2025 Chevrolet Tahoe

My Vehicle has a 5,3 engine it now has 23000 miles. It goes to the dealership for all the oil changes. I check my dipstick before I took it in for service and warranty work for a third time first time at this dealership. But noticed there was no oil on the dipstick. So I went to auto zone and bought a new 3 gallon container and funnel. So they changed my oil and put it in and I got my vehicle back and I now bought a clear 2 gallon measuring bucket to see how much oil I had in it. I just videod my pour into the container and it is 3 quarts low. I was under the 7500-mile mark that gm requires you to change the oil. This is a new vehicle, and I shouldn't see this happening at all maybe 100000 miles but not 23000. I also just found out I have a one of a kind 2025 Tahoe with the new 2026 software that is completely messed up. The dealership wiped out critical engine data and no that is at zero when I picked it up. And the calculation for engine hours and idle is not the true numbers and it is corrupted. The other dealership didn't know my vehicle has the new data. So I can only assume they made a big mistake releasing this vehicle. So I also have a driver's seat that goes snap or clunk. Everything with GM has Bulletins. I didn't buy a 86000 dollar used piece of junk i bought a brand-new truck. And Gm will not let the dealership tear into the engine to find out what the noise is and the damage. I use a stethoscope and you can hear the lifters and rockers on the left bank, and the front makes strange noises and it has a hollow sound also. So sensor collision avoidance issues since the day I bought it. And with all the corrupt downloads from whatever software they used has destroyed my Tahoe along with the engine. I have video evidence also and the oil that just came out of my vehicle was gross dark and disgusting and smelled to high heaven. I need help

ON JUNE 2ND 2026, the air conditioning in my 2025 Chevrolet Tahoe failed without warning. The system began blowing warm air instead of cold air, making the vehicle uncomfortable to drive. At the same time, I noticed that both front ventilated (cooled) seats had also stopped working. Although the seat cooling indicator lights illuminated when activated, the seats did not produce any cooling. I called to schedule an appt and took the vehicle to the dealership for diagnosis and repair on june 4, 2026. The dealership determined that the A/C condenser had failed and replaced it. I was advised that the repair had been completed, and I picked up the vehicle believing the issue had been resolved. Shortly after the repair, it became apparent that the problems had not been fully corrected. While the air conditioning initially appeared to function, the ventilated seats continued to provide no cooling despite appearing to operate normally. This marked the beginning of an ongoing series of HVAC-related failures that ultimately required multiple return visits to the dealership.
