2020 Porsche Taycan · Service Brakes · filed with NHTSA Oct 1, 2024 · ODI 11617476
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
2023 Porsche Taycan · Service Brakes · filed with NHTSA May 11, 2026 · ODI 11736999
There was a different amount of pressure needed to apply to the break when at lower speeds vs higher speeds. At lower speeds there was less responsiveness to the breaks and more pressure was required to stop the car. We brought the car to the dealer and dealer reported the car was fine.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche ARB0 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 ARB0 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 ARB0 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.
