NHTSA Complaint #11512590 — 2021 VOLKSWAGEN ID.4

My vehicle was in Travel Assist mode (i.e. Adaptive Cruise Control) traveling at around 65 MPH. A vehicle has cut into my lane and I felt that the car wouldn't slow quick enough to avoid a collision. I have applied breaks effectively taking the vehicle into my control and taking the vehicle off Travel Assist mode. When driver takes over by applying the breaks in this scenario, irrespective of how hard the breaks are applied, vehicle suddenly moves faster than expected for first few seconds. I had to apply the break harder than I would have applied if I was driving the car in manual mode to get the car to slow down.The expectation was that the vehicle slows down while applying the breaks. This would have caused a collision if I was not quick to react. There were no warning lights or messages on the dashboard prior to or during this incident. This could be a software issue which probably is conflicting between the breaks travel assist is applying and the breaking that the driver is applying. This has happened multiple time to me and on date mentioned on this my wife had same experience confirming that this is in deed an issue that needs some investigating into before it cause any accident(s).
