We have been experincing a loud vibration noise from the left rear area of our 2015 CX-9 somewhere near the rear tire (audio file attached). For some reason it occurs most often in the rain or wet conditions, generally during the first few minutes of driving. When we slow the car down the noise changes pitch and frequency and then comes to a stop. We have recently had our tires changed from winter to all seasons and that didn't stop the problem. There is nothing rubbing against the tire, as far was we can tell.

Our dealership has just chagned the rear wheel bearing and that didn't resolve the problem. It sounds like something vibrating and making contact with the car body or someting.

Has anybody else experienced this?

 

I heard that noise latley ! did you figured it out ?
