Genesis bulletin 20-SS-004H
What it saysThis bulletin provides tire vibration service procedures, including how to optimize vehicle vibration performance. NHTSA’s full summary ↓
Genesis filed this with NHTSA as a service bulletin dated Nov 19, 2020, received Dec 8, 2020, about the wheels. It names 9 model years (2018–2020). 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 databaseOwners of the 9 model years this bulletin names have filed 238 complaints with NHTSA since 2015. 16 of them name Wheels, Tires — 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 vehicle has 11,000 miles on it. I just drove from Boston, MA to Scranton, PA on Thursday 6/24/21. There were no issues and I did not hit any pot holes. On Friday morning we started driving and 3-4 miles away going about 40 mph, we noticed a problem on the right front. I pulled over and we noticed the tire was flat.

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 Genesis 20-SS-004H 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 20-SS-004H 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 Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does 20-SS-004H cover?
The manufacturer filed it against 9 model years: 2020 Genesis G70, 2019 Genesis G70, 2020 Genesis G80, 2019 Genesis G80, 2018 Genesis G80, 2020 Genesis G90 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
