POWER TRAIN
Transmission UA80e is a poorly designed transmission. It almost caused an accident due to the transmission lunching forward on its own. Also has a whine coming from the transaxle. There is a customer service program for the 2017-2018 models about this issue. But I have a 2019 and not eligible for the program. Would like for Toyota to make this right. Less than 5 year old van.

SERVICE BRAKES
During braking, when almost stopped, the vehicle lunges forward so I have to press harder on the brake so I don’t hit the car in front of me. No potholes or irregularities in the pavement. It’s just a loss of brakes. It’s happened several times now.

SERVICE BRAKES
When braking vehicle feels like it is being bumped from behind. Dealership says it is the vehicle switching from regenerative braking to normal breaking but it causes the car to lunge forward. It feels like the vehicle is going to lunge into oncoming traffic. I have to slam on the brakes to stop it. It’s very unsettling.

FUEL/PROPULSION SYSTEM
For about five months now, when we COMPLETELY fill our gas tank (2017 Toyota Sienna) even to the point of overflowing bit, the dashboard Fuel Indicator red arrow no longer goes all the way over to the right AND the "distance until empty" mileage is much less than what it should be (ie 306 miles vs approx 440 miles). We have tried the resets, which don't work. We only use good-grade gasoline.

WHEELS
We had a complete tire blowout of the rear driver tire in the desert, the temperature was 108° ambient. Toyota did not mention to us nor did the dealership that the car does not have a spare tire. We were 50 miles from any service Including cell service, I had to walk a mile to find cell service meanwhile two of our kids experience heat exhaustion. It took four hours to get the Vehicle towed. In that time our children experience heat exhaustion and had to be taken to the hospital. This is a huge oversight part to not make the customer aware that the vehicle especially family vehicle does not have safety equipment like a spare tire. In the desert this is a life and death issue that was not addressed by the dealership nor Toyota. All that is given is an inflation kit. We were not told by the dealership that a card did not come with What turns out to be essential equipment in the middle of a desert.

VEHICLE SPEED CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
When crossing a one-way road with oncoming traffic from the left, a vehicle that has recently passed might be triggering the forward collision avoidance system which cuts off throttle control to the Sienna, even when the passed vehicle is well out of the way. It is unknown if the collision avoidance feature is being triggered as there are no warning lights or messages in the display. This results in the Sienna having no accelerator response and sitting “dead in traffic” sideways in front of oncoming cars. This this is the second time this issue has occurred and today I was nearly t-boned by on-coming vehicles as there was no throttle response to move the car forward. This issue has been reported in 4th generation Sienna (‘21-‘24) forums on Facebook. This issue puts at risk vehicle occupants as well as other vehicles on the road.

UNKNOWN OR OTHER
I am contacting you regarding Toyota Warranty Enhancement Program – ZE6. This concerns sticky and cracking dashboard and glare from this. I had no idea this existed. I own a 2006 and a 2010 sienna. I have not received any mailers from Toyota regarding either Sienna's . My van's dashboards are included in this program. Problem is, I never received notice from Toyota about either dashboard. Is there anything that can be done about this?

STRUCTURE:BODY, LATCHES/LOCKS/LINKAGES:DOORS:LATCH
Pressed the button to open the rear passenger sliding door and it would open. When opened manually it would open only about 12 inches. Then when we were driving on the highway the door opened on its own. The door had to be manually closed and now it will not open. This is now a safety concern that in the event of a crash passengers may not be able to exit the vehicle or the door could open again while driving.

ELECTRICAL SYSTEM
Passenger side sliding door randomly opens even when car is in the locked mode and when parked. It has happened 4 times. Toyota blames my chair lift and the mobility works blames Toyota. Service has not been able to recreate the problem since it is intermittent and has documented the complaint. However the only way to insure it doesn’t happen is to shut off the power to the doors making them difficult to open. This has only happened while parked but is a safety issue when not at home in the garage.
