I had the exact same issue with my 2023 Caracal SP. I think it had something to do with getting wet. I live in AZ, and we don’t get much rain, but I sprayed down my boat a day earlier and noticed the lights didn’t light up, but the buttons still worked. Then, the next day, the lights started to work again. I think it completely dried out and started working.
Never a problem since.
Note that I have not sprayed the pad again, and it hasn’t been in heavy rain since then.
