General Motors review: 2015 yukon denali

I bought my yukon with 17k miles on it several years ago. From the time I drove it home, it had issues with the transmission. I took it in to be looked at and they said it was an issue with the fluid. Then it was an issue all around. Now, after I have dealt with it for several years under close care and observation, it is now causing so many issues that it is needing replaced. I was quoted almost 7k for it, and the insane part was the design was flawed. My engine should not be doing this, and the fact that GM offers no resolution on a faulty or poorly designed engine component, the company should stand behind their designs and offer something for this. It is upsetting that when the vehicle is being serviced that it is known that these have issues and when taken in, there isn't a recall on the faulty design. I cannot check my transmission fluid without taking it to be serviced. I hope GMC will stand by their products. I have always loved my Yukon, but am very certain that I can find something else similar that causes less issues that this. I don't know how I could have a remedy for this, but I'm hoping for something.
