Well good..the first thing you can do as an adult is learn to respect your elders.
I don’t know what dealer you are taking your vehicle to, but obviously it isn’t the one I work at.
The dealer I work at doesn’t deny anything, we try to duplicate your concern and fix it right the first time and the fact that I have seen my service manager extend warranty coverage’s on vehicles way past the warranty period to keep customers happy never ceases to amaze me.
GM has to approve the warranty coverage extension and some dealers do have the ability to pre approve that extension.
What do you think happens when a dealer approves a warranty extension and GM denies it? The dealer eats the cost.
As far as your incident with your vehicle rolling on the parking brake, was it parked with the trans in gear (1st or reverse) like it states in your owners manual?
Is the parking brake a crap design?, I’ll say this, it wasn’t one of GMs shining moments, but on the other hand, I have this setup in my truck and it holds just fine.
And once again don’t me give that “i was professionally trained as a mechanic for four yrs when i was young” deal..I hear that all the time. Were you professionally trained or were you one of those guys who thought they knew enough about cars to make a living at it only to find the cold hard truth?
It is obvious you weren’t good enough to make a living at it or did the high tech changes on the cars scare you into another profession?
You think GM cars are garbage..well that is your opinion and you are entitled to it. And if using the internet to complain about it makes you happy..type on. I’m sure you will find some company out there.
I can tell you that with my well over 20 years in GM dealers that the quality of the GM vehicle is light years above what it was in the 80’s.
Plus the technology used in today’s GM is light years beyond what the other automakers have out there.
The problem with the advanced technology that GM is using is that many people in the sales and service end (dealers) have not kept up with the changes and are getting further and further behind.
This equates to the definite possibility that many customers will find it harder to find qualified TECHNICIANS to diagnose and repair their vehicle properly.
This leads to customer dissatisfaction…..what this means to me (the fully trained, certified and experienced TECHNICIAN) is more available work and the fact that more and more dealers will be seeking others and myself in my position out to meet the needs of their customers.

Like someone else said, if you don’t like your vehicle buy something else..it’s a free market, and no one twisted your arm to buy what you did.
You will find that ALL automakers have problems and you will find that some are less generous with their warranty coverage’s than GM.
Good luck
