Smart Automatic Soft-Close Door Latch with Anti-Pinch for Tesla Model 3/Y

Upgrade your Tesla with the Smart Automatic Soft-Close Door Latch with Anti-Pinch for Tesla Model 3/Y, delivering a smooth, quiet door close with smart suction technology. Its compact dual-motor design, IP67 protection, and built-in anti-pinch safety enhance comfort, reduce door wear, and ensure reliable daily performance.

Key Features:

Next-Generation Integrated Dual-Motor Module Design: This system features a fully integrated dual-motor module that combines logic control and power drive into one compact unit. Unlike conventional soft-close kits that rely on bulky external control boxes and complex wiring layouts, this design minimizes installation clutter while improving system stability. The compact architecture fits cleanly inside the door cavity, preserving factory aesthetics and ensuring long-term reliability without unnecessary components.

IP67-Rated Protection: To ensure durability in real-world driving conditions, the unit uses industrial-grade sealant-fixed wiring instead of standard plug connectors. The harness is permanently bonded to the module, creating an IP67-rated seal that resists moisture, dust, vibration, and temperature fluctuations. This protection level is ideal for long-term use in varied climates, including rain, snow, and high-humidity environments.

Precision 10mm Micro-Stroke Smart Suction Technology: Engineered with a refined 10mm micro-stroke suction mechanism, the system gently pulls the door shut during the final stage of closure. This intelligent stroke design eliminates the harsh “metallic clang” common with traditional door latches, delivering a closure that is up to 70% quieter. The result is a smooth, refined closing action that feels consistent with high-end luxury vehicles.

Optimized Power Performance: The soft-close system is precision-tuned to operate flawlessly within Tesla’s electrical range of 9V to 15V. It delivers a strong and consistent suction force while maintaining ultra-low power consumption. This optimized efficiency ensures reliable performance without placing additional strain on the vehicle’s battery, making it suitable for daily use without affecting energy management or vehicle electronics.

Intelligent Anti-Pinch Safety Monitoring System: Safety is built into every closing action. Integrated smart sensors continuously monitor the 10mm suction stroke in real time. If resistance or obstruction is detected, the system immediately stops operation to prevent injury or damage. This advanced anti-pinch protection ensures safe operation for passengers, children, and pets while maintaining smooth and controlled door closure.

 Enhanced Cabin Comfort and Reduced Wear Over Time: By eliminating repeated door slams, the soft-close system helps reduce long-term wear on door hinges, latches, seals, and interior trim. This not only improves daily comfort but also contributes to preserving your vehicle’s condition over time. 

Installation Overview

Step 1: Remove Door Panel
Remove the screws of the speaker and the interior panel first.

Step 2: Remove the glass from the car door
Be careful when removing the glass.

Step 3: Remove the plastic cover plate of the interior
Disconnect the single plug-and-play harness and screws.

Step 4: Install the new suction lock
Remove the original car door lock, install a new one, and test it. (The self-priming lock needs to be fixed with the screws we provide!)

Frequently Asked Questions
01. Why is an "Integrated" module better than one with an external box?
External control boxes require extra mounting space and create more "failure points" where wires can tug or leak. Our integrated design is more durable, easier to install, and eliminates the risk of internal door rattles.

02. Is the sealant-fixed harness permanent?
Yes. We use automotive sealant to fix the wiring harness to prevent it from falling off due to road vibrations or "backing out" due to water ingress. This ensures a lifetime of stable electrical contact.

03. Will this draw too much current from my 12V/16V battery?
Not at all. The system is highly efficient, with a peak working current of less than 5A. It only draws power during the brief 1-2 second closing window and goes into a deep-sleep mode otherwise.
