My truck is showing the same message this afternoon.  I have an appointment with the dealer tomorrow to have it looked at.

I got the truck back today from the dealer.  The truck was throwing a  P122D code, which is a throttle valve position error.  Testing showed the valve did not return to the closed position when the engine was shut down. The throttle body was replaced and that resolved the issue.  Seems unlikely but it's good so far.

I was having the same issue, message on the dash, 2020 2500 Duramax HC with 31,000 miles. I ended up at the dealer because I was unable to locate anything plus it is still under warranty. I dropped it off and there was a 2021 3500 DRW sitting in the lot with out of state plates. They gave me a loaner car to get me around. So after about 4 hours, I get a call and was told that the connector on top of the DEF tank had melted. I was also told that this has become an issue. Finding out that the DRW that is in the parking lot did the same thing. That truck has been their for two weeks.

 

It has now been 4 weeks, I called after 3 weeks, I am being told that they have not been able to get the part(s) that are needed. According to the service mgr, they have talked with their GM rep and they don't know when the parts will be available  I asked about the DRW, I was told that it was still there.

I have always driven Honda/Toyota cars.  My husband buys this $50K Chevy Silverado Truck.   The DEF system constantly breaks down.  We can't go on a trip without it having an issue.  It is currently at the dealership and they can't fix it and they don't know when or if it can be fixed.  They have 6 new Chevy trucks sitting there that they are trying to fix.   I just don't get why anyone would buy a GM product.  This is beyond crazy, especially for someone like me who has had 40 years on dependable vehicles.

Can you GCWR 40,000 with your Honda?

We have a small farm with a small tractor, but right now I could pull his trailer with my SUV through the field better than he can, because his truck is sitting at the dealership, with timeframe unknown.   This has been going on since February.  Pretty worthless $50k.  Have you had to replace your rear panels from rust yet?  Or your injectors?  Good luck with your junk.

Nope. Not yet. '22 w/ <4k miles, '21 w/ <30k, '19 w/ <42k, '15 w/ <98k, '93 w/ <248k, '90 w/ ?, speedo broke in '95. The last 3 are gas burners. 

 

I know you are upset, but you didn't answer the question, I put forth to you. Sounds like a liberal. Deflect. Question was a yes/no, I try to keep it simple nowadays.

I am politically relaxed - which means I think for myself.  I don't need a political party to tell me how I am suppose to think.  I don't belong to either cult (far right or far left).    You obviously believe in your Chevy's regardless of their quality.  That is exactly where GM wants you.

Your pics look like you have to work a lot.  I drove Hondas/Toyotas for years.  They allowed me to save enough to retire at age 49.  Guess you couldn't do that.  Have fun with all of your work trucks.

Based on every one of your comments, i dont think "relaxed" should ever be used do describe anything about you.  Enjoy your Honda's!  One more thing, if you are comfortable enough financially to retire at 49, I dont think a $50k truck should make you fret.  Enjoy your retirement.

Just trying to feed people's mouths with food. Great gpa, gpa, dad, myself and 2 of my boys are following our footsteps. Started with horses and the way it's going, will be back to horses. It takes work trucks to farm. With these emissions systems failing and not allowed to operate without them, it's going to get bad.

 

If more people returned to farming or what some call work, we could do without the large equipment, which DEF emissions is part of now. But no, people wanted the easy life, move to the city and retire before 50.

 

I will bet my life's earnings, you will eat food until you die.

I own a small farm (40 acres - corn and beans).  I worked for a fortune 50 company for 30+ years.  This company made products that literally lasted forever.  I remember the meeting where it was decided that if our products lasted forever, we couldn't make money in parts.  That is when Engineering changed to planned obsolescence (ie designed to fail).  GM is doing the same thing.  They all are.  Don't fight it, obviously they have everyone brainwashed into accepting it.  In life, you get what you accept.

      Well one of our most reliable vehicles was sold yesterday. The first and only I gave for free to a grandkid. If they got skin in the game they take care of it. My wife bought new. Five years later my daughter got it to use. We got it back and gave it to our grandson after graduation. He did zero maintenance just oil changes. When the AC quit he drove his mother’s car rather than get it fixed. Instead he just bought a beater and sold the Elantra.

      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.
