Toyota Sienna Lemon Odds and Nada Odds

Toyota Sienna Lemon Odds and Nada Odds:

Other sources of Toyota Sienna reliability information provide only averages, which can conceal as much as they reveal. So we also report the percentage of Toyota Siennas with no repairs at all in the past year and the percentage of Toyota Siennas that are lemons (required three or more repair trips in the past year). These figures might surprise you.

These stats are promptly updated four times a year, to closely track Toyota Sienna lemon odds as the cars age. Others can be over a year behind. Only TrueDelta tells you how reliable the Toyota Sienna has been recently.

Toyota Sienna Lemon Odds and Nada Odds through December 31, 2012

General NotesNote the sample sizes in the right column. For a precise Nada Odds, it'd be best to have 50+ cars. For Lemon Odds, 100+. In most cases the sample sizes are between 25 and 35, and differences of less than six points are probably not meaningful. This is especially a factor with the "Lemon Odds," where nearly all scores are low.

That said, the Lemon Odds figures are probably much lower than many people suspected, so we've posted them. Similarly, the Nada Odds are probably higher than many people suspected. Even with the least reliable cars in this results set your odds of no repairs would be better than one in three. Surprised? MethodologyThe samples include cars for which we have at least nine months of data in the past year. The "Nada-odds" are adjusted based on the average number of months of data per car. These stats are very close to what they'd be if we included only cars with a full year of data.

Only successfully completed repairs are currently included in the analysis. Recalls and problems fixed with just a reflash or warning light reset are not included.

5-speed automatic FWD		 I have heard (and read) good things about the Toyota. I went to the dealer expecting the van to feel cramped, overpriced and dealer unwilling to negotiate. The last time I looked at Toyota (20 years ago) a dealer asked how much over retail I would pay.
