We have an updated reliability stat for the 2004 Quest--with about 129 repair trips per 100 cars per year, it's worse than average. This is based on a 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.

We have updated results for the Quest to include owner experiences through September 30, 2010. The updated stats of 159 repair trips per 100 cars per year is worse than average, but based on a small sample size.

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

Starting this month we have a new question to measure, as objectively as possible, the severity of a problem. Many people have been asking for reliability stats that weight problems by how severe they are, and once we have enough responses with the revised survey we'll start providing this.

In about a week we'll start previewing the next set of results to participants. The preview results will be updated as responses come in.

The 2004 remains the only year in the survey, and we'll again have only a partial result for it.

We have updated results for the Quest to include owner experiences through June 30, 2010. The updated stats of 105 repair trips per 100 cars per year is about average, but based on a very small sample size.

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

It took longer than I'd hoped, but we now have a reliability stat for the 2004 Quest--with about 133 repair trips per 100 cars per year, it's worse than average. This is based on the year ending March 31, 2010.

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

We're going to have a partial result for the 2004 next month. And about time--sorry it took so long.

I'd like to cover all model years--just a matter of getting more owners involved.

Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

We're currently a couple responses short of the minimum needed to provide a stat for the 2004. Other years getting closer.

Hello, I see some people have had experience dealing with Nissan about getting the black box read. We were stopped at a red light and the airbags deployed causing us to hit the vehicle in front of us. We have a 2009 Nissan Rogue. This happened 2 months after we bought it. Now we are fighting with insurance and Nissan to read what actually happened and caused the accident, but we are not getting anywhere. Is there anyone out there who reads the black boxes? We are expecting a baby and the vehicle is not trustworthy. How do we proceed?? Any help or advice is greatly appreciated.

The 2004 is now in the survey. We hope to have a result in February, but it's going to be tight. Additional participants would be very helpful.

Enough owners of the 2004 have now (finally) signed up to include it in the survey. Thanks, everyone. We'll include other model years as more people sign up.

90 Quest owners now signed up, and the 2004 is only four short of the minimum.

We're just a few participants short of the minimum now for the 2004.

Updated results for about 150 other models next month. Let's get the Quest included.

Latest results recently posted for many other minivans. Still hoping to include the Quest, but this depends on how many owners sign up to participate.

Next update in May. Unfortunately, still not enough Quest owners to include it.

...but not there yet. Updated results for 92 other model / model year combinations in a week or so. Would like to include the Quest, but not enough owners have signed up yet. The 2004 is about 2/3 of the way to the minimum.

I recently added a Common Auto Repairs Database (CARDb) to the site. People posting common repairs can include a link to a forum thread discussing the problem. I hope this will make it easier for people to find this information, while helping to grow the forums that have been lending a hand with the research.

Updated results for most other minivans next month. Still not collecting data on the Quest, but getting closer to starting with the 2004 and the 2006.

As the (very satisfied) owner of an '04 SE, I find Nissan's position regarding defects in the early '04's puzzling. They admitted the (extensive) problems exist. In fact, they took the unprecedented step of extending the warranty on all '04 Quests. So why give someone the run-around?

I have had my 04 quest at the dealer 6 times for the passenger sliding door not working. April 5th my airbag deployed for no reason and 15 min later my car alarm sounded for 20 min. Nissan corporate is not covering the airbag replacement. They claim I was in a moderate to severe collision which is totally not true. There is no damage to my car besides the airbag deploying and locking the seat belts. This car is not reliable! I have retained a lawyer to fight Nissan. If I was on the highway when the airbag deployed there is no doubt I would have had an accident. My kids are afraid to ride in the car. Nissan is trying to cover up this defect!!
