Read by machine from the document NHTSA serves (7 pages), read Sep 30, 2026. A part number is shown only where it matches Porsche’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

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 23 model years this bulletin names have filed 283 complaints with NHTSA since 2015. 45 of them name Engine — 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.

On my 2021 Porsche Cayenne Base, which is equipped with the 3.0L V6 EA839 engine, I brought the vehicle to the dealership for a recall service. During inspection, the dealership found a leaking water pump and quoted $8,500 for repairs. There were no visible signs of a coolant leak on the ground, indicating an internal seal failure.

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. 37-23 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. 37-23 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. 37-23 cover?
The manufacturer filed it against 37 model years: 2024 Porsche 718, 2023 Porsche 718, 2022 Porsche 718, 2021 Porsche 718, 2024 Porsche 911, 2023 Porsche 911 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
