OK I know this sounds weird but hear me out. We just noticed a very faint beeping sound coming from the rear of the car when turning. The radio is off and it is very faint, but it's about 5-6 chimes. It sounds muffled.We had a passenger in the back seat this past weekend and she heard it too! It doesn't happen every time we turn but we have heard it more than once. We have not tried to repeat it under different scenarios but was wondering if anyone else has experienced this? It's really quite strange!
