Garmin Edge 1040 Solar All Sensors Disconnect at the Same Time and then Reconnect at the Same Time During a Ride

I have a Garmin Edge 1040 Solar with software version 24.18. I have a Precision 4iiii Power Meter, and Varia Radar Light, DI2, and a Heart Rate monitor connected. 
They all have pretty new batteries.

So here is what is happening. I start a ride and they are all connected and working normally. All of a sudden, at a random point during my ride, they all disconnect simultaneously for several miles, and then all reconnect simultaneously.

Again, this is all random. It does not happen every ride, but it started 2 weeks ago.

The other issue, is during a ride, the Garmin will just randomly shut off or reboot even though it has 90% battery life.

I put in a ticket with Garmin Support.

Has anyone else experienced this? I'm thinking it must be a software issue since it just started a couple of weeks ago on 8/18/2024.

  • Yes I am experiencing the same thing.  It happens on most of my rides now. This began about 3 months ago. Have not figured out what to do about it.

  • I have not had this happen again, but now, my sensors don't always connect automatically. Very buggy software updates 

  • Yes.  Mine does this usually in the first five minutes after turning it on.  The sensors disappear for about five minutes, then reappear.  Not a problem with the sensors as I can also run my old Edge 530 concurrently with no drop out.  I put in a ticket to Garmin back in February and it is still a problem.  This happens on both of my bikes with different sensors.
