Because existing sources of vehicle reliability information left much to be desired, in late 2005 I started conducting my own reliability research at TrueDelta.com. TrueDelta reports absolute stats like "trips to the shop" that make the differences between cars much clearer. Results are updated four times a year, so it's possible to provide reliability information on new models quickly. Also, any significant changes in a model's reliability become apparent quickly.

Thanks to the help of a number of Dodge and Chrysler forums, we've had excellent samples of the 2005 and 2006 for some time (though larger would be better still). For more recent years, we could especially use more participants.

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, panel members will receive full access to the results for free.

Those results have been posted.

The 2005 continues to have a worse than average repair rate, while the 2006 is average and the 2007 might be a bit better than average. The sample size is marginal in the last case, so that result is less precise and asterisked on the site.

With more participants would could have a more precise result and include more model years.

We have updated results for the Chrysler 300, Dodge Charger, and Dodge Magnum. In terms of successful repair trips per 100 cars per year:

2005: 100, about average

2006: 62, about average

2007: 82, about average, smaller sample size than the other two years

2008 and 2009: not yet included in the survey

A big thanks to everyone who has been helping. We'll have further updates in May, August, and November. With more participants, we could provide more precise information and cover all model years.

We now have a separate results page for each model that includes the results for competitors. The page for the Chrysler 300, which includes results for all LXs:

We've updated the results for the LXs to include owner experiences through March 2009. In terms of successful repair trips per 100 cars per year:

2007: 80

2006: 57

2005: 85

All are about average. Sample size is smaller for the 2007 than the others--just above the minimum for a full result--so that result is probably not as accurate.

A big thank you to everyone who has been helping. We'll have further updates in August and November. With more participants, we could provide more precise information and cover all model years.

We've updated the results for the LXs to include owner experiences through June 2009. In terms of successful repair trips per 100 cars per year:

2008: 59, small sample size

2007: 72

2006: 64

2005: 57

All are about average.

A big thank you, once again, to this forum and everyone who has been helping. We'll have further updates in November and February. With more participants, we could provide more precise information and cover all model years.

We've updated the results for the LXs to include owner experiences through September 30, 2009. In terms of successful repair trips per 100 cars per year:

2008: 64, small sample size

2007: 66

2006: 72

2005: 57

All are about average except for the 2005, which is now better than average.

We've also introduced two new 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.

In the case of the 2005 and 2006 LXs, the percentage with no repairs is about 50, and the percentage of lemons is less than one. Not enough data yet to provide these stats for other years.
