2 Air Bag problem

Failure Date: 01/01/2021

Water intrusion from front sunroof when vehicle is parked at a 5% grade with the nose downward. Multiple vehicles exhibit this issue. Toyota is not creating any TSB and will mot even remedy it even if we have an extended warranty. Here is a link to the discussion thread: [xxx] I have not posted on this thread but I have the exact same issue for years. Toyota dealerships want me to first pay $1000 in labor to pull down the headliner and test. Then ask the warranty to cover the assembly, if they don't cover it. . . Then I am on the hook for the work. The missing seam sealer is a common issue that will not manifest inside the 3yr / 36k mile warranty. My issue started around 2020 that I noticed and every dealership would not help me other than place a large burden on me. This can impact the electrical and the airbag curtains. The issue needs to have a seal sealer added to the sunroof assembly as the fix. As a family vehicle, this is a dangerous issue for multiple occupants in a single 7 or 8 person hauler minivan. Please ask Toyota remedy this issue that has been going on for over a decade. Please ask them to stop forcing customers to have sunroofs and panoroofs. . . When they can't build it correctly.

I had a front damaged car accident in 2016. I realized that none of airbags were deployed since I was asked by at fault driver's insurance attorney. I was driving on a local one way road and a car showed up in front of me all of a sudden. It was crossing in front of me as ignoring "stop" sign on his side. It was too close to avoid and brake was not helpful.
