Why does the dash cam automatically shut down right after startup?
2 Answers
Possible reasons include a faulty memory card, low battery, loose power connection, or software malfunction causing system lag. The specific causes are as follows: No memory card installed: Many dash cams may automatically shut down shortly after startup if no memory card is installed. If a card is installed, verify whether it is a Class 10 high-speed card. If not, replace it (this is highly relevant to the issue and should be prioritized). After confirming this, check again whether the battery is low. Faulty memory card: Due to prolonged use, memory cards can develop issues after repeated friction. In such cases, formatting the memory card on a computer usually resolves the problem. If it's a newly configured memory card, incompatibility might be the issue. Loose power connection: This is especially common when using a multi-port cigarette lighter adapter. When the power connection becomes loose, the dash cam will automatically switch to its built-in battery, which typically doesn't last long. As a result, the dash cam may appear to be on but is found to be off when checked later.
If the dash cam turns off immediately after powering on, I think the first thing to check is the power supply. Possible causes include unstable power from the cigarette lighter socket, poor contact or aging/breakage of the provided data cable, which can all lead to power interruption. Additionally, the dash cam's battery might be aging or too low on charge, causing it to shut down automatically as soon as it powers on, especially noticeable in cold winter temperatures. On the hardware side, a full or damaged memory card can cause the dash cam system to malfunction and stop working immediately. Firmware bugs may also trigger abnormal shutdowns, such as conflicts arising from an unsuccessful update. Based on my experience, I recommend first trying a new charging cable for testing, or moving the car to a shaded area before starting to avoid overheating protection activation. Regularly clean the memory card and check for firmware updates to prevent the accumulation of such minor issues.
