Default Lexus IS reliability

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.

With the IS, the 2006 model year is included in the survey. The other years don't yet have enough owners signed up to participate, but a few are almost there.

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.

For the details, and to sign up to help out:

Hmm, it would be providing lots of information. Feel free to post more information about this project.

The survey is already providing a lot of information on other models.

For the IS, more participants are very much needed.

The 2006 is now in the survey, with a result possible for August. Other years are also getting close to the minimum.

To help get your year included:

You're welcome.

I'd like to be much more informative, but need more owners to participate before I can provide results for the IS.

I have much larger sample sizes for all competitors.

Those years are closer to the minimum, and we'll have an initial result for the 2006 this month.

That result: the 2006 actually appears to have a moderately high repair rate. But the sample size is small, so this result is asterisked.

With more participants would could provide precise results for all model years.

Results updated again, and the repair rate remains moderately high.

Additional participants very much needed, for all model years. Help get yours fully included in the survey.
