What owners reported
Source: NHTSA complaint databaseOwners of the 49 model years this bulletin names have filed 553 complaints with NHTSA since 2015. 6 of them name Steering — 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.
This is a 2025 Porsche 911. The car came equipped with "Land Keep Assist" also referred to as "LKA". In operation it is at times terrible, and at other times genuinely frightening. The system, without warning, intervenes to change the direction of the vehicle by applying steering input. It is very, very, inaccurate and unreliable.

Steering Gear. It has been replaced and is not available to inspect. I was unable to turn the steering wheel and had an auto accident as a result. The dealer inspected the vehicle and replaced the steering gear under warranty. It is probable that the defective gear was sent by the dealer to the manufacturer to inspect.
2024 Porsche Macan · Steering · filed with NHTSA Mar 1, 2026 · ODI 11721240
On nine (9) separate occasions the vehicle which is equipped with Lane Keep Assist (LKA) automatically and without operator intervention will engage LKA which causes abrupt and at times uncontrolled steering action which totally surprises the operator. This occurs at random times approximately 40 to 50 miles per hour.

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 87/20 4812 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 87/20 4812 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 87/20 4812 cover?
The manufacturer filed it against 71 model years: 2025 Porsche 718, 2024 Porsche 718, 2023 Porsche 718, 2022 Porsche 718, 2021 Porsche 718, 2020 Porsche 718 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
