“We had our van parked on a driveway with a front facing slope, we had hard rains went we where going away there was water coming out of the seat belt on the passenger side and the panel above the window was stained down to the window support where the air bag is. I've been reading reports as far back as 2008 we have a 2020, went taken to the dealer they want 1000 to 2700 to remove the head liner and try to fine the problem, which what was reported didn't help. The dealer recommended to not park with the front of the van facing down hill if rain is forecast, my problem is that Toyota has not been required to fix the leaks. I'm calling my local dealership tomorrow about are leak.”Owner report · Air Bags · Jun 2026
“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.”Owner report · Power Train · May 2026

“A catastrophic failed automatic transmission; UA80E of Toyota Sienna 2020 at 85,000 miles. It occurred while I've been driving downhill. No warning lights, not overheating, no diagnostic ODB code, no other indications prior to the failure. Failure created a substantial safety risk for myself, my four passengers and other road users. Sudden loss of transmission function could lead to potential dangerous situation. Minivan was towed to the nearest Toyota dealer where transmission assembly was confirmed for replacement.”Owner report · Power Train · Aug 2025
“"I've owned the vehicle for five years, and recently I started hearing a whining noise coming from the transmission. After doing some research, I discovered that I'm not alone in experiencing this issue. The dealer told me that the transmission itself is the problem and recommended replacing the entire transmission. However, a second opinion suggested that this kind of noise isn't normal. I'm worried about safety because, although it's just a whine right now, I fear it could fail unexpectedly. I have a child in a wheelchair, and ensuring my vehicle's safety is very important to me."”Owner report · Power Train · May 2025

“The passenger side rear door unlocked and opened by itself in the middle of the night, no warning messages were given previously, doors were locked that night. Keys were not accidentally pressed on.

“Spontaneous and random: Blinkers come on, radio volume goes up or down when turning the other way, CarPlay USB shuts off and on, hiccups when accelerating (when ECO kicks on/in)...everything points to an electrical/computer issue. Purchased used from a dealership and noticed these issues after the 3-day return window.”Owner report · Electrical System · Dec 2023
“Speakers make an ear piercing loud noise that lasts about a second. If this sound were to occur during travel, could cause distraction leading to harm, or with young kids in the car, possibly damage their ears. This problem has been random and not experienced by a dealership. No warning messages or symptoms to the problem. Problem first appeared 6 months ago.”Owner report · Electrical System · Oct 2023
“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.”Owner report · Service Brakes · Aug 2023
