The guide gives you a detailed overview of all Sienna model years, from the best to the worst. It also introduces a middle ground called ‘neutral’ that represents the middle ground between the best and the worst.

In order to make an informed decision, potential buyers need to know how each generation differs in key ways. Based on a comprehensive review of data across several reliable sources, we’ve categorized model years by generation into ‘Best,’ ‘Neutral,’ and ‘Worst’ categories.

A neutral year represents a model year that does not display significant problems or excel in terms of reliability and owner satisfaction. We could find that they are evenly balanced between pros and cons, or that they are simply average based on all the factors we took into account.

The model years are categorized as follows:

Electric sliding door troubles

The Toyota Sienna’s electric sliding doors are convenient, but they can suffer from issues if they are manufactured between the mid-2000s and early 2010, particularly in the mid-2000s model.

Dashboard cracks

The problem has been particularly prevalent in Siennas since the late 2000s. The cracks caused by these factors can be unsightly and reflect deeper issues with the durability of the materials and the quality of the interior construction. It is possible to exacerbate this problem by exposing yourself to intense sunlight and heat.

Failing oxygen sensor

There is a possibility of an oxygen sensor failure in Siennas, particularly those from the mid-2000s and the early 2000s. The oxygen sensor optimizes fuel combustion and reduces emissions.

In addition to poor fuel economy and rough idle, an oxygen sensor that fails may also increase emissions. The check engine light should be illuminated if the oxygen sensor is malfunctioning and diagnostics indicate that it needs to be replaced as soon as possible.

Oil leaks and engine issues

It is known that certain Sienna engines, particularly V6 models, can develop oil leaks over time, usually caused by the valve cover gaskets, timing cover seals, or oil cooler lines. In addition, certain engines have been reported to consume excessive oil.
