I feel this. I had always owned Fords, bought a '23 Sierra 3500 Denali Duramax 7 weeks ago. 5 weeks ago I got the P0700/P0747, while 3-states away. Truck is still down at the dealership. Had received one valve body already, but it "failed to calibrate" and the truck would not shift out of first gear. Still waiting on another to arrive. Nothing like buying a truck and it then being in the shop longer than you've had it in your possession, since purchase. Have thousands in rental receipts I'm waiting on GM to reimburse me for, but need to "wait for my repairs to complete", which again we have no ETA for since the parts are on back order. GM has lost any future business from me.

I was also told I would be fully reimbursed for rentals, as I wouldn't be provided a loaner since I was 3-states from home. It's been 4-weeks since my truck broke down, and am working on getting my first rental receipt reimbursed, would only reimburse me for $308 of a $835- bill. The rental was a one-way rental, since I was stranded from home, hence why it was even more expensive (did a week as weekly rate was cheaper than just driving it back for the day). Apparently GM has requirements for rental reimbursement, must be a GM vehicle, and they'll only reimburse up to $44/day, etc. How is $44/day supposed to cover anything close to a 3500? My first rental was not a GM vehicle, as I was at the mercy of whatever was available that day. I notified GM, they said they would make note of this in the case, and should be able to provide a full refund due to the delay in travel -- NOPE. I don't know about your state, but in MI, Lemon Law can be applicable on used vehicles, if still within their OEM warranties. I will be contacting a Lemon Law attorney myself this week as I'm out over $27k in cash the last 6 weeks between down payment, rentals, travel, etc. and have only had the truck in my possession for 2 weeks. And I can not be provided any sort of ETA on repairs, as the valve bodies are still on backorder and transmissions themselves are now on national back order, as of 5/15. I feel bad for others not aware of this issue going out and still purchasing these trucks.

Update of events since 4/23. Dealer stated a transmission replacement was approved under warranty since their was no ETA on the availability of the new VB PN: 24066238. They would wait until 5/2 to attempt acquiring a valve body, if not successful, they were to order the transmission on 5/2. 5/2: No valve body showed up 5/5: Transmission replacement ordered 5/8: Notified that on 5/6 it was discovered the transmission was now on backorder. However, on 5/6 a valve body showed up, was to now be installed and have the truck ready for pickup by 5/14 5/13: Notified that on 5/10 the valve body was installed, failed to program. Attempted to reprogram on 5/12, still failed. Manager directed to test drive truck and see if operational, truck would not shift out of first gear. I have a trip planned to travel across 3 states tomorrow in which I was also planning to pick the truck back up. No longer possible. Also currently have over $2,200- in rental car debt that GM is arguing over refunding fully. If they do not make this right, I can confidently say they've lost any future business from me. I hope I'm not the only one that feels this way.

Frustrated to say I'm now a part of the club as well. Let me preface this by saying I've owned multiple Ford's and drove hundreds of thousands of miles with never being stranded on the side of the road (call it luck, whatever). My truck was recently totaled and I decided to give GMC a go. Purchased a used 2023 Sierra 3500HD Denali L5P with ~33k miles, just 2 weeks ago (absolutely loved the truck so far). Over Easter weekend I traveled 3 states away to visit family, planning to tow a trailer back to my home state. The night before Easter I was topping the truck off with fuel, getting back onto the highway, and as soon as the truck went to shift above 6th gear, limp mode was activated, P0747/P0700 present. Obviously the dealerships are closed on Easter, I dropped the truck at a local dealership Monday morning (4/21). They complete their diagnosis and confirm the Valve Body needs to be replaced. Surprise, new valve body is STILL on back-order, with NO ETA for the new part to be available. Dealership would not provide me with a loaner vehicle as I would have needed to drive it three states away. Understandable, I'll just work with GM when I get back home to get a loaner from a local dealer, right? Rental agency had no trucks available last minute that could tow, having to leave my trailer 3 states away as well. I've since returned home, (had to cover rental cost to get home) and the local dealership's won't provide me with a loaner as they're not the ones doing the repair on the truck. I've reached out to GM support, to which they offered a $44/day stipend for a rental vehicle. HOW am I supposed to replace a truck via rental for $44/day? And then I'm supposed to cover the charge for the rental until the truck is repaired, which we DON'T even have an ETA for!? Aside from the replacement/loaner vehicle situation in the meantime, HOW is this part still on back order? I have multiple trips planned over the next month that require a tow vehicle, and no timeline when I will be able to get my truck back. So now I'm covering the charge for a rental and about to start making payments on a $70k+ truck, that's THREE STATES AWAY. This is just unacceptable from a major OEM, and I'd be lying if I said I didn't regret going away from Ford.
