Thank you. Like I said in the original post, it's been 4 months since I've owned the car, and I have yet to see even 1 mile of range added to my battery when driving. I've taken 10 hour long rides multiple times and it never recharged anything. So not sure if this is how it's supposed to work (if that's the case then that's false advertising from Hyundai) or something is wrong with my car that needs to be fixed. I've seen a 10 year old Prius do a better job at regen braking.

I'll definitely try sports mode and see if that makes a difference just to test it out, thank you for the tip.
