A couple times each winter when the temperature dips to the teens and below, the washer fluid in my CX-9 freezes up. The first time I took it to a shop (needed a clean windshield for a road trip) and they defrosted the reservoir and pump. It's happened a few times since including right now as it's pretty cold in the Northeast. I typically buy fluid that is rated for -10 or -25 but I don't know how truthful those claims are. I'm just wondering if others have this problem and if there's anything about the CX-9 that makes the washer fluid system more susceptible to freezing?
