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

Driving on a major roadway with no traffic or obstacles in front of me the car went into emergency braking mode and the engine shut down. The dashboard warning said “Engine Control Issue, Park in a Safe Place”. I could not restart the car for about 15 minutes, then it finally restarted and acted normally. The danger was the car braked violently and stopped in the middle lane of a busy street and I was unable to restart or move the car for about 15 minutes.

Taycan’s cabin heater fails during winter months without warning. Car will send out “precondition unavailable” messages With heater not working car is unable to defrost front window. It becomes a serious hazard while driving and needing the window to stay clear. Dealership so far is replacing the high voltage heater component. But might happen again within a few months. No actual remedy besides replacing with the same part that destine t fail again

On December 24, 2023, my family and I were involved in a serious accident while driving our 2023 Porsche Taycan. I was making a left turn at approximately 10 mph when a 2009 Honda Fit, traveling in excess of 65 mph, crossed into oncoming traffic and struck the left side of my vehicle. The impact was concentrated on the area around the front door, fender, and left-side charge port, causing over $60,000 in damage and rendering the vehicle a total loss. Despite the severity of the impact, the side curtain airbags failed to deploy. This malfunction significantly compromised the safety of my family, leading to a 60% tear in my left rotator cuff, which required surgery. The failure of the airbags exposed both me and my family to a greater risk of serious injury or death. The body shop recommended by the dealer, as well as the dealership itself, have both acknowledged this issue. The body shop could not understand why the airbags did not deploy. The vehicle remains available for inspection upon request. Prior to the incident, there were no warning lamps, messages, or other symptoms indicating any potential problems with the vehicle’s safety systems. The failure of these critical components was only discovered as a result of this accident.

Car has a red warning light come on that says engine control error park vehicle in a safe place. This happened on the freeway 4 times took it in to Porsche they claimed they fixed it. When the light comes on you have to stop the car and restart it. You can not accelerate. After it was claimed to be fixed it happened again but this time applied braking intermediary aggressively. The car behind me stoped in time before hitting me but just barely. Its very unsafe.
