My 2018 XD SV 4x4 has only 22,000 miles yet spent 2 of the last 3 months in the shop with repeated electrical problems the dealer has been unable to solve. Apparently there was a leak around the windshield which ran behind the dash and under the carpet creating electrical havoc. First they found and "fixed" the leak and they replaced 2 wiring harnesses which corrected the trailer light connections. A week later the check engine and traction control lights started coming on. After several shop stays they ultimately replaced the accelerator. The next day the lights return with the addition of the information screen jumping to settings and freezing. The dealer opened a case with Nissan to address the issues. Two weeks ago they said another wiring harness would solve the problem. Now I still have no truck, and no support from Nissan. They denied a loaner and said they would make the truck operable but they didn't say when. What suggestions can anyone offer for dealing with Nissan's lack of actions in repairing or replacing my truck. Help.
