Lexus IS vs. Kia Optima Lemon Odds and Nada Odds
Other sources of Lexus IS and Kia Optima reliability data provide only averages, which can conceal as much as they reveal.

These figures might surprise you.

Lexus IS 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.

| Year | Body/Powertrain | Comment |
| 2010 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic AWD |
It is top notch, or at least historicaly. Lexus commands respect. |
| 2010 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
Good care of customers and stand behind product, good resale value and reliability |
| 2009 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
Strong resale value. Good brand image, I live/work in Beverly Hills and still holds it's own against European rivals for much less. However, some brand snobs will throw their nose. Eh, who cares. |
| 2008 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
Lexus cars in general are rock solid. There is definitely a return to investment quotient, in design, features, performance, and reliability, which translates into high resale value. |
| 2007 | 4dr Sedan 204-horsepower 2.5L V6 6-speed shiftable automatic RWD |
We owned an SC400 before and liked Lexus. |
| 2005 | 4dr Sedan 215-horsepower 3.0L I6 5-speed shiftable automatic RWD |
Lexus stands for quality and is classy wihtout being too snobby. |
