Looking for the right Toyota Sienna for your needs but are having trouble making a decision? Our guide breaks down the model years of the Toyota Sienna to help you determine which year to buy and which year to avoid.
Family vehicles like the Toyota Sienna are popular because of their spacious interiors and excellent safety ratings.
Every generation of the vehicle has advantages and disadvantages because it has been produced for a long time.
Including the best to the worst Sienna model years, this guide covers them all. In addition to introducing the middle ground, the term neutral also introduces the worst and the best.
The Toyota Sienna has gone through four generations:
| 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 |
Before making a purchase decision, potential buyers need to understand the key differences between each generation.
We assessed several reliable sources of data before determining which categories were ‘Best,’ ‘Neutral,’ and ‘Worst.
In equipment reliability and owner satisfaction terms, a neutral year is one that doesn’t show any major problems. Our analysis may show that the pros and cons are about equally balanced, or simply average, according to all our factors.
Model years are listed below:
| 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 |
The following factors were considered when ranking the companies in the table above:
- Owners’ reports of reliability (surveys)
- Maintenance costs
- The safety rating system
- Consumer Reports’ ratings of reliability
- Consumer Reports’ ratings of owner satisfaction
- Inquiries, recalls, and complaints by the NHTSA
- Owner ratings on Edmunds
- JD Power owner ratings
- Kelly’s Blue Book ratings for owners
- VehicleHistory owner ratings
- Cars.com owner ratings
Some of these factors can adversely affect safety, such as recalls by the NHTSA. Recall rates are therefore associated with lower reliability scores for cars.

About the Toyota Sienna, motorbiscuit.com has reported the following problems:
Issues with electric sliding doors
A problem can arise with the Toyota Sienna’s electric sliding doors when the vehicle is manufactured between the mid-2000s and early 2010.
The majority of doors don’t work like they should. They get stuck, open and close incorrectly, or don’t work at all. Wear and tear on hinges and cables can cause it, or a malfunctioning door motor.
Dashboard cracks
Since the mid-2000s, Siennas has been experiencing a rise in this problem. In the interior construction, cracks can form as a result of these factors, which are unsightly and can indicate problems with materials. Your condition can be exacerbated if you are exposed to excessive sunlight and heat.
Oxygen sensor failure
A problem with oxygen sensors may occur in Siennas built between the years 2000 and 2003. The oxygen sensor optimizes fuel combustion to reduce emissions. Fuel economy may be reduced, rough idle and emissions may increase if the oxygen sensor malfunctions. It is normal for the check engine light to illuminate when an oxygen sensor malfunctions and requires immediate replacement.
Engine problems and oil leaks
Some Sienna engines can leak oil over time, especially those with V6 engines, because of valve cover gaskets, timing cover seals, or oil cooler lines. Furthermore, certain engines have been reported to consume excessive amounts of oil.
There may be a need to visit a repair shop if these problems persist.
Toyota Sienna models from reliable years are less prone to these problems. There will always be problems with your car, regardless of the quality you choose.
