2017 Hyundai Elantra — wireless CarPlay drops at the same intersection — buyer question from Orange County

2017 Hyundai Elantra SE, about 139,000 miles. 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? I am in Orange County. Interested in real owner experience more than guesses.
