Why is my car not recognizing my cell phone anymore?

UN-PAIR phone to car and car to phone - start over.

Hello, I'm concerned that you have a Bluetooth issue as well as a charging issue. For Bluetooth: Don't forget to delete your car from your phone AND your car from your phone before trying to re-pair. You need an all new relationship on both sides. The software relationship between the vehicle and the mobile phone gets corrupted typically when the operating system is updated - iOS or Android. For the lack of charging, check your fuses for the circuit, as one more more may be blown.
