POWER TRAIN
The contact owns a 2025 Hyundai Sonata. The contact stated that while the accelerator was depressed, the vehicle hesitated, jerked, and failed to accelerate as intended. The failure occurred while driving from a stop and while driving at various speeds, causing the vehicle to decelerate during the failure. While depressing the brake pedal, there was a rubbing or grinding coming from the vehicle, and the braking was rough. There were no warning lights illuminated. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not made aware of the issue. The failure mileage was approximately 38,000.

ELECTRICAL SYSTEM
On Feb. 10, 2026, my Sonata began showing a blue screen on the infotainment screen when the vehicle was in reverse. The blue screen contained the message "Incoming Camera Signal Error. Please try again later." Between Feb. 10 and 22, I continued seeing the aforementioned blue screen and message. In addition, I began seeing a green screen with a message "No Camera Signal Received. Please try again later.”. On Feb. 22, I was attempting to reverse from my garage and my camera failed to engage. I saw a black screen without picture when the car was first put in reverse, so I put in park and then switch back to reverse. The camera did not engage and the screen remained on the car's menu. Camera then flashed on briefly and then went back to the black screen, then moved multiple time between to the blue screen with the warning message “Incoming Camera Signal Error. Please Try Again Later.” and the green screen with message “No Camera Signal Received. Please try again later.” The issue eventually began occurring both while in reverse and in drive. During this time frame, I took the vehicle to the dealership on multiple occasions, Feb. 10 and Feb. 19, and they were unable to replicate the challenge. I took the vehicle back to the dealer on Feb. 23, and the issue was replicated. The issue was 'repaired' and picked up on Mar. 19, but had to return 3 hours later due to the same issue then in an exacerbated state. The issue was finally repaired on Apr. 1 after a complete floor assembly replacement. The issues caused the safety concern of limited visibility when driving.

The horn stopped working unexpectedly. Pressing the horn button produces no sound. The vehicle has not been in any accident. This is a safety issue as the horn is required for alerting other drivers in emergency situations.

SERVICE BRAKES
Vehicle brakes sound and feel rough when pressing them. And when backing up the vehicle spotted another car turning in and hit brakes automatically. Car jerked hard as if I hit something. Very rough. Made a scrubbing sound. Does the same when pressing the parking button. It perks and makes the scrubbing sound. Just purchased Vehicle 2weeks ago. No inspection on it yet. A warning light about the approaching car but didn't know it was going to hit on brakes by itself so forcefully. Car wasn't near the vehicle just in the scenery of the camera.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
The vehicle is stalling in the acceleration process. I can feel and hear the stall by the air conditioner going out or fading out when it happens while driving. Pressing the gas and it barely moves at times. Makes a noise now while running. Unknown to whether it's electrical or engine or transmission. Pull out in the traffic accelerating but the car wasn't moving at the pace it should have. Could have cause an accident when trying to cross on going traffic. Just got the vehicle 2 weeks ago. No one has inspected the vehicle yet. Going to have it looked at for recalls. No warning lights appeared to reflect an issue, but there clearly is.

POWER TRAIN
The contact stated that while driving at various speeds, the vehicle would jerk upon depression of the accelerator pedal without warning. In addition, the contact stated that on multiple occasions while turning into a parking lot, the vehicle's collision avoidance system would engage while in the vicinity of another vehicle as a warning chime would emit from the vehicle. The vehicle was taken to a dealer where they initially could not diagnose or duplicate the failure. The contact was asked to come and drive the vehicle herself and she was able to duplicate the failure. The dealer eventually diagnosed the vehicle with a failed transmission and remained in the dealer's possession. The manufacturer was notified of the failure. The contact was later informed that they would not replace the vehicle but would replace the transmission. The vehicle had yet to be repaired and remained in the dealer's possession. The failure mileage was approximately 50.

UNKNOWN OR OTHER
The panoramic sunroof/front movable glass panel on my Hyundai Sonata N Line appeared to spontaneously shatter while driving on the highway. Weather conditions were clear and normal at the time of the incident. There was no traffic around the vehicle, no bridges or overhead objects nearby, and I did not observe any object strike the roof before the glass failed. The vehicle has approximately 20,000 miles. The glass suddenly developed widespread cracking and a large opening in the panel. The glass also appeared to lift/bulge upward around the damaged area. There was no obvious impact point or bullseye pattern visible that would clearly indicate an object strike. The failed component was the panoramic sunroof/front movable glass panel. The damaged component is still available for inspection. This created a serious safety concern because shattered glass could have entered the vehicle while driving at highway speeds and could have caused distraction, injury, or loss of visibility/control. The vehicle has been inspected by a Hyundai dealership. I was informed the panoramic roof assembly may require replacement. I am filing this complaint because the failure appeared spontaneous and may indicate a defect or structural stress issue with the panoramic roof glass. There were no warning lights, alerts, or prior symptoms before the failure occurred. Photos of the damage are available for inspection.

ENGINE, SERVICE BRAKES
the car has two issues. brake issue (gas pedal is soft and sinks) and engine power ( gas pedal is soft and not responsive) Brakes are soft and spongy some times and sometimes hard. even you push the brake pedal twice or three time it takes long distance to stop. some times the brake looks good but for short period of time. the brakes inconsistent. I took to the dealer where I bought it hey refuse to repair it. then i took it to another dealer. first time they said no issue with car then second time they they replace the vacuum pump and they found out one of the piston is not firing. they replace the ignition coil. the car still has issue and not fixed. I filed case with the manufacturer but the manufacturer closed the case. After that I file lemon law case.

ELECTRICAL SYSTEM, STRUCTURE:BODY
On April 8, 2026, I returned to my brand-new 2025 Hyundai Sonata Hybrid Limited (purchased as a new ccar on February 10th 2026)_after being away from March 31 to April 6, 2026 (approximately 7 days of normal parking). The vehicle was completely dead — the 12V auxiliary battery had fully discharged. The car remained fully locked. The hood release lever and the 12V battery reset button are both located inside the cabin and were therefore inaccessible. Following the instructions in the owner’s manual, three adults attempted to remove the plastic cover over the mechanical keyhole on the driver’s door handle. None of us could pry or slide the cover off. Hyundai Roadside Assistance dispatched a locksmith. The locksmith had to use an air-inflation wedge tool to force the door open. Once inside, he pressed the interior 12V reset button and the vehicle then operated normally. This incident demonstrates a complete failure mode: the 12V system can die after only a short period of inactivity, and the mechanical emergency-access design makes it extremely difficult (or impossible for multiple people) to enter the vehicle without professional forced entry or risk of damage. The combination left me stranded with no practical way to regain access to my new car. I believe this is a safety-related defect because it creates an unreasonable risk of the driver being unable to enter or operate the vehicle after normal parking, potentially in emergency or critical situations. Hyundai has issued Service Campaign TEBA / TSB 25-01-076H for battery drain on 2025 Sonata Hybrids, but it does not address the mechanical key-cover access failure that turned the drain into a total lockout. It is also not clear the the TEBA is a complete solution to the battery drain problem.

SERVICE BRAKES
I am the original owner of a 2025 Hyundai Sonata purchased new in 2025. The vehicle currently has fewer than 4,000 miles on the odometer. Since early in my ownership, I have experienced a persistent and recurring squealing noise that occurs specifically when releasing the brake pedal after a short stop, and when transitioning from braking to acceleration. This is not an intermittent or weather/humidity-related issue. The noise has been consistent and ongoing throughout my ownership and has not resolved on its own--I was thinking it might since new cars take some time to adjust. At under 4,000 miles, brake components on this vehicle should be essentially new. Brake pads are engineered to last between 30,000 and 70,000 miles under normal driving conditions. A persistent brake noise at this mileage cannot reasonably be attributed to normal wear and tear and is indicative of a manufacturing defect, defective OEM brake pad compound, or a sticking/dragging brake caliper that fails to fully release after braking. I note that NHTSA has previously investigated Hyundai Sonata brake behavior, including a technical bulletin concerning rear brake pads remaining in contact with rotors after a diagnostic self-check cycle, causing a dragging condition in the next drive cycle. My symptoms are consistent with this type of brake drag behavior. Multiple Hyundai Sonata owners have documented the same persistent squeal-on-release pattern on Hyundai owner forums, with some reporting the issue beginning within the first year of new vehicle ownership and dealers being unable to diagnose or resolve it. I have formally reported this issue to Hyundai Motor America Consumer Affairs prior to filing this complaint and have requested warranty coverage. I am filing this complaint to create an official federal record of this defect and to contribute to any pattern investigation NHTSA may conduct on 2025 Hyundai Sonata brake systems.

Driving home and heard what sounded like a gun shot. Upon arriving home we found the moonroof glass had exploded/shattered. Took pictures/video to document. Found online that there have been reports of similar instances happening dating back to 2011 and newer vehicles. Have called dealership to see what next steps are to have repaired as a warranty issue but service department is closed until Monday morning 7am.

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)

BACK OVER PREVENTION: WARNINGS
The emergency rear collision detection system is able to be turned off, but automatically turns on when the car starts. There are situations where the car detects an object and it prevents me from reversing. I disabled this because I use my eyes and have accepted the risk of running into something. I had to move in a hurry two days ago, I tried to reverse out of the way, but the car prevented this when I thought I had already shut it off. Meanwhile I'm getting screamed at to move while I fumble through menus just so I can drive the car I bought. This is dangerous to have automatically on everytime the car starts.
