All interior dome/lights (door side lights, visor mirror lights, all overhead passenger lights, etc) not lighting up at all. Fuse in engine compartment is good. Vehicle has been at auto dealership where originally purchased. Safety concerns are that at night, unable to determine if there has been access by person or if person is actually in vehicle. Vehicle diagnoses was begun on 6/12/2023 and is still in process of issues. Received a call from the service representative on 6/19/2023 that water had accumulated under the fuse box in the engine compartment causing corrosion at the connection of the wire harness to the underside of the fuse box. Initially this caused the the internal lights to fail. There is much more corrosion occurring which will eventually cause a complete electrical failure and possible engine failure/fire. Current recommendation from service manager is to completely replace the wire harness at a cost of $7,000+. Insurance may or may not cover the cost of repair. The insurance adjuster is meeting today with the service manager. In my opinion, this is a serious defect in Toyota Sienna manufacturing, design and materials used.

We got into an accident today, and none of the sliding doors would not slide open. It would not even allow us to pull the doors opens. The vehicles electrical was damaged, but that should not prevent the other doors from opening. This is a very bad situation if someone is needing to evacuate the vehicle. The rear passengers would be trapped. Please address this issue with Toyota asap. People who usually have Vans have big families and small children. This would be a very bad situation if vehicle needed to be evacuated asap. The rear passengers would be stuck.

The vehicle rear sliding door had a recall. I had the recall preformed at Smithtown Toyota. After the correction was done. I continue to have same issues with the drivers side rear sliding door. Where it will not open when pushing the open button on my controls in the front. Or when my child 12 years old attempts to manually open the door. As this does not happen all the times. The dealer says they can not replicate the problem and it is working to manufacture standards. I spoke with Toyota corporate and they are aware of continued problems with the sliding rear doors. the have a customer support group, but I would have to pay for the dealer to inspect the vehicle. I have extended warranty so they said I wouldn't then have to pay. However every time you take it in with a problem they can never replicate the problem. They are not the only dealer with this response. It must be a set line throughout all brands as its always that answer until your warranty expires. When it expires then all of a sudden they can find all problems and fix everything.

Driving 35-55 mph and going around (usually) a left curve on the highway or interstate, van suddenly brakes, swerves, and traction control/vehicle stability control light pops on. Whole episode lasts a second or two, then its fine. It wont happen again for the duration of the trip. I only drive the van on weekends, and it has happened three times in the past two weeks. It has nearly caused a serious accident.

At various times, the sliding doors will not close when the power button is on. I have received a card to get this fixed as sensors need to be replaced. The vehicle is stationary in a parking space. It is happening more often now.

Van would reboot while parked or driving. It started with dashboard rebooting then I couldn't start the van. There was a time after driving I put the van in park and turned it off but my van was moving on it's own. I always call the dealership when the rebooting occurs. I was told either it was a software issue or since the problem went away, I should be fine. Well recently when my van stalled and had to be towed to the dealership. I was told it was a battery issue and the battery was replaced. When I picked up my van and went home, noticed my rear view camera would not come on went I put the van in reverse. Called the dealership to tell them what's going on and the service advisor woman was very rude and stated it was battery and they never checked anything else. I stated to the woman the I've always expressed my concerns about the van rebooting, won't start, or moving on it's own. The woman became very rude and hung up on me. I decided to go right back to the dealership on the way there I called back to speak to the manager of service department to explain what's going on. While driving there the check engine and another light turned on. Shortly after that as I was turning left, while in the middle of the intersection my van stalled. The steering wheel and brakes locked and the van completely shuts off. I was locked in my van with no control over the van and it was moving towards a pole. Luckily the van stopped before hitting anyone or anything. I was on the phone with the service manager the entire time. The manager called for someone to pick me up and called a tow company. I asked the manger if they are stating my issue was a battery and a new battery was installed why am I still having the same issue. The police was call because someone reported my van in the middle of the intersection.

2015 Toyota Sienna. Consumer writes in regards to vehicle fire.

- Lakewood, NJ, USA

When I get into the Sienna in a parking spot (stationery) and twist the key in the ignition the vehicle starts but the electronic steering does not work. This happens intermittantly. I have to sit there and let the vehicle run for awhile before the steering kicks in. The steering wheel is basically locked and difficult to turn. My greatest fear is that the steering wheel will lock up on me while I am driving and will not be able to steer.

Passenger side power sliding door constantly malfunctioning. It opened after a bump while traveling 65 mph on the interstate. We had to pull over to close the door. It also deployed the wheelchair ramp while moving because the power door is the same side as the ramp.. make the manufacturer fix it or make the wheelchair conversion company fix it. Somebody needs to fix this before somebody dies! all this red tape and zero action is insane. People are getting injured while the finger pointing is happening. When will something be done" how many injuries have to occur before an action step occurs"

2015 Toyota Sienna mini van bought new. Still covered by 36 month warranty with 30,000 miles. Power sliding doors under recall. Observed significant rust on metal plate bolted on door hinge covering electrical wires. If metal cover rusts thru, could lead to short and electrical door motor failure. Toyota refuses to replace metal cover plate. I feel Toyota should honor warranty and replaced rusted parts.
