“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.”
NHTSA complaint #11642869, filed 2025-02“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.”
NHTSA complaint #11617592, filed 2024-10“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?”
NHTSA complaint #11641188, filed 2025-02“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.”
NHTSA complaint #11631583, filed 2024-12“At the begining of 2024, I received a recall letter from Toyota regarding the airbag malfunction. I was told to wait for a remedy by Q3 of 2024. I patiently waited and was very anxious driving my vehicle. I recently did talk to my local dealer during my maintenance and they stated that they do not have any information regarding that and that I should call Toyota. I tried calling Toyota and was instructed to wait as they still have not got a remedy and that if I was getting in any accidents Toyota will be fully responsible. …”
