🔍 Condition & Functionality

• Overall Status: Used – Good cosmetic and mechanical condition.
• Testing: 100% Bench tested and fully function verified under specialized high-voltage hybrid load simulations prior to vehicle dismantling. The internal motor-generator armature spins smoothly, three-phase power insulation checks register clean, engine startup cranking torque outputs hit peak factory target specs, and regenerative braking charge capture efficiency tracks flawlessly.
• Cosmetic Notes: Normal light wear, typical under-hood engine room road dust film, minor oxidation traces on raw cast alloy housing paths, or minor mounting ear blemish markers from standard deployment. The heavy-duty multi-groove pulley spun rotates freely, and the primary high-voltage terminal block and control low-voltage signal plug sockets are clean and entirely intact. Unit is completely verified free from internal winding shorts, phase wire trace degradation, bearing howling noises, or internal rotor wobble.

⚠️ Fitment & Compatibility

• Compatible Models: Direct factory interchange replacement fitment for corresponding models matching this mechanical, structural, and electrical high-voltage hybrid blueprint, explicitly including:
  • Kia Optima Hybrid (TF Generation Platforms / 2011-2016 Model Years running matching HSG specs)
  • Cross-Vehicle Applications: Due to platform engine and shared drivetrain architecture utilization across Kia/Hyundai hybrid lines, this hardware profile matches matching 2.4L configurations of corresponding model platforms (explicitly including variants of the **Hyundai Sonata Hybrid 2011-2015** — please cross-reference your original unit\'s precise part number stamps first to ensure an exact engineering match).
• Buyer Responsibility: Please verify your original unit\'s precise part stickers, part numbers, and plug layouts match our listing photos completely before purchasing. High-voltage powertrain electronic architectures can alter wiring paths and mounting ears heavily across model year thresholds and hybrid system generational splits (will NOT fit standard non-hybrid gasoline configurations).
• Verification: Compare your existing plug shapes, housing contours, and terminal pin arrays directly to our listing photos to guarantee option matching. Note: This handles critical high-voltage engine startup, regenerative charging parameters, and hybrid powertrain vehicle communication networks. Replacing a Hybrid Starter Generator (HSG) component on modern platforms strictly requires professional automotive technician handling. It strictly requires specialized diagnostic scan tool initialization adjustments, belt tension sensor tracking calibrations, or hybrid system fault resetting parameters to integrate successfully with your main Hybrid Control Engine ECU / Inverter network and cleanly eliminate active dashboard warning trouble codes. This part is NOT simple plug-and-play.

📦 What’s Included

• (1) OEM Kia/Hyundai Hybrid Starter Generator (HSG) Alternator Assembly with pre-installed pulley wheel as pictured. Interconnecting engine main wire harnesses, separate high-voltage cabling lines, power inverter modules, accessory drive belts, belt tensioner hardware, or main hybrid traction battery packs are not included.

🚚 Shipping & Returns

• Handling: Packaged securely inside a clean, robust shipping box heavily wrapped in thick defensive anti-static cushion wrap overlays to safeguard the heavy-duty drive hub, terminal terminal covers, and protect alloy casting lines from shifting or structural crushing damage during transit.
• Return Policy: 30-day (one month) return window. Buyer is responsible for return shipping costs.
• How to Return: Please message us directly via before opening a case so we can assist you quickly.

🛡️ Warranty & Support

• Coverage: Includes a 1-month replacement/refund warranty on the part structure itself.
• Exclusions: Labor, mechanic engine bay component disassembly teardown workshop fees, high-voltage safety diagnostic checks, inverter matching parameters, drive belt or tensioner replacement items, or diagnostic tool trouble code resetting costs are strictly non-refundable. Component damage tracking failures caused by improper high-voltage line phase terminal shorting or improper belt alignment configurations handling during installation are explicitly excluded from tracking warranty claims.
• Customer Service: Your satisfaction is our top priority. Contact us anytime for a fast resolution!
