UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I wanted to report the failure of my rear camera and/or the electrical circuit that is tied to it. It's my understanding that Hyundai has issued multiple recalls across different years/vehicles for issues in this area. My 2019 Sonata is NOT included in those current recalls. I was without my vehicle for a week and was charged over $1600 to repair. The issue was diagnosed and repaired by an independent mechanic. When they system failed numerous error lights/warning went off and continued to cycle thru (plus beeping). I wanted to report this in hopes of continued pressure on Hyundai to add this model/year to their recalls.

FUEL/PROPULSION SYSTEM
NHTSA Recall Number22V312000 I am writing to formally file a complaint regarding my 2013 Hyundai Sonata (VIN: [XXX] ), which is subject to a manufacturer recall #189 due to a fuel line defect posing a fire risk and potential severe injury. Today, I visited Wallace Hyundai in Fort Pierce, Florida, and the service manager Mr. Louis LaRussa and associate employed what I can only describe as a warranty circumvention tactic. They repeatedly delayed my recall repair by claiming I must first complete other optional recalls, unrelated to the fuel issue. They stated that they would not be paid by the manufacturer unless all recalls were done together. This is not only unprofessional but also a disregard for the serious safety hazard posed by this fuel line defect,they prioritize dealership financial interests over customer safety and contradicts the purpose of a safety recall. Furthermore, I was told I would need to leave my car for days or even weeks because parts supposedly must be ordered. As this is a nationwide recall, I expect a swift, ready-to-implement solution. I demand immediate action from Hyundai to honor the recall and ensure my safety is prioritized. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

On April 14, 2026, my 2019 Hyundai Sonata was parked at a retail store parking lot. Returning from the store, I attempted to start the car, and it did not start. I attempted to start it again, and I saw smoke coming out from under the hood. I immediately exited the vehicle and opened the hood. I saw open flames coming out of the engine area, about 4” high. I called 911 and waited about 10 minutes for the fire department to arrive. During this time, the flames engulfed the entire engine compartment and extended vertically above the hood height. The hood eventually melted and fell back onto the engine area. The fire department came and put out the fire. The car is totaled. There were no injuries, thank God!

FUEL/PROPULSION SYSTEM
NHTSA Complaint Statement Subject: Stop‑Drive Recall – Vehicle Held Since March 5, 2026 – No Remedy, No Transportation, Buyback Delayed I am filing a complaint regarding a stop‑drive safety recall that has left me without access to my vehicle since March 5, 2026, and the manufacturer has not provided a timely remedy, transportation assistance, or a completed buyback. My vehicle has been at the dealership since March 5 due to a manufacturer-issued stop‑drive recall. The dealership has confirmed they cannot legally release the vehicle because of the stop‑drive order. The vehicle is not repairable at this time, and the manufacturer initiated a buyback process. However, the manufacturer has been extremely slow to communicate or complete the buyback. Despite multiple attempts to contact them, I have not received a clear timeline, and the process has stalled. I have also not been provided with a loaner vehicle or consistent rental reimbursement, even though the stop‑drive order prevents me from using my car. Because of the delay, I am now facing financial hardship, including a past‑due car loan on a vehicle I cannot legally drive and cannot retrieve. I am effectively without transportation and without a remedy. I am requesting NHTSA’s assistance because the manufacturer has not met its obligations to provide a timely remedy or adequate support for a stop‑drive recall that has removed my vehicle from service for an extended period.

I am reporting a pattern of systemic failures on a 2012 Hyundai Sonata Hybrid with approximately 131,000 miles. This is my second NHTSA complaint regarding this vehicle and manufacturer. Primary Safety Concern — Engine Wiring Harness: During a recent engine replacement at an authorized Hyundai dealership, technicians identified damage to the engine wiring harness and documented in writing that the owner “might have issues with drive ability.” The dealership declined to repair it under the same goodwill program used to replace the engine and returned the vehicle with this known defect unresolved. The harness directly controls engine operation, hybrid system communication, and overall vehicle control. On a hybrid vehicle, a compromised harness presents a serious and ongoing safety risk. This component is available for inspection upon request. Engine Failure: The hybrid system warning light appeared prior to failure. The vehicle was towed to an authorized dealership where diagnostic code P1326 confirmed engine failure. The manufacturer acknowledged this and replaced the engine under goodwill. Additional System Failures: A pre-scan diagnostic revealed simultaneous fault codes across six systems — engine, transmission, ABS, active hydraulic booster, battery management, and motor control unit — including codes U0293 and U1004 indicating lost communication with the hybrid powertrain control module across multiple systems simultaneously. Independent Safety Advisory: A separate independent repair facility documented in writing that the vehicle presented a severe wheel hub bearing noise and formally advised of an extremely dangerous driving condition. Prior NHTSA Complaint: My first complaint to NHTSA involved this same vehicle when the manufacturer refused to provide a loaner during an extended recall-related repair hold, requiring formal escalation before they complied. The wiring harness defect remains unrepaired. The vehicle is driven daily out of necessity.

Our Car is 2016 with 97000 miles with engine failure. Previous driving noticed the Engine will slow down suddenly at times. Preston Hyundai Dealer says bad engine cylinder $6000 is a fire hazzard and needs new engine. I see Hyundai sold 199000 2016 Sonatas and replaced 129000 bad engines. They gave a 120000 mile warranty to the 2016 cars. Hyundai said my car in not on the recall list so they will not pay for an engine. The dealer said the engine rods look okay. An engine should last longer than 97000 miles! Please help! [XXX] [XXX] [XXX] My INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SERVICE BRAKES, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
We think there’s an issue with the abs module and wheel speed sensor because we started having a problem where the brakes wouldn’t work or would stutter. The car would shake real bad it would make an awful grinding sound but normally only when trying to stop at higher speeds or long braking. The only thing that made it stop was to unplug the abs but then other parts of the car stopped working like the speedometer and the sensors around the car. So we got the abs replaced but the new one started doing the same thing. We did some research and it sounds like the same issue Hyundai is having with the palisade. The incident that made us get it replaced to begin with was were driving down the road and we got to a traffic light but when we tried to brake they just didn’t work so we drove through the red light luckily the one person who was supposed to be going saw us and didn’t pull out in front of us so we didn’t get hit. We haven’t taken it to the dealership yet but my sister who teaches automotive repair at the community college is the one who diagnosed it so she said we should report it here so maybe it won’t happen to anyone else. Before we had the brake issue we were having problems with basically everything on the dash not working randomly. We’d be driving down the road and the speedometer and the outside sensors and the gas gauge and the traction control all would go out at the same time it’s the same stuff that went out when we had the abs unplugged so it seems that might be related.

While driving my car with no warning light or any type of sound just cut off engine while driving. I was on busy highway going slightly uphill and was almost rear ended causing car behind me to swerve to avoid hitting me swerving to other lane and almost colliding into another car. I was able to get to middle divider almost but back end of my car sticking out in #2 lane. I was stuck in car for about 10 minutes then got across Street to sidewalk. There was no warning, no smoke etc prior to engine cutting off. Everything still works lights, a/c, radio etc . Engine tries to turn over but then slowly dies out like a battery issue however I have a 2 year old battery and when I charge it or try to jump start it it doesn't start also everything else powers on. I have had it stall 2 times before on L.A. freeway in which I somehow was able to cross over 4 lanes coasting to side of freeway. And at that time was sideswipped by another vehicle to front of car and car kept going and I really didn't have time to think about that while just trying to maneuver safely to side of freeway. The 1 and 2nd time it stalled it did restart after about 10 min. But this 3rd time it hasn't started again. The most recent incident was4/15/26. Another issue is the massive amounts of oil it consumes. I put in 2 quarts a week . But there is never oil leaking on driveway or anywhere its parked so where is oil going. I've had it checked several times and they said that these cars burn through oil and I also told Hyundai dealer about both issue and nothing was ever done. My s Check engine came on and I took in to shop and picked it up after paying alot of money and light was off but about a week later on. Took it back and pick up and lights off running good another couple thousand again. And on and off just randomly and auto mechanic shop said I would need to take to hyundai dealer to see whats happening. Called and told them never heard back. I have more pic of repairs but couldn't load more

2026 hyundai sonata limited hybrid first owner. The sunroof above the driver's seat exploded while i was driving 70mph on the highway. Sounded like a gunshot. It was completely shattered but thankfully did not rain down on me. Local hyundai dealer inspected it and warranty denied from hyundai due to "caused by an outside influence." I did not see or hear any rocks or debris.

ELECTRICAL SYSTEM
Component Involved: Hybrid Propulsion System High Voltage Battery / EV Battery Electrical System Power Train Incident Summary: I am reporting a serious and repeated safety defect involving my 2015 Hyundai Sonata Hybrid. This vehicle has experienced three separate incidents where warning messages related to the EV/hybrid battery system appeared, followed by a sudden loss of forward propulsion. During these events, the vehicle would not move properly or lost the ability to accelerate safely. This defect creates a major safety hazard because it can occur while driving, increasing the risk of being rear-ended, stranded in traffic, collision, injury, or property damage. I transport my small children in this vehicle and no longer feel it is safe. Detailed Timeline: Initial Incident: Vehicle displayed warning messages involving the EV/hybrid battery system and lost the ability to move forward properly. Vehicle had to be shut off and restarted. Independent Mechanic Inspection: Vehicle was inspected by an independent mechanic who advised the hybrid battery system likely needed repair or replacement and recommended service through Hyundai dealership. Dealer Visit #1 – Stew Hansen Hyundai (3/18/2026): Vehicle was taken to authorized Hyundai dealer for diagnosis. Dealer stated they could not duplicate the issue and no repair was made. Second Failure: After release from dealer, same dangerous loss-of-power condition occurred again, resulting in towing and additional inconvenience. Dealer Visit #2 – Stew Hansen Hyundai (4/8/2026): Vehicle returned to dealer for same issue. Dealer performed software update and stated this should correct problem. Dealer advised vehicle had been driven approximately 40 miles and was safe to release. Third Failure (4/12/2026 approx.): Only two days after picking vehicle up on 4/10/2026, same warning messages and propulsion failure occurred again. Safety Concern: This repeated loss of propulsion without warning is extremely dangerous.

FUEL/PROPULSION SYSTEM, ENGINE
I am writing about my concerns on a 2016 Hyundai Sonata SE that I purchased for my daughter in October 2023. After purchasing I took it to my local Hyundai dealer to have it checked out. It was one of the cars that came with a lifetime warranty for the rods DO TO A DEFECT.On January 2024 my daughter was driving on the freeway when all of a sudden it just stopped accelerating and when checked it was a Knock sensor detection system. The dealer took it in and inspected and said it was a defective sensor and replaced it.This made me uncomfortable as I felt the sensor did its job and it was just a matter of time before the rod blew through.During the next few months it became very apparent that the car was going through unbelievable amounts of oil.It had a ticking so we replaced all the spark plugs and noticed oil saturating the plugs and realized a leak in the valve cover gasket which was also replaced.We thought this might be the cause but no oil was on the ground and nowhere on the engine.I just thought it was burning oil but no indicator lights were going off. The car could have no oil and it would not let us know. She's lucky to drive 300 miles a month.She has complained of a strong gas oder and we replaced 2 gas caps and went back to the Hyundai dealer.They told us there's a problem with the fuel filter and pump.If we pay $273 of inspections it might cover it if it's a failing part, and when I did the oil change the car was very low on oil despite the fact that we check it monthly and put 3 quarts of oil in the car.Her car is consuming 3-4 quarts of oil per every 250 miles.This could cause her engine to fail and possibly throw a rod which given the fact she has already taken out one Knock sensor it is just waiting to happen.So as oil disappears every few hundred miles without a warning the engine locks up and if a rod punches through onto the exhaust this can cause it to stall and potentially catch on fire especially when it wreaks of gas from the fuel filter.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
I have a car covered by the Theta II Settlement. Engine, fuel system. Metal shavings found in oil and oil is diluted with fuel and oil if overfilled 1 inch above full mark on dipstick upon pickup from dealership. The vehicle is available for inspection at my residence; however, it is currently grounded as a known safety hazard. The vehicle is exhibiting symptoms of imminent engine failure (audible knocking, P0011 code, and oil dilution). Despite being shown evidence of this(photo and video of oil overfill and watery viscosity) , the manufacturer instructed me to continue operating the vehicle, placing myself, and other drivers at risk of a high-speed collision or vehicle fire. The symptoms (P0011 code and engine noise) were confirmed by an independent mechanic on March 25th 2026. However, during the official Bearing Clearance Test (BCT), the dealership intentionally overfilled the engine oil by 3 quarts (documented via photograph) to muffle mechanical noise and artificially pass the diagnostic and issued a pass on all inspections despite the oil hazard. Hyundai Corporate Case Manager Nikulmar Dhabi has admitted on record that the dealer was out of compliance by "being outside the standard notification time" yet they refuse to provide a safety-compliant remedy. Warning Symptoms & Appearance: Symptoms first appeared months ago when I repeatedly got a P0011 code, however On march 24th 2026 I received an engine light with a P0011 and the car going into limp mode while i drove. Warning signs included a persistent Check Engine Light (P0011) and audible metallic knocking. Upon checking the oil myself after the dealer "inspected" it, I discovered the oil was 3 quarts over the "Full" line, which is a deceptive practice used to mask rod bearing failure.
