Having problems with your Kia Soul’s trunk latch can be incredibly annoying, especially when it prevents you from accessing your cargo or leaves the trunk unexpectedly open.
These issues can interrupt your day, pose security risks, and even affect your vehicle’s performance. Here, we break down common trunk latch issues that Kia Soul owners face and offer practical solutions so you can get your car back to functioning smoothly.
1. Stuck Trunk: The Trouble of a Latch That Won’t Release
One of the most common complaints among Kia Soul owners is that the trunk latch won’t open when needed. Whether using the key fob, the interior release button, or the external handle, owners report that the latch remains unresponsive.
Sometimes, there’s no response at all, while in other cases, you might hear a faint clicking sound, but the latch doesn’t release.
This issue seems particularly common in first-generation Kia Souls from 2010 to 2013, but it’s also affected some second-generation vehicles.
Typically, the problem comes from a faulty actuator motor, which controls the latch’s release function. Over time, this small motor can wear out or develop electrical issues that stop it from working.
Damaged or corroded wiring may also block the electrical signal that the actuator relies on to release the latch. In older vehicles, parts of the latch mechanism may stick or fail to engage correctly, especially in extreme temperatures.
For example, owners of the 2011 and 2012 Kia Souls have reported that the trunk unexpectedly refused to open without warning, and cold weather seems to worsen the problem, suggesting that temperature may affect the latch or actuator.
To address this issue, replacing the trunk latch actuator is often necessary. Accessing it involves removing some interior paneling, after which a new actuator can be installed.
It’s also wise to check for any damaged or corroded wiring and clean and lubricate the latch mechanism with an automotive-grade lubricant to prevent future issues. Regular maintenance can often keep the latch from sticking, prolonging its lifespan.
2. Latch Won’t Lock: A Hassle of a Trunk That Won’t Stay Shut
Another common problem some Kia Soul owners encounter is that their trunk won’t latch when they try to close it. This issue leaves the trunk open or slightly ajar, often triggering warning lights on the dashboard and preventing the vehicle’s security system from activating correctly.
In some cases, the trunk might even pop open while driving, exposing the contents to the road and creating a safety hazard.
Misalignment of the striker plate is often the root of this issue. The striker plate is the part the latch catches onto, and if it’s even slightly out of alignment, the latch can’t properly engage.
Misalignment may result from normal wear and tear, minor impacts, or factory settings shifting over time. Also, if the latch’s internal components are broken or worn or debris has become lodged in the latch, it may prevent the trunk from locking securely.
For example, some 2010 Kia Soul drivers reported needing to slam the trunk forcefully to get it to latch, which suggests an alignment problem.
Drivers of 2013 models mentioned instances where the trunk would pop open unexpectedly while driving, leading to concerns about safety and security.
Adjusting the striker plate is usually the first step to fixing this. You can typically restore proper closure by loosening the mounting bolts and repositioning the striker to perfectly align with the latch.
If parts inside the latch are worn out, replacing the entire assembly might be necessary. Regular cleaning of the latch mechanism can prevent debris from obstructing the lock, keeping the trunk secure and functional.
3. Unresponsive Exterior Trunk Button: When the Release Switch Fails
For some second-generation Kia Souls (2012–2016), owners find the trunk release button on the exterior handle fails to work.
This can be inconvenient, forcing owners to rely on the key fob, the interior release, or even access the trunk from inside the vehicle. This issue is more frequently reported in newer models, likely due to design changes in the handle mechanism.
A malfunctioning exterior trunk button is usually due to a failing release switch. Over time, the switch may wear out, or moisture can seep in, especially in regions with frequent rain or where car washes are used regularly.
Damaged wiring or poor connections can prevent the switch from activating the actuator as needed. In areas with harsh weather, corrosion in the electrical contacts can further complicate matters.
Some 2014 Kia Soul owners report the button becoming unresponsive, leading to costly handle replacements. Owners of 2015 models mention that the issue can worsen after heavy rain or car washes, suggesting water is seeping into the switch area.
To resolve this issue, the faulty release switch is usually necessary to replace. Kia now provides updated parts with improved moisture resistance. Ensuring gaskets and seals around the switch are in good shape can help prevent further moisture issues.
In some cases, cleaning the electrical contacts with a suitable cleaner can restore temporary function, but this is not a long-term fix. Checking for signs of damage or corrosion in the wiring is essential.
4. Cold Weather Problems: When the Latch Freezes
Cold weather can present unique challenges, as some Kia Soul owners have found that their trunk latch becomes entirely inoperable in freezing conditions.
While the latch may work fine in warmer weather, it can become a recurring issue in winter, especially in colder climates like the northern United States and Canada.
The main cause is moisture entering the latch mechanism and freezing, preventing parts from moving. Water can seep into the latch through worn seals or weatherstripping, and inadequate lubrication can worsen the problem, as some lubricants become less effective at low temperatures.
Many 2013 and 2016 model drivers in colder areas report that their trunks are unusable until they warm up. Some drivers have resorted to pouring warm water over the latch to melt the ice temporarily.
A silicone-based lubricant designed to work in low temperatures can help prevent freezing. Replacing any worn weatherstripping or seals will also keep moisture out.
Keeping the latch area clean and debris-free can improve sealing, while a trunk cover can help protect the latch from snow and ice when parked outdoors.
5. Interior Trunk Release Button Fails: When the Inside Button Becomes Unresponsive
For some newer models from 2014 to 2019, owners found the interior trunk release button stopped working, forcing them to rely on other methods to open the trunk.
This issue is often due to a malfunctioning release button, a blown fuse, or a software glitch within the vehicle’s body control module (BCM), which can occur after battery replacements or other electrical work.
For example, owners of the 2015 Kia Soul mention the button failing to respond intermittently, sometimes fixing itself after a vehicle restart. Sometimes, a system reset or BCM software update may be required.
Replacing the release button can restore normal function if the release button is the issue. Checking for blown fuses related to the trunk release circuit is a simple and often effective fix.
If the issue stems from software, having the BCM reprogrammed or updated by a dealer can help, and disconnecting the battery for a few minutes may reset the system as a temporary solution.
6. Broken Trunk Handle: When the Exterior Handle Snaps Off
In some cases, particularly with earlier models (2010–2013), the exterior trunk handle snaps off, making it impossible to open the trunk from the outside.
The handle assembly includes plastic components that can become brittle over time, especially when exposed to temperature extremes and sunlight. Applying too much force, especially if the latch is stiff, can cause the handle to break.
Many 2011 Kia Soul drivers have shared instances where the handle broke with little warning, sometimes leaving them without access to the trunk.
The cost of a replacement handle can be significant, and without addressing any underlying issue, a new handle might break under similar conditions.
Replacing the broken handle with an updated or reinforced model is necessary. Some aftermarket handles use more robust materials to withstand daily use.
Addressing any stiffness in the latch mechanism itself is essential to avoid needing excessive force to open the trunk. Regular maintenance can prevent stiffness and keep the latch functioning correctly.
7. False “Trunk Open” Warnings: When Sensors Malfunction
Some Kia Soul drivers have noticed a “trunk open” warning light on the dashboard, even when the trunk is fully closed.
This false alert can prevent the vehicle from locking correctly, as the system believes the trunk is open. Sometimes, the interior lights stay on, which can drain the battery.
A faulty trunk sensor usually causes this issue by mistakenly signaling the system that the trunk is open. Wiring issues or BCM faults can also trigger this warning.
Many 2016 model owners report the warning light flashing intermittently, often during damp conditions, suggesting moisture might affect the sensor or wiring.
Replacing the trunk sensor usually resolves the problem. Technicians can use diagnostic tools to identify error codes and check for BCM faults.
Regular inspection and maintenance of the sensor and wiring can help prevent these alerts from appearing. Improving sealing around the sensor and wiring can offer a lasting solution if moisture is recurring.
Final Thoughts
Dealing with trunk latch issues in your Kia Soul can be a hassle, but knowing the causes and solutions can make them easier to handle.
Whether it’s a quick fix, such as cleaning and lubricating the latch, or a more complex repair involving the actuator or handle, addressing these problems early can help maintain your vehicle’s convenience and security.
