 I've only had my 2004 nissan sentra since February.I've had nothing but problems with it.I've already had to have a new cat converter put on.Light is on again for a gas cap code, and then last night i hit the on button for cruise....and my horn honked.It honks now whether i turn my cruise on or off.And then a couple times it didn't do it!!!Anyone else having the same problems?Especially the horn honking!!
