Emission Warranty

warloc said:

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:

I replied to you in the other thread - but for everybody else, I think federal warranty is 8/80 and Chevy powertrain is 5/100, so figure 8/100 on these components. Someone correct me if I am wrong on this.

Beginning on page 23 of your owners manual......kind of tough to follow but the majority of sensors seem to be 3/36 gasoline or diesel.
There are some components, marked with a asterisk, that fall under 8/80 on non-California models.

I read it three times....rather vague.

I have found though, the Nox sensor acts up a lot if the car is extensively idled or short tripped.
Not enouph heat is built up for long enouph periods to keep it clean.

I don't think the emissions sensors are going to fall under powertrain, so probably just the 8/80 federal emissions warranty.

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???

UG!

Intermittents.....a real pain but the code is in memory.
What has happened is the computer recieved input from the nox sensor that was out of range.
Maybe a carbon buildup or something going through the exaust that it 'saw'
Anyways, it hasn't seen the problem again for a predetermined running time so it shut the light off.
The code will sit in 'pending' for several start/run cycles and if it continues to send viable information the computer will discard the code.

For now, keep on keeping on.....might have been a fluke, never to be repeated.

Hi warlock,

I will be glad to assist you with your concern. I’m sorry to hear that you may be having possible DEF problems. I understand that you tried to get in contact with your dealership today regarding your warranty questions. Have you spoken with them yet? Please feel free to send a private message with your VIN included so that I can look further into your concern. Thank you.

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.

Sorry to hear about your issues. Is your dealer very far away, if not, go there in person. I rarely call many places if I'm having issues for reasons you describe. It's too easy not to call back, not to get a straight answer, or be outright lied to over the phone.

Ugh, I am not a fan of poor customer service. Have you made any progress on this?

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.

Interesting that the CEL disappeared. Keep us posted.

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?

8/80 federal emission warranty only covers the catalytic converter and the ecm/pcm.

I've never had a CEL on mine in almost 60K miles. Keep us posted, I am very interested to see what the issue is.

I have an Oxygen Sensor Slow Response Bank One CEL - Code P0133 reoccurring. The CEL occurred twice after highway driving upon decelerating when getting off. The CEL was reset by 2 different dealers 3 times and has still reoccurred. It is currently on now. I have 5700 miles on my car. The part is on an "unavailable status" since Nov. 2013. This has not affected the drivability of the car. A TSB was issued By GM for this problem. There appears to be no apparent solution other than waiting for a new revised part to become available from GM. Some others of you have reported NOx sensor issues which apparently were resolved with the currently available parts being replaced with in-stock inventory. I also am wondering if anyone else has had this Oxygen Sensor issue with their Cruze Diesel? This all has happened in the past 3 weeks. This is the first issue that I had since I got my car last October, 2013.

Not to open another new "can of worms" but after reading GOTDIESEL?'s blurb on Biodiesel it got me to wondering. I have used only the mandatory 5-20% Biodiesel Blend in my car since new because that is the only fuel that is available here in Illinois because it is subsidized by the state. The Cruze Diesel is certified to use this range of Biodiesel Blend. I can only hope that GOTDIESEL?'s speculation that Biodiesel Blends maybe instrumental in premature failures of both Oxygen and NOx sensors is not true. I guess only time will tell.

I would be interested to know the build dates of the cars with issues. I have one of the first off the line. Also, I am pretty sure I have run a fair share of bio through the car. I never read the pumps, but have fueled up in IN, OH, WV, PA, NH and MA that I recall.

I stopped at my selling dealer today as I was driving by on business. I saw 3 Diesels available in their used inventory (interesting resale information forthcoming in another post next time I get to my office with time on my hands). Anyway, one of those Diesels was the 17th vehicle off the line of 2014 (#100017) - now that's an early build!
