Left Rear Puddle
Hi folks. I've got a '22 GLS 450 which I love, but I'm wondering if something is wrong. Whenever I drive it on wet roads and then pull it into my garage, a large water puddle forms on my floor below the left rear corner of the vehicle. If I sweep it away, another puddle forms and it takes 2-3 times before no more water drains off the car. I can't tell if this is water running off of the wet car, or if it is coming out of the body interior, which would not be good. Has anyone had similar occurrences and if so what was the resolution? Thanks as always!

My guess it's just drainage because your garage is probably sloped slightly out. Try reversing into your garage and see if the puddle occurs on the opposite side. If it's a 2+ car garage, try parking in another slot.

Could be condensation from the exhaust in addition to the water. As Wildta said it could be an issue with the grade of your garage you never noticed before causing it to travel to the left rear before dropping. If it truly is water those are probably the only plausible answers. Depending on how curious you are you could setup and old iphone or ipad under there and let it record and run the video back and see if you can get a better idea.
I have the same year and model and it does create a fair bit of exhaust condensation.

I would only expect exhaust condensation if I didn't drive the car enough to fully warm it up. I try to avoid that, and take the long way home, to take the best care of my car.
I'm interested in this topic though, because I'm getting some strange occurrences after going through a car wash or a day in the snow.

This vehicle collects and stores more water than any vehicle I have ever owned. I just dumps out underneath. I get a wash every day it's not actively raining or snowing and the grocery store is directly across the street. I can get a wash, go across the street and shop for 20 minutes, drive 10 minutes back home, garage it and a hour later I still have just as much water on my garage floor as when I left in my grocery store spot.
I had an Escalade before this and it would evacuate almost all the water at the grocery store and leave virtually none in my garage. I will say my GLS drains like a champ though around the windows and mirrors and lift gate. One pass with a towel is usually sufficient. My Escalade would weep for hours around all the window seals, out of the mirrors, the back glass. It was very annoying.
This discussion is so subjective though. What is a large puddle to someone could be a negligible amount to someone else. Also, so many other things like ambient temp, overall humidity, slope/grade like Wildta suggested. My first instinct is to say it's not something to be concerned about but I think a little more info is needed to say for sure IMO.
