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.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 211 complaints with NHTSA since 2015. 4 of them name 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.
I went on a test drive on this car and the car caught fire from the engine. I noticed after the fact that there was a recall on the vehicle for fuel pump malfunction that can cause fire. I've contacted Porsche about 15 times and they wont return my call at all. I also stared a case with them and they wont answer back.

The sunroof exploded outward as I was driving alone on the road. It was a loud bang and sounded like a gun shot. It scared me and I swerved. Luckily, I did not crash, and the sun visor was closed otherwise, the glass would have fell on me and possibly into my face and eyes - very dangerous!

A terrible drain design that has plugged drains emptying rain water into the car. The water from rear drain will fill into then Battery & Sub woofer compartment under under the spare. The drains are not easy to access for cleaning either.

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 WTB3 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 WTB3 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 WTB3 cover?
The manufacturer filed it against 8 model years: 2023 Porsche Macan, 2022 Porsche Macan, 2021 Porsche Macan, 2020 Porsche Macan, 2019 Porsche Macan, 2018 Porsche Macan and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
