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 it's possible to provide reliability information on new models quickly.

This forum has been very helpful with the G35, enabling TrueDelta to provide results for all model years (next set in February). Hopefully we can do the same with the EX35.

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.

That result has been posted. So far, the EX35 appears to have a repair rate worse than the average, but not far worse. If it's like the 2007 G35, the repair rate will improve after some initial bugs are out of the way. We'll see in future results, with the next update in November.

TrueDelta Vehicle Reliability Survey results

 

We've updated the results for the EX35 to include owner experiences through the end of March. A big thank you to everyone who helped make this result possible.

With a repair frequency of 96 repairs per 100 cars per year, the EX35 remains worse than average, largely because of common problems with the noisy fuel pump and the power tilt-and-telescope steering wheel.

With prompt quarterly updates, we'll continue to track them closely. The more participants we have, the better the information we can provide.

We've updated the results for the EX35 to include owner experiences through the end of June. A big thank you to everyone who helped make this result possible.

With a repair frequency of 99 repairs per 100 cars per year, the EX35 remains worse than average, largely because of common problems with the noisy fuel pump and the power tilt-and-telescope steering wheel.

With prompt quarterly updates, we'll continue to track them closely. The more participants we have, the better the information we can provide.

We've updated the results for the EX35 to include owner experiences through September 30, 2009. A big thank you to everyone who helped make this result possible.

With a repair frequency of 79 repairs per 100 cars per year, the EX35 has improved to average as previous common problems with the noisy fuel pump and the power tilt-and-telescope steering wheel fall out of the one-year window.

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 2008 EX, the percentage with no repairs is about 42, and the percentage of lemons is 4.

With prompt quarterly updates, we'll continue to track them closely. The more participants we have, the better the information we can provide.

We've updated the results for the EX35 to include owner experiences through December 31, 2009. A big thank you, once again, to everyone who helped make this result possible.

With a repair frequency of 58 repairs per 100 cars per year, the 2008 EX35 is about average. Earlier common problems with the noisy fuel pump and the power tilt-and-telescope steering wheel have largely fallen out of the one-year window.

We have two additional 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 2008 EX, the percentage with no repairs is about 66, and the percentage of lemons is 3.

With prompt quarterly updates, we'll continue to track them closely. With more participants, we could provide more precise information and cover all model years.

We've updated the results for the EX35 to include owner experiences through March 31, 2010. A big thank you, once again, to everyone who helped make this result possible.

With a repair frequency of 56 repairs per 100 cars per year, the 2008 EX35 is about average. Earlier common problems with the noisy fuel pump and the power tilt-and-telescope steering wheel have largely fallen out of the one-year window.

We have two additional 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 2008 EX, the percentage with no repairs is about 62, and the percentage of lemons is less than one.

With prompt quarterly updates, we'll continue to track them closely. With more participants, we could provide more precise information and cover all model years.
