I own a 2020 impala lt, bought in December last year. I haven't put many miles on it do to the pandemic going on as well as knee problem as well. Earlier this year i noticed a spot of green fluid in the garage about the size of a quarter. I made an appointment at the dealer. The next day got it back with the explanation it's a dye they use in the ac. They also said it was over filled at the factory, they adjusted it tested and said it was ok. Last week I noticed it again. Had anybody else had this happen, if so what was the outcome? I love this Impala andwant to care for it as much as I did for 2009 i had.
