What 2019 Toyota Sienna owners say
Most recent owner complaints, unedited.
The transmission is going bad at 85,000 miles. It’s making a whining sound when you accelerate.
2019 Sienna XLE with 77,000 miles has a UA80 Transmission is whining at the final gear per Imperial Toyota Milford MA service center. They want to replace the transmission for 9,000 USD and Toyota Corporate refuses assistance. It appear to be a common defect which could lead to transmission lockup if the gear fails.
The contact owns a 2019 Toyota Sienna. The contact stated that while attempting to open the driver's side sliding door, the door failed to completely open but remained ajar. The contact became aware that an electrical cable was hanging from the door. The vehicle was taken to the dealer, where it was diagnosed, and determined that the cable needed to be replaced. The dealer informed the contact that the door needed to be taken off and reinstalled to repair the vehicle. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure, but no assistance was provided. The contact was referred to the federal safety agency Hotline to report the failure. The failure mileage was approximately 72,000.
Started hearing a whining noise upon acceleration. Took car to Toyota for a diagnostic check. Discovered transmission is failing. Recommended repair is a full transmission replacement, quoted $10,000. After bringing to a local mechanic for a second opinion, he claims this is a widespread issue with Toyota Siennas in similar years. After some research, Toyota quietly claims there was an issue in the manufacturing of these transmissions however won’t take accountability
About 2 years after the 9/30/2019 purchase (new), the paint on the front engine hood began peeling & cracking. Calls to Parks Toyota were ineffective. Now the entire hood has pervasive cracks. The hood needs to be removed, sanded & painted with a more substantial, long-lasting paint. The paint used is supposed to contain an additional clear coat for protection.
Transmission has failed and been replaced. This is part of issues from 2017 to 2020 tranny failures, loud whining and needing to be replaced. Tranny failure is very dangerous to the occupants. Toyota has failed to warranty these.

sever transmission whine started at 138k miles over a year ago.Toyota will not fix issues under recalled ua80 transmission. Said my vin doesn’t fall within recall.
The Harness Adjuster Strap (item 5 in attached snip from user manual) loosens while in use. This item was manufactured post-recall 24C002000, using Nuna's new design described here: [XXX] This design change did not prevent the functionality of the strap to fail. There was zero to minimal debris (no food, drink, or water) in the mechanism causing it to fail. The Harness Release button (item 4 in snip from user manual) actuates freely. The adjuster strap, and subsequently the entire harness strap, moves freely, while the carseat is loaded or unloaded. I have a video available showing that the strop in the seat freely moving. We discovered the product failure while loading the child in the carseat and testing it's security by pulling on chest straps. Nuna's response was lackluster and unprofessional. Here is the sequence of events: We immediately reported the issue the first business day available, May 27th, and Nuna responded 24hrs later, informing us they would again respond in 1-2 business days to send us a form and shipping label to send back the defective product. We responded the same day asking them to expedite the process and send us a new product immediately as we had no backup for a carseat and my wife could not leave the home. A little over 48 hrs later they denied our request, and sent us the shipping and RMA form. We are now a full business week past the initial request and now are returning the carseat, with no assurance of when the replacement will be delivered.
