NHTSA Complaint #11649300 — 2013 HYUNDAI SONATA

On [XXX], in Washington, D.C., my 2013 Hyundai Sonata experienced sudden engine failure, leaving the vehicle inoperable. My goodwill repair request was denied within 30 minutes, without a proper inspection of the rod bearings (a known failure point covered under the TXXI extended warranty) or the fuel pipe recall—a known issue that could pose a fire hazard. Hyundai cited suspected maintenance neglect, but I have documentation of regular synthetic oil changes. Despite having over 200,000 miles, a Firestone inspection from September 2024 confirmed the vehicle was in good condition prior to the failure. Additionally, Hyundai Theta II engines are widely known to suffer from excessive oil consumption, a defect that can lead to premature engine failure even in well-maintained vehicles. Hyundai has replaced engines in vehicles with similar mileage under the same extended warranty, yet in this case, no proper inspection was conducted before denial. Safety Concerns: The fuel pipe recall was not inspected, raising concerns about whether unresolved recall defects are leading to engine failures or fire risks. The airbag clock spring, covered under Hyundai’s TXXA extended warranty, was not inspected, despite the airbag light being illuminated, potentially affecting airbag deployment in a crash. The vehicle failed without warning lights or error messages, creating an unsafe situation. Hyundai’s failure to inspect recall-related issues before denying repairs could impact other affected vehicles on the road. I request that the NHTSA: Ensure Hyundai properly inspects recall-related components before denying repairs. Investigate whether Hyundai is improperly denying warranty and recall-related repairs, even in cases where similar vehicles have received replacements. Determine if the unresolved fuel pipe recall and airbag clock spring defect pose broader safety risks. This issue has been reported to Hyundai corporate, but no proper inspection has been performed.
