2005 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl 5M)
Time Reveals Reliability
 I've previously owned 4 Nissans.  Had balky starting problem/engine miss caused by 2 oil clogged crankshaft and camshaft sensors. Recall reprograms ECM to address safety concerns (of sudden power loss) rather than starting /missing problems. I replaced sensors myself to avoid $300 to dealer. Odometer 64K. Must now watch oil consumption for signs of disintegrating catalytic converters that cause $6000 destruction of engine.  2.5 engine also susceptible to blown head gasket/leaking coolant into cylinders.  Nissan (dealers/Corporate) blame irrelevant oil maintenance to avoid reimbursing owners. Many, many complaints on Edmunds website. I'll be looking elsewhere for another brand.
