I was recently on auto express magazine for those who saw my article. Fiat is well aware that these small little engines are just an experimental unit being thrown at the general public. First , they are not economical, I have found its really hard to keep past 40 mpg. I don't find it a problem because it can be really entertaining. However, the flywheel clutch design is poor as it will start vibrating sooner or later , being very unpleasant for city driving. Tell tale signs is when you hear humming noise when reversing! Simply don't accept excuse from your local dealer that its normal, absolutely not. The timing chain rattles pass 2000 rpm, again poor design. Most of us will be left with hefty repair bills once the warranty is over, hence I'm suggesting we all have a petition for an extended warranty on twin air models. We all need to act quickly before its too late and before we're left with huge repair bills. How to organise the petition is simply left in the hands of mighty guru's already predominating this platform. Info please, thanks.
