NHTSA Complaint #11679266 — 2018 HYUNDAI TUCSON

I am submitting this formal safety complaint regarding my 2018 Hyundai Tucson. The vehicle has 101,900 miles and has been well maintained. Recently, it began experiencing severe performance issues, including difficulty accelerating and consuming oil at an abnormal rate. The dealership diagnosed the problem as a failed catalytic converter with an estimated repair cost of over $8,000. While Hyundai has an active recall on the engine for this model year, they have stated that my specific problem is not covered, despite the fact that the catalytic converter failure appears to be directly related to the engine defect. The oil consumption and acceleration issues raise serious safety concerns, as the vehicle can lose power unexpectedly while driving. I am a teacher, a parent, and have one child with special needs. I have no other form of transportation and am still making payments on a car I cannot safely drive. Hyundai’s refusal to address this issue as part of the known recall leaves me with an unsafe and inoperable vehicle through no fault of my own. I believe this matter warrants further investigation by the NHTSA, as it suggests that related component failures stemming from the defective engine are not being adequately addressed, leaving owners at financial and safety risk. I respectfully request that the NHTSA investigate whether Hyundai is failing to address a known defect’s full scope and to take appropriate action to ensure the safety and fair treatment of affected consumers. Thank you for your attention to this matter.
