What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 2 complaints with NHTSA since 2015. 1 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.
The car suffered a critical electrical failure which resulted in the car abruptly losing power when driving at a speed of about 30 mph. The speed at which the car became unresponsive was so rapid that the car could not even be maneuvered from the middle lane into the right most lane for safety.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No.60-25 a recall?
No. A service bulletin 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 No.60-25 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Porsche warranty extension on file lists the ones Porsche has filed.
Which vehicles does No.60-25 cover?
The manufacturer filed it against 2 model years: 2026 Porsche Taycan, 2025 Porsche Taycan. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
