We've updated our reliability stats for the Fiesta to include owner experiences through September 30, 2014.
Repair frequencies, in terms of repair trips per 100 cars per year:
2014 Fiesta: 44, moderate
2013 Fiesta: 29, low, small sample size
2012 Fiesta: 56, moderate, small sample size
2011 Fiesta: 44, moderate
We have two additional statistics, "Nada-odds" and "Lemon-odds", to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop:
2011 Fiesta: 65, 2
Additional participants always helpful (especially if you see "small sample size" next to the year, or no stat at all).
To view the repairs behind these numbers, check the stats for other cars, and sign up to help improve this information (next update in February):
