Service Emission System

Hello Everyone, I am new to this forum and have a 2015 Sierra Duramax. I am getting the error message "service emissions system see owners manual 175 mph until 65 mph max" I tried to pull the code but there was not any code showing on my code reader. I have made an appointment with the dealer however, due to the flooding here in Houston I do not know when of if they will be open any time soon. Any advice?

Thanks

If you are able, get it to a dealer not in that area. It will start limiting your speed quickly if you have to drive it much and will get to where it limits it way down. If you can't get out, I'd try to drive it as little as possible till the dealers do reopen and can get it in.

Did you get this fixed? I am new to this problem but recently my 2013 Silverado 3500HD Duramax is giving me this same message. But after I "tromped" on the gas a couple of times the message went away. Do I need to "tromp" on the gas pedal occasionally to clean out the emission?? I'm a new Duramax diesel owner and would like some help on this. Do I need to take my truck to a dealer? I would appreciate any help out there....thanks!

I ended up taking it to the dealer, they had to replace a component in my def tank, luckily it was covered under the power train warranty.

My 2012 just gave me the same message. I've been away from the Duramax forums a while, has this been a common problem with the LMLs? Is the delete a fairly simple procedure and what are the costs and benefits of doing so?

I had that happen at 98000 km on my 2012 GMC 3500hd, and the dealer replaced the DEF tank, the heaters quit, now another problem, at 125000km service emission system on DIC, so, dealer changed out 2 nox sensors and couldnít get it fixed and now want to change the whole exhaust system, Iím not letting them do that, so, here in New Brunswick we have no emissions testing, and with the warranty expired im looking at deleting all the EPA junk and installing a straight pipe with muffler, single tune, tow mode as thatís 90% of what the truck is used for, should have done that when the warranty expired.

This same message just came up on my 2018 Duramax with under 600 miles, I traded my 17 Powerstroke in last week with 17K miles because front hub went bad and first ford I've ever owned and the last.
unfortunately I fear my new Duramax has let me down today but the temp is -10 deg so I'm giving some consideration. When I spend 60K plus on trucks I don't want to be concerned I cant get out of driveway.
Not impressed
Any thoughts?
