Because of the oil dilution recall, um,update, Honda reprogrammed the ECU so that all of the heat stays in the engine to burn off the fuel that was getting in to the oil at idle and in cooler temps, instead of heating the cabin. You can leave the car in idle for 8 hours and it still won't heat up or defrost your windows. On my 2018 ex-l, the temp guage will not even register until I've driven for 5-10 mins. I'll be taking it in, again for this very problem. 12th and last Honda. .I just bought a 2019 CR-V in June (3rd one). When I would use the auto start, the car would automatically turn on the heat or a/c on full blast to get the car to 70 degrees. Now, when I use the auto start, it just turns the car on and that's it. I don't know if I changed something or if something is wrong with the car.
