I purchased my 2014 Cruze diesel a year ago with 28K miles on it in southern California where I live. Its been running really well and I've been a happy camper (other than finding out that the car MPH gets reduced when it needs more DEF!) A few weeks ago the CEL came on and its staying on now. After checking recalls, I chalked it up to the NOX sensor recall but the local dealer says mine had the sensor replaced last year. It's been running normally after the CEL came on until a few days ago when I filled the gas tank.... when I restarted it the display started showing the following.... "Service Exhaust Fluid System" followed by "See owners manual Now"... then followed by "90 miles until 65 MPH Max Speed". If anybody can shed some light on this I'd truly appreciate it.
