Did you ever figure out the starting issue My 2021 has a hard time starting after -10’c. It’s very rough starting from my garage 15’c! Is it possibly a tight valve? Battery is new. I was told to cycle it twice first. I believe the relays are updated after 2020. My 09 Nytro fired up perfect even at -30 until it had 30k and after checking valves found one tight. Shimmed and starting fine.
