My '17 Chevy Malibu is a lemon, what to do?

Hi all, 1st post here.

I have leased a '17 Malibu which, despite being smitten by the car at first
sight, under 7k ODO the GPS and driver assist radar stuff became
unreliable. The GPS, GPS screen, lane keep assist and adaptive cruise only
work when they feel like it. I drive almost like an old woman, weaving around
potholes and such, and one of the front low-profile (Continental 18") tires
developed a bubble. Also, even at 10k ODO the CVT transmission jolts while
searching for gears upon accel/decel. That's crazy issues for a new-ish car.
It's my first Chevy (1st GM vehicle too) and I have been nothing but
disappointed with the quality of service to take care of the issue thus far. The
dealerships (managers) basically blame me for the problem, and take no
accountability whatsoever. They replaced the radar module thing, and it still
has the same problems as originally.

This is more of a rant than anything, but I have considered ending my lease
prematurely due to the reliability issues (when I was actually thinking of
buying the car post-lease). If the radar, tranny and tires give issues this
soon, then it's safe to say there are other lingering mechanical or otherwise
issues that'll happen later on before they're supposed to.

I guess my question is: should I keep the car for the life of the lease? and
how does one go about that with Corporate in order to not be penalized by
it?

Another question would be: Could anyone recommend a buy-friendly car (or
suv...I live in the Northeast so they're a logical choice for weather reasons)
that won't give me the reliability problems for the long-haul?

TIA
