Even compared to discounted dealer pricing ($519-541), our NEW Korea Direct price is 4-8% lower with faster international shipping.4DDP Shipping Included - No Customs FeesAll US import duties and taxes prepaid (DDP - Delivered Duty Paid).

Send your 17-digit VIN via eBay messages and we will verify fitment within 12 hours - completely free. We confirm trim, model year, and HEV badge before you commit to purchase.FREQUENTLY ASKED QUESTIONSQ1. How do I confirm my Elantra is the Hybrid (HEV) model?Look for the 'HEV' or 'Hybrid' badge on the rear trunk lid or driver-side fender. Check your owner manual cover - it should explicitly state 'Hybrid'. Your VIN starts with 'KMHL' for Hyundai Korea-built Elantra. Send your 17-digit VIN via eBay messages for free verification within 12 hours.Q2. Does this fit 2024 or 2025 Elantra Hybrid?NO. The 2024-2025 model year (CN7 PE facelift) uses successor part number 37513-BY100, which is a separate listing. This part (37513-BY000) fits 2021-2023 model year ONLY (per NHTSA Recall 23V-589 production date 12/15/2020 - 07/29/2023).Q3. Is this the 12V battery sensor or the High Voltage battery BMS?This is the HIGH VOLTAGE traction battery BMS (mounted under the rear seat in the hybrid battery pack assembly). It is NOT the 12V auxiliary battery sensor or 12V battery management module - those use entirely different part numbers (37180 series).Q4. Does this require programming after installation?YES. This module REQUIRES dealer programming/coding with Hyundai GDS-VCI scan tool after installation. Buyer is responsible for ensuring access to a Hyundai dealer or independent shop with GDS-VCI / J2534 capability. Programming cost typically $100-200 at dealer (NOT included in our price). This is industry standard for all ECU components.Q5. What is your return policy for this BMS?Returns accepted within 30 days ONLY if the module is unused, sealed, and not programmed. Once installed or programmed, the module is non-returnable per industry standard for ECU components. Defective on arrival cases are handled separately with seller approval - please contact us within 48 hours of delivery.Q6. Why is your price lower than the US dealer?We source directly from authorized Hyundai Mobis dealers in Korea (the country where this part is manufactured). By eliminating the multi-tier US distribution markup (MSRP $768.08 US dealer cost), we can offer the identical NEW genuine OEM part at $499 with FedEx Priority shipping included. Same factory, same quality, same warranty - just shorter supply chain. Shipping & ReturnsHandling Time: We ship within 1-3 business days after cleared payment.Estimated Delivery: All packages are shipped securely with international tracking via FedEx International Priority (2-4 business days).
