    Hello,
    I am a first time owner of a used 2018 Prius Prime. I've had the vehicle for 2 weeks now and I do enjoy the electric range, safety features and overall experience. However, I've noticed two things now about the car which I am not sure if it's me or if they're Prius quirks that others have experienced. The first thing is really bad fogging of the windows. Lately it's been below freezing here in Maryland and when I get in the car, the windows will fog up badly. Every window will have moisture. I'll use the defogger button on the center screen stack and it'll barely make a dent in the amount of moisture in the car. It doesn't seem like anything I do can help. I've done cold air, nothing, hot air, nothing, nothing seems to work. I have a SUV and never have had an issue with fogging up. This is the first car I've had this with. The second issue is the USB port. When I plug in my phone and try to stream through the USB to the infotainment system, it'll vibrate like its connecting or randomly drop. I took it into the dealer and they said the fogging issue was due to dirty windows. Mind you it's only 2 weeks old. They said the USB is fine. The technician said that the Prius can only stream music via Bluetooth and not by USB. The USB is only for charging your phone. Is this the case? I would have figured a car from 2018 with USB ports would stream music through the USB port into the infotainment system. What's odd is that in the infotainment screen, there is a setting to connect directly to the phone via USB and play music. But again, it drops and acts glitchy. I am sorry for the long rant or if these topics were covered elsewhere. Thank you for your time in reading this and hopefully helping me find some answers. - Patrick

    Do you usually operate with Recirculated or Fresh air on the climate control system? Recirc will tend to bottle in moisture, which is emitted by even occupants breathing.

    Have you removed any items storing moisture? Coats, boots, towels used at the gym or to wipe off windows. Even wet floormats or carpets. Though since carpets can't be removed, other means are needed to dry them out.

    congrats and welcome!
    the slope of a prius windshield is conducive to fog. you may have to run the engine to remove the fog, the main defrost button will do that. there's a reason toyota has that button start the engine as well.

    I use the Fresh Air setting because I know it'll pull in the outside air which should equalize the air in the car. I also have no items in the car that would be bringing in moisture, besides myself and passenger. We have rubber floor mats in the car which came with it. It just seems that no matter what we do, moist air keeps appearing.

    I've noticed that the air, even when on high, will seem to almost loose momentum. I am not sure if this is the air compressor switching from battery to ICE back to battery. The one day we had the defrost button on for almost 30 minutes and it didn't seem to completely remove the moisture from the front windshield. Would the windshield being dirty have such a large impact on storing moisture? We have only had the car for two weeks and haven't cleaned the windows since the dealership would have, when we picked it up. Even having the rear window defogger doesn't seem to compeltely remove the moisture. The one evening on the way home, you could see it forming droplets on the back window.

    Would you suggest starting the car up in the morning and letting it run while plugged in? We usually charge it at a certain time each evening, rather than the departure time with the climate option.

    I am fairly savvy when it comes to cars, but It's just a bit frustrating because I have a SUV and we get in it and drive in the mornings, we haven't ever had an issue with it fogging up. I've always wanted a Prius Prime, but this has been a little off-putting.

    Turn on the blower to Window with A/C on and make sure the recirc is off. This should take care of fogs most of the times. I rarely have to use the main defrost for my car. For streaming phone, try using the Bluetooth instead of USB.

    To give an idea of what I was dealing with today. It was 28 degrees and very dry out, but it looked like a steam room inside the car. The first 5 minutes on battery were fine, but then it steamed up. We turned around and came back home because we couldn't see out the front other than a small oval from the defogger. I'll get the car back tomorrow and will try everyone's suggestions.

    the heat pump, aka compressor, only runs off the hybrid battery. the battery is kept charged by the engine, after you run out of wall charge.

    prime is toyotas first foray into heat pumps, but it can only produce heating or cooling, not both at the same time, like when the engine is running.

    I've had this problem on my 2017 Prime and also on my 2010 Prius. I found that slightly cracking a rear window tends to clear it up. Makes the climate system work a little harder, I guess, but I rather like seeing where I'm going.

    I wonder if the Air Conditioning is functional?

    There's a sight glass under the hood, to check if the charge is sufficient. Typically you want to see little-or-no bubbles while the compressors running, and a little swirl of bubbles when it's stopped.

    There's also a glass humidity sensor; maybe it's not working?

    Would this be warranty item?
