So I have 5000 miles on my Titan and have this DEF error message. Nissan dealer I talked with reports he has 4 on lot with same issue. He was honest and told me that they have changed parts and had them come right back. He thinks it might be a software issue. He reports Nissan is working on it but don't have a solid fix.
Had a 298 miles trip home, it came on then went away and stayed off for 60 miles. Drove for another 40 then the light came on. Did you hear anything else about this issue. I just had the tran updated on friday
No I haven't except that they have had several in for same issue. I don't think they really know how to fix it by what tech was saying. He thinks it is more of a software issue but is going to try changing a sensor. Hopefully have more info after tomorrow.
