2020 Genesis G70 Complaints

POWER TRAIN — Filed 06/26/2026

On XXX, I delivered my 2020 Genesis G70 3.3T AWD Prestige (64,267 miles) to Jenkins Genesis of [XXX], for routine factory-recommended maintenance, including transmission, transfer case, front differential, rear limited-slip differential (LSD), brake fluid, and cooling system services. Before this visit, the vehicle had no history of drivetrain problems. It had recently completed an approximately 8½-hour drive from [XXX] to [XXX], followed by three weeks of normal driving, without any binding, vibration, shuddering, abnormal turning characteristics, warning lights, or drivability concerns. The dealership retained the vehicle for four days for what was represented as a one-day service. On XXX, I was told the vehicle had been road tested and was safe for release. **Immediately after taking delivery**, the vehicle developed severe drivetrain binding, violent shuddering, heavy vibration, and significant resistance during normal turns, creating an immediate safety hazard. I returned directly to the dealership. After initially stating they could not duplicate the condition, the dealership ultimately diagnosed **both rear CV half shafts as failed** and prepared an approximately $4,500 repair estimate. The dealership later performed a second rear LSD fluid service **without my knowledge or authorization** after concerns were raised about the original service. They initially offered to replace both rear CV half shafts at no cost, but later withdrew that offer and returned the vehicle to me with both rear CV half shafts still broken. I respectfully request that NHTSA investigate whether improper drivetrain service procedures, incorrect lubricant application, inadequate post-service inspection, or another safety-related condition can cause catastrophic driveline failure immediately following routine maintenance. I am also concerned that the forces sufficient to fracture both rear CV half shafts may have damaged other AWD drivetrain INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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 have had recalls for issues in the engine bay that could result in fires. I do not see a recall for my vehicle but given the unexplainable cause of the fire at this time, believe it may be beneficial to submit a report.

FUEL/PROPULSION SYSTEM — Filed 09/03/2025

My 2020 Genesis G70 is affected by Recall 24V-528 (high-pressure fuel pump defect). About 10 months after the recall service was marked “completed,” my car began showing DTC P0088 (Fuel Rail/System Pressure Too High), which is directly tied to the recall defect. On 8/30/25 car was hesitating when just slowly pulling out of driveway, and check engine light came on and stayed on. The car jerks and vibrates when foot is on the gas. There is now a very strong gasoline odor inside and outside the car, which was also noticed by a Genesis dealership employee when I pulled into the service garage. This raises serious fire and safety concerns. The dealer has told me the fuel pump and fuel line must be replaced. While all parts should be covered, I am currently waiting to hear from the dealership in regards to if Genesis approves/agrees to cover the costs of the repairs needed to my car. I was forced to drive 1 hour and 40 minutes to the nearest Genesis dealership on 9/3 while the car was unsafe, with my child in the vehicle at times. This was extremely dangerous. I was also initially told I would have to either drive the unsafe vehicle back home while waiting for approval or pay for a rental myself. Only after I became very upset and crying, was I given a loaner. That loaner has a 100-mile per day limit, yet I live about 100 miles away from the dealership, making it impractical. This defect is ongoing and unresolved. Genesis has not yet confirmed coverage of all related parts, and I am concerned the recall repair was inadequate. Safety Concerns: Risk of fuel leak/fire from defective pump/fuel system. Strong fuel odor indicating vapor or liquid leak. Unsafe requirement to drive long distance while defect is present. Dealer attempting to deny full repair coverage under recall.

We were told they don't do them at a few Genesis dealerships in the area and then one told they don't have the the parts and to check back with them and that was months ago and the still don't have what's needed. I am fearful for my family's safety and can't seem to get any assistance in getting this matter resolved. We visited the following dealerships: West Houston Hyundai Genesis 16803 Katy Fwy, Houston TX, 77094 Genesis of Spring 20440 Interstate 45, Spring TX, 77373 We called via phone the following dealership: (and was told they don't service Genesis) Sterling Mccall Hyundai 10301 Southwest Fwy, Houston TX, 77074

UNKNOWN OR OTHER — Filed 07/23/2024

Vehicle's high pressure fuel pump malfunctioned while driving causing the car's speed to decrease erratically causing a safety risk. The local Genesis dealer acknowledges that the high pressure fuel pump needs to be replaced and is the subject of a recall, but is requiring me to pay for the repair despite the recall notice stating that: ". . . THE HIGH-PRESSURE FUEL PUMP WILL ALSO BE REPLACED. THIS REMEDY WILL BE OFFERED AT NO COST TO OWNERS FOR ALL AFFECTED VEHICLES, REGARDLESS OF WHETHER THE AFFECTED VEHICLES ARE STILL COVERED UNDER HYUNDAI/GENESIS NEW VEHICLE LIMITED WARRANTY."
