NHTSA Complaint #11704643 — 2020 HYUNDAI ELANTRA

Subject: Abnormal Engine Failure – Hyundai Case #[XXX] I am filing this complaint regarding my Hyundai vehicle, which suffered catastrophic engine failure at approximately 150,000 miles. While the vehicle is outside the standard warranty, this type of failure is not consistent with normal use or expected durability. Hyundai Motor America has acknowledged receipt of my certified demand letter (Case #[XXX]) but has refused to provide coverage, instead directing me to pay for towing and diagnostic costs. This position is unacceptable given Hyundai’s history of abnormal engine defects and related settlements. Key points: • The failure is abnormal and consistent with systemic defects Hyundai has faced in prior litigation, including the Theta II and Lambda II engine defect class actions, which resulted in recalls and settlements covering millions of vehicles. • Hyundai has previously extended goodwill repairs and recall coverage for similar failures, even outside warranty periods. • Engine failure at this mileage presents a serious safety hazard, including risk of stalling, fire, or loss of power while driving. • Hyundai’s refusal to cover towing and diagnostic costs places an unfair burden on consumers and may violate consumer protection statutes. Requested Action: I request that the agency investigate Hyundai’s handling of abnormal engine failures, ensure compliance with consumer protection and safety laws, and require Hyundai to provide coverage or reimbursement for towing, diagnostic, and repair costs in cases where engine failure is abnormal and unsafe. Supporting Documentation: • Certified demand letter sent to Hyundai Motor America. • Hyundai’s written denial (Case #[XXX], dated December 11, 2025). • Vehicle mileage and details of engine failure.
