Brake Disc Pads problems of the 2016 Nissan Versa

Bought the 2016 vehicle October 15, 2015. Right away noticed a problem with the automatic gear shift not moving smoothly from gear to gear. The brakes groaning/whining and the emergency brake loosening. Car drifting/pulling right on highways and left on streets. Rattling from under car carriage. Popping and squeaking on right front passenger door. The a/c straining and not cooling car cabin as it should and the a/c interior switch not engaging or staying engaged when pushed. Thumping/clicking sound heard when braking. After numerous complaints made the dealership verified all of my complaints but not in a timely manner. First complaint was acknowledged on October 28, 2015 but claimed there wasn't any abnormalities found. On December 8, 2015, March 16, 2016, April 22, 2016, August 17, 2016 and August 23, 2016 repairs were repeatedly made consisting of replacing gear shift knob, entire gear shift assembly, sanding rotors, replacing brake pads, replacing entire brake assembly and tightening emergency brake. But as to date problems still exist. On February 9, 2016 repair to the suspension and steering. On April 5, 2016 repair to lower rear exhaust shield remounted. On may 31, 2016 door check straps re-secured. On June 23, 2016 faulty bmc switch replaced but problem with a/c still not resolved and a second problem has arisen. A/c turns on when defroster is engaged. On September 23, 2016 problem with both front inner cv joints and axles acknowledged but part on back order. Repairs made on October 27, 2016 in another state. Problem not resolved. Sound still heard when driving over speed bumps, cracks or slight bumps on streets or highways.
