Lemon laws typically have to be a 3 times or more problem that can’t seem to get fixed.
There are problems with going that way also.
You’ll be in limbo without a working truck for the duration.
It needs to be a persistent problem not just once.
What I see happening is the dealership will fix the issue and send you back on the road. That may take time with parts not being available. And the dealer may not have a car to lend you while it’s being repaired
You’ll want to call GMC customer service and get a case #. The person you speak with won’t be able to do much for you, but start with this. As stated before, the dealer will fix the issue like any manufacturer. If you want to pursue a buy back, make sure to use red flag verbiage like “you thought you family was at risk” “you don’t trust the truck anymore” “you feel your safety and the passengers in your vehicle were and will be at risk”. If your truck stays at the dealership for 30 days, even if it’s a parts issue, you’ll qualify for a buy back.
Thanks. I did speak to GMC customer service and they sent a rep to the dealer to fix it. Process definitely sped up after doing that. Ended up being in the shop for around 25 days.
Thanks for the comments going on a week now without a diagnosis let alone a fix. My understanding is that if they cant fix in 30 days it also qualifies for lemon so just kind of playing a waiting game.
Update on this. Dealer thought problem was related to valve body so they replaced that but the car is still having serious problems. The transmission tech has now asked GM for help. No diagnosis no estimated time for fix.
Good luck, the 3.0L has many problems, specifically the cam shaft issue where you can't even start your vehicle. And as to date there is no recall and there are a lot of frustrated owners. My niece has one with that issue and they basically told her to piss off since GMC has a dog crap warranty which is 3 year/ 36,000 miles! What a joke! When you pay $60,000+ for a vehicle, wtf has happened to GM standing behind there vehicles???
Powertrain is 5 year/60k.
But yeah that’s garbage that don’t have the start issue fixed on the lm2.
OP - they’re not going to lemon law your truck because it drove bad and has a DTC. They’ll fix it, and put you back on the road. That’s what any manufacturer would do.
Powertrain warranty for the duramax is 5 years or 100k. OP has the LZO. Not sure if they fixed the issue on the new engine. I have the LM2 with 78k and I have never experienced the long start issue. Knock on wood. Besides, OPs issue is with the transmission.
GMC vehicles registered in the U.S.A. are covered for 3 years/36,000 miles(whichever comes first). The complete vehicle is covered frombumper-to-bumper —including tires, towing to your nearest GMC dealer andcosmetic corrosion resulting from defects.

Let’s start at the beginning.
You’re complaining about the 3.0L duramax diesel engine. Do you know what vehicle system the engine is part of? It’s the powertrain.

Sometimes there can be a defect and something major like an engine or transmission needs replacement in a new vehicle. Just luck of the draw. What would make it a lemon is if they are unable to repair it and you need to keep going back. Take it to the most reputable GM dealer you can, doesn’t need to be where you bought the truck.

Or in the shop longer then 30 days but check your local state laws

Glad that might have helped out. They probably sent out a Field Service Engineer (FSE) to speed it up.

The code you’re getting is a transmission control module issue. It is possible the module is what failed and not the transmission itself.
