P0031 and P0037 codes

[tcadrone]

2025 Grenadier. I filled up yesterday and got check engine light. Ok, known issue, bought a code thing from AutoZone to reset and it shows the codes above re a cat heater and O2 sensor heater emissions stuff. Permanent code so can't reset. Any ideas? Less than 1000 miles on vehicle

Definitely covered under warranty. Dealer should be able to get it straightened out.
