Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“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. …”

NHTSA complaint #11554727, filed 2023-11

“There is a rattling that comes from the 2nd row seats. It is loud and driving me crazy. I see hundreds of complaints on Toyota forums but Toyota will not acknowledge the issue, sounds like I am driving a clunker instead of a $35,000 car. I purchased new and this has been going on for seveal years”

NHTSA complaint #11034515, filed 2017-10

“The contact owns a 2012 Toyota Sienna. The contact stated that when engaging the brakes the front driver seat would slightly slide forward. The vehicle was taken to the dealer who stated that the vehicle was performing up to manufacturer specifications. As a result, they did not offer any assistance since they were unable to alter the design of the vehicle. The vehicle was not repaired. The approximate failure mileage was 12.”
