Porsche bulletin No. D733

What it saysParts information for parts withdrawal involving (PAD423051B) the Steering Gear with Track Rods. NHTSA’s full summary ↓

Porsche filed this with NHTSA as a service bulletin dated Aug 18, 2025, received Sep 8, 2025, about the steering. It names 96 model years (2016–2026). 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 67 model years this bulletin names have filed 806 complaints with NHTSA since 2015. 23 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.

2025 Porsche 911 · Steering · filed with NHTSA Sep 6, 2026 · ODI 11762474

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 579.5

Is Porsche No. D733 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. D733 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. D733 cover?

The manufacturer filed it against 96 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.
