I am experiencing an issue with my 2019 Camry XSE. Four days ago, the vehicle failed to start without a jump from another car, producing only a clicking sound. After jumping it a third time, I took it to AutoZone, where tests on the battery and alternator indicated they were functioning properly, although the battery was significantly depleted and required charging. After charging the battery fully, the car started without issue and I drove it home. However, this morning, while attempting to start the car for work, it again clicked without starting, but eventually started on the second attempt. After work, it failed to start on the first attempt but did start on the second. What could be the underlying problem?
