“My car will be running fine but the lights on the AC panel wont work. My car will stop and shut down while driving. Ive taken it in for service and they told me my battery cabels were lose. The second time it happened I got a notification of low battery level and it shut off and will not start. I just replace the battery 2 years ago. The service department tested my battery and said it was fine”
