Source: NHTSA complaint databaseOwners of the 5 model years this bulletin names have filed 103 complaints with NHTSA since 2015. 16 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.

2019 Porsche Cayenne · Engine · filed with NHTSA Nov 9, 2025 · ODI 11698394
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.

This engine EA839 is the same engine installed in Audi’s and which has a massive engine replacement going on now. It seems that the above engine has what is called piston slap or rocker arm failure which requires a complete engine replacement.

Common questions
Source: NHTSA, 49 CFR 579.5Is Porsche No. 2412.2 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. 2412.2 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. 2412.2 cover?
The manufacturer filed it against 6 model years: 2023 Porsche Cayenne, 2022 Porsche Cayenne, 2021 Porsche Cayenne, 2020 Porsche Cayenne, 2019 Porsche Cayenne, 2020 Porsche Redundant Cayenne E-Hybrid. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
