Porsche bulletin No. 2531

What it saysInstructions on advanced technical information for the Surround View Static Calibration – Explanation of Debug Screen NHTSA’s full summary ↓

Porsche filed this with NHTSA as a service bulletin dated Nov 21, 2025, received Dec 5, 2025, about the visibility/wiper. It names 26 model years (2019–2026). 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 database

Owners of the 25 model years this bulletin names have filed 438 complaints with NHTSA since 2015. 9 of them name 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.

The drivers side wiper leaves a streak at drives eye level during most rain events. My dealer has replaced the wiper 3 times but this has not fixed the issue. My Dealer has verified this is happening and verified this happens on all Porsche Cayenne vehicles of this age and model.

2023 Porsche Cayenne · Visibility/Wiper · filed with NHTSA May 30, 2024 · ODI 11591516

I am filing a complaint regarding an ongoing and unresolved HVAC odor issue affecting my 2023 Porsche Cayenne S Platinum Edition. Since shortly after taking ownership, the vehicle has consistently produced a strong mildew/musty odor after sitting for several hours.

2022 Porsche Cayenne · Visibility/Wiper · filed with NHTSA May 27, 2026 · ODI 11740501

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 579.5

Is Porsche No. 2531 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. 2531 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. 2531 cover?

The manufacturer filed it against 26 model years: 2026 Porsche 911, 2025 Porsche 911, 2024 Porsche 911, 2023 Porsche 911, 2022 Porsche 911, 2021 Porsche 911 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
