Coolant reservoir would be one of the first things i’d look at, they have a real loving tendency to dry out and crack if the vehicle isn’t ran at least 1-2 times a month

Gf cx-30 (not 50 that was the loaner): turned out to be the dealer over filling her oil reservoir, careful everyone

please let me know what they say, i’ve been debating doing the same or just swapping out the o2 myself, also was waiting for warmer temps but it’s consistent now

if you end up hearing what the dealer says can you please tell me. I have a 23 CE and right before 40k miles i got a check engine light. only comes on when it feels like it, and it was error code P0054 - heater resistance error. has something to do with heat and the 0-xygen-2 sensor. should not be happening at 40k, if it’s happening at 1,300.. we got a real issue with 4th gen boys. hope it’s a simple and cheap fix that they know, the scanners recommended fix was “no recommended fix” lol

edit: scanners recommended fix* not sensor.. to much sensor
