What owners reported
Source: NHTSA complaint databaseOwners of the 11 model years this bulletin names have filed 231 complaints with NHTSA since 2015. 5 of them name Power Train — 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.
I was driving the car and warning light “possible R gear fault-driving permitted” came on. While driving on a highway at 50 mph, gear shift started malfunctioning and oscillating between 2nd and 4th gears and I could not change the gears. I lost control of the car speed and it would drop to 25-30mph even if I stepped on the gas pedal.

The Macan engine cooling system is defective and dangerous. It is made with a plastic cooling lines that are poorly placed (and concealed) where they are subject to high heat and pressure and therefore break suddenly.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche 39/26 a recall?
No. A warranty extension 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 39/26 repair free?
A warranty extension 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 39/26 cover?
The manufacturer filed it against 11 model years: 2026 Porsche Macan, 2025 Porsche Macan, 2024 Porsche Macan, 2023 Porsche Macan, 2022 Porsche Macan, 2021 Porsche Macan and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
