Why would a 2000 Nissan Altima have hesitation?

Nissan is a piece of CRAP!! I've had soo many problems with my 2006 Altima 2.5s! O2 Sensor,crankshaft,oil and radiator fluid evaporating(no leaks)! Car hestiation,bucking,speed goes down just a mess! Nissan knows that their 2000-2006 was a recall,but the insist on selling and telling people they have good cars or that people are taking care of the car! A friend of mine also has a nissan altima her car stopped on the intersection with her 2yr old in the car.She almost died that day,cars had to jumped over in order to NOT hit them! She has been to Nissan several time abt this problem! I tell everyone DO NOT buy a nissan altima or any other car from the Dishonest Company! GoodLuck hun...I wish I could sue their A!
