I have a 2018 premier and last summer during rain season (FL) my equinox flooded. Back floor was sopping wet, spare well full of water, it smelled so bad and the windows wouldn’t defrost after it rained and with this Florida humidity I had to defrost and dry off the windshield for at least 20 mins before I could drive. I took it to the dealership and finally the third service mgr I worked with knew exactly what it was. The gutter system for the sunroof had been clogged. He explained that the sunroof is not meant to be waterproof and there are gutters that run down the body of the car behind the door pillars and are supposed to drain all excess water that the sunroof can’t keep out. He asked me if I park under any trees. Of course I do, I look for shade in every parking lot, it’s HOT here! Well, apparently the crap from the oak trees I parked under every day at home AND work clogged the gutters and the water had nowhere to go so it came into the car. He walked me into the shop where there were 3 other equinox taken apart and drying..
At least I finally had an answer.
This was quoted between $1100-2500 depending on what kind of mold was found and what needed to be replaced. It ended up costing me $1400 as he worked with me and felt bad because the other service dudes I worked with treated me like I was stupid. They took the interior out and dried everything out, replaced the jute rug under the carpet in the entire car and ran an ozonator treatment through the vent system 3 times and replaced all of the interior filters because everything had mold growing.
Now it’s rain season again. I have NOT parked under a tree for an entire year and it’s doing it again and smells like mold and musty mildew. It’s baaaaack
My service mgr is not working there anymore and I’ve left 2 messages for his replacement. I’m not dropping one more white hot cent into this issue.
