Porsche bulletin No. 93-25

What it saysTechnical information for Various Yellow Warning Messages in the Instrument Cluster and Fault Memory Entry "P057200" in the DME Control Unit NHTSA’s full summary ↓

Porsche filed this with NHTSA as a service bulletin dated Dec 8, 2025, received Jan 6, 2026, about the electrical system. It names 2 model years (2024–2025). 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 2 model years this bulletin names have filed 11 complaints with NHTSA since 2015. 2 of them name Electrical System — 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 rotary volume control knob on the center console of my 2024 Porsche Cayenne Coupe detached during normal, routine interior cleaning while the vehicle was stationary. The knob lifted off the control shaft with minimal contact from a standard handheld vacuum nozzle.

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. 93-25 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. 93-25 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. 93-25 cover?

The manufacturer filed it against 2 model years: 2025 Porsche Cayenne, 2024 Porsche Cayenne. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
