Just picked up my 2019 Sahara with retractable top yesterday.....love it......but I’ve noticed that water is dripping from the exhaust pipe. Just wondering if anyone else has experienced this or knows if this is a concern?

Does it stop a short while after startup? Prob no problem.

If it’s persistent while running check cylinder head gaskets on engine.

Also make sure the fluid is water and not something else like antifreeze.

It only has 82 miles and I just started to notice. I started it in the garage and saw it dripping from inside the pipe. Doesn’t appear to be coming from anywhere else. It does seem to stop once I drive a few miles.

Probably just accumulated condensation in high humidity. It should stop after it all evaporates by running the engine and heating up the exhaust system. If you have a stream flowing, you got a problem!

I’m in CT where it is cold. Does it make sense that it drips until the engine warms up?

Normal. You will see it stops when the vehicle warms up. You will see it again in the morning. NO, you will not usually see in the Summer months.

You just picked up the vehicle so it has been sitting at the dealer and this will also factor in..

I'm in NY right now and my JL does this every morning.

Thank you...makes me feel much better! It was also a build, which i’m assuming may also come into play.

Doesn't matter how long a vehicle sits. What matters is physics. See that cloud coming from every car thats running when its cold............steam caused by hot air being spewed into cold air. it condensates on the inside of the cold exhaust pipe and turns into water droplets. Once the exhaust is hot it condensates after leaving the exhaust. You still get a cloud of steam from the exhaust especially when its very cold but the dripping stops once the exhaust pipes are hot.
This is also why they tell you short trips in cold weather shorten your exhaust system life, because the pipes don't get hot enough to dry out all the condensation and your exhaust rusts sooner than those that drive longer periods before shutting off the car.

It's actually chemistry, but right on. :like:
More specifically, water and carbon dioxide are the products the combustion of hydrocarbons and oxygen. The water has to come out the exhaust pipe somehow. Usually it's water vapor, but sometimes it's liquid when the system is cold.

Wow, some real asshole replies, here. Way to welcome people to the forum.

OP, I’m glad that at least @Rhinebeck01 gave you a polite answer.

To me, no question is a stupid question.

Obviously, the OP did not know and geeeez, he/she came to a forum of fellow Jeeper's and asked a question.

I mean this is a forum and questions and answers are common place here.

Yup, a real shame that the poor guy/gal .. the OP was berated... chastised.

Ya know I can be a real prick, I can be condescending and .... but you would never catch me piling on someone that is just politely asking a simple question.

Alright... I was being a dick.

My bad.

I just would really hope that people would learn to search things up rather than ask others to answer their questions for them. Frustrates the hell out of me.

You do realize the world we live in now, right?

Exhaust systems have holes in mufflers and resonators specifically for letting water drain out of them. Some fancier mufflers use syphon tubes instead of drain holes, to avoid the sputter sound a drain hole can make. Most OEMs have requirements for condensate evacuation, it's something that's tested during development.

At least the OP didn't say it was unburnt fuel... I've seen that complaint before.
