2021 Genesis G80

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.

Brake pedal concern. When pressing the brake pedal in Drive but while the vehicle is not moving there is a tapping sound and feeling coming from the brake pedal.

(front) 245/40R20 (rear) 275/35R20 Rear passenger tire failed, sidewall failure. Instantly went to 0 PSI on dash notification. A cop helped us change it. 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.

All lights warning lights illuminate and gauges stop working. Loss of functionality includes critical control and safety systems and features: •No Speedometer •No Turn Signals •No Tachometer •Odometer not recording miles •Airbag warning •Electric power steering system warning •Steering and driving assist failure •Brake System Failure Warning •ABS Failure Warning •Collision avoidance system failure (forward and rearward) •Check engine •AWD system warning •Lane keep and lane change assist system failure •Blind spot monitoring system failure •Reverse and surround view camera failures •No infotainment or radio control on center stack •Windows and trunk release inoperable •All in-car electronics •On-board maintenance system warnings, random resets All off the above failures occurred without any prior indication of an issue, while vehicle was in motion and being driven on public roads with other drivers and vehicles nearby. These are repeat and reoccurring issues, first appearing at approximately 3,900mi on 01/20/2022. This vehicle is not safe to be driven. 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.

The manufacturer was made aware of the failure and referred the contact to two dealers. The tire and vehicle failure mileages were not available.

The local dealer was not contacted. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was 29,034.
