My new SpyTec A119 keeps resetting itself and always wants to format the MicroSD card.

So I just bought and had installed a SpyTec A119, since it looks the same as the well-reviewed Viofo A119 and was slightly cheaper. I put a Lexar 64GB card in, and the camera prompted me to format the card, so I pressed "OK", and then set the date and time.

It worked well for about a day. But since then, every time I turn on my car, the camera prompts me to format the card again and again, and keeps resetting the date/time to 1/1/2016.

Is there anything I can do, or do I need to get a new camera?

EDIT (5 days later): The Spy Tec tech support guy didn't know what to do, but suggested trying a 32gb card instead of a 64gb (which the A119 is supposed to be able to use, but hey). So I bought a SanDisk 32gb, which did the exact same thing. Finally out of desperation, I ordered a Transcend High Endurance 32gb card, and so far it's been working fine. Thanks for all your suggestions.
