ENGINE, FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER
Approximately one month ago I had a high pressure fuel pump installed in my 2018 Hyundai Tucson. While driving on the highway, about ten minutes from home, my car suddenly burst into flames. There were no warning lights in the cockpit. There was no smoke in the cabin. Another motorist flagged me down. I got out of the vehicle just in time for it to become fully engulfed in flame. It burned down on the highway. Police and fire responded. Insurance is investigating. If I was inside the vehicle, I would have certainly died.

POWER TRAIN
The transmission system failed. The vehicle had previously been serviced at a Hyundai dealership for a transmission-related issue and was returned to me as repaired; however, the problem persisted. Shortly after the repair, the transmission failed again, indicating that the issue was not properly resolved. The vehicle is currently available for inspection upon request. The failure occurred while I was actively driving, creating a serious safety risk due to the potential loss of power and reduced ability to safely control or maneuver the vehicle. At the time, my [XXX] child was in the car, placing both of us, as well as other drivers on the road, at risk. The issue was confirmed by the Hyundai dealership following the initial repair attempt. Despite being advised that the vehicle was repaired, the transmission failed again, and the dealership acknowledged that the transmission remains defective. The vehicle has been inspected by the Hyundai dealership’s service department but has not been evaluated by police or insurance representatives. There were no warning lights or messages prior to the failure. The transmission failed unexpectedly after the vehicle had already been serviced and returned as repaired.

ENGINE
While driving at highway speed, the engine suffered a sudden connecting rod bearing failure (Cylinder 3) with no prior warning lamps, messages, or symptoms. The vehicle made a slapping noise, a belt came off, the engine died, and would not restart. The vehicle was towed to an authorized Hyundai dealership. The driver, a [XXX] [XXX] , was able to safely guide the vehicle to a stop without injury. The dealership inspected the engine and confirmed a complete Cylinder 3 connecting rod bearing failure. The technician contacted Hyundai Techline, who confirmed the diagnosis and recommended engine replacement. The estimated repair cost is $6,500. The failed engine is available for inspection at the dealership. This vehicle is a 2019 Tucson with the Nu 2.0L GDI engine, which is covered under the E2 Class Action Settlement for connecting rod bearing defects. Hyundai Service Campaign 966 provides a KSDS software update designed to detect abnormal bearing noise before catastrophic failure occurs. This update was never performed on the vehicle. The 2019 Tucson was not added to Campaign 966 until April 2022, after the vehicle had already been purchased used. The owner was never effectively notified of the campaign and the vehicle was never at a Hyundai dealership where the update could have been performed. Hyundai denied warranty coverage solely because Campaign 966 was not completed, despite confirming the failure is the exact defect type the campaign and settlement were designed to address. The vehicle had only 49,437 miles at the time of failure. The engine failed without any prior warning — the exact scenario Campaign 966 was designed to prevent.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM, EXTERIOR LIGHTING
On March 6th, 2026, I spent the day running errands in normal driving conditions and it created a situation that did not charge the battery or switch to gasoline. Several error lights displayed seconds before the car died. The hazard lights failed within 15 minutes of waiting for a tow truck. The dealership service department charged the battery and gave me advice to run the car at least 30 minutes everyday even if runs only in the garage. They told me that it was user error because I don't need to drive a half hour per day. I am still attempting to determine the real issue and have it addressed.

SERVICE BRAKES, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Hello, In my 2025 Tuscan Hybrid, the vehicle all of a sudden came to a near complete stop driving down the highway at lower speeds due to vehicles in front of me slowing down before a tunnel. While it was apparent I had to slow down, there was no immediate danger to me potentially crashing into the car in front of me which is why I am concerned the car is over reacting to my environment whilst driving.

FUEL/PROPULSION SYSTEM, ENGINE
Component: Engine/Powertrain/Electrical System Incident Description: I am reporting a recurring, life-threatening "Loss of Motive Power" (Dead Pedal) in a 2024 Hyundai Tucson (Alabama-built). On multiple occasions, the vehicle has failed to respond to throttle input during high-risk maneuvers, specifically while merging into 45+ MPH traffic. The vehicle "chugs" and stalls, refusing to exceed 15 MPH despite full accelerator depression. This defect leaves the vehicle and its occupants stranded and defenseless in the path of oncoming high-speed traffic. Technical Context: This vehicle is currently subject to NHTSA Recall 23V-526 (Hyundai Campaign 246) for electronic controller damage that can cause "CAN communication disruptions." I believe the "Dead Pedal" failure is a direct result of these communication disruptions between the engine and transmission control modules. Furthermore, Hyundai has issued TSB #24-AT-001H-1 for "Hesitation when accelerating," yet the authorized dealer (Ed Voyles Hyundai) has been unable to remedy the defect after 84 cumulative days out of service. Safety Risk: This is not a convenience issue; it is a critical safety failure. The unpredictable nature of the power loss makes it impossible to safely judge gaps in traffic. The vehicle effectively becomes a stationary object on active roadways without warning. Manufacturer Response: The manufacturer has been formally notified via certified legal counsel. Despite 79 consecutive days in the current repair attempt (since Jan 16, 2026), the manufacturer has failed to provide a fix or acknowledge the severity of the safety risk. An informal third-party evaluator attempted to dismiss the claim despite the vehicle's documented inability to maintain motive power. We are requesting that NHTSA investigate the adequacy of Recall 23V-526 and TSB #24-AT-001H-1, as these measures have failed to resolve this life-threatening "Dead Pedal" condition in my vehicle.

ENGINE
My 2015 Hyundai Tucson with the 2.4L engine developed a loud engine knocking sound while driving. The knocking became worse and the vehicle became unsafe to drive due to the possibility of sudden engine failure. The vehicle is currently at a Hyundai dealership and has been there for over a month. The dealership denied the warranty claim stating that a different engine component failed instead of the connecting rod bearing. This engine is part of the known Theta II engine defect issue that has caused engine failures in many Hyundai vehicles. A sudden engine failure while driving could result in loss of power, difficulty steering or braking, and could increase the risk of a crash. I am filing this complaint because the engine failure symptoms match the known defect pattern, and the vehicle may be unsafe if the issue is not properly addressed. Hyundai Tucson with 113,000 miles and failing engine. I’ve been told repairs have amounted to $10,000. I was told my car has severe engine failure and must be replaced by Hyundai of the shoals in Tuscumbia, AL. Engine failure is dangerous as a fire may start from a metal piece and also loss of control of vehicle is possible. Hyundai has denied warranty as they say the exact part in theta 2 engine settlement is not failing. I have had to complete recalls on this car since the first payment I made on it. The engine knocking began a month ago and that’s about how long the dealership has had my car.

ENGINE, FUEL/PROPULSION SYSTEM, POWER TRAIN
Car is a Gas Hybrid (not plugin). 3 occurrences over the last couple of months. Car emits a warning sound and a message on the dash says "Check Hybrid System. Stop Safely". Basically right after this message the car starts losing power and stops. Doesn't matter if on freeway or not. You need to find a place to pull over or you stop traffic wherever you are. Looks like Hybrid Battery is completely drained. Can not be re-created. Dealer has it now for the 3rd time. Dealer in the past have not been able to find cause/cure since this issue is not posting any errors to the onboard diagnostic system. Temporary 'fix' is to power off car, and power back on. Looks like this is a 'known' issue though as its being reported by quite a few people online.

ENGINE, FUEL SYSTEM, GASOLINE
The contact owns a 2017 Hyundai Tucson. The contact stated that the vehicle was consuming an excessive amount of engine oil. There was an abnormal knocking sound coming from the vehicle. There was no warning light illuminated. Due to the failure, the vehicle was towed to a dealer, and the excessive oil consumption was confirmed. The contact was informed that the vehicle was included in NHTSA Campaign Number: 21V727000 (Engine), and the engine was replaced. The vehicle was repaired, and a family member retrieved the vehicle and drove it to the residence without failure. Several days later, the family member started the vehicle, and fuel started pouring out from underneath the vehicle. Due to the failure, the vehicle was towed back to the dealer and was diagnosed the vehicle with an O-ring failure inside the fuel injectors. The dealer repaired the O-ring, and the contact picked up the vehicle from the dealer. Soon after retrieving the vehicle, fuel started pouring out from under the vehicle at start-up. The vehicle was towed back to the dealer and remained with the dealer. The manufacturer was notified of the failure, and a claim was filed. The vehicle was not repaired. The failure mileage was approximately 68,000.

ELECTRICAL SYSTEM
I am writing to formally document a serious, recurring safety defect in ou 2026 Hyundai Tucson Hybrid, purchased less than a month ago. The vehicle has now exhibited multiple distinct dashboard warning faults related to the electronic shifter system, has left me stranded on more than one occasion, and has been sitting at Schomp Hyundai in [XXX] , for the second time, for over one week, with no resolution. The dealership has been unable — or unwilling — to properly diagnose the issue despite photographic documentation of the active fault warnings and the existence of Hyundai-issued Technical Service Bulletins directly addressing this problem. This letter serves as formal written notice pursuant to Colorado's Lemon Law (C.R.S. § 42-10-101 et seq. Since taking delivery, I have experienced multiple occurrences of two distinct dashboard fault warnings on this vehicle. Both have been photographically documented with date-stamped images: • "Shifter System Malfunction! Service Immediately" — The vehicle became inoperable and could not shift gears, leaving me stranded. "PARK Malfunction. Engage parking brake when parking vehicle." — A secondary fault indicating failure of the electronic park system, creating a serious safety hazard. These faults are not related to any collision or external damage. They are pre-existing manufacturing defects that began occurring in the first week of purchase. Notably, this is a known and documented issue affecting Hyundai Tucson Hybrid models. Hyundai has issued Technical Service Bulletins TSB #21-AT-007H and TSB #21-AT-009H. I drove the vehicle approximately 8 times (including to and from the repair center) and have had the issue multiple times.I am formally requesting the following immediate actions: • Direct the dealership to perform a complete GDS historical DTC scan per TSB #21-AT-007H and #21-AT-009H and provide full written results.

Vehicle has failed to start with NO WARNING LIGHTS (completely blank infotainment screen) and no sounds when start button is pressed. Vehicle also completely shuts down when stopping in traffic and takes several attempts at restarting before the vehicle actually starts and able to move. This is a SEVERE LIFE THREATENING OR SERIOS INJURY SITUATION that Hyundai seems to have no interest in solving. Incidents have been video when safety is not an issue.
