Sounds like a control issue with the onboard FM receiver chip. If reapplying the firmware doesn’t fix the issue, it’s likely a simple hardware issue. Troubles with the FM receiver are rare as hen’s teeth, rest assured.
If you just purchased the device via Amazon, their return process is great. With any retailer, within the first 30 days, returns to the seller are simplest. Beyond this, SanDisk has you covered. I’d exchange the little guy for a new device.
Reference the steps you have taken here, and they’ll fix you up.
