Bought a brand new 2024 3500 Denali

Bought a brand new 2024 3500 Denali, the truck has been breaking down every 3 months since. The most recent breakdowns were in Texas and Colorado. Truck broke down in the Dallas area, transmission completely failed, could not get to Vegas with my haul. Went to 5 dealerships in the area, some were closed on Saturday, some were open with one guy behind the service desk doing nothing. I was told that no technicians were on site and that they will re open only Tuesday. No dealership was able to provide me a courtesy vehicle as well. I still haven got any refund and compensation for that major break down (travel expenses, heavy truck rentals…) I picked up the truck in Texas, the very next day the transmission was acting out again but I was able to make it to Las Vegas. Stopped by my dealership regarding the issue, was told that the truck needed to be driven for a month so the transmission could synchronized with some modules and sensors. After a month I went to Colorado, transmission failed again and the top of it, there is a also a big leak underneath the engine, the master cylinder leaks as well…the truck is just falling apart. Took the truck to the nearest dealership in Denver, was told they will look at it in 7 days….then a few days later got a phone call from them to tell me that they won’t look at the truck for weekS… unbelievable!I called the GMC customer service and got the truck towed to another dealership that was supposed to look at the truck on Monday…. then same BS, got a phone call about three weeks ago to letting me know that they will only look at the truck on the 8th….Haven’t heard from the dealer since so I called today to check in on the repairs…. The Dealership can’t find my truck !!! They never had it ! The truck is nowhere to be found, called multiple dealerships, GMC towing assistance, GMC customer service… nobody has answers and they just don’t care.I am still trying to get compensation for the breakdown in Texas, trying to get compensation for the breakdown in Colorado, trying to get my truck repurchased and now trying to locate my truck… it’s just been a nightmare.My case manager Allie is incompetent, she sounds like she is 12 and just apologized on the phone in repeat mode, I think she is AI !GMC is supposed to be the top of the top…. Well it’s not !It’s time to lawyer up
