That seems weird. I recommend you to submit a ticket to the warranty team by filling the following form: Intel Support. You will receive better assistance there. Please be as detailed as possible in the issue description.
Additionally, the issue with the Arduino sketch might be because of the image version. There have been known issues with the Arduino sketches using the latest image. The workaround described here might solve the issue: Run Arduino sketch on boot Workaround. Anyhow, I recommend you to submit the warranty ticket. The warranty team will contact you once they receive your ticket.
