We've updated our reliability stats for the ATS to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):

2014 ATS: 45, high
2013 ATS: 86, high, small sample size

I'd love to get rid of those sample size notes and cover additional model years. With additional participants, this would happen.

For the repairs behind these stats, reliability information on other models, and to sign up to help improve this information:
