Why can't the Haval F7 trunk be opened with the remote control?

[DiCollin]

Reasons why the Haval F7 trunk cannot be opened with the remote control: insufficient battery power or improper operation. The trunk can be opened using the remote key, or inside the car via the opening button on the driver's side door, and outside the car by inserting the key into the trunk lock. Below is an introduction to the model: The Haval F7 is positioned as a compact SUV, with a body weight of 1610KG. The body dimensions are 4620mm in length, 1846mm in width, and 1690mm in height, with a wheelbase of 2725mm. It adopts Haval's latest family design style, featuring a large hexagonal grille and eagle-eye-shaped LED headlights on the front face, paired with an exaggerated and dynamic front bumper, presenting a sharp and aggressive appearance.

I've been driving my Haval F7 for two years now and have also encountered the issue of the trunk not opening with the remote. That time, I was rushing to send my child to school and was sweating with anxiety. Later, I realized the remote key was too far from the car and didn't respond; I had to get closer and press it. Another time, the trunk was jammed with too much clutter, and clearing it out solved the problem. If neither of these situations applies, it might be that the key battery is running low—try replacing the coin cell. Also, check the central control settings to see if the electric tailgate function was accidentally turned off; you can find this in the vehicle settings tab on the car's screen. However, last week my neighbor's car had an even weirder issue—the lock was stuck with tree sap, and it took spraying WD-40 to fix it. If all else fails, try holding the unlock button on the key for 5 seconds to force unlock. If it still doesn't open, then it's time to visit the 4S店 to check the signal module.

Last time I helped a friend deal with a Haval F7 trunk malfunction, I realized such issues actually follow certain patterns. The most common are mechanical failures, like aging and jamming of the trunk lock block spring, which is especially noticeable in cold weather. Inserting the mechanical key into the trunk lock and turning it twice—if it opens, it means the wiring is fine. If the mechanical key doesn’t work either, it’s most likely due to rust in the lock block assembly, which needs replacement. Also, a reminder: when washing the car, avoid spraying water directly at the license plate frame, as the tailgate wiring harness near the license plate light is prone to water seepage and short circuits. Last winter, I repaired three cars of the same model, all caused by cracked waterproof sleeves leading to harness oxidation, which prevented signals from reaching the actuators. Those who’ve modified their cars with power tailgates should be extra cautious, as the added relay modules are the most likely to malfunction.

In the car enthusiast circle, the Haval F7 is often called the 'Smart God Car,' but the trunk malfunction issue can be really frustrating. I remember one time during a road trip at a service area, the trunk just wouldn't open no matter what, and the mobile app control failed too. Later, I found out it was accidentally triggered into anti-theft mode—holding the unlock button on the key fob for ten seconds fixed it. My advice: first check the dashboard for any trunk opening icon prompts; if there’s a red cross symbol, it’s likely signal interference. Nearby high-voltage lines or signal towers can block wireless communication. Here’s a pro tip: sit in the driver’s seat, press and hold the menu button on the steering wheel with your left hand, and quickly press the trunk button three times with your right hand—this forces a reboot of the electronic tailgate module. For those who’ve modified the circuit, be extra careful. About 70% of friends who spent thousands installing an electric tailgate ended up needing repairs.

The electric tailgate system of the Haval F7 consists of a body control module, an actuator motor, and an angle sensor. When the remote control fails to open it, first eliminate basic factors: check if the key battery voltage is below 2.8V, and observe whether there is a clicking sound from the tailgate lock motor when using the remote. If there is motor sound but it doesn't open, it's due to the motor gear set jamming or the drive rod disengaging; if there is no sound at all, focus on checking the wiring. Use a multimeter to test whether the tailgate wiring harness connector is powered. This connector is located inside the left decorative panel of the tailgate. Common fault points include fatigue fracture of the cable at the tailgate hinge or poor contact of the BCM module pins. A car repaired last week had a short circuit in the lift switch causing the system to protectively power off, requiring disconnecting the negative battery terminal for ten minutes to reset. It is recommended to clean the latch groove monthly, as dust accumulation can cause the micro switch to fail.

Veteran drivers recommend checking these three key points first: First, check if the trunk lock button was accidentally pressed inside the car—it's located on the left panel of the driver's seat. Second, note that most car models disable the remote trunk opening function when the engine is running; you'll need to turn off the engine and try again. Third, an easily overlooked issue is the overload alarm. If the trunk is packed with too many heavy items exceeding the set weight limit, the electric latch will trigger overload protection. Last year, my F7 had this problem when the trunk mat was pressed down and jammed the stopper. After long-term parking, the control module might also freeze; disconnecting the negative battery cable for five minutes and reconnecting it usually solves the issue. During maintenance, remember to ask the technician to apply some white grease to the trunk latch tongue to prevent both noise and sticking.
