What Causes a Dash Cam to Keep Powering Off and Restarting Automatically?
2 Answers
Power wiring faults, memory card issues, or problems with the dash cam itself can all cause it to power off and restart automatically. Below are the three main causes and their solutions: 1. Power port malfunction: Take it to an auto repair shop for inspection. Check the dash cam's wiring, unplug its power connector, and try reconnecting with a different power cable. 2. Memory card failure: If the memory card has poor contact, place a small piece of paper behind it for better fit; if the card itself is faulty, remove and format it. 3. Dash cam malfunction: Reset the dash cam to factory settings. If the issue persists, contact after-sales service for quality inspection.
The dashcam automatically shuts down and reboots, and as an experienced driver, I've encountered this several times. The main reason is unstable power connection, such as a loose cigarette lighter socket or aging wiring, especially on bumpy roads where it's prone to disconnect and then reboot upon reconnection. Another common issue is overheating—prolonged driving or exposure to intense sunlight can cause the device to overheat and shut down as a self-protection measure. Additionally, a full or corrupted memory card can lead to crashes when the device can't handle large video files. I recommend first checking the power cable and card slot, and trying a new formatted card. If the problem persists, check if the car's voltage is stable, as some vehicles with unstable alternator output can trigger protection mechanisms. For regular maintenance, remember to periodically clean the card and avoid placing the device in high-temperature environments to prevent frequent malfunctions and ensure reliable recording.
