... or is it just in my head?
We had the final recall update performed a few weeks ago. Since, I know how to limit charging to 90% on my own, we never bothered with the interim fix. After the final recall-update/fix, we think we are having substanitially less regenerative braking when in "L" mode. Before the update, I felt that the car was akin to driving a manual shift car in which you down-shift for compression braking when slowing down, e.g., to go around a corner or to descend a hill. Now, not so much.
Case in point: We live in a hilly neighborhood. My wife commented on how on one particular hill, she never had to apply the brake before. Now she had to ride the brake. She even double checked that she was in "L" and not "D" because to her, it felt like the latter.
We never charge beyond 90%, in part because of the many hills in the neighborhood.
This is on a 2019.
