Oil pressure sensor failure caused oil to leak into the injector harness damaging components and engine shutdown. Because this was a sudden engine shutdown and safety-related loss of motive power caused by an oil pressure sensor failure this presents a safety risk

ENGINE AND ENGINE COOLING
The contact owns a 2018 Hyundai Sonata. The contact stated that while receiving an oil change, the technician advised that the oil level was very low. The contact stated that the low oil warning was intermittently illuminated. The contact was advised to take the vehicle to a dealer to be diagnosed. The contact had taken the vehicle to a local dealer, where an oil consumption test was performed. The contact was advised that the vehicle was operating normally. The contact stated that the low oil warning light was illuminated again. The vehicle was taken back to the same dealer, and the oil level was topped off; another oil consumption test was suggested. The contact researched online and related the failure to a known issue of oil consumption that could lead to engine failure. The contact called the manufacturer and asked about an engine replacement because the vehicle was still under warranty. The manufacturer informed the contact that a combustion cleaning had to be performed to determine if the engine needed to be replaced. The contact stated that the vehicle was taken back to the same dealer who performed the combustion cleaning; however, the excessive oil consumption remained, and there was evidence of burned oil coming from the exhaust pipe. The contact called the dealer and was advised that another oil consumption test and combustion cleaning were needed. The vehicle was not repaired. The failure mileage was 103,235.

ENGINE, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
Subject: Non-Collision Engine Compartment Fire - 2010 Hyundai Sonata (VIN: [XXX] ) "On dec 19 2025, my 2010 Hyundai Sonata suffered a sudden, non-collision fire that originated in the engine compartment. While there are currently no 'open' recalls on this VIN, I am formally reporting this incident as it matches the failure patterns documented in NHTSA Defect Petition DP18-003 regarding non-crash fires in Hyundai/Kia vehicles. Preliminary inspection of the damage shows characteristic signs of a manufacturer defect, specifically potentially related to a connecting rod bearing failure leading to an engine block puncture and oil ignition, or an electrical short in the ABS module—both of which have been subjects of major Hyundai fire investigations and class-action settlements (e.g., Engine II settlement) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
My 2022 Sonata has had to have its fuel injectors replaced two times in the 3 years I've had it. On 12/18/2025 My car started to become very slow and could not reach over 20mph, and started to smell like gasoline and shake slightly. I had to get it towed to the hyundai dealership and there they told me that the fuel injectors need replacing. I had the same exact problem with this car before where I had to get the car towed to hyundai and then they had to replace the fuel injector.

FUEL/PROPULSION SYSTEM
My vehicle had Hyundai Safety Recall 227 (fuel tube replacement) completed on December 7, 2022. After the recall repair, the same fuel-system symptoms returned. A Hyundai dealership diagnosed failure of the high-pressure fuel pump and high-pressure fuel pipe and stated the condition was critical and a safety risk due to fuel system involvement and potential fire hazard. Hyundai Motor America declined assistance, citing vehicle age and mileage, despite this being a recurring fuel-system safety issue following a recall repair. The vehicle continues to present fuel-related safety concerns, and operating the vehicle poses a potential fire risk. In addition, the estimated repair cost exceeds $2,000, which represents a significant financial hardship for a safety-related defect that occurred after a recall repair. I am submitting this complaint due to concern for vehicle safety and the recurrence of a fuel-system defect after a manufacturer safety recall.

STRUCTURE:BODY
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.

ENGINE
The vehicle experienced sudden engine failure due to rod bearing damage. The engine seized without warning and required towing. A Hyundai dealership confirmed rod bearing failure consistent with known Theta engine defects. Hyundai denied engine replacement coverage because a software update (Campaign 953 / KSDS) was not completed; however, I never received notice of this campaign. The campaign does not appear on the NHTSA VIN lookup for my vehicle, and it was still listed as outstanding in Hyundai’s system at the time of failure. The sudden engine failure created a safety risk due to loss of power.

My vehicle has an oil consumption problem. I put in 5 quarts of oil last week after changing the oil three weeks before this. I am down today December 19, 2025 2 1/2 quarts when I put in 5 quarts last Friday. Hyundai motor Corp. says I have to pay for the $90 oil change to do the oil consumption test then I have to go back 1000 miles later and pay $600 for an oil combustion cleaning and drive it another thousand miles and come back and see the oil level to see if I need an engine. I think this is absolutely a safety hazard and needs to be taken very seriously for all customers that drive a Hyundai that are having these issues.

The Vehicle: "I have a 2011–2014 Hyundai Sonata with massive underbody rust." The Failed Fix: "Service Campaign 946 was completed on this car in 2017, but it did not work. The rust is now worse." The Safety Risk: "The structural metal is so rusty that I am afraid it will snap while I am driving. This makes the car unsafe." Hyundai is refusing to fix it because the car has a 'branded' (abandoned) title, even though the structural safety issue is still there."

AIR BAGS

The airbag became detached from the steering wheel and impaled into the drivers chest.
