Engine light came on again yesterday, P22FA code for the NOX sensor. :angry: Two months ago it was for that and they cleaned it, and it has been OK until yesterday. Appointment next Thursday. With all the recall work that's as soon as I could get. Two P22FA NOX codes and one PO133 OX sensor code in 4.5 months. They always fix it, no problem with the dealer, but with these little problems causing multiple trips back, it won't help the Cruze diesels reputation. Other than these environmental sensors, the car's great.
