You purchased a 2021 Toyota Sienna and were not informed at the time of sale that it had an active safety recall (23TA15) affecting the airbags. You only discovered the recall months later when trying to list the vehicle for rental, after already driving it across state lines with your family. Toyota did not provide you with written confirmation of when the recall became active or give you proper warning before you used the vehicle. The recall prevented you from using the vehicle for its intended business purpose while waiting for the repair to be completed.

Your 2021 Toyota Sienna's airbag sensor failed to work properly at around 30,000 miles. Toyota issued a recall (Campaign 23V865000) to fix this, but the replacement part wasn't available when you needed it. The manufacturer told you to stop driving the vehicle but didn't offer any other help or timeline for when the part would arrive. The repair will likely involve replacing the faulty airbag sensor with an updated one from Toyota.

You were not notified promptly about Safety Recall 23TA15 for your 2021 Toyota Sienna, which involves the airbag system. This delayed notification exposed your family to a safety risk while you were unaware of the problem. The recall may require inspection or replacement of airbag components to ensure they function properly in a crash.

You purchased a 2021 Toyota Sienna in June 2024 and were told an open safety recall (23TA15) would be fixed soon, but over a year later no repair has been offered. Toyota's own timeline indicates the repair should be available in Washington State, but dealers keep saying no fix exists yet. This leaves you driving a vehicle with unaddressed safety concerns.

Toyota has been aware of an occupant classification sensor defect since at least December 2023. Their automated systems state the remedy should be available by 2024 Q3. And yet we were in Feb 2025 and no remedy is available. I don’t think they intend to fix this at all, leaving me with a car that is not safe to use the passenger seat.

Recall 23TB15 was issued on Dec. 20, 2023. The remedy was supposed to be out by the 3Q24. I just called dealer service, and there is still not a remedy out. I am driving a car without knowing if the front passenger seat airbag would deploy in an accident. This is unacceptable to go this long with no corrective action plan yet issued. Can you take any action to get the manufacturer to correct this defect?

Our SRS airbag warning notification went on suddenly for no reason we could ascertain, and we're having to get it repaired outside warranty. The van has around 80,000 miles on it, but is only 3 years old.

My 2021 Toyota Sienna has had an open and unrepaired recall for airbags failing to deploy since the beginning of the year. I been unable to use my vehicle because of this. They have pushed approximate date of the fix being available into next year which is unacceptable. A safety concern like this should be dealt with promptly.

There is a recall on the passenger side airbag sensor of this vehicle. The time it is taking to get it fixed is UNACCEPTABLE. Toyota makes new vehicles with working components. They care more about money than lives. Since the recall includes the air bag, people will die before this gets fixed. Toyota's solution is to tell us to not use the front passenger seat. That is ridiculous; this is a family vehicle and all seats are needed. We have contacted Toyota twice in which we have been advised to rent a car - for 2 years - and we will "probably" be reimbursed - after the recall is all fixed. We do not have the space for another car or the desire to put that much money up front into a rental car. We could sell the van and buy a newer one but would lose a lot of money in doing so, nor could we in good conscience sell this vehicle to anyone else. In our latest conversation with Toyota, we were told that the first customers to have access to the recall fix would be this September, but since we live in Utah, it would not be available to us until 2026! What? That is DISCRIMINATION. If the fix is available, it should be given to all who need it. I can't believe how Toyota is treating their customers, especially when the recall can be life-threatening.

This recall has been open for 7 months and a remedy has still not been issued - this doesn’t seem reasonable for a safety concern. I have also several times experienced a failure in the “extra” 8th passenger seat (middle row middle seat) sensor - it alarms that the seat belt isn’t buckled even when that seat is not in use and not even installed at the time.

Keep in mind: BRAND NEW SIENNA!!! 1. What component or system failed or malfunctioned, and is it available for inspection upon request? -The main and MOST important component was the ENTIRE airbag system which displayed "malfunctioned" ONLY AFTER the collision. The TPCS (Toyota Pre-Collision System) also was defaulted to "OFF" and said that the sonar malfunctioned. 2. How was your safety or the safety of others put at risk? -VERY COMPROMISED! My whole family and my children would've been seriously injured or departed from this world had we not had the seat belt on and the way it all played out! All of the airbags, including the driver's knee airbag, passenger seat cushion airbag, front seat side airbags, rear outboard seat side airbags, and curtain side airbags for all three rows , malfunctioned and car was in a standstill on the fastest left lane #1 on I-95 with no cushioning or failsafe mechanism active 3. Has the problem been reproduced or confirmed by a dealer or independent service center? -NO, and Toyota was very quick and desperate to get their hands on my vehicle and to get me to sign their authorization instead of wait. As a computer scientist, I know when information systems can be exploited/manipulated and all my driving data and accident/metadata is collected constantly by Toyota so in short: "NO TRANSPARENCY" 4.Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -YES, two very biased partisans involve: The liable party's insurance (AllState) and Toyota Motor Co. So I need some nonpartisan assessment/evaluation ASAP 5. Any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -Nope! NO warning lamps, NO vehicle health messages, NO Toyota App notification PRIOR to the accident. Everything mentioned in the last sentence went haywire EXACTLY AFTER the collision and displayed lamps/played warning alarms non stop. Refer to uploaded files.
