Is anyone having trouble with DEF heater going out and Engine light coming on. Several friends have 2015 2500 Duramax and heaters going out. I called dealer yesterday (11/10/17) And new e-mail out saying GM is revising warrantee on this part for 12 years or 120,000 miles. So GM has noticed that there are problems out there with the DEF heater.

DEF & DPF systems on these trucks SUCK.  VERY common issue.  I got a new DEF system last year when heater codes started to be thrown.  Sadly I'm now dealing with DEF quality issues and am now limited at 65 MPH and 50 miles until limited to 55 MPH and so on.  Most likely the NOX sensors but I am out of the extended warranty on the emissions system as of this year.  Don't have the money right now to go get it fixed so truck is sidelined for the time being.

Had the exact same thing happen with my 2012. Heater went out causing the slow limitations of death. Part was covered under the extended warranty but was on national back order. Traded the Duramax in for a GMC 1500. Would love to get back into a Duramax but don't really want to deal with the emission systems again.

Even the 2017 models are having DEF/DPF issues.  Very sad that GM can't get it ironed out.  But Dodge and Ford are not much if any better with their systems.

That's what we all think.  There is just too much emissions and computer controlled crap on vehicles now a days.

Been test driving a used '17 for the last week. Don't really need the diesel and we have nothing but issues with DEF big trucks at work in the -30c winters in Canada. This kind of leans me to passing up the opportunity and waiting for a 6.0L.

MY 2017 GMC SIERRA 3500 HAD THE DEF HEATER FAIL AT 20K MILES  DEALER REPLACED ONLYT TO HAVE IT FAIL 2 DAYS LATER  TRUCK IS BACK AT DEALER FOR 2 WEEKS NOW WITH DEALER UNABLE TO FIX, CHNGED DEF HEATER AND MODULE  NOW CLAIM GM ENGINEERING HAS TO FIGURE IT OUT  LOST TRUCK FOR PLOWING A BIG STORM, NOT TO MENTION THE MONTHLY PAYMENT  CALLING GM CUSTOMER SERVICE IS A TOTAL JOKE- MANNED BY FOREIGNERS AT A CALL CENTER

 

IVE NEVER BEED SO FRUSTRATED IN MY LIFE.  WE OWN SEVERAL OTHER PRE EMISSIONS DURMX TRUCKS- MY ADVICE; STAY AWAY FROM ANYTHING WITH DEF!!!

New here to the forum. I had the same problem as above. I have a 2016 Sierra 2500HD Denali Diesel and the DEF heater went around 36,000 miles. Dealer replaced it and two days later the engine light came on again and they had to replace the one they just installed. I'm up to almost 40,000 miles and no issues.......yet.

Ford had a bigger issue causing theirs to shut down....I had the DEF heater, common problem. Blame the EPA.... not GM.

Causes one to wonder when the U.S. OEM's will wake up and do it right.  Amminex, a Dutch company, has been making cartridge systems for quite a few years that contain 100% urea in a substrate that eliminates all the DEF nonsense.  Cartridges last for a complete oil change interval.  Pull one out, put the other in and go.  No shelf life issues, no freezing issues, no spilling, etc.  Cartridges are recycled and refilled.  Simple plug and play cartridges that can be purchased at fueling locations or delivered right to your front door.  Since the system is totally functional on engine start up,  EGR  can be eliminated and still meet EPA limits for NOx at start up.  

 

DEF is soooo old school.

      OCI, not when but why?

      I usually do as well or better than the sticker for mileage. Usually better going west than east. North then South. Wind makes a difference. I’m not usually a conspiracy theorist. But it did dawn on me I’m going by the vehicle calculation. Now that would be interesting.

      What’s missing in all this is patience and investment in the future. Buy a 170K starter home. Ten years later sell it invest in a more expensive home. Eventually you’ll have a 600K home and pay starter home payments. Buy a starter car. Maintain it well. Save the payments after it’s payed for then buy an expensive car if you desire. Buy a tumbler make your own coffee, pack your lunch. Cook your own dinner. Most importantly take care of your car.

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.
