I bought my Mazda CX5 new a 2015 model year and experienced a thumping noise when we slightly put rear windows down. It wasn't just a noise though, the pressure in the car changed and caused both my husband and myself headaches. I have reported it to the service manager at the dealer we bought it from and they said the manufacturer is aware of it and they have a fix for it but you have to purchase it from them to get rid of the noise. I have read of the same complaint regarding the 2013 and 2014 years. If I had known about this problem and the fact that all the manufacturer will do is charge for a fix instead of fixing it two years ago, I would not have purchased this car. I don't think rolling down the rear window should cause pain. I have owned this car one whole day.
