I considered Rain-X on my headlights, but there's a nice warning on the bottle to not use on plastics unless approved by manufacturer . You've had no problem? Good to know.As a winter driver in Minnesota (recently voted to have the worst winters in the USA), I am somewhat amused by all of these comments. Unobtanium, you did not say/specify whether or not you used the rear wiper while driving in the snow. Yes, on almost any vehicle with a near vertical rear window the snow will compact. But the use of the rear defroster in conjunction with the wiper WILL keep the swept area clean. Folks that drive in this kind of crap on a regular basis know this. Also, sometimes a judicious shot of washer fluid (the kind designed for winter use, not the summer crap) will assist in keeping the window clean as well. As far as the front defroster goes, as I've stated before, since my 2014 has thinner glass than the 2016+'s, mine works fine. And I have driven in winter temps approaching -30°F. Use the same approach to the front windshield as for the rear window; keep the wipers moving, keep the defroster blowing and use the occasional squirt of the appropriate washer fluid. And the side mirror defrosters work well too, but don't expect instantaneous results (yrwei52, sounds like yours need to be checked out by the dealer). As for the headlights, I use Rain-X on them when I prepare the vehicle for winter. Combined with heat from the HID's (in my opinion, the best headlights ever offered on the CX-5, bar none), I've never had a problem with the headlights being obscured by snow/ice. My headlight lenses look just as good today as the day I picked up my CX-5; crystal clear. Oh, and if you don't want those giant snow boogers building up behind the tires, install mud flaps and your boogers will be much smaller. And be sure to kick 'em off next time you are stopped somewhere to keep your CX-5's clean lines looking good (but not in your garage; bad ju-ju)! The heated seats are adequate; if they're not, you aren't dressed appropriately for the weather you are encountering outside the vehicle. It's not a living room, it's a transportation device. And as always, practice safe driving by ALWAYS cleaning the snow off your vehicle before you start to drive it, even if it's still snowing.
