A-Premium Trunk Latch for Hyundai Sonata (Right Rear 2009–2015) — Direct-Fit Rear Lock Actuator, OEM-Style Durability

If the trunk on your Hyundai Sonata won’t latch, makes clicking noises, or fails to lock electrically, a worn lock actuator is often the cause. This A-Premium rear trunk latch assembly is engineered as a direct-fit replacement for select Sonata model years, combining robust plastic housings and reinforced metal components to resist wear and maintain fitment. It ships as a complete actuator unit for the rear tailgate, designed to reinstall using OEM mounting points and wiring harness connections.

Which Hyundai models and engines will this trunk latch fit?

This actuator is intended for specific Sonata sedans produced across several model years. Confirm fitment against your vehicle’s year and engine to ensure compatibility before purchase, since the same nameplate may use different latch assemblies across trims.

• Compatible makes: Hyundai Sonata sedan
• Model years: 2009–2015 for 2.4L L4; 2011–2014 for 2.0L L4; 2009–2010 for 3.3L V6

• Reference part number(s): 81230-3Q000 / 812303Q000 — verify against your VIN

How does this rear trunk lock actuator improve trunk operation?

Replacing a failing actuator restores smooth locking and unlocking of the trunk and eliminates intermittent electronic or mechanical failures. The unit is built to reduce deformation and tolerate repeated operation, improving long-term reliability compared with a worn original component.

• Replaces faulty motor/gear assembly that causes non-locking trunks
• Durable plastic housing and high-density metal parts resist breakage
• Designed to mate with factory wiring and mounting points for straightforward swap
• Helps stop clicking sounds and inconsistent latch engagement

What should I expect during installation and fitment checks?

Installation generally involves removing interior trunk trim, unplugging the factory connector, swapping the old actuator for the new unit, and reassembling trim. Basic hand tools are usually sufficient; however, check the reference numbers and connector shape to confirm correct fitment before beginning work.

• Requires access to rear trunk interior and basic tools (screwdriver, socket set)
• Unplug factory wiring harness, unbolt old actuator, bolt in new actuator, reconnect wiring
• Confirm part numbers 81230-3Q000 / 812303Q000 match your original before ordering
• Test lock/unlock with key fob and interior switch before reassembling trim panels
