NHTSA Complaint #11718659 — 2015 HYUNDAI SONATA

This complaint concerns a repeat failure of both front CV axles on my 2015 Hyundai Sonata. The CV axles and boots were replaced by Gettel Hyundai of Charlotte County using OEM parts in November 2024. The same components failed again just 7,876 miles later in January 2026; requiring a second full replacement. A CV axle replaced with factory OEM parts by a certified Hyundai tech should not fail within 7,876 miles under normal driving conditions. This pattern of repeat failure indicates either * A defect in the OEM replacement parts supplied by Hyundai * An installation defect at the authorized dealership * An unresolved underlying mechanical condition that causes accelerated CV axle wear The rapid repeat failure represents a potential safety hazard. CV axle failure can result in sudden loss of drive power, difficulty controlling the vehicle, and in severe cases, wheel separation --all of which create dangerous conditions for the driver and others on the road. Chronological Timeline of Events: Nov 5, 2024 55,579 miles; both front CV axles replaced by authorized Hyundai dealership using OEM parts. Labor and parts performed per Hyundai standards. Jan 29, 2026 63,451 miles Same CV axles failed again. Second replacement performed at same authorized Hyundai dealership. Total repair cost $3227.16 paid out of pocket by me. Feb 16, 2026 Hyundai Motor America denied goodwill reimbursement request (Case #XXX), citing the malfunction being out of time in service of the vehicle. Reported to Hyundai Motor, their response did not address the repeated nature of failure, the short mileage interval, or the possibility of a defective OEM part or improper installation. I believe the NHTSA should be aware of this pattern and investigate other 2015 Hyundai Sonata owners have reported similar rapid repeat CV axle failures, which could indicate a systemic defect in either OEM parts or dealership repair procedures.
