    Air Conditioner- Weird burnt plastic smell

    Registered to reply to this. I had the exact same issue start within the last week on my 2018 CX-5 with about 13k mileage. Started with just the burnt rubber smell after AC/heat ran for about 10 minutes. Then last night I stopped to check the mail after a 15 min drive and noticed smoke coming...
