Riser Nissan Cannot Repair. Cannot Duplicate. Error happened at dealership when I went to pickup the van after nearly 5 weeks of service being done on it. Dealer could not duplicate for 5 weeks. Showed Counterman the issue and he made it do it over and over and I was advised take it home and bring it back next week and they would figure it out. Next time in for service I was told same thing. Cannot duplicate.
