For nearly a year I've been noticing an odor in the car that just keeps getting worse. It is a nasty, musty odor that could knock you out! It is so bad now, I can't even drive the car. At first we thought there was a dead animal stuck in the vent ducts or something. We took it to have it checked out and nothing was found. Finally, I decided to check online. I should have done that to begin with. Apparently I'm not the only one with this problem. It appears to be the air conditioning and heating system. Condensed water gets trapped inside the ventilation system and grows mold and mildew. (Something like that.) How wonderful to inhale mold and mildew spores everyday. So I contacted Chrysler. My car is no longer under warranty so there is nothing for them to do about it. This isn't a warranty issue. No component issue here, rather a design issue that should be recalled for repairs. This can potentially cause health problems. Chrysler was fully aware this problem existed and they should be held accountable. Not only clean and deodorize (if possible) the air conditioning/heating system, but find a better way for the system to drain completely and dry itself out. Now I'm stuck with a beautiful car that STINKS! Nearly $25,000 for this fully loaded stinky, useless vehicle. I'll never buy another car from Chrysler. I'll bet the new PT Cruisers are exactly the same way and those people will be screwed in a year or two.
