Oil Consumption

I purchased a 2013 Chevy Eqinox last year in June..
August all hell broke loose.. I took it back to the
dealer. The rep in the service department calls me
and says this engine is crap. I say to him I
purchased it from there.. He says I'll call you back.
Calls me and say oh it just needed an oil change.
Ok got that done.. Took it back 2 months later
same thing.. 2 months later same thing. The last
time I had to have it towed to them cause it just
shut down.. No warning. Then they tell me oil
consumption It's been there for a month I'm so
pissed cause the warranty company denied my
claim.. I just wanna walk away from it but don't
want this to mess up my credit that I worked very
hard to get it to where I am..smh but from the
looks of it these vehicles are crap
