2021 Genesis G80

The windows do not roll down or up from any of the switches. this was taken in for a warranty repair and after i received the vehicle back. it worked for a day and has now began to do the same intermittent working and not working. where more often than not i am unable to roll the windows down. Along with the memory seat function not recognizing any presses. On vehicle pickup, the memory seat function was not working, the technician immediately hooked his tools up and reset something and got it working again. They said they had replaced a harness to get the door switches working properly. However the same issue has not started again. leading me to believe that was not the cause of the issue. Like before trying to roll the windows down from either the drivers master switch or any of the passenger door switches results in no operation conditions. randomly it will start working for a bit but than go back to inoperable. This problem has been occurring since i got the car and will be calling the dealer back again to express the dissatisfaction and failure to repair what they claimed to have fixed. It has already spent just under 2 months in the shop out of the 3 months that i have owned the vehicle.

Vehicle Information: * Year: 2021 * Make: Genesis * Model: G80 * Vehicle Identification Number (VIN): [XXX] ] * Mileage at time of incident/problem start: Approximately 26,377 miles Problem Description: The issue began around [XXX]. When pressing the brake pedal, whether the vehicle is completely stopped or while driving, a distinct clicking or ratcheting sound is heard. The sound is clearly audible inside the cabin and is slightly louder when listening under the hood. The sound appears to be originating from an area near a valve or other component (possibly related to the brake booster or ABS system). The sound is always present when the brake pedal is depressed, regardless of the amount of pressure applied (whether pressed firmly or smoothly) or the state of the engine (the sound occurs even when the engine is off). Currently, the brakes function and the vehicle is able to stop. There are no warning lights illuminated on the dashboard indicating a fault in the brake system or any other system. Actions Taken So Far: The vehicle has not been taken for service regarding this specific issue yet. I have a scheduled appointment with an official Genesis dealer on the upcoming [May 7, 2025] to have the problem inspected and diagnosed. Reason for Submitting This Report: Although the brakes are currently functional, this unusual and persistent sound from the brake pedal is a significant concern and suggests a potential malfunction in a core component of the braking system. Since brake issues directly relate to the safety of the occupants and other road users, I have decided to report this potential defect to NHTSA for documentation and to contribute to any future investigations regarding the safety of the 2021 Genesis G80 model.

Less than a mile layer going less than 50 MPH (max rating for spare) the front passenger tire exploded. The same cop caught up with us and could confirm that the front tire was there and was now gone.

245/40 R20 (FRONT) 275/35 R20 (REAR) The two front and one rear tire experienced sidewall failures within the first 25,000 of use. The tires have been disposed. I thank god that the failures did not occur at highway speed which could have caused serious injury to me and other motorists. There were no warning before the tire failures. After the third failure occurring on 2/12/23, I changed all four tires to Michelin Pilot Sport All-Season.

It is a danger to its driver (me) and passengers, and also all other nearby vehicles and pedestrians. It remains at Genesis of Akron, despite the inability to be repaired. On November 18, 2022 they required me to turn in the loaner I had been given and I was informed neither Genesis of Akron nor Genesis USA will provide safe transportation during the arbitration or lemon investigation period(s).

The G80 is equipped with a bluetooth system that should read incoming text messages while in drive. (see https://www.youtube.com/watch?v=cxfPQ37jJbI&t=6s) Instead, after I select "Listen" the car tells me "unavailable while Driving." When I close this system message, the display shows the first several words of the text message - allowing me to read the message while in Drive. This is unsafe. My vehicle is not the only one experiencing this problem - see https://genesisowners.com/genesis-forum/threads/voice-text.37457/ for other reports and more details. I have contacted Genesis USA several times with no luck. I have returned the car for service multiple times with no resolution.

Some Genesis vehicles (listed below) equipped with Lambda-III 3.5T-GDI engines may exhibit reduced heater performance due to engine coolant deposits clogging the heater core. This bulletin provides instructions to verify the concern and to replace the front and rear heater core (if applicable).

This bulletin provides information related to the navigation and head unit software changes introduced in the 2026 1st Navigation Map and Software Update. The changes may vary depending on vehicle type, model, and navigation system. Refer to the 2026 1st Navigation Map and Software Update Key Improvements and Additional Improvements tables in this TSB for a list of specific changes. The software can be downloaded via Navigation Updater (NAU) and updated by USB.

Some vehicles may exhibit difficulty starting in cold weather. This bulletin provides the procedure to perform an inspection on the starter magnetic switch for potential freezing and, if necessary, replace the starter magnetic switch (solenoid) assembly.

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.

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.

Some 2020MY and newer vehicles equipped with a front view camera may illuminate certain warning lights and trigger DTC C272246 fault code for the front camera. In the following cases, the front camera auto-calibration range may be exceeded while driving: • If the front camera is not properly installed and is completely or partially detached. • In case of excessive changes affecting the vehicle's balance (e.g., loading excessively heavy cargo in a specific location of the vehicle, or significant under-inflation of the tires). • Specific road conditions affecting the vehicle's balance (e.g., excessive road crown) This TSB provides instructions on how to service the vehicle when the front camera related warning light(s) are triggered due to system out of calibration (DTC_C272246).
