Toyota 4Runner reliability (please sign up)

mkaresh · 10-25-2007, 05:35 AM

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.

I've started collecting data on the 2007, but the sample size remains marginal. And for other model years the sample size isn't quite to the minimum needed to get started. So I'm grateful that the admin of this forum has offered to help get the word out about the research.

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.

Anyone, anywhere can participate.

These guys are trying to gather more relevant and accurate data on vehicle reliability. The results seem to be interesting, but will be better with more datapoints. Anyway discussed it with them, and thought it might be a good idea.

I have been recording the data form our 3 vehicles for some time.

Thanks, Bulldog.

Should have initial results for the 2007 in February. Still need more participants for this and other model years.

mkaresh · 01-02-2008, 09:00 AM

A number of model years are now very close to the minimum needed to be included in the main survey--for example, the 2005 is just two owners short.

Details here:

I put mine in a couple months ago and have already recived 2 serveys. I just cant figure out how to access the info on the site.

mkaresh · 01-28-2008, 09:02 AM

I apologize for not seeing and responding to your post sooner.

Have you been able to access the surveys? For those, just click a link in the emails.

To see the results, look in the "Reliability" box on the home page. You'll find three links there. The second goes to the results for the main survey, the third goes to a second survey that covers things the main survey does not.

I hope this helps. I know that the site can be confusing for many people, and am working to fix this.

AlexJet · 01-28-2008, 09:54 AM

I'm in for 2005

mkaresh · 03-03-2008, 09:31 AM

I expect to have at least a few model years in the next update, in May. The sample sizes are borderline, though, and a few additional participants could make all the difference.

For the details, and to help get your model year included:

About to start the last month of data collection before the May results. A few more participants could make the difference been having a result and not having one, it's going to be close.

mkaresh · 04-27-2008, 10:09 AM

Those results soon.

Additional participants always helpful.

mkaresh · 05-24-2008, 12:14 PM

Those results recently posted.

One year of the 4Runner fell a single response short of making it into these results. I'd like to include not only this year next time, but a few others as well.

A few additional participants could make all the difference.

The next update is only a few weeks away. Additional participants would certainly help.

282 4Runner owners now signed up. A good start, but more are needed.

mkaresh · 08-12-2008, 10:20 AM

The 2003, 2005, and 2007 will be in next week's results. All three results will be asterisked for marginal sample sizes, though. The 2006 didn't quite make it.

In other words, need more participants for all model years.

Michael, have you tried yotatech dot com? tons of 4runner members there you can get to sign up too.

mkaresh · 08-19-2008, 09:36 AM

I've thought about posting there, but have been concerned that the membership there is even more into heavy off-roading and modding than at other 4Runner forums.

mkaresh · 09-11-2008, 09:54 AM

Results posted for the 2003, 2005, and 2007. The sample sizes are small, so the results are asterisks and only visible to members on the site. But the repair rates appear to be better than average for all three years.
