We recently had our highlander completely totaled by our insurance after a failure to have our air conditioning drain properly. The clog caused water to back up into the frame of the car and flood our floor carpeting. The drainage issue also caused the headliners to become wet and drip onto the leather upholstery. We brought this to the attention of the dealership advantage Toyota valley stream and they first suggested clearing the moon roof but that wasn't the issue. When we brought it back to them they knew it was a problem with the A/C drain. This appears to be a known issue with Toyota vehicles. Even though this is a known problem it's not part of their standard maintenance process. We could have saved ourselves a headache by having them "add" this to the regular maintenance.
