What owners report

The last week of September 2021 my husband notice a sound like water runing and a leak on the driver and passenger seats, we take the vehicle to the Dealer for an inspection on October 2nd. They said the AC hose was clogged for a spiderweb and the leak can create a mold. This mold can affect my family health. We informed to the insurance and we taked the vehicle to the Dealer for repair. They did an expensive special cleaning to Remove the mold, and disamble my entire vehicle, the worse is my vehicle still unassembled after 3 months at the dealership. All this happens with out any warning sign, symptoms or light. This vehicle is 3 years old and all services on time and by the same Dealership. My vehicle has a lot of technology but not warning about this AC clogged and damage my entire vehicle wich still on repair.

2018 Sienna · Oct 2021

3rd row power seats are malfunctioning and are operating while vehicle is in motion. Multiple times, and on different days, the power seats have started to close while passenger is seated and buckled in the seat. Occurred today while on the highway, at highway speed while my wife was seated in the drivers side 2 seat split. The seat started to close on its own - no one touched any button and we had been driving for over an hour. The seat put pressure on her until it stopped in a partially closed position. The seat buttons then did not work to reopen the seat back for several minutes. This would be extremely dangerous for a small child. This has happened in a similar scenario on multiple occasions and we are certain that the power seats are malfunctioning.

2015 Sienna · 15,000 miles · Jun 2016

There are 2 problems I am experiencing with my 1 yr old Toyota 2013 Sienna van - 1> rattling noise coming frm back of 2nd row or 3rd seat - very hard to pinpoint source, took it to my dealer for 25K svc, explained, was notified they will run this check on my 30K mileage svc as van needs to be left for 3 to 4 hrs with them. There are a lot of internet blogs and postings on this issue, with some getting Toyota to replace 2nd or 3rd seating completely with a brand new seat and thus making noise disappear 2> when turning the steering wheel, whining noise in the background can be heard at very lo w speed around 15-25 MPH or even less, very annoying and disturbing for any car driver.I believe that is May also signify an underlying problem, waiting to get out of control. With a range of moving parts working in tandem, it is difficult to figure out the source of such abnormal car sounds. …

2013 Sienna · 25,000 miles · Apr 2014

This has now occurred twice and has been repaired multiple times. The 1st time happened a few weeks after being purchased. I was traveling approx 45-50mph, began breaking for a yellow light when suddenly the woman in front of me stopped short of the light. To avoid hitting her I had to break firm but not slamming on the breaks. I stopped about a car length short of her and then felt an impact. I assumed I had been hit from behind by another driver but there was no car there. I pulled into a mall just ahead and looked behind the drivers seat to find the 2nd row seat, where 10 minutes before my daughter had been sitting, had collapsed forward, slid on the rails and slammed into the drivers seat. The seat was locked and unable to be moved in it's collapsed position. I suffered extreme whip lash and back pain. …

2013 Sienna · 40,000 miles · Nov 2015 · 1 injury

The third row passenger side split was stored and then put back up. Upon lifting the seats, pieces fell out (spring, washer, and screw) and the locking mechanism would not lock the seats into place. I am not sure how long these parts were loose, but it is a major safety hazard as the vehicle seat was not secured to the car as intended. We plan to to follow up with Toyota, but upon investigating, it seems that this is an issue for several 2011 Siennas. My Sienna was manufactured 4/2012. This is the smaller of the split seats, but out of an abundance of caution, we don't plan to use the 3rd row at all until a remedy is produced. Unfortunately, I saw only consumer complaints in regards to the 2011 3rd row seating issue and didn't see any solutions.
