Wiring Problems of Infiniti M35

On March 9th, 2015 my 2006 Infiniti M35 stalled while I was driving it and wouldn't start again. I checked the fuses and battery and couldn't find any issues so I had it towed to the local Infiniti dealer. Initially the dealer told me that the ecm (brain) needed to be replaced and, after a fair amount of pressure from me to stand behind their product, the Nissan factory agreed to cover the ecm replacement (~$2200). On April 9th, 2015 they informed me my car was "fixed and ready" however when driving home it stalled on the freeway (while going ~70mph with my kids in the car with me) and again, it wouldn't start. I had it towed back to the dealer and paid for an advanced diagnostic ($420) at which time they discovered "melted and shorting" wires between the power distribution unit (pdu) and the fuse box. . . On April 22nd, 2015 they replaced these wires (they never actually diagnosed the cause of the melted shorting wires) and they again told me my car was "fixed and ready". . . Yet again, while driving home the car stalled on the freeway and wouldn't start. I had it towed back to the dealer again and they called in an advanced factory technician who determined that the main wiring harness and another wiring harness needed to be replaced and they're quoting me an outrageous amount for the repair ($8400). The car currently shows a ~$10. 5k value on kelley blue book. . .

Recall work done on 01/08/2014 at internation Infiniti waukesha, WI dealership. 01/09/14 faint burning smell noticed, again on 01/11/2014 faint burning smell notcied. Then on 01/14/2014 lots of dashlights like abs, cruise control, vdc, slip, brake lights all flashing on/off while speedometer flipping up & down from speed car going to zero, nothing in between. Brought car back to dealership 01/15/2014 with appt made on 01/14/2014 and they looked at car for 4 hours and could not definitely say exactly what was wrong but said that I should have wiring harness replaced at cost of $2200. 00, without proof that it was definitely the problem & that they didn't cause this problem since I had problems with the car the very next day after they worked on it.

: the contact stated the vehicle lost power and stalled at highway speeds of 55 mph without warning on two occasions. After both incidents the vehicle was driven away from the sight slowly and taken to a service dealer. After the first incident the dealership replaced the throttle body. When the vehicle was returned to the dealer after the second occurrence, the dealer was able to duplicate the problem. The dealer replaced the wiring harness. Updated 06/16/06.
