To anyone one that has retrofit the cabin air filter, caution, their more than likely will be mold growth! I noticed an odor and when I cut open the compartment, it had standing water and mold growth throughout (pictures attached). I had it steam cleaned to get the majority of the growth out. GM informed me that they would not be able to "assist" me with the necessary sanitation because apparently I was the first person with this issue.
My understanding is that they have not equipped cabin air filters from ~2005 and on, so I have a hard time believing no other similar model does not have the same issue.
I have since filed a complaint with the National Highway Safety Administration, but feel nothing with come of it unless more people are made aware of the issue and report it to
https://www.nhtsa.gov/ Please, if you retrofit and notice mold growth or know anyone who may also have a similar vehicle, to post the issue on the NHTSA website so that we may all live a healthier life.
Thanks in advance.
