Problems with the Peugeot 5008’s automatic tailgate often have three causes. The battery voltage is too low. The tailgate is experiencing mechanical resistance. A fault in the sensors or wiring is also often a factor. The tailgate may unlock but then fail to swing upwards. Such complaints are especially noticeable in cold weather. On the page about Peugeot 5008 problems you will find more points to look out for with this model. A few targeted checks will often show where the fault lies.
Why won’t the Peugeot 5008’s automatic tailgate open?
An electric tailgate needs more than a working lock. After unlocking, the electric drive, sensors and control unit work together. If there is resistance or an abnormal signal, the system stops opening for safety reasons.
That explains why you may sometimes hear the lock click while the tailgate remains closed. A double beep or a tailgate that stops early also points to a blockage. The system prevents the motor or tailgate from being damaged.
Common causes include:
- Low voltage from the 12-volt battery.
- Ice, dirt or deformed seals around the tailgate.
- A lock that opens too heavily or is not adjusted correctly.
- Rubber bump stops set too far inwards.
- A disrupted signal from a sensor or switch.
- Damaged wiring at the tailgate or hinges.
- A temporary safety lockout after frequent opening and closing.
When diagnosing the fault, pay close attention to clicks, beeps, silence and movement. A clear click with the tailgate staying still suggests resistance around the lock or tailgate. Complete silence points to an electrical problem, low battery voltage or a faulty switch.
‘ Uneven or major adjustments lead to a tailgate that closes crookedly or leaks. ’
Why does the tailgate unlock without swinging open?
The tailgate unlocks, but does not rise. The drive then does not receive enough force. A weak battery sometimes supplies enough voltage to the lock. The electric motors receive too little voltage. Other electrical functions do not necessarily fail at the same time.
Mechanical adjustment also plays a role. The rubber bump stops press the closed tailgate lightly against the lock. Bump stops set too far inwards hold the tailgate in place. After unlocking, the tailgate does not come free enough. The drive then has to overcome extra resistance straight away.
A small adjustment of the rubber bump stops or the closing position helps according to some owners. Adjust the rubber bump stops and closing position carefully. Change both sides evenly and only in small steps. Uneven or major adjustments lead to a tailgate that closes crookedly or leaks.
Is the tailgate reliable in cold weather?
Cold weather can make existing weak points more noticeable. A battery delivers less power at low temperatures, while the electric tailgate demands a lot of current. In mild weather the battery may still seem usable. In winter it sometimes supplies insufficient voltage.
Moisture and ice around the lock, seals and tailgate edges create extra resistance. Seals also become less supple in the cold. The tailgate then unlocks without moving upwards immediately. Sometimes the tailgate stops halfway.
That does not mean every Peugeot 5008 tailgate is unreliable in cold weather. If problems keep recurring in low temperatures, check the battery, adjustment and mechanical parts. If the fault keeps returning, simply defrosting it is not a lasting solution.
How to reduce winter problems with the Peugeot 5008 tailgate
- Remove snow and ice before operating the tailgate.
- Clean the lock and the edges around the tailgate.
- Check that the seals are not frozen in place.
- Have the condition of the 12-volt battery measured.
- Do not operate the tailgate repeatedly if it is blocked.
Do not use excessive force to pull a frozen tailgate free. This can damage the seals, drive or hinges. First defrost the relevant parts and then try operating it again.
How do you repair the automatic tailgate?
Start with simple checks. Only then should parts be replaced. Voltage, dirt or incorrect adjustment cause many faults. A defective motor is not immediately the cause. Work calmly and do not force the tailgate if there is clear resistance.
Check the space around the tailgate. Look for blocking ice, dirt, luggage and deformed seals.
Test all operating buttons. Test the button on the tailgate, the controls in the car and the remote control. Also test the hands-free sensor. This applies to a Peugeot 5008 with this function.
Open and close the tailgate fully by hand if there is little resistance. This often restores the system’s position recognition after a battery change, charging or a temporary fault.
Check the battery voltage. Have the resting voltage measured. Also have the battery condition measured under load.
Inspect the lock and the rubber bump stops. Look for misalignment, heavy unlocking and signs of wear from contact or friction.
Wait about ten minutes after repeated use. The drive is temporarily switched off. This protects the system from overheating.
The tailgate still does not work afterwards. Have the system scanned. The garage reads the stored fault codes from the control unit. This shows the possible problem areas: the sensor, switch, drive or power supply.
‘ Different faults produce almost the same behaviour. ’
When is a professional diagnosis needed?
Have the tailgate investigated if it stops regularly. Also have it investigated if it closes unexpectedly. Have the tailgate investigated if it only comes up with assistance. Also check specifically for cable problems. The wiring moves with every opening. The cables run along the hinge area.
A mechanic measures the connectors, wiring loom and sensor signals. The mechanic also readjusts the closing position. Replace parts only after a diagnosis. Different faults produce almost the same behaviour.
Do not continue using the electric operation if the tailgate moves skewed or makes strange noises. Each new attempt puts more strain on the drive. Support the tailgate if it will not stay open on its own. Make sure nobody stands under the tailgate.
Check the tailgate before buying
When buying a used Peugeot 5008, test the tailgate several times. Operate the tailgate using all available buttons. Pay attention to the speed and the sound. The tailgate should open and close without interruption.
After unlocking, check that the tailgate releases immediately from the lock. A brief hesitation suggests resistance or incorrect adjustment. If problems keep recurring, ask about previous checks of the battery, drive and wiring.
Problems with the Peugeot 5008’s automatic tailgate are often manageable. Check the voltage and any ice build-up systematically. Also inspect the seals, lock and sensors.

Frequently asked questions
The most common faults are that the automatic tailgate does not open, or only opens after several attempts, stops halfway, beeps twice or gets stuck. These are often caused by low battery voltage, activated obstacle detection or incorrect adjustment of the lock and rubber bump stops. Faulty sensors, connectors or wiring at the tailgate and hinges also occur. After intensive use, overheating of the electric motor can temporarily block operation.
Open and close the tailgate once fully by hand to allow the system to recalibrate. First check for dirt, ice or other blockages and make sure the battery has sufficient voltage; if it has overheated, wait about 10 minutes. Do not force the tailgate and, if problems persist, have the sensors, wiring, rubber bump stops and lock checked by a professional.
For the Peugeot 5008 from model year 2017 onwards, there is no specific, widely recognised factory fault known with the tailgate actuator. Problems do occur, but often turn out to be linked to low battery voltage, sensors or wiring, obstacle detection and incorrect adjustment of the lock or rubber bump stops. If complaints keep recurring, have the system scanned and also check for any recalls linked to the model and chassis number.
