Problems with 2011 Toyota Prius ENGINE AND ENGINE COOLING

The air conditioning system in the prius is defective. it is prone to growing mildew and/or mold in the system, which results in toxic air being pumped into the car. i have reported the problem to my local toyota dealerships several times, and they have been unable to fix the problem. there is a large body of information about the mildew problem online which seems to indicate that this is a common problem among prius from 2010 to the present. since noticing the mildew smell in my car, i have had severe allergy problems. this is a serious safety concern that is adversely affecting my health, and given its prevalence among cars of this make and model, i believe toyota should have to address this problem immediately. the air conditioning system flush does not fix the problem, and in fact may have made it worse. *tr

The car suddenly decelerated from 65 miles an hour to about 5 miles per hour while driving on a highway at night with the shoulder blocked due to road construction. this same problem was present in the 2004 prius and was apparently the subject of nhtsa investigation. there was a recall issued on november 30, 2010 for 650,000 units of the 2010 prius. toyota has not been able to determine the cause of this problem in the earlier models and admits it doesn't know the cause of the problem in the 2011 prius. this defect presents a great danger, especially when driving in heavy traffic at highway speeds. *kb

Upon ice start up at times, there is a loud knocking noise emanating from engine compartment. goes away after 10 seconds and car drives fine. has occurred several times. though there is a tsb issued, dealer would not fix unless issue is replicated despite showing them what my car did on video. most noticeable after car was run for a very brief time hours before. also notice the last few weeks, while driving vehicle, upon ice starting up, the engine is rough and the shift to ice is noticeable. previously it was smooth. no codes have appeared and the car appears to run normal otherwise. i would like the dealer to fix the problem as described in 2 separate tsbs (engine mounts and intake manifold gasket). *tr

Upon starting vehicle, a very loud knocking noise, accompanied by shaking occurred. at this time no failure/warning lights appeared on dashboard. moved car forward approximately 15 feet, and placed car in park, knocking/shaking did not abate. turned car off. the next day, the car, upon starting had the same loud knocking/shaking. it was audible from several feet away from the car. on the second time, it was accompanied by a warning light to put the car in park. vehicle was towed to the dealership. *tr
