The Nissan Qashqai regularly suffers from electrical faults, especially in models up to 2016. Problems with windows, central locking, infotainment and parking sensors are not uncommon. The cause is often blown fuses or faulty relays. Do you recognise these symptoms in your Qashqai?
Electric windows no longer work
You press the button, but nothing happens. Electric windows that no longer respond are a common issue in the Nissan Qashqai. This problem often occurs in older models and can have several causes.
The most common culprit is a blown fuse. First check the fuse box in your car. You will usually find it under the dashboard on the driver’s side. Replace a faulty fuse immediately with one of the same amperage. Be careful not to simply use a higher-rated fuse, as this can lead to dangerous situations.
Sometimes the problem lies with the switch itself. Especially on the driver’s side, where the button is used most often, the switch can fail due to wear. You can recognise this because the other windows still work. A garage can test and replace the switch.
For some Qashqai owners, the window mechanism turns out to be jammed. This happens mainly in winter, when moisture in the door freezes. Let the car warm up properly before trying to open the windows. In stubborn cases you will need to remove the door panel to lubricate or replace the mechanism.
‘ Parking sensor problems in the Nissan Qashqai are annoying and can lead to unsafe situations. ’
Parking sensors give error messages
Beeping even though there is nothing behind you, or no signal at all when you are about to hit a post. Parking sensor problems in the Nissan Qashqai are annoying and can lead to unsafe situations.
Dirty sensors are often the main cause. The small round sensors in your bumper are easily covered in mud, salt or snow. Clean them with lukewarm water and a soft cloth. Avoid aggressive cleaning agents that can damage the coating.
Is cleaning not enough? Then a sensor may have failed due to, for example, a knock against the kerb or ice build-up. A faulty sensor must be replaced. Garages can use diagnostic equipment to pinpoint exactly which sensor is causing the problem.
Sometimes the cause lies in the wiring or a relay. This occurs mainly after carwashes with pressure washers, where water can enter the bumper. Have a specialist check the wiring and, if necessary, re-insulate the connections.
Steps to fix parking sensors
- Clean all sensors thoroughly with lukewarm water
- Check for any visible damage to the bumper
- Test the sensors by reversing slowly
- If problems persist, have a garage read out the fault codes
Cooling fan keeps running
You switch off the engine, but the fan just keeps roaring. This problem is common in the Nissan Qashqai and usually points to a faulty relay. The fan then receives constant power, even when the engine has long since cooled down.
The cooling fan relay is located under the bonnet, usually in the fuse box. This small box contains several relays and fuses for different functions. The fan relay is often larger than the other relays. Check your manual for the exact location.
A faulty relay is often recognisable by a burning smell or a charred appearance. Replace the relay with a genuine Nissan part, as cheap alternatives sometimes fail quickly. The job takes about ten minutes and does not cost much.
Does the fan still keep running afterwards? Then the temperature sensor may be sending an incorrect signal. This sensor measures the coolant temperature and controls the relay. Have a garage test the sensor and replace it if necessary.
Do not ignore this problem. A fan that runs constantly will drain your battery. Especially if your car is parked overnight, this can mean you will not be able to start it the next morning.
Central locking does not respond
You press your key, but the doors stay locked. Or the other way round: you cannot lock your car. Central locking problems are common, especially in Qashqai models older than five years.
Start by replacing the battery in your key. A weak battery often does not send a clear signal. You can test this by standing right next to the door. Does the key work then? If so, the battery is nearly empty.
Does one door not respond while the others do? Then the problem lies with the actuator in that particular door. This actuator is a small motor that moves the lock. Due to wear this part can fail. Replacement costs several tens of euros, but you will need to remove the door panel.
In case of complete failure of the central locking, first check the fuses. There is usually a separate fuse for the locking system. Is that in order? Then the problem may lie in the control module. This requires specialist diagnostics at a garage.
‘ Faults in the infotainment system are frustrating, but are often solvable without expensive repairs. ’
Infotainment system will not start
A black screen where your navigation and radio would normally appear. Faults in the infotainment system are frustrating, but are often solved without costly repairs.
First try resetting the system. Hold down the on/off button for about ten seconds. In many Qashqai models the system will then restart. This often fixes software glitches.
If a reset does not help, disconnect the battery for five minutes. This forces a complete restart of all the electronics in your car. First disconnect the negative terminal, then the positive terminal. When reconnecting, do this in the reverse order. Note: after disconnecting you may need to re-enter your radio code.
Does the screen stay black? Then the fuse for the infotainment system may have blown. You will find it in the fuse box. Only replace it with a fuse of the same rating.
Some Qashqai owners report that the system does not start up at extremely low temperatures. This often resolves itself once the car has warmed up a bit. Does it keep happening? Have the dealer check whether a software update is available.
Battery problems and rapid discharge
Your car struggles to start or the battery is regularly flat. This is one of the most reported electrical issues in the Nissan Qashqai, especially in models built before 2016.
Early Qashqai models were often fitted with FIAMM batteries. These wear out faster than the later VARTA batteries. Test your battery with a multimeter. A healthy battery measures at least 12.6 volts with the engine off and between 13.7 and 14.7 volts with the engine running.
Is it reading lower? Then your battery is aged or discharging too quickly. Electrical consumers can continue to draw power while the car is switched off. This is called a parasitic drain. Examples include a faulty door sensor or a charging cable left plugged in.
If in doubt, have a garage carry out a starter current test. This test shows whether your battery still provides enough power to start the engine. It is best to replace a weak battery before winter, as cold temperatures speed up its deterioration.
Preventive maintenance for your battery
- Clean the battery terminals regularly with a dry cloth
- Check that the clamps are firmly attached
- Avoid lots of short journeys, as the battery will not fully charge
- Have the battery tested annually during your service
Warning lights flashing
Warning lights on your dashboard that illuminate or flash for no obvious reason. This may indicate a temporary fault, but also a serious problem in your electrical system.
Some lights come on due to loose connections or a weak battery. If the voltage in your electrical system drops too low, various modules can generate error messages. First check whether your battery is supplying sufficient voltage.
Some Qashqai owners see messages about open doors. This happens while all the doors are actually closed. It is often caused by a faulty door sensor or seatbelt buckle switch. Replacing these parts usually fixes the problem.
Do the lights keep flashing or do you see several messages at the same time? Then have an OBD scan carried out. This scan reads the fault codes stored in your car’s memory. Garages and some car dealers offer this service. That way you know exactly where the problem lies.
‘ When the alternator fails, replacement is usually the best solution. ’
Alternator and charging system
The alternator ensures that your battery is charged while driving. Problems with the alternator lead to a flat battery and electrical failures. In the Nissan Qashqai these faults are sometimes caused by frayed wires at the voltage regulator.
You will recognise this problem from a battery that quickly goes flat, even after replacement. The warning lights may flicker and electrical functions will not work properly. Test whether the alternator is working correctly by measuring the voltage with the engine running.
Are you measuring less than 13.7 volts? Then the alternator is not charging sufficiently. Check the V-belt that drives the alternator. Is it loose or worn? Then it needs to be replaced. If the belt is fine, the problem is probably in the alternator itself.
After long drives, let your engine idle for a moment before switching it off. This helps the alternator cool down and extends its lifespan. When the alternator fails, replacement is usually the best solution.

Frequently asked questions
The most common electrical faults in a Nissan Qashqai are rapid battery discharge, alternator problems, sensor and door faults, and failures in modern systems such as e-POWER or hybrid electronics. You can recognise battery issues from starting problems and illuminated warning lights on the dashboard, and alternator issues from a battery that runs down while driving and failing electrical functions. Door sensor and seatbelt problems show up as the car constantly reporting an open door, the interior light staying on or the battery discharging while parked. e-POWER or hybrid faults can be recognised by specific messages such as “e-POWER system fault” or error codes relating to overvoltage and weak batteries.
Common causes include an old or weak battery (especially pre-2016 FIAMM batteries), alternator problems (fraying wiring) and faulty sensors or switches in doors and seatbelts. Frequent short trips and many electrical consumers also speed up battery issues. You can measure battery and charging voltage yourself, check fuses, inspect plugs and earth connections, and clean door or seatbelt switches. If fault messages or starting problems persist, professional diagnostics are required.
You can reduce electrical faults by having the battery tested regularly and, in older (pre-2016) Qashqai models, replacing it preventively with a higher-quality battery (such as VARTA). During servicing, have the alternator and wiring checked for frayed cables and make sure fuses and sensors are clean and intact. Avoid lots of short trips, as these put extra strain on the battery, and have software updates carried out at the dealer. If you get unexplained fault messages, have the fault memory read out straight away so that small sensor or battery problems do not grow into major faults.
Average costs for fixing common electrical faults in a Qashqai (such as battery or sensor problems) are roughly between €150 and €400, depending on parts (e.g. new battery, sensors) and the garage’s labour rates. More complex issues such as alternator faults, hybrid/e-POWER or overvoltage errors can range from about €400 to €900, especially when genuine Nissan parts are used. Minor issues such as fuses, simple sensors or checking connectors are often relatively cheap (sometimes < €150) and partly DIY. Always call in a professional or Nissan dealer in case of recurring faults, warnings in hybrid/e-POWER systems, unexplained battery drain, or when several electronic systems fail at the same time.
Ignoring electrical faults can lead to systems such as power steering, lighting or the engine suddenly cutting out, which can create dangerous situations in traffic. A battery or alternator that continues to deteriorate can cause the car not to start or to stall while driving. Ongoing faults can also cause additional damage to electronic components and wiring. All of this reduces the reliability of the car and increases the risk of breakdowns at the roadside.
