We've updated our reliability stats for the Grand Cherokee to include owner experiences through December 31, 2013.
Repair frequencies, in terms of repair trips per 100 cars per year:
2014 Grand Cherokee: 64, high
2013 Grand Cherokee: 44, moderate, very small sample size
2012 Grand Cherokee: 46, moderate
2011 Grand Cherokee: 43, 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:
2012 Grand Cherokee: 66, 4
2011 Grand Cherokee: 64, < 1
We'll have further updates in May and in August. The more owners participate, the more comprehensive and precise these will be.
