Brake Disc Pads problems of the 2018 Chevrolet Equinox

I purchased this vehicle I June 28th of 2018. I have had to take it into the shop at least three times with complaints of squeaking from brakes mirror alert problems trunk sticking and the suspension has gotten worse since I first started driving it I'm noticing it. Every time I complain they tell me nothing is wrong except for at the beginning of my lease it had to be taken in for repairs. I was told that the brakes squeaking is not a safety issue and it was recommend to change my brake pads and in the same conversation was told that my brakes were fine. I spoke to the manager at balise chevy because I felt like this veichele was a lemon. I asked if there was anything they could do because I did not have time to keep taking this brand new veichele because it was a lease so they did nothing. Balise chevy in warwick should have notes of complaints. I also took the vehicle to hurd auto mall in johnston. There was a slow leak in one of my tires and balise could not find the leak so I was told if it happens again they would submerge the tire and check that way. They sent me home the tire continued to leak air my last oil change was done at hurd automall in johnston where they did an oil change found the tire leak no problem and fixed it.
