2017 Maxima SR. My AV navigation screen started rebooting over and over with no stopping it. The only way to keep the screen from rebooting is to remove the SD card. It only gives basic functions at that point and does not keep memory of bluetooth devices, stations, etc. Navigation is also not available at this point.

Now.... My AEB warning light comes on and off over an over, but only after the car has been running for a while and only when I am stopped. I see a message of "front radar obstruction either in park or in drive with the brake on at a red light. It is quite annoying to hear over and over, not to mention the fear of the brakes possibly being applied randomly.

Intelligent cruise control works 99% of the time.

I have cleaned all the sensors/sonar/radar. Any ideas as to what is wrong? Maybe something electrical? fuse? Bad SD Card? I'd rather not pay hundreds to go to the dealership.

Thanks
