This! It's always in the early morning and the late evening when the sun makes driving difficult. In my case, the sun seems to settle between my sun visor and rear-view mirror.
I'm looking forward to spring's arrival. It's always so dreary when all the leaves have fallen off the trees around here.
Was having this issue with the sun about a month ago, but not so much now. Sadly due to the fact that it ‘s generally dark when I leave for work & dark when I head back home
