Interesting post....my wife picked up her S/S last Wednesday so when I got home, I thought I'd take it out. Only, this warning light was on the dash. I called Fiat customer services who put me through to the AA. They came out, but as I had backed the car off the drive onto the road, we couldn't replicate the issue.
A call to the Fiat dealer said it maybe that the onboard computer needed time to setlle in. I've never heard such a load of rubbish in my life. My brother in law laughed and said "they're not built to last forever you know

". More than a few hours would be nice though!
Anyway, I'll be speaking to the delaer this week about it, and one or two other niggles (frosted headlamp, lumpy ride?)
I'll give them a chance to resolve it, but if it isn't, I'll be rejecting it.
