2017 Hyundai Elantra — wireless CarPlay drops at the same intersection

Wireless CarPlay is reliable almost everywhere but disconnects at the same intersection on my commute. Does consistent location point strongly to RF interference, and what would you test to confirm?

Start with the test that can prove you wrong. Get a real battery/charging test on the 2017 Hyundai Elantra, not just resting voltage, before blaming a module. Save the big job until that test fails. Take it or leave it — that's what I'd do. Not driving it hard until I know more.

If it were in my driveway, if a shop can't duplicate it on the 2017 Hyundai Elantra, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. If you share a photo of the worksheet, easier to sanity-check. If this is nothing, great. I want that in data.

Checked the easy stuff on the 2017 Hyundai Elantra and found one clue worth chasing before I book a shop. This is the version I'd tell a friend.
