What it saysInstructions on advanced technical information for all models - Updated Primer Substance and Application Guidelines For Glass Installation/ Windshield and Glass Roof NHTSA’s full summary ↓
Porsche filed this with NHTSA as a service bulletin dated May 29, 2025, received Jun 2, 2025, about the structure. It names 103 model years (2016–2026). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 64 model years this bulletin names have filed 802 complaints with NHTSA since 2015. 27 of them name Visibility/Wiper, Structure — 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 rear window seal is severely breaking apart, severely cracked and others are melting. This may affect condensation inside the vehicle and potentially be a safety hazard. Several reports on this problem can be seen at porsche forums. I believe this is a manufacturing defect and is a potential safety hazard on many porsche vehicles
2017 Porsche 911 · Visibility/Wiper · filed with NHTSA Dec 17, 2024 · ODI 11631125
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.
2024 Porsche Macan · Visibility/Wiper · filed with NHTSA Oct 28, 2025 · ODI 11696217
I have almost collided in several instances due to the rear backup camera. It is almost useless after Porsche authorized dealer repair. It is now a defective back up camera. Dealer said when they repaired rear of my vehicle they did a software update and the rear camera update caused the visibility to dramatically decrease.
2016 Porsche Panamera · Visibility/Wiper · filed with NHTSA Sep 30, 2019 · ODI 11265215
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. 2514 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. 2514 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. 2514 cover?
The manufacturer filed it against 103 model years: 2025 Porsche 718, 2024 Porsche 718, 2023 Porsche 718, 2022 Porsche 718, 2021 Porsche 718, 2020 Porsche 718 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
