Check engin light
2025 equinox purchased 1-4-2025. At 600 miles check engine light came on. 2-19-25 very cold outside (20). Next day light went out and was good until today 11-27-25. Cold outside (30). Calling dealer tommorow.

That's likely a loose gas cap or an EVAP system sensor acting up in the cold. Tighten the cap until it clicks three times. If it comes back on, the dealer will need to pull the code. Common on new ones.
