Hello all, I'm new here so be gentle, please. I have a 2015 RX350. I have my cell phone connected via bluetooth. Everything has been working fine with talking on the phone through the speakers and microphone of the car for at least a year. But a couple of weeks or so ago we had a dealership replace the battery. Ever since then as we drive by an area that is a couple of blocks from our home we hear a "Bong Bong" sound like a doorbell through the speakers. The chime doesn't sound like the other notification sounds like an unfastened seat belts etc. It actually sounds like a doorbell inside a house. It would be nice if we could avoid that area, but alas it is a necessary street to get into our neighborhood and to our home. One thing that is puzzling is that the chime doesn't ring when we leave the area. The only differences are the car is facing the opposite direction and we're on the opposite side of the street. We haven't been able to locate the exact spot that it happens. It happens anywhere between a 200 foot range or so.
I've thought of running some experiments such as driving by there without my cell phone in the car, driving the car on the left side of the street when leaving,
At first I was a bit amused. I thought maybe it was causing someone's doorbell to ring and somehow we could hear it through our speakers, but that seems a bit far fetched but gives me a bit of a guilty feeling if it is causing that to happen. This weekend I will try those two experiments I mentioned and would like any feedback you could give me, and any other experiments that might isolate it to the radio, bluetooth, or a setting that may have gotten changed due to exchanging the battery.
Thanks, Bob

I suspect it is from your phone.
You could turn off bluetooth on your phone as another experiment so it will not broadcast to the vehicle.

Thank you, I'll do that in addition.
