Hello, I have a 2008 Titan. It has 11,000 miles on it. Ever since I have bought it, it has dripped water out of the tail pipe upon starting it up. It will drip for about 3-5 minutes and then stop. I have heard of condensation, but this seems like a lot. It leaves a wet circle on the ground. The truck runs perfect and when done driving no longer drips. I work in town and this truck does not get out of town and on the highway that much. Maybe once a week. Any ideas, is this normal? Thanks in advance!
