HaThese two burn holes were on the rear passenger seat behind the drivers seat. This 2018 Nissan Murano was purchased a little over a year ago hand has heated seats both front and rear. I had smelled something smoldering a couple of weeks ago however thought the smell was coming from an outside source. I brought it to the dealer to have them access the damage and they are insisting that these burn marks have nothing to do with the rear seat heater. No one has, or ever did smoke in my car. I do not transport combustable items. I never open the sun room. Has anyone experienced this issue? Cost to replace the seat is $850.00 and at the present time I am working on a claim to have the seat replaced with the Nissan Consumers Complaint department. Does anyone have any idea why this would happen?
