🚗 Bluetooth keeps disconnecting between my phone and my car, tried the usual troubleshooting already

My phone and car's bluetooth system have started disconnecting randomly mid drive over the past couple of weeks, no clear specific pattern I can actually identify, sometimes it happens within just five minutes of actually starting the car, other days it stays properly connected the entire drive without a single issue at all, which makes this genuinely difficult to actually troubleshoot with any real confidence about what specific change might have caused it recently. Already tried the fairly obvious basic steps, forgetting the specific device pairing on both my phone and the car's own system separately, then repairing them completely from scratch, updating my phone's operating system to the latest available version, even trying a factory reset specifically on just the car's bluetooth module itself through the vehicle's own settings menu, none of which actually resolved the underlying issue in any lasting or consistent way afterward. A mechanic friend mentioned it could genuinely be interference from something else entirely in the car itself, possibly a phone mount, a dash cam, or some other electronic accessory that got installed or added relatively recently around the exact same general timeframe this specific issue actually started happening consistently. I did install a new phone mount with a built in wireless charger about three weeks ago, which now that I actually think back on the timing more carefully, does roughly line up with when this whole issue first actually started occurring for me. Going to try temporarily removing the wireless charging mount for a few days specifically to see if that alone actually resolves things properly on its own, though I am genuinely not fully confident yet that is definitely the real underlying cause rather than just an unrelated coincidental timing between the two separate things happening around the same period. If that specific test does not work, honestly not sure what the actual next reasonable troubleshooting step would even be at that point, since I have already tried most of what came up during my own research into this exact kind of intermittent bluetooth connectivity problem. Has anyone else dealt with a wireless charging mount or similar accessory actually causing bluetooth interference like this in their own car, and did removing it genuinely fix things properly for you afterward?

Turned out to be my phone's aging battery in a similar case for a friend of mine, apparently a battery that cannot supply steady power under load can cause bluetooth radio instability that looks exactly like a car side problem at first glance. Worth testing with a fully charged phone on a short drive before ruling anything else out completely.

Updating the car's own infotainment firmware fixed a similar disconnecting issue for me after trying basically everything else first too, dealership mentioned during a routine service visit that older firmware versions apparently had a known bluetooth stability bug on my particular model. Worth calling your dealership directly to ask if there is a pending software update available for your specific car.

My dash cam turned out to be the actual culprit in a nearly identical situation two years back, the ones with a built in GPS antenna seem to interfere more than simpler models based on what a car electronics guy told me afterward. Moved the dash cam power cable further away from the bluetooth module itself and the constant disconnects stopped completely.

Had the exact same wireless charging mount issue in my own car last year, removing it completely stopped the random disconnects within the same week, confirmed it definitely was the actual interference source once reconnected without it for over a month straight with zero issues afterward. Worth checking if yours has any kind of shielding built in before buying a replacement mount.
