or unlock the doors, and the start-stop thing quits working out of nowhere. I tested the battery not long ago, and it looked fine. These issues started after a long, cold trip.

Has anyone else had the app send fake oil alerts or odd battery problems that might be related? Could this be a sensor issue, or is the car's battery messing things up?

Any thoughts would be appreciated

I'm thinking the app's oil change alert might be time-based rather than solely relying on the oil life monitor?
That can happen if it's been a while since the last service.
As for your battery and remote issues, what you mentioned are common signs of a weak charge or a battery on its way out.
I'd lean towards the battery being the root cause of the remote and start-stop problems.
