I posted the qurestion about seeing water coming out the underneath the car few days ago. thanks for all advise. I took a close look at the problem. I noticed that the water are dripping out from one of the muffler joint. Water came out after I moved the car after it parked for 2 days over the weekend. I saw the water coming out after I stopped the car before. I am worrying about why water coming out from the muffler pipe? Is it indicated a serious problem instead of just muffler leaking? Please advise. The car is a 2004 Jeep Liberty. Thanks for your help.

Water vapor is one of the gases produced by the engine. So that is normal. The way to avoid it is always run the car for at least half an hour that way the muffler gets hot enough that no water stays in it.

Water and water vapor normally collects in an exhaust system. Basic physics tells us that hot air expands, and as the air cools it becomes more dense and water vapor forms. Try taking a used plastic milk jug, filling it with hot water and emptying it, then cap it. As it cools, the jug will colapse. If you live in a region that is colder and wetter during the winter, you will notice more vapor condensing in your exhaust tubing. This is also the reason you see tractors and some VW Bugs that have "stinger" exhaust pipes that stick up from the engine having a flapper exhaust cap on the end of the pipe. This reduces cold air from going down the pipe and condensing on and around the exhaust valve, potentially damagine the valves. Don't worry about your vehicle unless you notice a loss of engine coolant over time. Happy motoring!

If what you see is straight water, you have no problem. If it is coolant (colored greenish or redish or blueish) there may be a problem with a head gasket or a cracked head.
The normal process of burning gasoline results in CO2, Nitrogen, and Water vapor. If it runs for a few minutes and gets shut off, the water vapor will condense in the exhaust, and then drip when it can find a leak.
Good Luck and Merry Christmas

if as you say its from the muffler this tells me that the exaust system has not heated up to full temp leaving condensation, a by product of fuel ignition, behind. it will build up in the differant parts of the system. this is why some cars change mufflers more often as they rust from the inside out. people with a long commute to work change parts less often

If its just water, no need for worry. Condensation or rain maybe.
When weird fluids, lime green(anti freeze), or other strange oily or weird liquids then maybe get it checked, plain water, don't worry
