Thanks to the help of this forum, TrueDelta received 24 responses covering 53 months of ownership for the 2008 Versa.
Though the result is asterisked owing to a marginal sample size, the result of 68 successful repair trips per 100 vehicles per year is nearly identical to that for the 2007 and about average. This suggests that reliability hasn't substantially improved for the car's second model year.
For the 2007 Nissan Versa, I have an average of 6.2 months of data on 131 cars. This is the largest sample size of any model--thanks, guys!
The stat of 65 successful repair trips per 100 vehicles per year (0.7 per vehicle) is about average for a 2007 model.

Others won't have reliability info on the 2008 Versa until June or even October. Everyone who has been participating -- thanks for helping TrueDelta provide this information first, by a wide margin.
We can always use more help. You can join by following a link on the results page. Nearly 200 owners of the 2007 have been signed up for some time. A few more owners would make the 2007 Versa the first model to 200!

Re: (frankohabs)
You're being misled by assuming that 68 trips refers to 68 different cars.
1. One car may have gone into the shop 68 times, meaning only one car was problematic.
2. It counts as a trip whether the trip is for something simple like a rattle or something serious like struts or a fuel pump.
You have to read the reason behind each trip and how many different owners reported trips to get a more accurate picture. I have a 2 warranty repair trips in there, one because a golf bag broke off the latch cover on the back of a seat, the other because I received the car with a defective battery cell. The latch was not a defect in the car and would not have broken if we hadn't broken it, but the dealer did fix both things under warranty so we reported them.
Related to the True Delta Reliblity site, take the MPG figures with a grain of salt. Since they don't calculate total miles driven into the average overall for a car, the numbers are off a little. Reporting a one gallon fillup at 50 MPG for 50 miles carries the same weight as reporting a 13 gallon fillup at 10 MPG over 130 miles. They take the 50 MPG, add the 10, divide by two and report the car at 30 MPG. It should be a total of 280 miles divided by 14 gallons and only 20 MPG.

It means that for every 100 Versas, there will be 68 repair trips that include a successful repair over the course of a year.
Batteries are excluded, so that trip wasn't included in the analysis. I know that sometimes the battery should count, but it would require overly detailed (and lengthy) instructions to deal with that sort of gray area.
The golf bag bit I wasn't aware of. That's a tough call, coming down to whether the broken part should have been able to stand up to the conditions it was subjected to. People regularly put heavy luggage in trucks, so the bits back there should be sturdy.
The program has an outlier control built in, such that the car with the most repair trips is adjusted to the next-highest number of trips, plus one. Which about 90 percent of the time means no adjustment at all.
The actual distribution for the 2007 Versa, with 131 cars reporting for about half a year each:
99 cars (76%) with no repairs23 cars with one repair trip6 cars with two repair trips3 cars with three repair trips0 cars with 4+ repair trips
This is a typical distribution for a car with an average repair rate.
The fuel economy example is an extreme, unrealistic case. Someone making the same argument performed the actual computations with their numbers, and the difference was a few tenths of a mile per gallon. And the more tanks / people you include, the smaller the difference between the two methods will be.
That said, I'll likely offer results using the more precise method in the future.

Re: (frankohabs)
All this math makes my head hurt. Makes me think of the movie "Clue". . . ."1 plus 2 plus 2 plus 1".

Re: (mkaresh)
Michael- thank you for clearing a lot of that up over the service calls.
And yes, I fabricated an extreme example to show a drastic difference in calculations just so it would be very easy to understand.
One thing we agree on. Over time the MPG figures do get closer to the actual number based on volume, even if they do remain off a little. I'm one of those whose actual mileage is now only 0.2 mpg lower than reported on your site when the discrepancy early in the life of the car was over 2.0 mpg.

Thanks for understanding.
I'm in the process of bringing additional people on. This will lead to more rapid improvements to the site--I've become increasingly overloaded.
