Brake Disc Pads problems of the 2014 Dodge Avenger

I got my front breaks done with aftermarket brake pads and rotors weird grinding squealing sound the place told me it was my transmission probably. I took it to the dealer for a diagnostic, and they said it was after market parts causing the noise and recommended that I get factory parts put on the car. I went back to jiffy lube, the original people who placed the aftermarket parts on and when they replaced everythin with factory parts, the noise still occured. I took it back to Dodge, informing them that their diagnostic that was recommended was handled and the noise still occurs. They, came back with the same answer "your front brakes". How is it that you diagnose my car and tell me it's one thing, and when I get that one thing fixed, it's still the same issue? at this point, I am convinced it's not jiffy lube, but Dodge not doing proper diagnostics because I also complained about my car jumping when I break and it takes long to shift into gear. They didn't even diagnose that and when I complained, they said everything was fine with my transmission. I own a 2014 Dodge Avenger and I got it from folsom lake Dodge.

The contact owns a 2014 Dodge Avenger. While driving out of the driveway, the vehicle made a loud screeching noise that sounded as if something were loose and about to fall off from underneath the vehicle. The vehicle was taken to a local dealer where it was diagnosed that the brake pads were faulty. The brake pads were replaced, but the failure recurred. The contact also stated that the vehicle emitted hot air from the driver side underneath the dashboard. The hot air intensified while driving approximately 50 mph. The dealer stated that the hot air was normal. The manufacturer was not notified of the failures. The failure mileage was 12,000.
