I briefly looked through this forum and could not find a similar issue so I apologize if this issue has been answered before.
so whenever I park my car and remove my key the power to my car completely stops (i.e locks, windows, clock all stops working) the only way I can get power to the car is by disconnecting and reconnecting the battery. I had the battery tested and it is still good, the battery is only a few months old.
I would appreciate any help at all, I’ve googled this issue and couldn’t find any info.

My car has had a rearview camera and a pioneer radio installed, however these two items were installed about 3 years ago and this issue just started 2 weeks ago so I don’t know if they would be the cause.

**update** I think I got this resolved. I ended up cleaning the battery terminals really well and replaced the battery cables. No issues so far.
