I took delivery of a Mazda CX30 (in Australia) in March 2020. I have completed >1,900 kms.
Very happy with the car apart from a very annoying rumble noise on roads except for very smooth pavement.
It sounds like a body panel "vibration" rumble from the rear.
I cannot locate source. Can any forum members shed light on this annoying problem with an otherwise very quiet car? Thanks

 

You have a five year, unlimited km warranty. Book it in at your dealership, also ask ( at time of booking) to take the Foreman on a road test to demonstrate your concern.

 

Thanks for the quick reply. I will do so tomorrow. Now Tues night here in Aust.

 

Must be getting Cold in the ACT? Sunny Queensland is sticking to the 20's.

 

Indeed nights are close to 0C but days are lovely. Being an Aussie driver you will know the differing road surfaces. In Canberra sometimes they roll cold bitumen which provides a very smooth surface. BUT more and more they are laying hot bitumen layind blue metal stones and leaving for the cars to roll in. No brooming off. Those roads hv to be avoided due stone chip potential. They think they are absolved from responsibility by putting stone chip signs up.
BUT the other issue is the rough surface, and it is on those roads I get what sounds like body panel rumble.

 

Aussie driver?
Yeah, Nah Bro. All Blacks for life.

 

Oops. Kiwi eh!
BTW my adult son talked me into putting weather shields on the doors. They turned a quiet (no wind noise) cabin into a wind flutter. After 1 week I took the front ones off. Back to no wind noise. I reckon Mazda needs to go back to the wind tunnel on that one.

 

Where you driving with the windows down? or up?

 

Windows up.

 

I don't notice any body rumble and we have some really rough roads in Dallas, but I do hear slight wind noise. Not enough to complain about.
