One problem related to ignition has been reported for the 2004 Nissan Crew. The most recently reported issues are listed below.
Bought an '04 quest with 23 miles on od in March '05. Have experienced starting problems daily for past 1 year. Always starts fine after it's been sitting with engine off for a while. Problem is when I turn engine off & try to re-start 5 minutes later. Cranks for a good minute before it finally starts. Took to dealer 2 times to get fixed; they replaced something but that didn't fix problem. They basically said they didn't know what the problem is.
