My Toyota sienna is a 2020, has 83,000 miles and has recently been squealing when I accelerate. I took the van to a local body shop and they said it seems to be my transmission. I called Toyota immediately and they knew that the transmissions were faulty and that they would try to work with Toyota to get it fixed. There is no way I can pay 9k for a new transmissions because they put in faulty ones.

The brake peddle is too small, it feels like my foot is going to come off of it or miss it. Some time's I lose a second or two trying to locate it with my foot, very frightening, and dangerous Every vehicle I have ever owned had a brake peddle twice that size. Yes it's a mini van, but the brake peddle does not need to be mini. This vehicle can carry 8 adults with lots of extra room, it should not even be classified a mini van. The brake peddle is less then 4 inches wide. Please look into this dangerous issue. Photos attached.

Is 38 complaints a lot? They were filed between 2019 and 2026, roughly 6 a year, which is fewer than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2020 has 38 complaints on file, fewer than the 2019 (45) and fewer than the 2021 (157). Of the 13 model years of the Toyota Sienna we cover, the 2011 has the most (614). Older model years have had longer to collect complaints.
