Hello, on my second CEL at 7500 miles and looks like another DEF issue on my CTD. The first was a P24AE for a particulte matter sensor, now a P11D7, probable NOX sensor. Does anyone now how long the smog related components are warrantied for? I hope and pray its longer than 36 months or we will be paying for these issues out of pocket someday. :sad:

Thanks for the responces, I'm getting ready to contact my dealer for some clarity (I hope). As far as short trips or idling, my daily drive is 50 + miles each way, every day (no short trips). My average speed is 70 -75 MPH on the freeway and I do not baby my gas pedal. I did recently refill my DEF fluid but I get no messages like low quality DEF fluid and I did refilled with "Blue DEF" by Peak designed for use in SCR exhaust systems.

Tried to talk to the dealer about this problem this morning but now I'm still waiting for a call back. I was then going to go there in person at lunch today but when the wife picked me up, the CEL was off???

Well when the CEL went off, after about 100 miles, I didn't persue the dealer any further. It it kind of disheartening that after leaving a detailed message with service manager that I never got a returned call. I did call back yesterday late morning and was put on hold for way too long and finally just hung up. Possible dirt or soot on the NOX sensor I hope. Can Chevy clarify the warranty on the smog related components for us? Thank you for listening to our concerns, it really is an awsome little car.

Lights been off for 500 miles so I'm going to ignore it, maybe dirt or something on the sensor. I wonder if a loose fuel cap could trip CEL on a diesel? Even my 7.3 super duty has a cap that clicks and when looking at the CTD cap it has a valve of some sort built in it.Hmmmm but be a good question to bring up on a future forum topic.

Well its been 14,000 miles later and my CEL is back on again. Actually its been acting like a christmas light lately going on, going off, and back on. It has now been on for 600 miles so its back to my local dealer tomorrow. Anyone else having a re-ocurring CEL?

Well I'm at 15,000 miles now and my CEL comes on more than my high beams, every time I make an apt to drop off the darn light goes out, for a while. I bought a code reader last night and got the code P11D7, which I've had before. I have searched and I believe this is a NOX sensor issue, if anyone knows for sure please chime in on this. Looks like it will be going back to the dealer next week, ugh! I hope your right on the in stock inventory on the NOX sensor, and what the heck is this BS of "part restriction" from GM? The dealers should HAVE IN STOCK parts for the cars they are selling period! Or don't sell your cars to people put you cars on "selling restriction" until you have parts.
