Iv had the same exact thing as you since I took delivery of mine in February.. to me it seems like a blendor vent or something rattling inside the dash over sharp sudden bumps and rattling around sounds like something with the climate control blendor vent.
Lol at first I thought it was something I had inside the vehicle so I emptied it out down to nothing and went for a drive and at that bump at the end of my street I heard it still so same I just shrugged it off and though ah it's a lease and iv got full warranty so as long as things work no point in getting th dealership to tear things appart as hell only knows what could go wrong with electrical things etc so best to leave it I thought.
Pretty much the same thing for me as it seems to be the exact sound I'm getting at too.
Alright so I have noticed that it happens between speeds of 20-40 km/h after iv done some exsperimentation... It isn't there at higher speeds and I don't know if you have noticed the same but I will be very specific to my dealership when I bring it up as iv learned in the past when I had my pos Nissan Qashqai/Rouge Sport as I had a very horrible creaking noise at 20,000 km on the odometer.. after going into the dealership 12 Times yes I said it right no exsaderation.. 12 Times they finally figured it out and had to order both front struts and that fixed it.
have you tried at the speeds i said? if it is really noticeable then i would tell your dealership the speed you hear it most at as it will really help them in resolving the issue as i said in my previous post where i went into some good detail.....
to me it sounds like two plastic flaps slapping against each other under vibrations and jolting around from bumps and i really can hear it at 35-45 kmh and it isnt there at higher speeds as all this week iv been trying different things with mine as there are a few things that have to be done to mine when its in the shop. Recalls , new radar sensesor and a new front passenger wheel as the paint is lifting for no reason caused by me other wise it would be all the rims lol but its all good cus its all warrenty work and at the same time they are looking into the the rattleing noise that we are hearing and i told them what speeds its at so they are going to try it out.
hmm interesting .. mine is only over bumps. I know there is another thread related to any body not having any issues and i do want to say tho as long as the issues aren't related to failure of suspension components drive train or engine i Will definatly lease another cx 30 as i love the driving dynamics of the vehicle and the transmission feels great so what im getting at is that thread feels like its targeting people just complaining to just complain but in our case and in my case with my promlems im not complaining as both my issues have been verified with mazda warrenty claim and have been approved so just complainers wont get warranty work approved lol and i rest my case haha
