The problem has been reported, inspected, and confirmed by a dealer. The component has not been inspected by the manufacturer, police, or independent service center. There were no warning messages, lamps, or other symptoms of the problem prior to failure. The problem first appeared when the vehicle was under 15,000 miles. The dealership advised that the worm shaft assembly needs to be replaced.

• 12/21/2023· ENGINE

  In May of 2023 my check engine light came on. Took the car to the dealer and the diagnosis was that the egr cooler was the culprit so they replaced it and everything was fine until 12/21/2023. I am driving on the highway and suddenly I hear a loud alarm and upon checking my instrument cluster I see a warning for engine overheating, the heat was on but suddenly the smell of something burning covered the entire cabin of the vehicle. I had to pull over to the side in the middle of a busy highway in freezing conditions and shut my engine down to avoid further damage. I believe the egr cooler has failed once again inly this time leading to a more terrifying experience. My car was towed to the dealership but I am worried for myself and others with similar vehicles I would not like anyone to experience what I did. I have seen multiple online forums with people complaining about the same situation. Mileage was around 57,900 miles when this occured. I bought the car with 30,000 miles as a certified preowned model. I kindly request for a recall for affected sonatas manufactured from the year 2020 to ensure our safety on the road. If it was not for warranty I would not be able to pay for the repairs

  I own a 2020 Hyundai Sonata with factory-applied paint. The vehicle developed paint peeling/clear-coat failure on the driver-side rear quarter panel without any prior damage, accident, or repainting. The paint began separating from the body, exposing the underlying surface. I brought the vehicle to an authorized Hyundai dealer. The dealer acknowledged a paint adhesion failure and submitted the issue to Hyundai. Hyundai declined to fully cover the repair, stating the model year was not included in their paint warranty extension, even though similar peeling paint defects have been acknowledged and covered by Hyundai on earlier Sonata model years. The dealer ultimately repainted both rear panels due to the nature of the failure, but Hyundai required me to pay approximately 20% of the repair cost as a goodwill arrangement. I was not offered a full repaint or full reimbursement. I have also observed early signs of potential paint adhesion issues around the rear window frame, raising concern that the defect may progress to other areas of the vehicle. This appears to be a manufacturing paint adhesion defect rather than normal wear, and similar issues have been widely reported on Hyundai vehicles. I am reporting this issue to document a recurring paint adhesion defect on the 2020 Hyundai Sonata and to assist in identifying a potential pattern affecting additional vehicles.

  I believe the transmission malfunctioned as I reached 60 MPH / 4000 RPMs on the highway when it suddenly did not want to accelerate past that. The more I stepped on the gas pedal, the more it slowed down. I attempted to use the paddle shifters to shift up or down, but I was unable to shift up and shifting down did not allow me to accelerate past 4000 RPMs. The flow of traffic was faster than I could keep up with, and not being able to accelerate made it unsafe to be on the highway. I had to pull over, and get off of the highway. I found that others have reported this same issue online with the same make/model/trim, but I have not had time to take it in to be looked at. No warning lamps, messages, or other symptoms prior to failure. I only noticed when I got on the highway and needed to reach speeds greater than 60 MPH. Turning the car off, waiting a bit, then starting it again seems to have resolved the issue, but I am still uneasy with this having happened so suddenly. I fear the issue may return in the future based on what I have read online. The car is available for inspection upon request.

  Wiring harness under fuse box is not making a consistent connection and is causing the blower amp to overheat and disconnect. When this happen, cabin air doesn’t blow and the front and rear defrost stops working. The only way to make the blower engage is by removing the fuse box cover and tapping the 30 amp fuse things. I’ve taken my car to the dealership for this specific problem 5 separate times, and it was supposed to be corrected. Due to this poor connection, I am now about $1200 into repairs / replacing parts that aren’t the root cause.

  The component that failed is the fuel tank system. While driving, the fuel tank expanded, causing significant damage to the rear section of the vehicle. This issue resulted in the rear seat rising up, and the bottom rear seat cushion detaching from its securing clamps. The check engine light came on, and gas started leaking from the fuel cap. The fuel tank has moved upward by about 3 to 5 inches, no longer resting on the factory fuel tank straps. The sheet metal underneath the rear seat was crumpled, and the fuel pump access cover bent. The vehicle is currently at College Park Hyundai and is available for inspection upon request. My safety and the safety of my children were significantly compromised. The loud popping noise startled us, and the fact that the rear seat lifted and detached posed a serious risk to the passengers in the back seat. Additionally, the gas leak created a fire and explosion hazard, putting all occupants of the vehicle and other drivers on the road at serious risk. This incident potentially violates the Fuel System Integrity (49 CFR 571.301) regulation, which ensures that a vehicle's fuel system is designed to prevent leaks and fire hazards. Moreover, the unexpected movement and detachment of the rear seat could be a breach of Occupant Protection (49 CFR 571.207 and 571.208), which govern the safety of seating systems and occupant crash protection. The issue has been confirmed by the service center at College Park Hyundai, where the vehicle is currently being inspected and evaluated. The vehicle is being inspected by the manufacturer’s authorized service center at College Park Hyundai. It has not yet been inspected by police or insurance representatives at this time. The check engine light came on immediately after the loud popping noise and the detachment of the rear seat cushion. Additionally, the gas gauge suddenly dropped to empty after the incident, even though the tank was not empty prior to the malfunction.

  Driving on the Interstate at 65mph the car suddenly goes down to 5mph. Unwanted deceleration! At the same time the dash warning lights come on. Check engine and ABS. This happened 3 times now. 2 times on the Interstate in heavy traffic and once going 35mph on a back road. Miraculously we were able to pull over without any cars slamming into us. This unwanted deceleration happened on July 28, August 18 and Sept 13. Each time after pulling to a safe area we turned the engine off, waited a few minutes and turned it back on. Then resumed normal driving speed. Brought it to the dealer after each time. This shut down started after the car was only 4 months old with 2,983 miles on it.First time they said they couldn't find anything wrong and reset the computer, said if it happens again they will look into it more. The second time they replaced a Body Assy-Throttle and Gasket. The 3rd time they replaced the front wiring assembly control. I have all the repair paper work. We were driving playing Russian roulette wondering when it will happen again. With cars speeding around us we were lucky no one was close on our tail. This is an extremely dangerous situation. Each time it was beautiful sunny weather, two times heading to the beach, 3rd time heading to NH after 2 hrs of driving and one hour stopped, resumed driving for 20 min when it happened. No common denominator. I hope that this is not happening to others. I have reported this issue to Hyundai Motors America and they have offered me $500 and 60 days to release them from any liability or claim.

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.

  The AC Fan in my car quit working. Took it to a repair shop where I was told that the AC Blower Motor went bad. The blower motor was drawing too much amps and caused the blower motor fuse to melt into the wiring harness for the blower motor along with melting several other fuses nearby including the fuse box. The cost to repair this correctly fixing and addressing all parts damaged was $5000. Because my vehicle is out of warranty due to mileage I contacted Hyundai who stated that I had to go and pay another diagnostic fee at a Hyundai Dealership to have them look at it. They continued to tell me that the vehicle was out of warranty but would not assist in providing information to get the issue resolved at no cost to me.

  While exiting the vehicle there was a loud pop from under the drivers seat. Upon inspection the left front weld attaching the drivers seat to the positioning bar to raise and lower the seat bottom had failed and separated completely. This causes the front seat bottom to sit at an angle and not fully attached to the structure of the car, causing a severe safety issue in the event of an accident as the driver is not properly aligned for the airbag, the seat belt no longer aligns correctly on the body, and there is a greater risk of full seat detachment in a collision or while simply driving.
