Consumer Description

When driving using adaptive cruise control and my car decelerating using the regenerative braking, applying the brakes turns off the regenerative braking leaving only the friction brakes to slow/stop the car. I have demonstrated this situation to a VW dealer technician, who has confirmed that another 2021 VW ID4 that was in the shop duplicated this behavior. I have experienced this behavior multiple times over the last year. Because one of the systems for decelerating the vehicle is not available during a potentially emergency situation, I believe this is a safety risk. No warning lights or messages are displayed when this occurs. This has not been reported to my insurance company or the police.
