I have just bought my first Fiat. I love it. 500C 1.2 69hp Pop Cabrio. Manual gearbox.
BUT when moving off in 1st from a standstill it often creeps forward with very little power. On steep upward inclines, in 1st gear, it slows to a stop. I have to restart the engine and do a hill start And only then do I have enough power.

I have read these are known faults due to a software problem. Any ideas, advice, or information?

Hi what year of manufacturer is yours?

Sounds like the infamous one that was on Watchdog, probably needs a software update.

It's brand new

Is it the latest facelift model?

I'm not sure if the cabriolet version had a facelift. If it helps the model/version/series = 150-573-4-000. Left-hand drive as I am in Greece.

Yes it did though I'm not sure of model numbers above, the reason I ask is maybe although 'brand new' your car is actually an older model as the issues you're having are similar to what early euro 6 cars had, best bring it back to where you bought it and have it investigated and also find out actual build date.

As above and ask if there is any outstanding updates though it may be new so no one checked?

Thanks guys. I went back to the Fiat dealer and they are installing an update next week.
