Problem overview

Some Lexus RX300 owners report experiencing water pooling in the front floors during dry summer weather, which can be attributed to several factors. A clogged AC drain is often cited as a cause, leading to water accumulation inside the vehicle even when conditions are dry. Additionally, faulty or worn door seals may allow water to seep into the cabin, compromising the vehicle's interior. Some owners also find that blocked sunroof drains can result in leaks, while deteriorating seals around doors and windows further contribute to potential water ingress. Furthermore, dampness or moisture on interior surfaces such as seats and carpets can indicate a significant water leak issue that requires prompt attention. To address these concerns, it is advisable for owners to inspect these areas for leaks or blockages and consult a mechanic or Lexus specialist if the problem persists.
