Mine cut out this morning. Did the normal stop thing then gave me the SS unavailable message followed by the need for a manual restart. Incidentaly, it was the first frosty morning since we had the car. A sign of things to come??

General Calling all start 'n' stop owners!
Mine has recently started to turn off when the car stops, and within 1 second starts again. If I turn off the heating/ventilation it can sometimes go a little longer (5 seconds) and then at other times behaves normally.
Probably battery voltage?

My TA (now done 6K) did this about 6 weeks ago, booked in to local dealers, told the battery was faulty, they replaced, few days later some problem, engine stops at lights etc, then fires back up within 10-30 seconds. Car is booked back in on 12th Nov, see what they say this time
Yes as I recall those symptoms were the subject of much debate earlier on in this thread, had the same problem on a TA I test drove a few months ago - very annoying. Would be interested to hear what the outcome is

Mine did this once this morning, as I was slowing right down to a stop at some lights. But then I kept rolling, and it was bloody cold (1 degree indicated at that point); I've had it start up straight away whilst rolling before (in the same place actually!), so I think I catch the car on the threshold at which the S&S starts it up again.
No biggie - system has behaved faultlessly otherwise, I'd rather it be cautious and ensure the engine runs than the opposite. It's always a lot happier to leave the engine stopped for ages when the weather is warmer - the internal resistance of the battery will be much greater when the temp is low, so it's cranking ability will be that much lower, the S&S ECM seems pretty adept at working this out.

Hi.
First at all, sorry for my english.
I am Spanish owner of Fiat 500 twinair S&S.
Yes..., I have the problem...
The issue can be hide several months, it can appear at any time, and it can disappear weeks after...
When the problem is active, I realize that the warnings appears when I brake or when I turn on the right indicator. I try to change the brakes and indicators bulbs, but it's not working...
Some news about that?
Regards.

Car went in on 12th, advised that no fault codes were being shown, a tech call was being raised with FIAT, as the car was seen late in the day, FIAT did not respond till today. FIAT have asked for the car to be in for two days while they carry out tests on the battery. Given that the battery was a replacement one anyway I would have to be very unlucky to have two from a faulty batch which is what FIAT seem to be saying as they don't know what else to investigate given the lack of fault codes. What is interesting is that the cars coils were changed under a recall yesterday, driving today the has not played up. Anyone know if there's a connection????My TA (now done 6K) did this about 6 weeks ago, booked in to local dealers, told the battery was faulty, they replaced, few days later some problem, engine stops at lights etc, then fires back up within 10-30 seconds.

Earlier this year my TA Lounge had an intermittent S/S problem. Initially displayed it was unavailable and car running a little 'lumpy' dealer took it in and said battery was below par and kept car overnight to recharge.
This was OK for a couple of weeks and the same thing happened again but car running very 'lumpy' and virtually no power. It was at this point garage diagnosed one of the coil packs had failed. After replacing the failed unit the problem disappeared. To recap: Faulty Coil Pack plus S/S problems appears there is a direct correlation.

Right - car stop start worked ok up to yesterday morning, then one instance of restarting all on it's own, and only one instance of it working on my 25 mile trip to work, the same on the return trip. All very strange I thought the coil replacement had it fixed, looks to me like the battery gets a charge up at the dealership, holds for about a week then the whole thing plays up. Alternator????? Any ideas from any other TA owners.

Been on exactly the same journey as you with the dealer, back and forward charged and failing a few days later, only got sorted when a Fiat Tech from Head Office was at the dealership and took it out connected to a laptop that showed the alternator had an intermittent fault causing the problem
Alternator replaced and 7 months and 17k miles later it still works like a dream every time every day.
Can't guarantee its the same problem but something to get them to look at.
Chrysler Ypsilon Limited TwinAir with DualFunction semi automatic gear box delivered begining of october. My car immediately developed a faulty brake pedal sensor that caused an intermittant fault with the hill holder and the car rolled back on banks. The stop start stopped working after about 24 hours after having the car, when conditions are right it stops the engine but after between 1 and 5 seconds it just restarts by itself. The car is now back with the dealers for a fourth time and i am waiting for someone to come out and look at it. The dealers dont know how to fix it they have charged the battery, put a new battery on and replaced voltage sensor on the battery. I am in a manual black and red courtsey car. Very disappointed with the car.

The car was with the dealer ten days the fourth time and it was still not fixed. The dealer have it again now for a fifth time and say it needs a new alternator but can't give me date for when one will be available. So i am now trying to reject the car under sale of goods. They have but me in an enterprise hire car a i10.
Wow that's a pain, surely an Alternator should be a stock part, I know with mine they replaced the Alternator the same day the Fiat Tech diagnosed it as faulty and its been fine since, Just a fob off till they get back and settled after Christmas / New Year no doubt
TBH would you not be better taking your 500 back and using it till the New Alternator comes in.?

Car in dealership for three days, battery sensor replaced, no fault codes found, alternator checked, no errors found, went for test drive with the tech, car seemed ok.
Two days later, car back to restarting after 2 - 10 seconds! The tech told me this was normal. Temps have been cold in Essex so decided this cold cold be factor. Have tested the car with NO air con or auto climate control on over the last week and the stop start has not kicked in once on my normal 25 mile trip to work, the first set of lights is 12miles from home.
Why would having the auto climate off stop the ss from working?
Any one has any ideas just what I do next ?????
Flahyphotos its a ypsilon twin air dualFunction ltd not a 500 though its built by fiat and shares the same underpinnings. Glad they have not given me the car back as its a nuisance spending time running backwards and forwards to the garage with it and it helps my attempt to reject it. Why should a new car need a replacement alternator?
With mine there was an intermittent fault on the alternator that only showed up when it was out on a road test with a laptop connected to the OBD Port the Fiat Tech was great, had it on the road and it recorded the alternator cutting in and out which it was not doing when the car was in the workshop. Based on this they replaced the alternator and its been rock solid since S&S is just perfect.
Not saying yours is the same but something worth investigating

Update on my TA stop start problem - car restarting after 5 second
Second new battery fitted, In depth testing showed battery was not holding charge, all other systems checked out ok.
Now testing car
Note
The software was upgraded, I can now fully turn off the stop start, I.e it stays off every time the car starts a new trip. I also was told that the ss will work with the climate control on and the heated rear screen on.
Looks like Fiat have made some important changes to the system.

Having looked on the FIAT tech info site, I can confirm there is a service action notice for stop start issues, and revised ECU calibrations have been issued. I can't see the date of this bulletin (it doesn't say so on it!), but it does say it replaces a previous one dated 31/10/12 - so it's obviously after this.
Bulletin ref is: 1056 2 311 RA
