When the engine is not needed, the Nissan Qashqai has a stop-start system that saves fuel. In case of prolonged stops, the system is activated after three seconds. There are times when the system ceases to function and you are forced to deal with a lot of trouble as a result. The car won’t start because of the system fault.
We have a comprehensive guide in this article to help you solve a system problem on any Nissan Qashqai, no matter if it is a 2015, 2016, 2017, 2018, or 2019.
It is possible for a Nissan Qashqai to develop a Stop-Start System Fault if there are several factors, such as battery terminal corrosion, excessive engine heat, loose battery terminals, faulty stop-start sensors, alternators that fail, software glitches, and faulty clutch paddle switches.
What Does Qashqai’s Stop Start System Fault Mean?
With the addition of a stop-start system to its lineup of cars, Nissan has expanded its product line. As a result, the engine cannot start until the accelerator pedal is released. The only exception is if your dashboard displays the “Stop/Start System Fault” message. There is a problem with the Stop/Start system detected by the Qashqai’s ECU. This mechanism turns off and restarts the engine instantly if the car is not moving. In order to reduce motor wear and tear, the stop-start system reduces idle time.
Nissan Qashqai Stop Start System Faults: Causes
This message may be displayed on your Nissan Qashqai for a variety of reasons. Here are some of the reasons:
Software Glitch
Just as with your computer or smartphone, your Nissan Qashqai requires software to function properly. There is no exception to this rule when it comes to the stop-start system. Problems can sometimes be caused by simple software bugs.
Clutch paddle switch malfunction
A malfunctioning clutch pedal switch could be causing your Nissan Qashqai’s stop-start system to malfunction. Signals sent by the clutch pedal switch activate or deactivate the start-stop system. Faulty switches may not deliver accurate signals to the stop-start function, causing the function to malfunction.
Overheating of the engine
When the engine overheats, the Nissan Qashqai’s stop-start mechanism can fail. Long acceleration, heavy transportation, and adverse weather are some of the reasons why engines overheat. The error appears as a result of the car’s inability to function properly.
Corrosion of battery terminals
There could be a number of reasons for your problem. Corrosion may prevent the terminal and battery from connecting properly, resulting in the stop-start system not working as it should because there isn’t enough power in the battery.

Unstable battery terminals
If the battery terminals on a stop-start system are loose, it won’t be able to charge enough to function properly and won’t be able to provide enough power to the system.
Failure of the stop-start sensor
Sensors play an important role in the stop-start mechanism. Unless this sensor works properly, the entire system could fail.
Faulty alternator
Occasionally, the alternator on the Nissan Qashqai can fail, causing the vehicle to have difficulty charging its batteries. This causes the start-stop system of your car to take longer to operate, so you notice that starting your car is more difficult.
Fixing Nissan Qashqai Stop Start System Faults
Nissan Qashqai stop-start system can be made to work properly with a few solutions:
Check and replace the main battery
Battery power provides the electrical energy required for a stop-start system to work, since it allows the engine to be restarted swiftly when necessary. An insufficient or weak battery can cause problems when it fails to supply the required current. Consequently, routine battery checks are essential, especially when the car has been idle for a long time.
Scan the vehicle
After checking the battery terminals and making sure they are clean and tight, if the problem persists, you should have your car examined. Your car should be scanned for error codes at a Nissan dealer to figure out what the problem is.
Check the battery terminals
In the event that you have just replaced your battery and it is still in good condition, you should check the battery terminals for corrosion or loose connections. After cleaning the areas with a wire brush and applying anti corrosion spray, tighten the terminals to prevent corrosion and loose connections.
Use injector cleaner
There is a possibility that buildup in the fuel injectors may affect engine performance and might cause problems with the stopping and starting system. The use of an injector cleaning device can increase fuel combustion efficiency by removing these deposits.
Can You Drive with a “Start Stop System Fault” on a Qashqai?
Qashqais can be driven with start-stop faults provided no other faults are present, which is the short answer.
Your car won’t be damaged by the system since it doesn’t directly affect the engine’s operation.
It’s still best to have the problem resolved as soon as possible because you won’t be able to save gas when you’re idling.
Self-checks and maintenance
You can maintain your vehicle’s software by updating your battery, cleaning sensors, and cleaning connectors on a regular basis. The Stop Start System’s overall health can be significantly improved by these practices.
Getting professional help when needed
Some issues may require professional expertise, even if DIY checks are valuable. It is advisable to consult a qualified technician if warning lights persist or if the system behaves oddly. It is possible to have more severe problems if you ignore persistent faults.
