Fuel/propulsion system

3 reports1 fire
“On 2/17/2026 I was driving from my home to a fast food restaurant one mile away from my home. After picking up the food I dropped the food off about 3 miles down the road to my family member at their work and drove the 3.3 miles back from my family members work to my home. I arrived at my home and was walking into the house around 12:30 pm my car was off and locked. During my drive the car performed completely fine, there was no codes, no noises, no smells, the car drove how i would describe as intended. But at around 12:45 my neighbors were banging and ringing my doorbell to tell me that my car was on fire. I proceeded to escort my aunt and my grandmother out of the home as i watched my car continue to smoke and watched the flames continue to rise. Once removed from the home i called 911 who took my information down and informed me that a similar call was received a new minutes before and that fire, police and EMS were on the way. I watched as the car completely engulfed in flames and the fire department worked to put the fire out. The car is completely lost and resulted in damages to my garage and my other car parked next to it. I know previous genesis models…”

Power train

2 reports
“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.…”

Steering

2 reports
“The contact owns a 2020 Genesis G70. The contact stated while driving at 2-3 MPH around a curve, the contact steered to the left and the vehicle made an abnormal sound. While turning left, the front passenger's side tire inadvertently moved to the right. The vehicle stopped and failed to move. The vehicle was towed to the dealer, where it was determined that the inner tie rod had fractured and detached. The contact was informed that the rack and pinion needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V447000 (Steering) however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 92,000.”
