What owners reported
Source: NHTSA complaint databaseOwners of the 11 model years this bulletin names have filed 384 complaints with NHTSA since 2015. 77 of them name Electrical System — 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.
ICCU failed leaving me stranded on the side of the road (thankfully not on bridge). This was supposed to have been fixed under a recall the week prior by reprogramming the computer. Genesis has not changed the ICCU so even if/when repaired, it will most likely happen again. The Genesis of Wexford, PA dealer confirmed ICCU and fuse blown.

The driver seat module was defective, it was replaced & is still not working properly. It works sporadically. The navigation system freezes sporadically, the instrument display panel gives incorrect information. The Speed Limit Display indicated "34" when the heated seat feature was turned on, but the posted speed limit was 55.
2022 Genesis G80 · Electrical System · filed with NHTSA Jul 1, 2022 · ODI 11472023
My car was originally parked outside the garage. I started the vehicle using the key fob. I began to press the remote smart parking assist button to back the car into the garage but the button was not working correctly and would not move the car. At that point, I went into the car and reversed it manually into the garage.

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 SERVICE CAMPAIGN T47G a recall?
No. A service campaign 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 SERVICE CAMPAIGN T47G repair free?
A service campaign is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does SERVICE CAMPAIGN T47G cover?
The manufacturer filed it against 11 model years: 2024 Genesis G80, 2023 Genesis G80, 2022 Genesis G80, 2021 Genesis G80, 2024 Genesis GV70, 2023 Genesis GV70 and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
