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?

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.

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 Helm, I had problems with my DPF 2 years in a row on long trips and one of those (last year) was a failure bad enough that we had to have our camper towed around in Colorado and leave the truck and camper for over a month. This year, our problem is gone after a flash to raise the DPF burn-off temperature.

 

With that being said, if you have lost faith in your particular truck...I totally understand. I was right there last year with my issue and my wife and I were concerned to say the least this year when we drove on two longer trips...but we had no issues.

 

Maybe you will be able to get them to cover you on an extended warranty but I've never asked about it. If I were in your shoes and thought I'd have the option to push for a buyback or get an extended warranty I'd try to push it. If nothing else, ride your truck until close to warranty is out or you have another issue (and lose all faith in it) and trade that sucker in hopes that you get rid of your lemon! :D

 

Hope this help! But ultimately the decision is yours.

@Richard Helm, one other thing to mention is that GM Assistance will usually help you out with some of the costs of having to rent a vehicle to replace yours that's in the shop. I know they really worked with us on our issues last year.

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.

My advice is to trade it in on a different truck.  I agree with the previous reply's but you seem pretty convinced its not going to make it.  Who needs that added stress.  Trade it and move on.

Buyback seems unlikely and the lemon law isn't going to cover this.

 

And I can answer the question of what happens when the warranty runs out because you already know that answer too. That means it's over, case closed, you are responsible all repairs at this point and it's been this way since basically forever when it comes to warranty work. Some things may have special coverage but highly unlikely anything will be done. My parents were around 100 days past the 5 year/60k warranty on a truck with only 50k on it, a failure of a part cost them $2,000 out of pocket because the warranty was up, kinda just the way it goes.

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.

GM will absolutely not buy it back without you pursuing the Lemon Law. Lemon law guidelines are pretty cut and dry for each state. I’d look that over and see if you qualify. They will not buy a three year old truck back if they don’t have to. And they currently don’t have to… speaking from experience. It’s also quite a long process. They are in no hurry either. Truck is still worth quite a bit of money. I’d likely just trade it or sell it outright

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.

reoprt it stolen, then set it on fire under an overpass in the ghetto 20 miles from your house...lol.

 

 

if you want it to function normally, call the guys at EFI live and pay them to remotely tune it and disable all emmission equiptment. then you'll be a happy camper

Used trucks are still bringing a premium especially one ton diesels. She’s be a goner if it was mine. Then I’d carefully research what I really needed in a truck as far as a diesel. Or if I needed a heavy duty.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
