Hi Wow - thank you so much for your information! My husband is an engineer so understands everything you have said and is going to investigate our car (when it stops raining!) We found another possible reason today. We parked the car and checked the windows were closed before we left it...but, when we came back all the windows were open by about 2 inches and as it was raining heavily the seats and interior we wet. Now we have to find out how the windows open, seemingly be themselves, when we are nowhere near the car. Will keep you posted and Happy New Year to you.

Hi I have a friend who speaks German fluently, so next time I see her I'll ask her to translate. Hope you have found the cause!

Hi Coneybiller and Energieumwandler We're not sure but we think the problem may well have been a blocked scuttle. When my husband checked, it was blocked and he cleaned it out. The carpet doesn't seem to be as wet as it was but we won't know for sure if the problem has been solved until the carpets are completely dry. One thing we have noticed is that a few times we've parked the car and when we've returned all the windows are open by about an inch. We now check the windows are completely closed before we walk away from the car. Obviously, it would be possible for rain to get in even if the windows were open by this small amount but I think we would have noticed that our seats were wet and it would take a tremendous amount of rain for the carpets to get as wet as they were. Many thanks to everyone for their advice. Will post if the carpets eventually dry out now the scuttle is unblocked or if the problem still persists and we take the car to a Lexus dealer. Sorry to hear Energieumwandler that you have the same problem (although it's good to know we aren't the only ones!) but do check the scuttles and, if necessary, clear them out. Happy New Year to all Lexus owners!

Have spoken with Lexus who say the recall for the air con grommet didn't apply to our car, so they suggest we take it to the nearest dealer, but they did say that if the dealer thought there was a problem that warranted a recall that they would liaise with Lexus Head Office. Found the last part a bit confusing but will let you know the outcome. Thanks for being so welcoming!

Many thanks for your replies. The windscreen hasn't been replaced since we bought it 4 years ago, so I don't think that can be the problem. It seems to have happened quite suddenly, so maybe the grommet in the air con is the next step. I'm going to contact Lexus to find out about the recall. Really appreciate your help - especially as I'm a newbie!!!

First post, so sorry if anything isn't quite right! Have an '06' GS300. Recently noticed mat in left rear footwell was wet. Mechanic put on ramp and checked underneath - no obvious problems. Removed mat, lifted carpet and insulation underneath was also saturated. Mechanic put it down to leaving window open in rain (usually check all windows before leaving car). Have been trying to dry it out but have now found front left footwell is exactly the same - wet car mat, soaking wet carpet and suspect insulation will be the same. No sunroof, so can't be leaking from there. Right hand side is dry front and rear. Does anyone have any ideas, please? I'm not mechanically minded but my husband is, so be as technical as you like! Many thanks.
