  1. High pitched noise low speed - light acceleration or light braking

    I have the exact same noise. I’ve reported it to Porsche three different times, and every time they said they couldn’t hear anything abnormal. My 2020 Taycan 4S recently had both power electronics replaced under warranty because the car was randomly shutting down at highway speeds. Now that...
  2. 12V Battery Lifespan on a 2021 Taycan RWD

    12V batteries in Taycans should typically last well over 10 years. I have a 2020 Porsche Taycan 4S, and mine was recently replaced under warranty along with some other electronic components. I probably ended up with a faulty unit, because 6 years is only about half of the expected lifespan.
  3. WSS4 - High-Voltage Charger OTA Received...

    Yeah, honestly it feels a bit insulting from Porsche—especially deploying this update into a car that’s 6 years old in my case, and that have been charging at that rate for so long. Dropping the AC charging speed that much, now, when it doesn’t really impact battery health, comes across as...
  4. WSS4 - High-Voltage Charger OTA Received...

    I live in a high-rise with Tesla Destination Chargers (Universal Wall Connectors). Before I had the Taycan, I had a 2022 Model X Plaid, always charged at 10.5kW in the same charger. The Taycan did 9.5kW before and after the update wont go beyond 7.5kW
  5. WSS4 - High-Voltage Charger OTA Received...

    Has your AC charging speed been reduced? Mine won’t go above 7.5 kW, whereas before the update it reached 9.5 kW. It never hit 11 kW, even though my EVSE is capable, and with my old Tesla did.
  6. NHTSA Complaint - Loss of power while accelerating - turtle mode - March 31, 2026

    I had the same issue, definitely not funny. I was traveling around 60 mph with traffic close behind when the car suddenly started slowing down. I pressed the accelerator and got no response, and the car came to a complete stop in the middle of the interstate. I have owned 4 Teslas before and...
  7. [March 2026 Update] - Porsche's ONLY OTA update hobbles North American Taycans to max 9.6 kW charge rate…

    Hi all, new to the forum but not to EVs. After installing the March OTA on my 2020 Taycan 4S, my AC charging dropped from ~9.5 kW to ~7.4 kW (about a 31% decrease). I use Tesla Destination Chargers in my condo set for 11 kW/60A—while the Taycan never hit 11 kW, 9.5 kW was consistent and...
