2020 Genesis G80

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651. Kia recalls 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652 The purpose of this AQ is to evaluate the timeliness and scoping of Hyundai and Kia’s defect decision making and adherence with reporting requirements; and understand the varying defect descriptions and remedies between these recalls.

I am reporting a recurring transmission/drivetrain problem that I believe may warrant investigation for a potential safety defect. Beginning in approximately May 2026, my vehicle developed a pronounced hard bump/jerk and shudder during transmission operation. The problem initially occurred primarily in 3rd, 4th and 5th gears and became more noticeable after the vehicle warmed up. The condition was significant enough that I took the vehicle to Genesis of Columbia/Silver’s Hyundai for diagnosis. On June 1, 2026, at approximately 90,223 miles, the dealer documented that they had “verified concern” and that the “transmission needs to be replaced due to internal failure.” The transmission replacement was initially declined by my vehicle service contract administrator, and only the torque converter was authorized. The dealer replaced the torque converter but documented that the condition was only more intermittent and that the vehicle “will still need transmission as originally diagnosed.” In August/September 2026, the transmission and torque converter were replaced but bump remained. The dealer then identified a bent front propeller shaft and replaced that as well. The vehicle continued to have drivetrain-related bump as before causing problems with acceleration. The dealer later raised a concern about different tire tread depths/patterns for first time after 8 weeks.The tires were the tires that came on the vehicle when I purchased it. The dealer told me that the tire condition “could cause a problem later.” I subsequently had the tires measured elsewhere, with tread depths of approximately 5/32” and 8/32” on two tires. I purchased 4 new tires and the problem got worse Of particular concern, a dealer employee also told me by text that they had “other G80 here with same problem that need transmissions.” I am not claiming that this statement establishes how many vehicles are affected only information that may warrant further investigation.

UNKNOWN AIR CONDITIONER WORKS WELL FOR ABOUT 1 HOUR, THEN SUDDENLY THERE'S A FUNNY NOISE AND THE HEAT COMES OUT INSTEAD OF COLD AIR. WE HAVE INFORMED GENESIS DEALER ABOUT THE PROBLEM, BUT THEY SAID IT WOULD NOT BE COVERED UNDER WARRANTY. WE HAVE SEEN MULTIPLE REPORTS OF THIS ISSUE BUT GENESIS HAS NOT ISSUED A RECALL FOR THIS POTENTIALLY DANGEROUS AND HAZARDOUS PROBLEM.

There is a recall on my 2020 Genesis g80 3.3t regarding a faulty turbo oil feed pipe causing the car to leak oil and a safety risk that could cause a fire. Vehicle had no issues prior to me having towed to Genesis north of Cincinnati other than the supply pipe leaking oil. The next day after them performing repairs on my vehicle I receive a text as well as an email stating that my service is complete. In the text message it states that my car is complete and is ready to be picked up but the car is now leaking coolant and the oil leak is not repaired. Genesis did not properly repair the issue and is still leaking oil. Repair includes work done to the coolant system being bled annd refilled with coolant . Now my car is also leaking coolant after them attempting repairs

AC stops working while driving on hot days, airflow stops and the situation is very dangerous. Tried to get the dealer to fix it, to no avail. I've been dealing with this dangerous (temperatures reached more than 110 F, without airflow) problem for two years. We are more than 20 owners of these luxury cars experiencing the same problem. I can provide their names and VINs upon request.

AC stops running during very hot days, air flow stops and heat inside the car gets dangerously high. There are multiple complaints about this in a Genesis blog, and dealers are unable to reproduce the problem to find the problem. I contacted Genesis America and they cannot do anything because service technicians are unable to diagnose the problem. Genesis MUST do something about this. I can provide snapshots of the blog with the multiple complaints. This started sometime in the 2023 summer.

It is dead everyday and I have to jump it I noticed when I attach a power source it makes very odd noises. I feel the current recall you have on the g80 2020 may be the issue. It runs extremely hot wit no warning lights showing. I have had a lot of brake dust and the car is hot fast. Also issues with usb and when connected to phone it sound like crackling and volume sounds odd unless I unplug and replug. Replaced battery twice in a year

The contact owns a 2020 Genesis G80. The contact stated that upon starting the vehicle, the check engine warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed that rodents had chewed through the soy-based wire coating. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer who provided the same diagnostic and repaired the vehicle; however, the failure persisted. The vehicle was taken back to dealer where it was diagnosed that rodents had also chewed through the starter wiring. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 12,000.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly.

Some Genesis vehicles may be equipped with a parking distance warning (PDW) sensor(s) that may trigger various DTCs and display warning messages on the instrument cluster, resulting in the PDW sensor(s) failing to detect nearby objects or triggering multiple false alarms. This condition may be a result of external damage to the PDW sensor membrane or sensor cover from rock chips or road debris, a collision, or previous vehicle repairs or modifications.

The National Highway Traffic Safety Administration (NHTSA) has identified the presence of substandard and dangerous driver’s-side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN). These inflators were not supplied, approved, or authorized by the vehicle manufacturers and have primarily been found in vehicles that previously experienced a crash and underwent airbag replacement using non-genuine parts. These dangerous inflators have ruptured during deployment, posing a serious risk of injury or death due to metal fragments entering the vehicle cabin. To date, Hyundai is aware of three people who have died while driving a Hyundai vehicle with one of these substandard replacement airbag inflators that deployed in what likely would have been a survivable crash. NHTSA has issued a public advisory urging vehicle owners and service professionals to have vehicles inspected if there is reason to believe that a non-genuine replacement airbag may have been installed. Vehicles with salvage or rebuilt titles, prior airbag deployments, or unknown repair histories may present a higher risk. NHTSA strongly cautions against self-inspection by vehicle owners and recommends inspection by trained technicians.

The National Highway Traffic Safety Administration (NHTSA) has issued an urgent safety advisory regarding dangerous, counterfeit driver‑side airbag inflators manufactured by Jilin Province Detiannuo Automobile Safety System Co., Ltd. (DTN), that have been identified in U.S. vehicles following prior crashes, theft, or non‑certified airbag replacements. These inflators are not approved for use, may rupture during deployment, and have caused serious injuries and fatalities. Please see attached announcement, provided by NHTSA, for more details.

This bulletin provides information regarding condensation related to the accumulated moisture in the headlamp, rear combination lamp, daytime running lamp (DRL), or fog lamp. This TSB illustrates the various causes of condensation inside the lamp assembly. Lamp assembly replacement is NOT necessary in most cases. This condition can be eliminated by turning on the lamps with the engine running for several minutes or during normal driving operation.
