What Causes an Electric Tailgate to Pop Open But Not Fully Open?

Here are the reasons why an electric tailgate may pop open but not fully open: 1. Latch Mechanism: Check if there are any other latch mechanisms inside the vehicle. If not, the issue may be with the remote control or the interior switch, requiring repair at a 4S shop. 2. Control Box Issue: The problem could lie with the control box, which serves as the 'computer' control center for the electric tailgate. If it malfunctions, it may fail to receive commands from the switch, preventing the tailgate from opening. Additionally, there might be faults in the power wires, control wires, or adapter wires, causing a loss of connection, which results in the tailgate having no power or signal and thus failing to open. Lastly, the support struts or springs may have broken or come loose, preventing the electric tailgate from opening.

I've encountered the issue of the electric tailgate popping but not opening several times. The most common cause is the latch mechanism getting stuck due to dust or rust inside, preventing the door lock motor from operating. Another possibility is insufficient pressure or oil leakage in the hydraulic struts, making them unable to lift the entire door. Listen for sounds—if the motor hums but can't push the door open, it's likely a mechanical issue. During repairs, I've also found many cases where oxidized wiring connectors in the tailgate cause poor contact, cutting power and resetting when opened. It's recommended to first clean any sand particles from the tracks and hinges, then apply lubricant to the latch hook. Avoid forcing it open yourself, as this can damage the wiring. It's safer to have a professional shop disassemble and adjust it.

My car had this issue too, mainly related to sensors or control modules. If the tailgate sensor gets muddy water or the magnet shifts, the system receives incorrect signals and automatically stops operation. Also, overloading the trunk and blocking the sensing area can trigger the anti-pinch function, causing it to pop open. Additionally, unstable battery voltage can cause the control module to crash. I once experienced system malfunction on a rainy day, and it recovered after opening and closing three times. Remember to keep the sensors clean, lock the car for ten minutes after parking to reset the system, and if that doesn't work, check the module codes and refresh the program.

The electric tailgate opening halfway and bouncing back is mostly due to physical obstructions. For example, if my parking space has a slope and the rear of the car is facing downward, the gravity is too strong for the struts to handle. In winter, rubber seals can freeze and harden, causing the door to get stuck. Additionally, improper operation is common, such as pressing the button before the unlocking process is complete, triggering the system's protection mechanism. The solutions are simple: clear debris from the tracks, ensure the vehicle is parked on level ground, and make sure the unlock light is on before opening the tailgate. Applying lubricant to the seals can improve performance in cold temperatures. If self-adjustment doesn’t work, have the gas struts' pressure professionally calibrated.

I deeply relate to this issue, where aging springs or motors are the main culprits. Especially in older vehicles, fatigued springs can't push the door open, and worn motor gears only provide a single thrust. Short circuits are also a hidden danger—I've seen cases where rats chewed through wires, causing the tailgate to repeatedly reboot. It's advisable to keep the trunk dry and moisture-free to prevent motor corrosion. You can perform a simple test: manually push the door while listening for abnormal noises; a creaking sound indicates it's time to replace the springs. Before replacement, disconnect the power for five minutes to rule out temporary faults. If the problem persists, the drive assembly needs servicing.

Electric tailgate failure usually stems from three aspects: latch, strut, and system settings. A deformed latch causes pin disengagement; leaking gas struts (like when my roof rack overload caused failure); or remote key signal interruption from excessive distance. Diagnosis is simple: first check for door gap obstructions, then listen for proper motor operation when activating the switch. I recommend resetting the tailgate to factory settings while updating body control software. Prevent frequent overloading in daily use, and apply silicone grease to hinges biannually for longevity.
