Best sun shade for Toyota Mirai windshield?

I went through this last year. IR radiation penetrates glass, heating cabin surfaces. I found the WeatherTech SunShade for Toyota Mirai fits that sensor housing perfectly. Tip: Use high-reflectivity silver for max cooling!

TIL! Thanks for sharing

Hi there, and congrats on the new Mirai! I totally get the concern about that massive sensor housing—it's definitely a tricky fit.

In my experience, I would suggest going with the Covercraft Custom UVS100 Sunshade for Toyota Mirai. I've been using it for a while now and honestly, it’s the only one I’ve found that clears the rearview mirror assembly perfectly without leaving those annoying gaps that let the heat in. It’s a thick, accordion-style folding shade, so it feels really sturdy and protective for the dash.

That said, just a quick heads-up—it's a bit bulky to store when you have passengers, and because it's so stiff, you have to be careful not to knock the mirror when you're setting it up. I’m always a bit cautious about putting too much pressure on that sensor housing, so just take it slow the first few times. If you want something easier to roll up, the WeatherTech Custom Fit SunShade for Toyota Mirai is another solid bet, though I think the Covercraft feels a bit more heavy-duty for that intense California sun. Hope this helps!

To add to the point above: getting a custom fit is absolutely the right move for long-term reliability! I've seen way too many dashboards start to peel or crack because someone used a generic shade that left gaps. Those sensors are super sensitive to heat soak, so you really want full coverage. It makes a huge difference. Just curious tho, what kind of storage space are you working with in the Mirai? Are you looking for something heavy-duty that folds up or do you prefer a roll-up style that's a bit quicker to handle? Also, do you have a specific budget in mind?
