I think I might be done with GM....

I know exactly how you feel here, I previously had a Toyota, it had multiple problems, then I moved to this truck and now I've had it in the shop twice for two different electrical switch issues. I'm on a 2 week trip halfway cross the US and back and I noticed some oil around the oil pan, that looks to also be seeping out somewhere up at the front of the engine skid plate, not dripping on the ground yet, but seeping. I just did an oil change yesterday and only got 5 Quarts out of the engine, but had to put 7 into it, I've only put 5k miles on this truck since I purchased it used two months ago... regret is setting in and I'm wondering if I should go look for a good solid pre-2020 model truck with just under 100k miles that would likely be more reliable.

Then add in that sometimes I feel a good solid hard shift mid way through the gears while accelerating and I am fully expecting the transmission to give out while towing my small 19ft camper.

The hard shifts are a faulty valve body. I’d recommend taking it in so they can diagnose the problem and get the part on order and let you keep driving until it arrives and then schedule the swap. The first valve body that showed up for mine was damaged and they had to wait on a replacement for the replacement…go figure. Lugging around a 28’ camper when 1st & 3rd went out on mine wasn’t exactly an experience I care to repeat.

Good luck!

I hate to say it but, Toyota replacing hundreds of thousands of engines, GM doing the same, Ford and GM using the same faulty valve body so both are having major failures, it's a mess for sure.

Yea its not like the others ( Ford Ram ) are free of these issues. They're all in the same boat.
I was talking to an employee at Suncoast transmission and he said the main issue with the valve body is inferior aluminum quality. The parts are plain wearing out/ breaking. It's no surprise, we ship all of our metal to China to be refined and buy it back with mixed in impurities. Work on a truck from the 70s / 80s and you'll see the difference in material.
