 I bought a 2016 Correll 5 months ago and have had nothing but issues with the a/c system. There is a mold smell coming out of the vents. I have taken it to my local dealer 3 times in less rhan a month and they are trying to tell me to just deal with it and they cant get the smell out. This is a known issue with the Corolla's per the shop manager at toyota.  Just another note. There a certain instructions on how to shut the a/c systems off (make sure you follow it).  Even though i have and it did not resolve my issue. I cant wait for the summer for it to get worse. I doubt i will ever buta toyota again. Expecially a corrola.
