Porsche Taycan

My 2020 Porsche Taycan 4S (VIN [XXX]) has a recurring, dangerous brake failure that remains unresolved after multiple dealer repair attempts. At low speed, the automatic emergency braking system activates on its own and begins decelerating the car. As the car slows to roughly 5 mph, the brake pedal drops, braking pressure disappears, and the vehicle keeps rolling forward. Pressing the pedal as hard as I physically can does not bring the car to a stop. On more than 5 occasions I have had to…

Component/system: High-voltage (HV) battery system and power electronics. 2020 Porsche Taycan Turbo, VIN [XXX] . Vehicle available for inspection. Safety risk: Since January 2025, the vehicle has repeatedly displayed a pull over and park safely emergency warning and shut off unexpectedly while driving at highway and surface road speeds. Sudden loss of propulsion at speed created serious collision risk. Dealer-confirmed: Porsche Woodland Hills documented (July 2025): vehicle just shut off on…

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.

The tungsten carbide coating on the PSCB (Porsche Surface Coated Brake) rotors has failed at 44,000 miles. This is not normal wear. The Taycan’s regenerative braking system handles the substantial majority of deceleration under normal driving conditions, meaning the mechanical brakes on this vehicle have seen a fraction of the use they would on a comparable internal combustion vehicle at the same mileage. Coating failure under these conditions is consistent with a material or manufacturing…

While driving my 2023 Porsche Taycan under normal conditions, the plastic underbody protection panel on the bottom of the vehicle came loose and detached. The metal underneath the plastic panel is now visibly bent. I did NOT hit any object. There was NO impact. I did NOT hear or feel anything during driving. There were no warning lights, alarms, or messages on the dashboard. The first indication of any problem was discovering the detached plastic and bent metal after the fact. This is a…

The vehicle has now gone into Turtle Mode three times in the last month. Twice to dealership without fixing issue. Turtle mode renders the car undriveable. There is no propulsion, car won’t go over 20 mph

The mapping system is out of date and tried to route me to an offramp that doesn't exist. I did some research and found the offramp changed over 4 years ago, roughly when the car was built. I took the car to my local dealership to get the maps updated and Porsche claims I have the latest map. I think this is a dangerous situation if someone tried to drift off the road in bad weather (for example) where an offramp doesn't exist. Their newer cars show the correct mapping. Porsche should be…

While driving in traffic on a busy highway, I heard a loud clunk from the rear of the car and it instantly decelerated from 70+ miles per hour to 22 miles per hour, where it stayed and would not go faster. I had to get across 3 lanes of traffic to exit. Thereafter, the car would not move and had to be put on a flatbed to get to the Porsche dealer. Note that for 2 years prior the transmission had emitted a whine while in first gear. The dealership (Porsche Austin) said it was normal, but it…

There are .recalls.on the Vehicle I had been unaware of and I dropped off my vehicle for exterior buffing while person Buffing vehicle he heard a loud explosion and when he looked the vehicle was up in flames the vehicle burned. There was a Risk of someone getting Harm , Killed and Damages to other vehicles on the property in same lot vehicle was being buffed . Police and Fireman were dispatch to location.

I am reporting a safety issue with my Porsche Taycan. On two separate occasions within the past month, the vehicle has experienced a sudden and complete loss of power while I was accelerating hard on the highway. In both instances, the vehicle immediately entered “turtle mode,” severely limiting performance to the point where there was effectively no power available to maintain speed or safely maneuver with traffic. The only way to restore normal operation was to fully stop the vehicle, turn it…
