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.

Hi Katarzyna,

You can, but there are two things standing in your way — first you will have to tax the van as a private vehicle, and that means you may end up paying more every year than the flat-rate €333 commercial vehicle road tax rate. Secondly, you will need to make sure you tell your insurer that the van is being used for private, social, domestic and pleasure use, as that may have an impact on your quote and coverage.

Hi John,

Lots of people find that their car's stop-start system stops working for no obvious reason, though it's disappointing that the garage fobbed you off rather than come up with a fix. 

We've had so many queries that we've put together a guide called Why won't my car's stop-start system work?

Have a read through that and see if it helps shine a light on the situation. Faulty temperature sensors and batteries in poor condition are very common causes.

Hi Roy, 

That's not something we've come across, I'm afraid. There can be many simple reasons for a stop-start system to not work (see our popular feature on that subject here), but usually they are temporary. I guess if your battery was replaced, there may be some additional reprogramming required, but that wouldn't be standard on all cars.

If someone has told you that this is necessary, make sure you get a second opinion from another garage, preferably an official Suzuki service outlet. And if Suzuki told you that, then ask for a little explanation.

We'd be interested in the answer if you want to pop a comment in below this at a later stage.

Hi Anne,

There are loads of different reasons why a stop-start system won't work as you might expect it to. Most of the time it's down to the condition of the battery or the drain on it, though it could be due to the ambient temperature, too. Here are a couple of items on the site to read through before you consider having the car looked at:

Hi Juliana,

We don't know of any common issue with the Insight, so it's probably a protection mechanism for the battery. We get a lot of similar queries, which prompted us to write the Why won't my car's stop-start system work? feature - well worth a read.

Hi Silvester,

We have got so many questions from readers about non-functioning stop-start systems (from all makes and models) that we put together this guide to help you get to the bottom of it:

Hi Natalia,

It’s actually Vodafone that supplies the data link through the OnStar built-in SIM card in the car, and it costs €125 per year, which gets you 100GB of data over WiFi. There is the option of 5GB per month for €15, or 10GB for €19.99, but obviously these will work out more expensive over a year than the 100GB plan.

Hi Declan,

Don’t get an X3 then — it has great seats, and is higher up, but has a ride every bit as hard as that of the 4 Series. Would you consider a Lexus? The NX SUV is really very comfy, and softer riding than most competitors, as is the Volvo XC60 (either the new model or the old one) as long as you avoid larger optional alloys and the R-Design pack.

Hi Robert,

Great choice. We published our Irish road test of that very car only last week and it's a good option for those that don't need diesel. The 1.4-litre TSI petrol engine features something called Active Cylinder Technology (ACT), which automatically shuts down two of the engine's four cylinders when the car is cruising or the engine is on light load. This saves fuel and is nothing to worry about in the least. By displaying when the engine switches into that mode it educates the driver as to when the car is being driven in its most efficient mode.

Anything else specific you need to know, just shout.
