Can’t decide which Toyota Sienna is right for you? The Toyota Sienna model years are outlined below so you can decide which model year is best for you.
A spacious interior and excellent safety ratings make the Toyota Sienna one of the most popular family vehicles.
Each model year has its own advantages and disadvantages, as the vehicle has a long history of production.
Sienna model years are detailed in the guide, from the best to the worst. The book also introduces a neutral ground that represents the middle ground between the best and worst options.
There have been four generations of the Toyota Sienna:
| Generation | Years |
| Toyota Sienna (4th generation, XL40) | 2021-Present |
| Toyota Sienna (3rd generation, XL30) | 2011-2020 |
| Toyota Sienna (2nd generation, XL20) | 2004-2010 |
| Toyota Sienna (1st generation, XL10) | 1998-2003 |
The key differences between each generation are essential to making an informed decision. Following a thorough review of data from several reliable sources, we’ve rated model years by generation as ‘Best,’ ‘Neutral,’ and ‘Worst.’
As the name implies, a neutral year is a model year with neither significant problems nor exceptional reliability or owner satisfaction. Based on all the factors we considered, they may be evenly balanced between advantages and disadvantages, or they may be average.
According to model year, we have the following categories:
| Generation | Best Years | Neutral Years | Worst Years |
| XL40 (2021-Present) | 20212023 | 2022 | N/A |
| XL30 (2011-2020) | 201120122015201620182020 | 2013 | 201420172019 |
| XL20 (2004-2010) | 20052006 | 20042009 | 200720082010 |
| XL10 (1998-2003) | 200020012002 | 19981999 | 2003 |
Rankings in the table above were determined by a variety of factors, including:
- Owner reliability surveys (reports)
- Costs associated with maintenance on an annual basis
- An evaluation of safety
- According to Consumer Reports, Consumer Reports is reliable
- Consumer Reports’ owner satisfaction score
- NHTSA investigations, recalls, and complaints
- Ratings on Edmunds by owners
- JD Power ratings for owners
- The Kelley Blue Book (KBB) provides owner ratings
- Ratings on VehicleHistory by owners
- Reviews on Cars.com by owners
Recalls issued by the NHTSA are one factor that negatively impacts safety. There is a correlation between a car’s reliability score and its reliability rating when the recall rate is high.

Motorbiscuit.com reports the following problems with the Toyota Sienna:
Electric sliding door troubles
Electric sliding doors on the Toyota Sienna are convenient, but they can develop issues if they were manufactured between the mid-2000s and early 2010.
It is most common for doors to malfunction by not opening or closing properly, getting stuck, or not functioning at all. Problems related to door motors, misaligned tracks, and worn-out hinges and cables can occur.
Dashboard cracks
Since the late 2000s, Siennas has suffered particularly from the problem. They can cause unsightly cracks and reflect deeper issues with the durability of the materials and the quality of the interior construction. By exposing yourself to intense sunlight and heat, you may aggravate this problem.
Failing oxygen sensor
Particularly in Siennas from the mid-2000s and early 2000s, an oxygen sensor failure is possible.
Fuel combustion is optimized and emissions are reduced by the oxygen sensor. An oxygen sensor that fails can also cause poor fuel economy and rough idle, as well as increase emissions. Diagnostics should indicate that the oxygen sensor needs to be replaced if it is malfunctioning and the check engine light illuminates.
Oil leaks and engine issues
The valve cover gaskets, timing cover seals, or oil cooler lines of certain Sienna engines can leak oil over time, especially V6 models. Additionally, some engines consume excessive oil.
As a result of these problems, you may have to visit the repair shop.
It is less likely that you will encounter these issues if you purchase a Toyota Sienna from a reliable year. No matter what quality you buy, you’ll always have problems with your car.
