I wanted more up-to-date car reliability information that included actual repair rates. So in late 2005 I started getting people together to make this possible. TrueDelta now updates actual repair frequencies, not just dots, four times a year, to track cars closely as they age.

I'd like to cover all model years from 1995 on -- just a matter of getting enough owners involved. 405 signed up so far.

Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.

To encourage participation, participants receive full access to all results, not just those for Jeeps, for free. I'll share results in this thread after each update.

We have updated results to include owner experiences through December 31, 2009. Results for the Grand Cherokee, in terms of repair trips per 100 cars per year:

2007: 58, about average

2005: 26, better than average

Small sample sizes in both cases. With more participants, we could provide more precise information and cover all model years.

We have updated our reliability stats for the Grand Cherokee (on our redesigned site) to include owner experiences through September 30, 2011. Repair frequencies, in terms of repair trips per 100 cars per year:

2011: 100, worse than average

2008: 35, better than average, very small sample size

2007: 85, about average

2006: 39, better than average, very small sample size

2006 Commander: 62, better than average, very small sample size

2005: 123, worse than average, small sample size

2004: 72, better than average, small sample size

2002: 153, worse than average, very small sample size

2000: 100, about average, very small sample size

Much of the variation from year to year is likely due to the small sample sizes for every year except the 2007 and 2011.
