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.
Altima is a fun car to drive. Responsive and peppy.
Voluntary recall to inspect/replace pre-Catalytic converter to prevent breakup of converter contents from clogging 2nd cat and blowing material back into engine causing its destruction. Federal emission warranty covers up to 80,000 miles on cat converters. NHTSA should require mandatory recall.
