About six months after getting this car brand new i started smelling a foul odor. it happened every time i used the air conditioning. when i went to open the fresh air mode a moldy/musty smell emanated throughout the car. it continued and i took the car in several times to lexus. they changed the cabin filters, even used a state of the art process to eliminate the odor - but it kept coming back. they claimed it was an environmental issue. however i got an attorney who suggested i hire a mold expert and sure enough they found a toxic mold in the engine. lexus still refused to do anything about this. everyone who has been in my car smells this except the people at lexus. it is documented that the mold exists, but they refuse to admit it's probably due to a leak in the a/c system. they would never take the a/c apart to find the leak so i've had to drive this smelly car for the past 2 1/2 years....i'm going to turn it in early for fear of breathing in this toxic mold and shame on lexus for not being concerned about my health. an air conditioning expert in los angeles told me he has had several complaints about similar smells from the is. my doctor said this mold is man made and not environmental so it must be from water condensation. also, my car had several other issues like the fresh air mode would not stay open so that the water condensation could dry out. that had to be repaired two or three times. *tr
