What owners reported
Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 23 complaints with NHTSA since 2015. 3 of them name Structure, Visibility/Wiper — 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 home in my 2024 Porsche Macan 4 EV, at about 65 miles per hour on a divided highway. I had my climate control set to 75 degrees on both the driver and passenger side of the vehicle. I believe that the air conditioning was set to off. I also had the drivers seat heated at the max setting. I was alone in my vehicle.

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 No. 34-26 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. 34-26 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. 34-26 cover?
The manufacturer filed it against 5 model years: 2026 Porsche 911, 2025 Porsche 911, 2026 Porsche Macan, 2025 Porsche Macan, 2024 Porsche Macan. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
