I have a 2014 Chevy Cruze Diesel with about 46500 miles now that recently the check engine light comes on with codes for the NOX sensors. I know one code is P11DC read by ONStar. The service guys had some other codes too but the problem is with the NOX sensors. They have replaced number 1 twice and number 2 once. I got the car back ten days ago from a 5 day in service trying to fix the problem (over the weekend waiting for parts). I have probably driven the car about 1000 miles and the light is on again for the same P11DC code. This has been going on since about 45500 miles but my daily commute is around 140 miles. Has anyone seen this type of issues and is there something that perhaps is not being reset or changed by my service department? I take it to the Chevrolet dealer where I bought the car.
