Battery Dead problems of the 2013 Infiniti JX35

Vehicle died while driving in parking lot and all interior lights began to strobe with an awd failure light. The vehicle would not restart and the front seats started moving. Vehicle battery died while vehicle was in tow and has been at dealership for almost 2 weeks. Previous problems (within days) include seat memory not pairing with key, key not working to unlock hatch.

From the first week of purchase many electrical problems mirrors don't return to drive passion, windows while driving go up and down at random then the auto up doesn't work for days then just starts working again dash light go dark gps and radio do not work when cold until after car starts to warm up then electrical slowly returns seat does not keep memory, luggage rack has been replaced 4 times driver side rack coming completely off, loud squealing noise coming from the fan had to be trailer back to dealer. Dealer said nothing was wrong, tie rod boot burst on drivers side, battery went dead had to be jump started dealer seems to have no answers just excuses or wants to blame me for the many problems.
