The finaly put in a new transmission. Then, a week later, my DEF injector failed and had to be replaced. I'm not having the best of luck with this truck. When it is running, I love it. It tows my 5th wheel like nothing. I am just not very confident in it. I purchase a roadside assistance plan with unlimited towing from Good Sam.

I feel like an extended warranty would be the minimum they should offer. It makes sense, if they are telling me it is not a lemon, they should be willing to stand behind it with a warranty. I hate the idea of trading it in. Even if I came out ok on the money side, that seams like I am passing the problem along, and GMC is getting away with selling me a defective truck. I have a feeling that I will take it in the shorts, financially, with a trade in.

I keep getting emails from GMC telling me that they are working with my dealership on a buyback. But they have not given any details.

I'm hoping GM steps up with something. It would br great if they did a buyback or my purchase price toward a new one. I'll see what they respond with.

I talked to GM about a buyback. They are supposed to get back to me.

They have emissions inspections every two years here in Arizona. I got the diesel because we purchased a 38' fifth wheel. The truck pulls it like nothing. Almost all of the miles are towing down the freeway. So it is not having problems for lack of getting up to temp or putting around town. I sold my F250 with the 6.4 gas engine. The mileage was not horrible on that truck, but I never had a lick of trouble in 135,000 miles. My son has that truck now.

Thanks for the reply. I have 14,000 miles on it with 3 major problems. At this rate, I am almost guaranteed to have some kind of major failure in the 4,000 plus miles we will be driving. I have to be back in 10 days, I cant afford to be waiting at a dealer in Oklahoma for parts. I don't know what to do. I am looking into the Good Sam roadside assistance. At least that would cover the trailer as well. But, even having towing coverage, and a warranty, doesn't fix a ruined trip. I am going to Ohio to pick up a couple of ultralight aircraft with my 18' flatbed. If the trip is interrupted, I will have to take more time off of work to go at another date. Not sure what to do.

The dealer got the DEF injector fixed. I guess I am taking it to Ohio. I am a little nervous. I don't want to go into limp mode half way to Ohio. With everything that has gone wrong with this truck, should I get rid of it? Is it a lemon? Should I ask GMC for an extended warranty because of all of the problems it has had in so few miles? My warranty will time out long before my miles ever do. Maybe I should try to push for a buyback. Any opinions? Richard

I booked a rental truck in case it is not fixed in time. It will cost me about $1,500 not including fuel. Not happy at all. Richard

I just posted it there. Thanks for the heads up.

I have a 2020 GMC 3500 Duramax with 14,000 miles on it. I have had the Particulate filter fail, the transmission failed (they put in a new one), and now the DEF injector failed. All of these are high dollar items, and my truck has been down for a significant amount of time. I am supposed to drive from Arizona to Ohio next week, if they have it fixed in time, and am a little worried about reliability. I am also concerned about about what happens when my warranty is over. Any advise? Richard Hlem

Great news! The dealer called me and they are putting in a new transmission. The Dealer and GMC came through. I am very happy. I love the truck but was disappointed with the thought of having a rebuilt transmission. Mechanical things can break. No matter how good they are, they are still machines, built by people, and they are not immune. How a company takes care of their customer when something does happen means everything. I don't think I can ask for more. They are saying I should have my truck back by Friday.

The dealer just got back to me and GMC will give them $44 a day for a rental, he said "you get what you get", meaning whatever $44 per day will get you. If you have a business that requires a truck, you are out of luck. They have had it for almost a month now.

When I told the dealer I wanted a new transmission, the service manager told me that GM doesn't like to give those away, and that they are really expensive. I told him no kidding, I'm still paying for my broken one. How do you say something like that to a customer? I created a case #, last week, with GMC. I told them I wanted a new transmission, and the reasons why. They said they would call me back, but have not done so yet. I requested a rental from the dealer and they said they would look into it, but that they were very busy. Again, with great customer service.
