ENGINE
My name is [XXX]. My husband, [XXX], and I purchased a 2017 Hyundai Tucson (VIN: [XXX]) from a Hyundai dealership in 2023 with 53,920 miles for our daughter to commute to school. The vehicle now has approximately 77,940 miles, and she is still attending school. Since purchasing the vehicle, we have consistently returned to the same Hyundai dealership for regular maintenance, trusting its professionals to keep the vehicle safe and reliable. While driving on the freeway, our daughter suddenly lost engine power. The vehicle slowed down and would no longer accelerate. Thankfully, she managed to exit the highway before it stopped completely. Highway patrol assisted her in moving the vehicle to the roadside. The Check Engine Light and oil-pressure warning light came on, the engine made a pronounced knocking sound, and it would no longer run. We believe these symptoms closely resemble the engine defect described in Hyundai's Recall 209 (NHTSA 21V-727), involving connecting-rod-bearing failure in certain 2017 Tucson vehicles. Hyundai Motor America denied our request for assistance, stating that our VIN is not included in the recall and that no warranty coverage applies. We respectfully question whether vehicles experiencing the same or substantially similar defect may have been excluded from the recall. We request a technical investigation into why our vehicle was excluded and whether its engine failure is related to the recalled defect. This was a serious safety concern, not merely a repair expense. Our daughter could have suffered a serious accident had she been unable to exit the freeway safely. We are grateful she escaped without injury. We respectfully request that Hyundai reconsider its decision, review the vehicle's maintenance and diagnostic records, and investigate the engine failure. If the failure is related to the recalled defect, we ask Hyundai to cover the cost of engine repair or replacement.

On [XXX], I purchased a 2017 Hyundai Tucson from DriveTime, located at 6400 Pensacola Boulevard, Pensacola, FL 32505. Within approximately nine days of purchase, the vehicle began experiencing serious mechanical problems, raising significant concerns about its safety and roadworthiness. On [XXX], the vehicle suffered a severe loss of acceleration and was unable to exceed approximately 30 mph. This sudden reduction in engine performance created a dangerous situation while driving, particularly when attempting to maintain normal traffic speeds. Following these issues, mechanical inspections revealed water inside the spark plug wells, a severely rusted ignition coil, and a failing catalytic converter. Firestone estimated the catalytic converter repair at approximately $5,000. The presence of water and corrosion raised concerns about possible pre-existing damage and whether the vehicle had been properly inspected before being sold. The vehicle remained in repair-related custody for approximately 29 days. Despite repeated communications with DriveTime, the mechanical problems were not satisfactorily resolved. DriveTime representatives informed me that a replacement vehicle had been approved. On [XXX], I returned to the dealership expecting a replacement but was informed that no suitable vehicle was available. I was left without transportation, and the dealership failed to provide a satisfactory resolution. As of October 21, 2026, I remain without a vehicle. I am requesting that NHTSA investigate the sudden loss of engine power, possible electrical or ignition system damage caused by moisture intrusion, and any similar safety complaints involving the 2017 Hyundai Tucson. My primary concern is that these mechanical failures could cause another driver to experience a dangerous loss of power while operating the vehicle, potentially resulting in a serious collision.

ENGINE, POWER TRAIN:AUTOMATIC TRANSMISSION
The contact owns a 2017 Hyundai Tucson. The contact stated that while driving at 65 MPH, the vehicle unexpectedly stalled and was unable to exceed 30 MPH. The contact pulled the vehicle over to the shoulder of the road, and the vehicle failed to restart. The vehicle was towed to the dealer, where it was diagnosed that the transmission failed and oil contaminated the catalytic converter, causing the catalytic converter to fail and require replacement. The transmission was repaired by the dealer, and the catalytic converter was replaced by an independent repair facility. The contact subsequently observed continued oil loss following the repairs. The vehicle was returned to the dealer, where it was diagnosed that the exhaust manifold headers failed and required replacement. The vehicle was not repaired. The contact requested and received a complete diagnostic report from the dealer. The failure mileage was approximately 90,502.

ELECTRICAL SYSTEM, ENGINE, VEHICLE SPEED CONTROL
While going down the highway at around 72 mph , my car went into limp mode. I was unable to accelerate, the brake and wheel locked. And then the engine light began flashing. The limp mode , non acceleration, and flashing engine light have happened twice before this instance. The first two times the pulled the P1326 knock sensor code and replaced it. Did the update, and sent me on my way saying it was fine. Now this most recent time (the 3rd time), the engine has failed. A CARFAX report says my car already had the engine replaced at 52k miles, meaning there’s 1 something internally wrong and 2 it’s still well within mileage warranty for another engine replacement. This car is extremely dangerous as it can literally stop in the middle of the highway. I went from 72 to about 15 mph in seconds, I was unable to get over or accelerate. It was terrifying. Now dealing with Hyundai - they don’t want to take fault.

ENGINE
Failed Component: Engine assembly / internal powertrain (specifically, a connecting rod bearing failure in cylinder #2 causing severe engine knocking and risk of mechanical seizure). The vehicle is available for inspection, the complete vehicle and affected engine assembly are intact and available for inspection upon request at CMA's Hyundai of Lexington Park: [XXX] Safety Risk: A rod bearing failure causes violent engine knocking, severe loss of engine power, and eventual engine seizure or stalling while driving. Losing propulsion unexpectedly—especially at highway speeds or in heavy traffic—creates an immediate collision risk for the vehicle occupants and surrounding traffic due to sudden loss of power, power steering, and power brake assistance. The issue was formally diagnosed and confirmed by an authorized Hyundai dealership service department. The technician performed a physical diagnostic evaluation and officially documented a knocking condition resulting from a connecting rod bearing failure in cylinder #2. Symptoms & Timeline: Initial engine knocking noises first appeared on XXX. The vehicle was previously updated with Hyundai's Knock Sensor Detection System (KSDS) Product Improvement Campaign, which is intended to detect excessive vibration from rod bearing wear prior to catastrophic failure. No check engine light illumination occurred or and type of indication from the vehicle there was something wrong other than the knocking noises.

I am reporting a suspected safety defect involving my daughter's 2017 Hyundai Tucson, VIN [XXX], with approximately 77,940 miles. The vehicle experienced an engine failure beginning with the illumination of the oil-pressure warning light and Check Engine Light, followed by a pronounced engine knocking noise. The vehicle subsequently could not continue running. The vehicle was inspected by a Hyundai dealership, which diagnosed an engine failure. I am aware of Hyundai Safety Recall 209 / NHTSA Recall 21V-727 involving certain 2017 Hyundai Tucson vehicles equipped with the 2.0-liter Nu GDI engine. Hyundai's recall documentation identifies premature connecting-rod-bearing wear and specifically identifies abnormal engine knocking and illumination of the oil-pressure warning light as symptoms that can precede engine damage and stalling. My daughter's vehicle experienced these same symptoms. Hyundai has informed us that this particular VIN is not included in Recall 209 and Hyundai Motor America has denied our request for assistance. I am therefore asking NHTSA to review this complaint as a potential safety defect and determine whether there may be additional 2017 Tucson vehicles outside the current Recall 209 population experiencing the same or substantially similar engine failure. I am not claiming that the vehicle is definitively covered by Recall 209. Rather, I am asking NHTSA to investigate whether the exclusion of this vehicle is appropriate given the similarity between the actual failure symptoms and the defect identified in Recall 209. I can provide the dealership's diagnostic documentation, Hyundai Motor America's denial, photographs, maintenance records, and other supporting information upon request. Vehicle: 2017 Hyundai Tucson, VIN: [XXX], Mileage: Approximately 77,940 miles Failure: Engine knocking, oil-pressure warning light, Check Engine Light, engine failure/stalling Related Recall: Hyundai Recall 209 / NHTSA 21V-727.

I have a 2017 Hyundai Tucson with a 1.6 turbo engine, and I have been experiencing massive oil consumption. Oil is coming out of the tail pipe with occasional big puff of smoke out of the tailpipe. Skipping and hesitation during acceleration, rough cold start, I have previously had the check engine light on with a multiple misfire code. I changed the plugs and the coils, and it did not resolve the problems. I then took it to the mechanic, and he told me that the car has to go to Hyundai because these are known problems with my particular motor. I took it to Balise Hyundai in Hyannis Mass. and was told that they know about these motor issues but could not help me because the engine light was not on.' If the light comes on, then bring it back and we will check it out'.I was then told that any work performed would be my responsibility to pay for it out of my pocket. If it a known problem by Hyundai, then I think that a recall or something should be posted so customers are not stuck with a very big service bill. Any help to get my vehicle running the way it was designed to would be greatly appreciated. Apparently, there are no recalls or campaigns about these issues on my vehicle even though they are well known to Hyundai

FUEL/PROPULSION SYSTEM, ENGINE, POWER TRAIN
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.
