2020 Ionic SEL hybrid with roughly 1500 miles.
Several times when driving and regen braking set at 1 or 2 I get a “ding” and a warning saying “regeneration conditions not met” and the regen turns off and will not turn back on.
Never happens in the AM, only in the afternoon coming home from work.
Has happened at 15, 74, 25 and 54 mph.
Battery is not full.
Any ideas?

Battery bank too hot? Also - the LiPo batteries are very sensitive to over-charging. With the warmer temp in the PM it may be the computer protecting the battery from an overcharge. The regen braking is just running the electric motor in reverse causing a load on the motor - that load is heat and has to be dissipated, your electric components include a separate cooling system with it's own coolant - might be the under hood temp is too hot for regen braking.
