Because existing sources of auto 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 any significant changes in a model's reliability become apparent quickly.

This month we'll have an initial result for the 2007. Not quite enough responses for the 2006, and the 2008 isn't yet included in the survey because too few owners have signed up.

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 receive full access to the results for free.

Vehicle reliability research

 

Updated result for the Azera this week. We're a couple responses short of the minimum for the 2007--so additional participants would be very helpful.

Car reliability research

 

You're certainly welcome.

We'll have new results in May, with a preview next month for participants.

Need more for the Azera, especially for the 2009 and up. Help us provide the best possible information on your year:

Car reliability research

 

We have updated results for the Azera. In terms of successful repair trips per 100 cars per year:

2007: 53, about average, close to "better than average"

2006: 93, about average, close to "worse than average"

Sample sizes are small in both cases.

A big thanks 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.

Updated results next month. Additional participants would be very helpful.

Car reliability research

 

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

2007: 67

2006: 67, small sample size

Yes, same result this time for both years, and both are about average.

We'll have further updates in November and February. With more participants, we could provide more precise information and cover all model years.

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

2007: 43

2006: 81, small sample size

We'll have further updates in February and May. With more participants, we could provide more precise information and cover all model years.

89 Azera owners now signed up. A good start, but more are needed to provide precise results for all model years.

For the details, and to sign up to participate--with any car, not necessarily a Hyundai:

Car reliability research

 

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

2007: 65

2006: 97, small sample size

Both are about average. We'll have further updates in May and August. With more participants, we could provide more precise information and cover all model years.

We have updated results for the Azera to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

2007: 55, about average

2006: 104, worse than average, small sample size

We'll have further updates in August and November. With more participants, we could provide more precise information and cover all model years.
