2020 Hyundai Sonata seats problems

Filed Aug 20, 2026 · Seats · FL

The driver's power seat track master assembly (Part#88500-L0030) on my 2020 Hyundai Sonata suffered a catastrophic structural failure while operating. The black plastic bracket housing and aligning the electric drive motor fractured. This caused the motor to pull out of alignment, twisting the driver's seat violently sideways and permanently jamming the tracking rails. This is a chronic, repeat safety component failure on this specific VIN. The original factory seat track assembly suffered an identical mechanical failure and was replaced by warranty on 10/3/2023 at 46,369 miles. This second factory replacement unit failed in exactly the same manner on 8/13/2026 at 82,271 miles-lasting only 35,902 miles under normal operating conditions. I weigh 95 pounds. A driver's seat structurally shifting sideways dynamically presents an immediate, severe crash hazard. It instantly alters driver ergonomics, compromises the structural crash-anchoring performance of the seat frame, and potentially restricts pedal access to the brake and accelerator. The manufacturer is actively denying product liability by classifying internal structural breakages of shielded components beneath the cushion as user "damage" rather than an engineering or climate-related material defect. This tracking component must be formally investigated for systemic failure patterns to prevent accidents.

The car has now been at hyundai of camelback since 10/27/25 (30 days). Hyndai Corporate has repeatedly delayed providing a remedy and keeps telling me they "need another week". I have received no repair plan, and no decision. This violates the requirement for a timely recall remedy. The defect caused structural damage and created a serious safety hazard. "

In early May 2025 while driving around 40mph, I heard a very loud pop which startled me. Pulled over and looked back and noticed my backseats were push up out of place. I attempted to put the seat back into place but it wouldn’t fit into the latch anymore. The framing underneath the seats looked pretty damaged so I took it to a local mechanic. After doing some research, he found information for a check valve/fuel tank recall (Service Campaign 9B1) and then advised me to go a Hyundai dealership. I attempted to take it to the dealership, whom sent me away after I advised them of what happened. I came back the next day asking them to take a look at while informing them about the recall that could be related. Later that evening, they called and said the issue was directly related to the recall and the repairs would be covered. My car was in their possession for from 5.12.25 to 7.25.25 without any updates or instructions on what is happening. I was told they’re waiting to hear back from Hyundai Manufacturer on how to proceed. They returned my car to me on 7.25.25 stating everything was repaired. On 7.31.25 they called me back stating my tank needs to be replaced and bring the car back asap. My car was again being repaired and was returned to me on 8.25.25. Now my vehicle will not start randomly sometimes. At this point, I’m under the impression my vehicle is no longer safe as all the issues I’ve been facing are fuel related.

My wife and son experienced a terrible situation on the way home from training. They had to stop at the nearest gas station due to the vehicle showing extremely low gas in the tank during a short drive home. The fuel gauge initially showed about half a tank but drastically dropped on the way home. They stopped at a gas station to add fuel but during the process, fuel starting spewing out of the tank. The vehicle was scheduled to be dropped off at a later date for an open recall (service campaign 9B1). I called the dealership and told them I needed to get the vehicle in right away due to the incident. After bringing the vehicle to hyundai, they told me that the fuel tank exploded causing the tank to swell all the way around. Because the tank is located under the rear seat, we constantly heard air coming in due to the rear seat not seating properly. The check engine also was on and we smelled fuel while driving the vehicle. Hyundai representatives has been avoiding my calls to the point where I had to go in person for an update. Apparently, a district manager had to come inspect the vehicle to advise the dealership how to write up the request to send to corporate.

I had the check engine light come on about 4 times in my 2020 Hyundai Sonata 1.6L this year in 2024. I took the car to a technician to get looked at each time it came on. The codes and bulletins kept pointing to fuel system issues. Each time, every service tech said it was a small issue and claimed to fix the issues. The final time a tech seen it lifted the rear seat and found out that the gas tank expanded and the back seat buckled up. The backseat metal frame is bent and messed up. I was flagged down by several drivers ?that noticed gasoline leaking from my driverside rear. My child and I were in dang? er and had to pull on the side of a major highway and stay several hours until someone picked us up. The problem has been confirmed by the hyuandi service center. They said another vehicle experienced this same issue. I was in fear for my life and my child's life because it could have caught fire and/or exploded.
