In reply to Xavier.

I haven’t had water in my cab yet but I hear it sloshing around when I am driving and it is beginning to smell like mold when the AC is on. I also found the hole in the insulation under the truck. The insulation was moist but I could not find a hose and I didn’t want to tear off the insulation to look for a hose. There is a hose in the drivers side area that looks like it could be it. It’s to the right of the accelerator pedal. Pull back the carpet to get behind the center console and you will see it. I tried blowing it out but got no water.
I called the dealership and they could not tell me where it is. I’m getting very frustrated with this.

That is the same with mine. The customer care person told me it was my fault that I had paint chips, paint peeling and water leaks. “Sorry, but some trucks just are that way” is not what you tell your customers.
After this truck, which should be my favorite, I will never,ever by a GM product again.

Where can i find tha A/C drain on a Chev Colorado 2017? I find a hole in the insulation on the left side of the truck but no hose.

My 2015 GMC Canyon is leaking and the first time I noticed it had 1 inch of water on the driver side front cab. I have brought it to the dealership to get fixed and they told me it was the emergency brake boot and replaced it. the next time it rained it leaked again and it has been back in the shop two more times with the same outcome they don’t know where it is leaking from. I got frustrated and called the customer care number listed in the owners manual and it was a complete waste of time she was no help at all. I have been loyal to GM and have bought around 15 new GM cars but this one was my last one. They keep saying sorry and I know it is frustrating but not offering me anything! all I want is for my truck to be fixed that is all!!!!!!!!!!!
