The 2022TOYOTAREDUNDANT SIENNA carries 160 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 8 crashes, 0 fires, 3 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2022 REDUNDANT SIENNA is service brakes with 62 filings, followed by electrical system (12) and seats (9). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 51 investigation files overlapping the 2022 REDUNDANT SIENNA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is currently being inspected by local Toyota dealer.

The 2022 Toyota Sienna temporarily accelerates or surges forward while braking, or has a momentary loss of braking / deceleration before it re-engages in braking.
The wiring harness connector for both lights has had water accumulate in the connector which causes the rear tail lights to fail. Both of my tail lights have failed, and the cause was corrosion inside the wiring harness connector. I had to replace the wiring harness and connectors on both sides, driver, and passenger And I had to pay out-of-pocket. The dealer said that this problem is common on 22 sienna's and I have seen other 22 sienna's with out their driver and passenger rear running lights burnt out.

For over a year now, I have been experiencing a random issue in my van with the brake system. It feels like a slippage when I hit the brakes to slow down and it will randomly feels like something slips and just give gives out and gets loose and like you are free falling until the brakes grab and actually stop. I have had it in the dealership twice to fix this issue. Last year they reprogrammed the brake actuator assembly control module, and it worked for a while, but then once again after several months, it started again and the second time I took it in they drove it around to try to get it to mimic the problem, but was not able to so Couldnât do anything about it and just said to watch it and see if it became more frequent. They also said that once you have the actuator reset the computer shows updated and canât redo it.The problem with this issue is that it is random and sometimes itâs less and sometimes more and I canât give specific dates because of the randomness of the pr
Brakes release briefly when slowing to a stop. While slowing to a stop with steady pressure on the brake pedal, the braking action will momentarily give out, resulting in the vehicle lurching forward beyond the anticipated stopping/slowing distance before the braking action re-engages. This has resulted in near collisions with cars, bikes, and pedestrians as the vehicle suddenly stops slowing without warning and unexpectedly increases stopping distance. The problem is intermittent and difficult to reproduce, but has occurred repeatedly over at least 6 months of ownership. No warning lamps, error messages, or other related symptoms from the vehicle either before or after occurrences of the problem. Has been taken to the dealership for an update to the vehicle but it didnât fix it. There are multiple reports online and multiple lawyers talking about this.
Pre-Collision System Malfunction, Hybrid System Malfunction, AWD System Malfunction suddenly when restarting the vehicle. Towed to Toyota of Downtown LA dealership. Toyota of Downtown LA Service tells me that the CPU on my relative new Sienna 2022 was fried from jump start when Sienna starting-battery was low. It was done by a AAA professional, I doubt that is the reason for the fried CPU. I believe Toyota engineers would not design/allow the CPU vulnerable to being fried from a jump start. This is a horrific design flaw if it is this way. This happens now, just 6 months after the 3 year warranty coverage. Toyota of Downtown LA Service is telling me it is going to cost me $2900 to replace this CPU. I find this unacceptable.

The Entune 3.0 System governs navigation, calls etc. The system on my car has been replaced 4 times and still does not work. This is a life safety issue as the system grabs phone calls while driving without being able to answer. It also makes it frequently impossible to use hands free on the phone as it grabs calls. In order to avoid it grabbing calls I have to disable bluetooth on my phone which then causes my phone to not work in handsfree mode (ok google etc.) Furthermore the backup camera does not always work. Finally, a Toyota Service Manager told me in his oppinion 25% of the entune units are "bricked," non functional and need to be replaced. Toyota has fired according to him Panasonic as the supplier and now has a new provider.

When braking and coming to almost a complete stop, the vehicle will randomly lurch forward. This situation has caused me to run stop signs and almost hit pedestrians on crosswalks. This failure has been independently observed by myself, wife and mother. The vehicle did not display and warnings prior to the failure. The vehicle has not yet been inspected or reproduced by a third party.
