What owners reported
Source: NHTSA complaint databaseOwners of the 7 model years this bulletin names have filed 279 complaints with NHTSA since 2015. 225 of them name Electrical System, Power Train, Fuel/Propulsion System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
The car is an electric car. I was driving on the highway and the car shut down completely leaving me without power steering, engine control error, electrical system error. I had to glide to the shoulder of the highway. Luckily traffic was light enough that I was able to get over on the highway and avoid getting hit by other vehicles.
2023 Porsche Taycan · Electrical System · filed with NHTSA Oct 18, 2026 · ODI 11771935
My complaint is that the car will not move. I get in the car to drive and the car displays the following message, “ Electrical System Error. Stop vehicle in a safe place.” This has happened on numerous occasions(at least 7) since I received the car on February 10, 2021. Mind you I work from home so I don’t drive it but once a week.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche WTL2 a recall?
No. A service campaign is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the WTL2 repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does WTL2 cover?
The manufacturer filed it against 7 model years: 2026 Porsche Taycan, 2025 Porsche Taycan, 2024 Porsche Taycan, 2023 Porsche Taycan, 2022 Porsche Taycan, 2021 Porsche Taycan and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
