Unhappy ex-owner 
2004 Nissan Quest Minivan 3.5 SE 4dr Minivan (3.5L 6cyl 5A)
Disappointing Reliability  
 Very disappointing reliability, just over 60,000/5 yer drive train warranty, required new front wheel bearings, the one month later a new timing chain was needed. Timing chain is supposed to last life of engine. Is a $2,500 service job. Nissan would not cover, decided to trade in. Be very wary if purchasing a used 2004 Quest van if the timing chains have not been replaced yet. Nissan is aware of problem, issues a tech bulletin 1 year ago, but no recall. If buying a newer year, make sure you bring it in for service if engine ever makes a whining sound before warranty is up. I had planned on keeping it more than 5 years and 60,700 miles but could not see spending an additional $2,500 now.
