2004 Nissan Quest 3.5 SE 4dr Minivan (3.5L 6cyl 5A)
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.
Great performance and ride for a van. Very comfortable for traveling long distances. Nice style inside and out, sky-view roof was very nice feature. Kids all loved it.
Replace timing chains with something that is less costly to maintain or build better quality with components that support the chains. They need better quality control for the long term owner. Its fine if you trade in every 2 or 3 years under warranty.
