But even the earlier CX5's were not nearly as noisy as some people here like to claim. Had a 2013 GT diesel myself. Yokohama tryes on that one from new. Second set were the same. I can not recall thinking to myself "gee this car is noisy" when I first got it. Just didnt happen. Stepped out of a late model SV6 Commodore sedan before it, itself a fairly quiet ride.
It may of course depend on what you had as a daily drive before the CX5. Like any wagon style vehicle, compared to a sedan, youre always going to get more rear wheel noise into the cabin. So everything is relative to your most recent experience.
I think the same applies to people who think the CX5 brakes are spongy - every car I have driven, the brake pedal is different, and you quickly get conditioned to the one you drive regularly. Step out of one that has a sensitive pedal that picks up high up, and into one that is more progressive and requires a firmer foot, then its gonna feel different. You just need to acclimatise your foot and brain to the new one. Some brains take longer to adjust though, apparently, and want to "blame" the new vehicle.
The MY 16 is definitely quieter, and no doubt the 17 is a big step ahead again.
Chuck a set of unsuitable tyres on it and it will have an impact too.
