Indeed, fiat take alternator charging and glow plugs very seriously so a official mass product recall seems to the the appropriate way to deal with such a minor issue.
The same company that didn't recall the mk2 punto with a well known airbag fault or the Euro 6 - 500 problem which they flatly denied was a problem. Oh and all the power steering issues on the grande punto which caused accidents and made national news and got Tv coverage.....
All those things are not as important as battery charging and your glow plugs working.
