Technical Semi-Auto Gear change

[Dani500]

Hello there, wondering if someone could help me.
I bought a 2010, Fiat 500 dualogic less than a month back. I use it on the Auto, Economic setting with stop/start.
Last night I was approaching a red light so obviously broke and slowed down, almost to a complete stop and then the lights changed to green. The car has stop/start but as I didn't completely stop, it didn't activate it. I carried on and it started from gears 1 to 2 and 2 to 3, and the car was over revving. It did it from 3 to 4 also. Didn't pick up enough speed to get to 5th.
So as it would normally change at 2000rpm to 2nd, it got to the 2000, revved to about 3500-4000 quickly! and then changed to 2nd. Then same for 3rd and 4th.
I was wondering if the stop/start had anything to do with it... as it was almost activated? Or is the clutch slipping?
I pulled over. The stop/start engaged. I set back off and it was fine.
Can anybody help?
Thank you

It may have thought you needed to over rev to get to speed, like when heading up a hill etc.

Could have been just a glitch/blip (hopefully) or a sign of other problems. Clutch slipping isn't impossible, or unlikely depending upon mileage and the type of use it normally had.

It's just short of 30,000 miles. I don't drive erratically (honest lol)
I have 2 months warranty left so I guess I could monitor it for another month and see if it happens again.

Was only driving on a flat straight road, needed to go up gears normally. Definitely wasn't trying to go uphill and shift down gears. Was a totally different to what happens when going up hill. And if that was what is meant to happen, it would happen every time I drive on that road but it doesn't.

Seems to me from what you've posted that your car is faulty. If it came with any kind of warranty, I'd suggest taking it back to the place you bought it from.

Failing that, you'd likely be best finding an independent Fiat specialist that actually has real experience and understanding of the dualogic system. At the very least, they should be able to diagnose the fault for reasonable money & if it's anything really serious and you bought the car from the trade, you should be able to use that diagnosis as evidence to reject the car.
