When the forward collision warning activates, the braking pedal loses its effectiveness and causes the car to brake much more slowly than it should, which actually increases the chance of a collision occurring. This has happened multiple times to me in the past few weeks. It is a very dangerous problem.

While charging my 2023 Porsche Taycan 4S at an Electrify America station, white smoke began emitting from the front wheel/charging port area. The vehicle also produced a burning odor inside the cabin. I immediately stopped charging and unplugged the vehicle. The smoke ceased within approximately 1–2 minutes. The vehicle was towed to an authorized Porsche dealership. Initial explanation from the dealer was steam from when radiators heats-up, which is inconsistent with the conditions and prior use history. Upon further inspection, the dealership identified battery-related issues. Ultimately, I was told that 8 out of 10 battery cells were replaced. The vehicle was out of service for approximately one month. The dealership stated that the battery cell issue was not related to the smoke event, which is concerning given the timing and severity of the incident. This vehicle had previously been subject to a battery-related recall addressed via software update only. I believe there is also ongoing litigation related to battery safety in this model. Given the smoke event, burning odor, and significant battery component replacement, I am concerned about the safety of this vehicle, particularly risk of thermal event or fire during charging. Note, I have a video of the smoke when car was charging, not able to upload video here
