My story: Bought my pre-owned 2008 Package 6 Touring on July 3, 2009, with 13k miles on it (in Southern California). Went to the doctor's office on July 14, 2009 for breathing difficulties. Been back to the doctor's 6 times since then, all for breathing issues. They could not find the right diagnosis after many tests (eg: upper GI series, asthma, sinus CAT scan, etc). Last week, I turned on the car in the hot sun and the AC blasted into my face. It smelled very much like opening my gym bag after forgetting that I had left my wet towel in it 2 weeks ago. I looked in the AC vents and saw what appeared to be mold growing on every vent (I've posted pics of this on my flickr page, so contact me directly for the link). I did some research and found all the threads about stinky Priuses. And then I found all the disturbing anecdotes about mold on the evaporator coils and bad odors, etc. Luckily for me, I bought the car with a Toyota Certified Warranty, so I took it in 58 days after purchasing it to get it checked out. They claimed that the white splotches on the AC vents are not mold, that it was actually Armor All from a bad detail job. I really don’t know, but to me, it looked and smelled very much like mold. Anyway, without much argument, the service manager agreed to replace the entire evaporator unit, per an official Toyota Service Bulletin. I had never heard of that particular TSB before, so it was surprising to me. I asked for a copy of it, but obviously, they didn’t want to release it. He did mention that the TSB just came out about a week ago (it’s 09/03/09 as I write this). The fact that Toyota would agree to perform such a huge job tells me that the problem is pretty serious. They covered my rental for the two days they worked on my car. Additionally, I asked them to replace the cabin air filter (for free—but had to fight for it; otherwise, it's $30). I argued that I would NEVER have bought this car had I known about this in the beginning. Ever since I discovered the “mold(?)” on my AC vents, I stopped using the AC. My breathing issues have subsided, but I don’t know if that was the reason. All I know is that I have improved a bit, and we’ll see if I will fully recover. All evidence for my breathing issues points at the Prius: July 3: Bought car July 14: First doctor's visit for breathing issues July 14-August 27: Breathing problems grew worse August 27: Found what appeared to be mold in AC vents August 27-Now: Stopped using AC in car, breathing improved slightly Anyway, the TSB on my invoice is listed as: Replace Evaporator Sub – Assembly. T – SB – 0261-09. Here are all the parts: Quantity: 1 – 88501-47041 Evaporator Sub-As Quantity: 2 – 90068-14010 Ring, O Quantity: 2 – 90099-14119 O-Ring Quantity: 1 – R134 ? Hope this helps someone out there. Google "AC mold prius" and a few helpful sites will come up, especially one from thesqueakywheel. As much as I love my Prius, mold spores pose a very dangerous health hazard to some people, and in my case, I've been suffering quite a bit. A class-action suit doesn’t seem too farfetched. Good luck. -------------------------------------------- It's now Sep. 6, 2009. I got my car back from the dealership on Sep. 3. The day after I picked it up, a got a warning light while I was on the road. "P/S error" and "VC" or something like that. The red triangle with the exclamation point stayed on, as did the car/exclamation point on the navigation screen. The car thought the emergency brake was applied, even though it wasn't. Overall, it was still driveable, so I drove it to the dealership on Sep. 3. They couldn't find anything wrong, said something about the "codes" showing 2 circuit issues, but that nothing was wrong with the circuits, so they just reset the warning lights and turned them off and sent me on my way. Oh, the front cigarette lighter also stopped working after they put in the new e-coil. They couldn't fix this right away, so scheduled for me to come in next Tuesday to get that taken care of. Today, as I was driving around town, all the same warning lights came on again. I'm done with this car.
