165 reportsOur 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.
Car lunges forward when braking. This occurs at low rates of speed and is particularly prone to occur when making right and left turns. This has been going on since I bought it in 2021. Dealer laughs at me
Rear Right tail light failure due to wire corrosion rendering tail light inoperable.
This problem has been happening for a while now, over one year. When I am braking there is a jolt of acceleration. This happens frequently, and I believe this is dangerous.

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. I bought the car to drive for my safety an this is the level of safety that I am getting. Thus I am here looking for help on how I can get this matter resolved as driving knowing that airbag has failed on the passenger side is very unsafe.
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.

When applying the brakes, at lower speeds around 20 MPH my Sienna lunges forward for a few seconds, increasing speeds. This is happening frequently in school zones due to the slow speeds. Dealer told me it was out of warranty (36k or 3 yrs) and i had to pay $250 for diagnostic plus $300 for a TSB solfware reset because the Fed didn't receive enough complaints from users to make Toyota do a recall on this Safety issue. This is a major safety issue myself and many other Sienna owners are dealing with.
In certain conditions, like coasting downhill and lightly braking and then going to harder braking - there is an unintended lurch forward which requires immediate harder braking to stop the vehicle.
