For the past two weeks, my phone disconnects from my car's Bluetooth every day at the same red light. As I approach the light, the connection drops, and once I get past it, it reconnects automatically. It sounds strange, so I'm wondering what might be causing this odd behavior.

It could be due to radio interference. Sometimes, signals from nearby electronics can mess with Bluetooth connections. It's worth checking if there are any other devices around that might be causing a disruption.
One possibility is that there’s a radar system associated with the traffic lights that might be interfering with your phone's Bluetooth. I’ve had a similar issue with a key fob in a parking lot where I had to unlock my car manually; it never worked out what exactly was to blame.
Most likely it’s just RF interference from something near that intersection. It wouldn’t be surprising if there’s something around that messes with your phone’s signals.
I’m no expert, but have you noticed if you’re losing cell service too? If there’s a jammer nearby, it could affect Bluetooth, WiFi, and even your phone signal by creating noise across various frequencies to disrupt connections. Maybe someone set one up just to mess with drivers.
