2003 Nissan Altima Sedan 3.5 SE 4dr Sedan (3.5L 6cyl 4A)
NEVER buy a NISSAN!!
 Worst, most expensive car to maintain I have ever owned.  If the gas pedal sticks and then doesn't randomly, I'm afraid to drive this car. We have replaced so many parts I could not possibly list them all here. The dealer is NO help, they diagnose, take your cash and you're back in 2 weeks. This model should have been recalled!!! Car has been maintained since we got it with 32000. Looks nice, under the hood it is a real nightmare. Only foreign car we own, will NEVER get another Nissan. They should care about their customers before their cars kill us!!
