That must be a new thing. I've never seen a house with airbags 🤣

An empty crisp packet set off my collision warning system, wasn’t expecting that.

You might have more difficulty in future - as far as I can see the only current (2024 facelift) version with ACC as standard is the ST, though it still seems to be available as part of the driver assistance pack.

Btw not clear if the car Colin posted about is an actual 2024 model, or one of the last pre-facelifts registered in 2024.

What flavour?

Sea Salt.

It was a multipack, couldn’t see the flavour,

my son said they could have been ‘Walkers’

Pun intended lol

I have a 2024 automatic puma 3 weeks old 

hybrid works most of time but it stops working around 20% of the time ford have looked at car took it on 1 testdrive for 10 mins & say it’s fine 

I’m really annoyed with them I explained it’s only happening a few times so they need to do lots of trips over a hour & then they would believe me, 

they say battery full but when it’s not working you get no electric boost & no drag on deceleration also when hybrid isn’t working it also stops the stop start function.

car works perfect in every other way but MPG down we did a 150 mile trip other day & no hybrid & no stop start, they just don’t believe me.

i had a 2022 puma automatic & it never did this I am annoyed with ford for not taking me seriously

Is the 12V battery in good condition?

I've been lurking on Suzuki forums of late, thinking of a Swift as a possible eventual replacement for my wife's car.

I've noticed several threads describing similar issues with the mild hybrid system. There is the (rare) instance of an actual fault in the system, but in most cases the response from dealers/manufacturer is related to drop in ambient temperature as winter approaches, ie the system only operates when engine oil is fully up to temperature. 

Might not be relevant here of course, but it's a thought.

I'd check the Yaris out first

Yes, I keep mentioning that, a fair bit pricier, of course, but the main issue is in 40+ years driving she's never even driven a 2 pedal car and is rather wary of making the switch now. There's not much small manual stuff left now - Toyota Aygo, Hyundai i10/Kia Picanto is about it - and even the Swift is more supermini than city car.

As I've mentioned elsewhere, I have looked myself at the Corolla and rather liked it. If they could squeeze the Corolla powertrain into a Yaris (I believe they're largely based on the same platform) I might fancy that myself. 

(There's always the GR Yaris of course, which can be had with manual, but with around 280 hp and costing around £45k it's a bit much for popping to the shops !😀)

It's the same principle, just a 1.5 engine running it instead of a 1.8 or 2.0

Yes, and I understand the Yaris 1.5 is basically a 3 cylinder version of the 2.0. I keep idly wondering if the 4 pot would fit. Possibly not, given that in the Corolla they have to fit the 12v battery in the boot on the 2.0 version, and the Yaris boot is not that big to start with!😀

Booked car in at ford dealer for week later, next day all working fine and as worked ok since then, stopped disabling stop/start so generated/motor as to keep starting engine and using hybrid battery power, is that the answer? Cancelled booking at ford because as a mechanic I know they will say no fault found after road testing/thrashing my new car😏 by the way my puma is automatic which is great but stops you changing some settings, ie can’t shutdown hill start assist which is far to slow releasing brakes so you set off fighting the brakes which is no good for gearbox/brakes, so you have to use handbrake anyway! I love this car and with a few tweaks it would be 😌 great

Thank you very much for the hint that turning off start stop may cause the hybrid problems, it seems so far to work on my 2024 Puma.

Hi, did you manage to solve the problem? mine has the  issue...

Just an update, drove to Scotland on holiday, fault occurred 3 times over 10 days driving around NC 500, other wise car was great to drive. I’ve since used a diagnostic tool and fault on BECM - battery energy control module comes on when hybrid system stops working, so there’s a fault! When I start car either from cold in morning or when I’ve stopped and restarted while engine still quiet warm, if hybrid system works it keeps working or if it doesn’t work it doesn’t work until I’ve switched everything off for at least 10 minutes and then restarted 😏 not cleared fault codes( there’s a few others) and booked car in at dealers. They can’t get me in until mid December 😒 I’ll update when cars been in, as I’ve already mentioned I’m a mechanic just about to retire so they won’t be able to just fob me off👍

I drive my Puma in ECO mode continually and find on occasions that regen/reactive braking does not kick in when lifting foot off the accellerator. Took car into dealership who did not really understand my concern, did a diagnostic test and pronounced car OK. Spoke to a technician who suggested that when underseat battery is full this mode does not work. Not happy with explanation I contacted Ford customer services who not only did not respond to my email but when phoned, I was told that they could not help and referred me back to the dealership. All I want to know is if what the technician said is fact. Any helpful comments???

I would expect that to be fully true.

Regen brakeing has to be able to 'dump' the generated power somewhere and if the battery is full then it can't charge it anymore. So yes, I would expect regen braking to not work when the battery is fully charged.

I have solved mine, it is the 12v battery state of charge. This chart explains the problem, when stop/start is disabled so is the hybrid system. Keep the 12v charged hybrid works.

That is very strange.  The hybrid battery handles warm restarts, so the 12v battery shouldn't be under much strain just to keep the radio and heater fan going while stopped.

Only thing I can think of is that the 12v battery is prioritised by the generator so the engine is kept running while charging that one.  But it seems bizarre not to use the over-run and regen braking to be charging the MHEV battery for the short periods of time where there's a large amount of regen occuring.

Have you proven this theory by keeping the 12v battery charged by an external charger?

Regards car running away with you I have just posted mine is doing the same thing I am an advanced driver so you can put the jokes away as when it happens the first time it induces panic, mines an auto I had it in neutral feet of the pedals and it was still accelerating

Accelerating in Neutral?  Or just revving? 

As this is the second one, there's obviously a serious fault with them which will lead to a recall when Ford figure out which part is causing it.

Yes I have, hybrid works every time. If I do a lot of short trips to Tesco it stops, but works again after I have charged it with my CTEK charger. With longer trips it always works.

Thank you.  I had hoped the earlier 12v battery issues wouldn't be such an issue in the MHEVs with a totally different charging & stop/start system but it seems that's not the case after all.

He's an "Advanced Driver" Tom, he knows what he's talking about 🤣

I guess he gets good MPG driving around in neutral 😉
