2021 MERCEDES-BENZ C 300 4MATIC

Component that fails & available for inspection upon request? HVAC heat exchange and faulty gas gauge. I drive from Minneapolis to Warroad, MN frequently and the floor wells has insufficient heat hence impairing use and safety in Minnesota's severe climate. I have videos on the following but I am ... unable to upload videos to your site: (1) when I have heat on high, full blast and to foot well ONLY, the dashboard vent is 115-143 degrees (using a digital food thermometer) and a ~60 degree difference with the footwell at 65-85 (although 85 degrees sounds warm at 1 degree outside my feet are very cold - I would be happy to have you test this with me). (2) Brand new SUV consistently 1.5 - 3 hrs to warm up. I explained to Hyundai this is NOT a software issue rather an HVAC air exchange issue. (3) The gas gauge consistently underestimates the remaining fuel available by 50% in cold weather - an issue that between Bemidji, MN and Baudette, MN (102 miles/1hr 45min) there are few gas stations. On 11/11/2025 I took the SUV to first Bloomington Hyundai - they said it is working as designed. Then 11/20/2025 to Morries Hyundai said they are aware of a similar situation with the EON. However, without an "error code" Hyundai is unwilling to fix the air exchange. Additionally, I opened case#: XXX[XXX] -68 with Hyundai corporate - additionally they are unwilling to admit fault - this vehicle should NOT be sold in Minnesota's extreme climate conditions. How was your safety of others put at risk? If I run out of gas, my passengers and I risk frost bite or fatality of hypothermia. Has the problem been reproduced or confirmed by a dealer service center? Yes. Has the vehicle or component been inspected by the manufacturer? Yes. Were there any warning messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning messages have ever appeared.
