The Core Symptoms: "The high-pressure fuel pump is leaking internally. Raw gasoline is flooding into the engine oil crankcase, causing severe fuel dilution. The engine air filter is physically soaked in raw fuel and smells strongly of gasoline." My engine is always extremely hot after I have only went 15 mins away from home. Sometimes takes over two hours to cool down. The Safety Risk: "When attempting to accelerate, the vehicle experiences severe fuel starvation, causing the engine to bog down and act like it is going to stall in the middle of traffic, creating a severe crash hazard. Additionally, there is a loud 'popping' sound/mini-backfire upon turning the vehicle off due to unburnt fuel vapors, presenting a high risk of an underhood engine fire. I have only 83,000 miles on my car.

Subject: Formal Safety Complaint Regarding Steering Failure – 2017 Hyundai Tucson To Whom It May Concern, I am submitting this complaint to request that the National Highway Traffic Safety Administration (NHTSA) investigate a potentially serious safety defect involving the Motor-Driven Power Steering (MDPS) system in my 2017 Hyundai Tucson. I am the second owner of this vehicle. The vehicle currently has approximately 61,000 miles and remains within Hyundai's 10-Year/100,000-Mile Powertrain Warranty period applicable to subsequent owners. Approximately two years ago, the vehicle's engine was replaced under a Hyundai safety recall. Recently, I began experiencing intermittent steering problems in which the steering wheel becomes extremely difficult to turn and appears to momentarily jam or lock while driving. This condition significantly affects vehicle control and creates a serious safety hazard, particularly during turns, lane changes, or emergency maneuvers. I brought the vehicle to Advantage Hyundai in [XXX] for diagnosis. The dealership determined that the vehicle had a Motor Position Sensor Error (Diagnostic Trouble Code C2401) within the Motor-Driven Power Steering (MDPS) system. The dealership informed me that the repair is not covered under the vehicle's warranty and declined to repair it. The dealer also submitted a request to Hyundai for goodwill assistance (Prior Authorization No. XXX), but Hyundai denied that request. I subsequently contacted Hyundai National Consumer Affairs (Case No. XXX) seeking assistance. Unfortunately, Hyundai also denied my request despite the relatively low mileage and the serious safety implications of the steering malfunction. My concern extends beyond the cost of repair. A malfunction in the electronic power steering system that causes steering to bind, jam, or become difficult to control presents a significant risk of a crash, injury, or loss of life. Steering is one of the most critical safety INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am filing a safety complaint regarding my Hyundai vehicle after experiencing a sudden engine failure that appears consistent with known rod bearing and engine defects affecting certain Hyundai engines. While driving, my vehicle began making a knocking noise and shortly thereafter suffered catastrophic engine failure. The engine lost power and became inoperable, requiring the vehicle to be towed. This failure occurred without any prior indication that the engine was about to fail. My concern is that this type of engine failure creates a significant safety hazard because it can occur unexpectedly while driving, potentially causing a loss of power in traffic and increasing the risk of a crash. The dealership inspected the vehicle and engine but did not report excessive sludge buildup. I have provided available maintenance records showing that oil changes were performed during my ownership. Despite this, there appears to be disagreement regarding the cause of the failure. I am aware of reports involving rod bearing and engine failures in similar Hyundai vehicles and believe NHTSA should investigate whether this failure is related to a broader manufacturing or design defect. The cost of replacing the engine is substantial, and consumers may be placed at risk if these failures occur while vehicles are being operated on public roads. I am requesting that NHTSA review this issue and determine whether additional investigation, recalls, or other corrective actions are warranted.

2017 Hyundai Tucson | VIN: [XXX] | Mileage: 75,000 I have owned this vehicle for approximately five years and have experienced severe excessive oil consumption for the past two to three years. The issue was first discovered when the vehicle entered protective mode due to critically low oil levels despite a routine oil change having been performed only a few months prior. I am currently required to add approximately one quart of oil every month to maintain safe operating levels. I visited an authorized Hyundai dealership to have an oil consumption test performed. The dealership informed me that if the test confirmed excessive consumption, I would be required to pay out of pocket for an engine replacement. I declined, as Hyundai Motor America has publicly acknowledged this exact defect in the 2017 Tucson through NHTSA Recall 21V727000, multiple Technical Service Bulletins, and a class action settlement covering 2014-2021 Tucson vehicles with the Nu 2.0-liter GDI engine. My VIN was found ineligible on the class action settlement website despite the acknowledged defect. Hyundai has admitted this engine suffers from premature bearing wear, excessive oil consumption, and risk of engine failure and fire. I am requesting NHTSA investigate why my VIN falls outside current recall coverage despite presenting identical symptoms to affected vehicles.
