For the life of me I can’t work out why it wasn’t working I’m so pleased I see this thanks Chris

I wish I had this "problem" of start/stop not working. I hate it but it works too well on my Subaru. And I think that start/stop is more nocive for the environment because it deteriorates, the battery, the starter and even the engine prematurely. I always disable it.

To reactivate stop/start: ignition on; press right hand fog light five times; turn the hazard warning lights on and off three times. Worked for me, though you may have to repeat the process at times.

In my case my Ford Focus start-stop stopped working because of a faulty sensor, this also stopped the part assist from working. New sensor fitted, everything was back to normal.

*Ive since uploaded how to fix this on my channel.*


You can reset your stop/start in a mk8 fiesta (might work on other models) but turning on the ignition (but not the engine) activate the dipped headlights, flash the full beams 5 times and then press the brakes 3 times. The battery light on the dash will them flash. Turn off the ignition and it will reset. The battery being over 75% and the engine being up to temp still applies. Enjoy!

The problem is the smart alternator doesn’t seem to allow charge to go to the battery due to saving the planet, the bms (battery monitor system) says not today, even after hours of driving the battery never charges. Solution was to purchase a smart charger and keep topping up the battery, all we need is a software update to fix these issues and also to stop the vehicle going into deep sleep allowing the smart features to work

[daviddowding]

Does that mean this is a bigger problem in the summer than winter when the blower and lights are on much more.

Thanks for the Video. So what is 75% of charge in volts Ford Focus LZ 2016 1.5 ecoboost has this issue! Resting Batt Volts 12.3V engine running Batt Volts 14V.
Car has not been sitting, just did a 4 hour non stop trip(with lights on fog & Sydney Tunnels) still Stop/Start not working. 2 1/2 year old battery 400$ oz
Put the heater on really (Aircon in Australia ) or put the headlights on! Is not that going to use more fuel and create more emissions, is not that a bit like a dog chasing its tail.

My Kuga had new battery three months ago. I’ve just driven a round trip of 560 miles last weekend and yesterday the start stop stopped working again so it’s not the battery. I’ll need to book it in to Ford I guedd

[MrKhunJen]

I drove my car for about 4 hours the other day as I thought that the battery was low (as I've just bought the car 2nd But now the auto start/stop is still not working.... surely 4 hours motorway driving has fully charged the battery?

[balenbeta]

What is the average time for lowing the power of the auxiliary battery after witching off the vehicle?

[damme]

the sign comes up on mine, but it never stops not that i want to use stop start. I think in fact it uses more fuel if its stopping at every traffic light and the traffices moving steady

[kathymcmahon]

I have tried this but my Stop/Start still hasn't started to work again on my Fiesta Vignale 2021 model 🤷🏼‍♀️

[Neil-Aspinall]

OK that is making sense now. I haven't driven the work Transit Custom regularly for a while now and this explains why it's not working as the mo. Is there somewhere in the dash menu to check the battery power level?

[camilocheryl]

That stupid feature i hate on my 2018 escape, many times happened to me in a stop light, then when i step on the gas the car won’t auto start and I’m left with angry drivers at my back! Then the process of putting it to park/turn off key then On again just to start the engine again

[comesefosseantani]

Hi Chris ! I have this problemi on my Puma 1500 td. The start stop doesn't work, and the malfunctioning light appear for few seconds on the cockpit. The car isn't used every day...and this could be the reason. Have you other ideas about this fault? Tks so much.

[nataliemartin]

I've noticed the fan kicks in under the bonnet and it's quite loud? Also this started to haven after not using my car for 3-4 weeks straight

[garyhaywood]

I have a mk4 focus st brought it In September from main dealer. Its never worked u till today when I did a battery reset and it worked strange away . Five high been flashes followed by 3 pushups on the break? Wait for battery to flash then battery reset . I was supposed when it worked . My battery was tested and its health battery .

[Mia-cwlg]

I have a focus MK3.5 (2016), bought it last year and I noticed 4-6 months ago the start stop isn't working anymore. I drive my car every day for 5-6 hours and never had any issues with turning on the engine or any other electrical issue even in cold temperatures. There isn't any warning light or notification about start stop not working, it simply doesn't work. What could be the problem?

[colinpowell]

I have a Hyundai 2023 i30 48v mild hybrid 7dct.

Low mileage of just 6000 from new.

All was working fine.

Had hyundai do it's first yearly

They said all good batteries are near full etc

1 month since the service NOW the stop /start 'A' LIGHT is coming on when braking / slowing down BUT STILL MOVING at say 15 mph? It still works as normal in traffic, at lights as it should WHEN CAR IS AT A STANDSTILL but now the light is coming on at low speeds of 15 mph and the car has not stopped
