Tilster Posted April 1, 2022 Share Posted April 1, 2022 So I picked up my 68 plate focus yesterday, on test drive the stop start didn't work due to low battery because of being sat on forecourt, understandable, I have now driven it 80 or so miles, and it's still not working, I've also noticed the wireless phone charger isn't working, is this connected to a low battery also? And if both of these things are connected to a low battery, how long do I need to drive it to charge the battery so everything works as it should? Or do I just ring the dealership about it?

unofix Posted April 2, 2022 Share Posted April 2, 2022 Just read the hundreds of threads on why Stop/Start doesn't work. Then read the almost 100 threads on State Of Charge (SOC). 4 Quote Link to comment Share on other sites More sharing options...
DaveT70 Posted April 2, 2022 Share Posted April 2, 2022 Yep, charge the battery Quote Link to comment Share on other sites More sharing options...
ianincheshire Posted April 2, 2022 Share Posted April 2, 2022 Quote I have now driven it 80 or so miles, and it's still not working you might find that it works the following day. In my experience, it needs to stand overnight to correctly re-assess the SOC level. In the years I had my Focus it (stop/start) only ever worked for a couple of days after a long journey.

isetta Posted April 2, 2022 Share Posted April 2, 2022 The start stop on my fiesta can go weeks without working even when I’ve been going 150-200 miles per week . It’s very inconsistent. I’d rather it was disabled permanently. Quote Link to comment Share on other sites More sharing options...

All down to "Key cycles" 👍 Quote Link to comment Share on other sites More sharing options...
Zemanel Posted April 3, 2022 Share Posted April 3, 2022 Bare in mind that it also won't work in cold enviroments . In the winter , it strugles to work but in summer it kicks in quite often Quote Link to comment Share on other sites More sharing options...

Eric Bloodaxe Posted April 3, 2022 Share Posted April 3, 2022 Lots of conditions need to be satisfied for stop/start to work correctly, a few here: https://batteryworld.varta-automotive.com/en-be/start-stop-does-not-work There seem to be two types of driver on here: those who are concerned if their stop/start doesn't work, and those who don't give a monkey's and wish they could turn it off permanently!😀 2 Quote Link to comment Share on other sites More sharing options...
pcaouolte Posted April 3, 2022 Share Posted April 3, 2022 My stop start hasn't worked for the last 4500 miles despite the car being used daily, commuting 15 miles each way on week days. As far as I'm concerned it's operating perfectly as it saves me having to switch it off. 1 Quote Link to comment Share on other sites More sharing options...

Wino Posted April 4, 2022 Share Posted April 4, 2022 It will soon be "May Day" (2nd May) and the day of the year to charge all our Focus's and do a little dance around our cars whilst the Maypole does its job 🤔 1 Quote Link to comment Share on other sites More sharing options...
kmoore04uk Posted April 7, 2022 Share Posted April 7, 2022 You need look at how old the battery is. I replaced mine about 3 years ago and it worked very well (in the summer months) for about 2 years. After that not at all unless the battery is fully charged with a charger. Quote Link to comment Share on other sites More sharing options...
