SERVICE BRAKES
My vehicle, a 2014 Hyundai Sonata Turbo, is having brake lock-up issues. It seems to be related to the AVS (Automatic Brake System). This happens mostly when the vehicle is parked on a hill and the brakes lock up when I start moving. This has been happening for several months, but my mechanic hasn't been able to find the problem. I made an appointment with Hyundai to find out what the issue is, but they told me there's no recall related to it.

STRUCTURE:BODY, UNKNOWN OR OTHER
The vehicle’s dashboard continuously displays a “hood open” warning even though the hood is fully closed and securely latched. The hood has been physically inspected and confirmed to be closed, yet the warning persists. The issue appears to be related to a faulty hood latch sensor or switch, which is part of the hood latch assembly. The warning is inaccurate and does not reflect the actual condition of the hood. I am requesting that NHTSA review this issue for potential investigation, as it may represent a defect in the hood latch sensor system on the 2017 Hyundai Sonata that could affect multiple vehicles and pose a safety risk.

I am filing a complaint against Hyundai Motor America regarding denial of defect coverage for my 2016 Hyundai Sonata (VIN: [XXX] ). The vehicle is experiencing excessive oil consumption and triggered diagnostic code P1326. The dealer confirmed only one quart of oil remained in the engine and noted a valve cover gasket leak. Hyundai’s Tech Line instructed a gasket replacement and oil consumption test, but Hyundai corporate formally declined coverage, citing mileage and second-owner status. This is not a routine warranty claim but a defect claim. Oil consumption defects in Hyundai Theta engines are well-documented and have been subject to recalls, Technical Service Bulletins, and class actions. Defect coverage should not be limited to first owners. I am requesting reimbursement for the valve cover gasket repair, acknowledgment of the oil consumption defect, and corrective action to ensure Hyundai honors defect-related coverage fairly.

FUEL/PROPULSION SYSTEM
Hello Sir/Madam, While driving on Interstate I-75 at approximately 70 mph, the yellow check engine warning light suddenly illuminated. Immediately afterward, the vehicle began to shake violently, lose engine power, and run extremely rough. The vehicle experienced a sudden loss of power, and pressing the accelerator pedal did not result in normal response or acceleration. The throttle input was significantly reduced, making it difficult to maintain speed and safely control the vehicle. At highway speed and in heavy highway traffic, if we had not been able to safely exit the roadway, this loss of control could have put not only the occupants of this vehicle but also other drivers at serious risk. Fortunately, we were already in the exit lane, and a McDonald’s parking lot was located immediately off the exit. This allowed us to leave the highway quickly. Otherwise, this situation could have been extremely dangerous in active, heavy highway traffic. As the vehicle continued to shake, a strong smell of gasoline and a burning odor entered the cabin, raising concerns about a possible fire hazard. We safely stopped the vehicle in the McDonald’s parking lot and then shut the engine off due to the severity of the symptoms. After shutting the vehicle off, we attempted to restart it, but the engine would not start. The vehicle had to be towed to a Hyundai service center for inspection. The Hyundai service center later confirmed that the failure was caused by a faulty fuel injector, and they have changed all 4 injectors as I attached receipt from Hyundai This failure created a serious safety risk due to sudden loss of engine power, reduced accelerator response, severe shaking at highway speed, and fuel and burning odors inside the cabin. Regards

BACK OVER PREVENTION: WARNINGS, FORWARD COLLISION AVOIDANCE: WARNINGS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
On [XXX] while entering 2 car garage with no other cars in garage, the subject vehicle which is a HEV, changed from the electric drive mode to gasoline mode at the garage door and driveway apex. Immediately, the vehicle uncommandedly surged forward from approximately 1mph. The vehicle impacted a large refrigerator and small table causing severe front end damage. No airbags deployed and I was not injured. Although, my neck is sore from whiplash. Seatbelts were employed and vehicle was being operated at less than 1mph, standard for entering a two car garage. There were no warnings, lights, or sounds from the multi function display or any system emergency braking applied immediately before the collision.Just a violent surge forward that I could not quickly apply the brakes to avoid this collision. It is my feeling something electronic failed to operate or was unable to understand the driving environment at the time of impact. The change in driving mode from electric to gasoline was very abrupt and instantly resulted in the surge forward with no concern for what was a potential collision hazard ahead. Severe damage was done to front end only. Resulting in a very high repair cost and may likely result in the vehicle being considered a "total loss". This is currently ongoing with insurance and collision repair facility. Unresolved currently. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
I was driving my 2014 Hyundai Sonata in a rural area when smoke suddenly entered the cabin from the engine compartment. Two bystanders waved me down, alerting me that they could see fire underneath the engine compartment. I immediately stopped the vehicle, turned it off, and exited safely. I attempted to contact 911, but reception was poor. The fire spread from the engine compartment and engulfed the vehicle, producing thick smoke that created a serious safety risk. Emergency services arrived approximately 15 minutes after being notified and extinguished the fire. The vehicle burned for approximately 30 minutes in total resulting in total loss. There were no warning lights or messages prior to the fire. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives beyond the fire report. It was towed and is being stored on private property awaiting investigation.

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.

I started smelling a little gas in the 20th. And on the 21st it got a lot worse so I took it to the dealership. This is the same place that replaced the engine because it failed and it was a recall. I let them know of the recall and they said it is not covered. They told me it was the high-pressure fuel line that connects to the pump. I have provided a picture of what the tech said.

My 2016 Hyundai Sonata experienced a sudden engine failure while in operation with no prior warning lights or symptoms. The engine seized unexpectedly, creating a safety risk. This failure appears consistent with known engine defects affecting Hyundai Sonata vehicles of this model year. Hyundai Motor America denied my claim without addressing these known defect patterns.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER, POWER TRAIN
I own a 2021 Hyundai Sonata 1.6T, which has an open NHTSA safety recall (25V796000) related to fuel tank pressurization and fire risk. I brought the vehicle to an authorized Hyundai dealership due to a check engine light, reduced performance, and DTC P14EE, which aligns with the recall condition. The dealership refused to treat the concern as recall-related unless I paid a diagnostic fee and later attempted to reclassify the issue as a customer-pay fuel pump repair. During this visit, the dealership replaced a fuel system sensor without my authorization, which I did not approve or consent to. The dealership has not provided documented test results explaining how the recall condition was ruled out and has not documented recall inspection on the repair order. I expressed that I do not feel safe driving the vehicle due to the fuel system recall and drivability issues. The dealership also refused to provide alternate transportation. I am concerned the recall is not being handled in compliance with NHTSA requirements and that unauthorized repairs were performed while attempting to shift a recall-related condition to the customer. I am requesting review of recall handling and dealer compliance.

ENGINE
My 2017 Hyundai Sonata Sport Limited 2.4 has a known engine defect causing excessive oil consumption. The vehicle was at an authorized Hyundai dealership for the oil consumption test and had been approved for a new engine replacement. Prior to the repair, I completed $2,300 in maintenance, specifically an oil combustion cleaning and spark plug replacement, which the dealership said was required to perform the oil consumption test. While the vehicle was in the dealership’s custody, it caught fire on 12/19/2025 at World Hyundai Matteson. No one was injured, but the car was destroyed. This occurred while the vehicle was under warranty repair, creating a serious safety risk. I am submitting this complaint to document the fire and the associated safety issue with this engine defect.

About a year ago, I went out one morning, and the Rear Passenger Door would not engage or open. I tried using the key fob, as well as manual lock, trying to lock and unlock, and it still would not open. No one can get into the car from the outside. No one can get out of the car from the inside. This especially is very dangerous. Nothing has changed. I would like Hyundai to repair my door, since it is inoperable. In case of accident, fire, or other reason, someone would be locked in to their detriment.

The engine is burning oil around 1 quart every 700 miles. I check the car oil level around every 10 days. I have experienced when I didn't check the oil and the low oil engine light would come on in the instrument panel. Hyundai shows no recall for this 2019 Hyundai Sonata Limited edition. I believe that this type of incident occurred back around 2011 with Hyundai's models for that time
