Hello everyone,
We've taken the time to review this thread, and we wanted to weigh in with some insight from our end. To clarify, regenerative braking may become inoperative regardless of battery temperature or charge. This is true in all of our hybrid and electric products. The system will automatically reduce the amount of energy flowing into the battery to prevent damage and promote a longer battery life. It is likely that what you hear is the engine spinning up to help slow the vehicle, similar to manually downshifting a traditional car to slow down. The reprogramming mentioned by gjm3 may also be of benefit to you.
We would be happy to see if this applies to your vehicle. To do so, please send us your VIN in a private message.
Best,
Lauren E.
