It was smoking from the engine, I immediately stopped the vehicle. My safety was put at risk immediately while being in the vehicle when the air bags deployed hitting me in the face and causing my face to swell. The safety of others was put at risk due to others being right next to me and putting others at risk of engine blowing up. Yes, the vehicle has been inspected by police. There were no warning signs on the vehicle.
I was driving Home from work and I fell a sleep behind the wheel and Hit a park car. The police report states that my impact speed was 50mph. My insurance company is very concerned that my Air Bags or sensors are defective and that I contact you immediately. Due to the damage and impact of the accident.
PUSHED THE PARK BUTTON, SHOWED P ON THE DASH INDICATOR, DOORS THEN UNLOCKED. WHEN EXITED VEHICLE IT BEGAN ROLLING BACKWARD, PARK HAD NOT ENGAGED SLIGHT HILL ONLY. THIS HAS HAPPENED REPEATEDLY. PUSHED BUTTON TO PLACE THE CAR INTO REVERSE AND THE VEHICLE WOULD NOT ENGAGE OR GO ANYWHERE.
Parking malfunction. Parked, running car moved itself to reverse and backed up a driveway crossing a dirt road and hitting a fence and post. This car could have hit and severely injured anyone who was in the path while it was reversing on its own. Car was in reverse and all parking sensors were blaring when the car was found minutes later.
My vehicle was at a manufacturer‑authorized dealership for a federally mandated recall repair. While the vehicle was in the dealership’s exclusive care, custody, and control, it was struck by a third‑party cleaning vendor operating on dealership property and was declared a total loss. I did not hire or authorize this vendor. After the incident, the manufacturer informed me in writing that the dealership would repair the damage at their own expense, separate from the recall work. The manufacturer also stated they were covering the recall‑related repairs and were coordinating with the dealership. They provided weekly updates, monitored the recall repair, and escalated a backordered recall part. Later, after the dealership confirmed the vehicle was a total loss, the manufacturer reversed its position and stated it was “not involved.” The dealership has refused to identify the cleaning company responsible for the loss, their insurer, or any claim information, preventing any direct follow‑up. The manufacturer continues to direct me to “work with the parties involved,” even though the responsible vendor has not been disclosed. This raises concerns about the safety and oversight of the recall repair process, the handling of vehicles during recall service, and the manufacturer’s response when a vehicle is destroyed during a recall procedure.
While stopping at a major highway intersection on [XXX] for a red light vehicle stalls and will not start back up while everyone else continues at a 55 mph mile an hour passing me on each side! This happened more than 6 times . While you’re stuck in intersection,you have to keep trying to start the car eventually it will start . Apparently it is EGR valve and is a very common problem. IT IS NOTED IN THE common problem for this year making model and the repair cost is in the range of $1600 even the dealership said it is a very common problem. They have been experiencing it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
A/C blower motor fan would stop working. Happened twice within less than a year apart. Upon further inspection, multi fuse wiring overheated and melted, ruining fuse and making A/C stop working during 100 temperatures outside. Apparently this is a well known issue with this make and model Sonata. Electrical failure.
I am submitting a safety complaint regarding a recurring, unresolved electrical defect in my 2020 Hyundai Sonata SEL. The vehicle fails to recognize when the ignition is switched off, leaving core vehicle systems active and causing severe parasitic battery drain that leaves the car immobilized. Description of the Problem: False "On" Status: After parking, turning off the engine, and exiting the vehicle, the car continues to register as though the ignition is still active/on (accessories, cluster, or vehicle network remain awake). Severe Parasitic Draw: Because the vehicle fails to shut down its electrical circuits, the 12-volt battery repeatedly discharges overnight or while parked for short durations. Battery Replacement Did Not Resolve Issue: The 12-volt battery was replaced with a brand-new unit to eliminate typical wear, yet the drain and false "on" behavior persisted immediately. Frequency: The vehicle frequently fails to start, requiring constant jump-starts or roadside assistance to operate. Safety Hazard: This defect creates a direct safety risk by repeatedly stranding the driver without warning in public locations, traffic stops, or remote areas. In addition, an electrical system that fails to enter a sleep state creates a potential hazard for component overheating, failure of electronic security and locking systems, or total electrical failure while attempting to restart or operate auxiliary safety equipment. Other Hyundai owners have reported identical issues where the body control modules or ignition logic fail to power down. Corrective Action Requested: I request that the NHTSA investigate this electrical shutdown defect across the 2020 Hyundai Sonata model year to identify whether a faulty Body Control Module (BCM), smart key receiver, or ignition switch relay requires a safety recall and software or hardware remediation.

The A/C evaporator core and the core seal needs replacing on 2020 Hyundai Sonata. Car is 6 years old. I already have a confirmed diagnosis with a PPM refrigerant leak tester at the condensate drain line The diagnosis is 100% confirmed. The evaporator is leaking heavily—we pulled 274 PPM at the drain tube and 177 PPM inside the cabin behind the glove box so refrigerent has been leaking out of the vents. My wife and I were getting headaches for no reason. Our AC has failed and this problem was discovered as the issue and I am paying out of pocket to fix something that should not have failed and has leaked out refrigerent.
Blower motor malfunction at night. Smelled something burning. Extremely hot and humid outside. Windows fogged up inside which greatly reduced visibility. Checked the multifuse which controls the ABS, oil pump, cooling fan, & Blower. I discovered a burnt connection on one of the terminals for the blower. This is a huge safety and fire risk and needs to be addressed ASAP!!!! Upon my research, I’m finding several Hyundai Sonata vehicles having this same exact issue. Kia vehicles are being recalled for this same exact issue. Why isn’t the Hyundai Sonata??
The reverse camera only shows a black screen and will put drivers in danger while not being able to see behind them while reversing. This needs to be recalled and repaired. Especially in situations where a person is reversing out of a driveway onto a major/busy road. Sometimes it works, but a lot of the time it is just a black screen with the green, yellow, and red lines to indicate how far your wheel is turned. But it doesn’t allow you to actually SEE where you’re backing up into or the cars coming from either side of you while trying to back out. It’s very dangerous and it seems to a be manufacturer’s defect that needs to be addressed by the company itself, since they’re the ones who made and installed the product incorrectly.
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 AC/heating blower motor circuit on my 2020 Hyundai Sonata failed intermittently due to extreme electrical resistance overheating and melting the terminal pins inside the engine fuse box. I took it to the dealership and they inspected it said it was out of warranty but it needed part number 18980-09910-FFF and wiring kit 91300L1000-FF to repair at a cost of 780.00 including parts, tax, and labor. This matches the severe design defect acknowledged in Hyundai TSB #25-EE-002H or alternative TSB-24-EEOO-1H. I filed case number 43138757 with Hyundai corporate. For now this just affects my air conditioning. However, the root failure is a known design defect that presents a severe vehicle fire hazard and potential loss of windshield defrosting capability, lights, etc. if the whole electrical system should fail. As you should know the engine bay fuse box (which currently has melted parts) is the "brain" for the car's electrical distribution. It doesn't just power my AC fan; it holds the fuses and relays for the cars fuel pump, engine control module (ECM), headlights, and electronic power steering. If left unfixed and over time as the plastic melts, copper wires will cross and touch each other, causing a massive short circuit. My engine could suddenly cut out and stall while I am traveling at 70 mph on the highway, instantly killing my power steering and power brakes and putting me in extreme danger. Again not to mention the fire hazard this situation is likely to cause. This should be addressed via a mandatory safety recall, so that I don’t have to pay for a known engineering design defect and in case the TBS bulletin fails or further unknown damage has already occurred.
Car was taken to dealership for inspection. Upon inspection, it was determined that the fuel tank had expanded and pushed towards the heat shield, and expanded upward pushing up the back seats of vehicle. It was determined to not safe to drive. Manufacturer contacted me and offered a buyback. Upon their offer of a buyback, it was determined that I would owe the manufacturer approximately $2,000. I have requested that they fix it, and they have refused to give me the paperwork I requested about the car's condition and fixability. I am in the process of negotiating and am filing this complaint for the record.
Fan motor fuse box quit working and ac/heat no longer operational. First time was around October 21, 2025.
