I have a 2014 Enclave Premium. Recently the dashboard started flickering, the blinkers only work sometimes, and the car won’t start at times. I’ve had to turn the key over 4-5 times to get it to start (the car isn’t turning over at this point, it just acts as if the battery is completely dead). Then it will eventually start. Also, my driver crash response stopped working and both of the orange “crash detection” lights are staying on. Any insight would be appreciated.
