There are 1 owner-reported body & structure complaints for the 2021 Toyota Corollain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While driving my car I noticed a sloshing noise like water, I thought it was a bottle of wiper fluid until I opened and closed my passenger rear door. The door was full of water, I looked it up online and found tips to loosen a plug on the bottom of the door to let the water drain out. I did this and it was pouring out of the door. I called for service, took the vehicle in, asked about damage to electrical inside the door like speakers and locking systems. The man explained due to the way the door is made IF any water got in it would not affect these systems. They advised the plugs can get full of debris and to loosen the plugs after heavy rain. This has now happened several times, I have to check all my doors and drain them after it rains. Note there are three plug holes, all have plugs so no water can freely drain on it's own.
