Toyota Sienna hybrid problems
The Toyota Sienna is a minivan manufactured and marketed by Toyota primarily for the North American market. It is named for the Italian city of Siena, in the region of Tuscany. It replaced the first generation Previa van in 1997 with a more conventional front-wheel drive layout and shares a heavily revised platform with the Camry. Both the Previa and original Sienna were smaller than the other minivans they competed against, but a redesign in 2003 (for the 2004 model year) increased the dimensions to match those of its competitors.
It was redesigned again in 2010 (for the 2011 model year). The third generation Sienna went on sale in the United States in February 2010 and is the first Sienna to ever receive a "Top Safety Pick" award from the Insurance Institute for Highway Safety. A 2020 redesign (for the 2021 model year) saw the Sienna becoming a hybrid vehicle for its fourth generation. While previous generations of the Sienna were exported to select Asian and European markets, the fourth generation is the first to be produced outside of the United States as Chinese production commenced in July 2021 by two Toyota joint ventures. In China, it is also marketed as the Toyota Granvia.
Following the discontinuation of General Motors's all-wheel drive minivans in 2006, the Sienna was the only minivan in its class offered with AWD in North America until the 2021 Chrysler Pacifica was introduced with an AWD option in 2020.
The Sienna is not available in Japan and Australia as it is not produced in a right-hand drive configuration, and the segment in these countries is already occupied by the Alphard/Vellfire and the HiAce/Granvia respectively.
As of the fourth generation, introduced in 2020, the Sienna is now built on Toyota's TNGA-K platform, which it shares with most of Toyota’s other large MPVs and crossovers.

Common Toyota Sienna hybrid problems
The 2023 Toyota Sienna Hybrid has been praised for its performance and features, but there are some common problems that owners have reported. One of the most significant issues is the long wait time for delivery, which can take 8-12 months. This delay is due to high demand and supply chain disruptions, making it difficult for dealerships to keep up with customer orders.
Another common problem reported by owners is the poor build quality of the car, particularly in the interior. The carpet on the passenger side under the front center dash has pulled away from the plastic trim, and the weather stripping around the back hatch was not installed correctly. These issues give the impression of driving an old car, which can be frustrating for new car buyers.
The front seats of the 2023 Toyota Sienna Hybrid have also been criticized for their lack of comfort, especially on long drives. The front passenger seat cannot be raised up and down, making it feel like sitting in the third row. The driver's seat has this feature, but the passenger seat does not, which can be inconvenient for some drivers.
The 12-volt battery is also a known issue in cold climates, where it can die 18 times before being replaced under warranty. The battery is undersized for the Sienna, which has more electronics than smaller cars like the Camry or Rav4. The lead-acid batteries provided with the car can get damaged and frozen easily, and they do not recharge well after their first two or three charges. Upgrading to a slightly larger H6 size battery can solve this issue, but it comes at an additional cost.
The gas gauge is another issue that some owners have reported. It can be all over the place, making it difficult to determine how much fuel is left in the tank. This issue is not a known problem to Toyota, so it is unclear what causes it. However, some owners have reported that it becomes more predictable after a few months of driving.
Finally, the 2023 Toyota Sienna Hybrid has issues with the kick sensors and the hitch. The hitch can interfere with the kick sensors and drain the battery, leaving the car stranded. This issue has affected several Sienna owners, and dealerships have had to make repairs to fix it.
In conclusion, the 2023 Toyota Sienna Hybrid has some common problems that owners have reported. These issues include long wait times for delivery, poor build quality, uncomfortable front seats, a faulty 12-volt battery, an unreliable gas gauge, and interference between the hitch and kick sensors. While these issues can be frustrating, they do not necessarily make the car unfit for use. However, potential buyers should be aware of these problems and consider them before making a purchase.
