Condensation Dripping On Hot Exhaust???

[JWOutdoors29]

Has anyone else noticed the condensation from the A/C dripping onto the exhaust after they have been driving the truck and hearing the sizzling sound every time it drips when you get out and shut the truck off?  I've had my truck for a little over 3 months now and this has never happened until this past Friday after about a 3 hour trip.  Now it does it after every trip, even to and from work.  I had my first oil change done Thursday morning, but did drive the truck back and forth to work Thursday and Friday before the road trip and still never noticed it.  At about the 2.5 hour mark into the drive Friday night, I did hear a loud metallic sounding "pop" that sounded like a rock or something hard hit the top of the cab.  It was loud enough it startled me and made my dog jump up from a dead sleep in the back seat.  It did echo somewhat in the cab, so hard to pinpoint exactly where it came from, but it sure sounded like the top of the cab right behind the front row seats.  When I got to my destination, that's when I noticed the sizzling sound for the first time. I just assumed it was residual washer fluid dripping onto the exhaust as I had just used quite a bit attempting to clean some of the bug splatter off the windshield.  I looked the whole truck over searching for a rock chip or anything that might have been the source of the loud pop that I heard, but I could find nothing.

 

Not sure if it is all just coincidence or not, but does anyone have any ideas why the route of the condensation would suddenly change and be dripping onto the exhaust?  It's not that big of a deal I don't suppose, but kind of annoying every time you shut the truck off and it is a constant "drip... sssss... drip....ssss" for several minutes until it cools down.

Mine does it all the time for the AC. 
 

I have yet to have the roof popping noise.

Both sounds are common “complaints” on here. They all drip on the exhaust and a lot of people say the roof pops when they back out of the driveway.

I remember reading the thread about the cab popping when backing out of the driveway, and that crossed my mind if it was the same sound.  Mine just happened running down a smooth highway at 70 mph, so I wasn't sure if I was experiencing the same thing.  Hadn't read anything about the exhaust "complaint" yet, but if this is all common knowledge, thanks for the heads up and I apologize for repeating another thread.  At least my mind can rest at ease now. lol

Mine pops randomly, mostly while driving. I’ve heard it pulling out of the driveway once. It took a while for the condensation sizzle to happen on mine BUT it correlates with the weather. As it for more hot and humid outside it started doing it. Something to consider..

On evaporator condensation dripping on the exhaust manifold, if you're able to park your p/u truck in the garage that's a good thing in my mind, keeps a big puddle off your garage floor. Here in the humid south, that's a common issue and I'm constantly sweeping water off the garage floor after the wife pulls her car in after a trip out. Yes, I know I could tell her to turn the A/C off a few minutes before arriving home, but try telling a cranky old woman anything, let alone how to operate her car is an exercise in futility in the extreme.

I have the same issue on my 2019 GMC Sierra with condensation dripping on exhaust. It does it only in the morning for me once I drive to work. Had truck checked at the dealership for any damage and they found nothing.
