Hi Debbie,

It doesn't sound to us as if this is anything to do with the stop-start system, but actually an issue with the engine itself that needs looking at by a good mechanic. You've not told us which generation of EcoSport you have, nor which engine it has, but the 1.5-litre TDCi diesel has a known issue with the turbocharger wastegate valve that could cause engine running issues. It might be worth mentioning to the mechanic when you bring it to be checked.

Best of luck

Hi Kieran,

We would expect most stop-start issues to be sorted by a new battery, but the installer is correct: auto stop won't always work. In fact, we get so many queries about the subject that we wrote this feature you may find of interest: Why won't my car's stop-start system work?

Expert answer

Hi Kate,

There are loads of reasons for an engine's stop-start system to stop working (see our Why won't my car's stop-start system work? feature), but it rarely is linked with a dangerous issue. 

Saying that, there's no harm at all in bringing your car to a good mechanic to have it diagnosed to confirm that nothing major is amiss.

Best of luck with it

Hi Mirza,

That's a really unusual one and you're best getting the car along to a good garage to have it inspected. There's a known issue with the original Peugeot 5008 1.6 diesel where the earth connection to the starter fails causing all kinds of random engine and starting issues, so this could be related, but either way you'll need a mechanic to fix it.

Best of luck

Hi Clare,

Stop-start systems are a source of annoyance for a lot of people. We get so many queries about them that we wrote this feature you may want to read: Why won't my car's stop-start system work?

Saying all that, the point of a stop-start system is to reduce fuel consumption and emissions, so it's seriously pointless to go on a drive specifically to charge up the battery to make it work. It could be that your battery needs to be replaced completely.

Hi Dave,

There is no recommended way to deactivate the stop-start system permanently. If you turn it off using the button in the car, it will always come back on next time you start the car. 

Have you read our Why won't my car's stop-start system work? feature to try to get to the bottom of the issue?

Expert answer

Hi Razanne,

If this is the diesel version, it's possible that the issue has nothing to do with the stop-start system at all, as its engine is known to develop problems with the fuel injectors that could lead to poor running and stalling.

Otherwise, all we can suggest is that you read our Why won't my car's stop-start system work? feature to see if anything helps - and persevere with your mechanic to get to the bottom of the issue. An auto-electrician might be worth visiting, too.

Hi Bepin,

There are many reasons why a car's stop-start system will not work. And we get so many queries about it that we've put together this Why won't my car's stop-start system work? feature.

Give it a read and if you're still not convinced, then bring your car along to a good mechanic to have it diagnosed.

Expert answer

Hi Gloria,

Stop-start systems generally don't have any settings as such. They are on by default and will automatically turn the engine off when appropriate. The driver can manually switch the system off when the car is running.

So basically it's on or off. Leave the system on for (slightly) better fuel economy in slow traffic situations where you might be stopped for prolonged periods of time.

Expert answer

Hi Beth,

Stop-start systems from all car makers do indeed have a long list of situations in which they won't work. We get so many queries about it that we wrote a guide called Why won't my car's stop-start system work?

It's certainly preferable to have the stop-start system not working rather than the car cutting out when you don't want it to.
