Electrical system (complete) started acting "wonky"... First minor issues such as the stereo system was lagging (turn the volume knob, stereo won't change volume for example), then I can't turn off the radio at all. Max volume... and it won't turn off! Had to turn the car off completely and disconnect the battery for a few mins before reconnecting and restarting.

Then other issues like my blinkers would all start flashing left and right and on and off... Beeping dinging (the same as when your door is open)... Madness! Then all sorts of notifications come on like airbag needs service or check engine light. Plugged in my OBD2 reader and no issues! What's going on?!

The worst was when my car wouldn't lock or unlock... Had to use the manual key. Then the battery in the keyfob allegedly had a "dead battery" according to my vehicle's dashboard. So I replaced that with a brand new battery and no fix! Had to put the key in the glovebox (next to the key sensor) to start the vehicle.

All of these issues were intermittent... They wouldn't all happen at once (or they would)... Typically they were miscellaneous and intermittent at different times.

Took it to the dealer to get it looked at on 1 April. They said my battery was fine (it was reading 12V) and there was nothing they could do. I replaced he battery anyway and it seemed to fix the problem immediately.

Until a couple of months later when I start getting car won't start issues due to dead battery... But that's for another complaint!

Terrible!
