We've updated our reliability stats for the Grand Cherokee to include owner experiences through September 30, 2013.
Repair frequencies, in terms of repair trips per 100 cars per year:
2008 Grand Cherokee: 51, moderate, small sample size
2007 Grand Cherokee: 45, low
2006 Grand Cherokee: 44, low, very small sample size
2005 Grand Cherokee: 63, low, small sample size
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:
2007 Grand Cherokee: 57, < 1
We'll have further updates in February and in May. The more owners participate, the more comprehensive and precise these will be.
