NHTSA Complaint #11493244 — 2020 TOYOTA COROLLA

I’ve owned my 2020 Toyota Corolla since April of 2019. Around June of 2022 I noticed a sloshing/ swooshing sound. I didn’t think much of it, but it kept doing/ hearing it. Finally I got tired of hearing the noise, and started to look for where the noise was coming from. I then realized there was water in my rear doors. I didn’t know what to do since once I realized what was happening or how it was happening, my warranty period had just passed, since at this point I have owned the vehicle for over 3 years. I kept researching and found the article attached in pdf. I was able to complete the work myself. At this point I am now worried the interior will have rust, since the water would sit there for days/ weeks after it rains. I think this resolves the issue of getting the water to exit the doors, but I don’t believe it resolves how the water is entering the vehicle. I truly believe this car will rust out from the inside, and will be left paying for the bad manufacturing of Toyota, with regards to this vehicle, and possibly a dangerous vehicle issue, as the rust will compromise the integrity of the vehicle.
