MY California car did great until about 44K- when the catalytic converter went out. At 52K the converter went out again, this time my car has been in the shop for over 5 weeks! Nisian said the part had to be made, then on backorder, (there were only a few hundred made of the CA sentra model). The truth is that the CA model with its 3 catalytic design just does not work- the car has run lean from the get go- what this means is that eventually the valves will permaturely fail- they are starting to go already, i pulled the spark plugs before i took to the dealler and could see detonation on the tips- not good.It seems Nissan received some form of insentive to try 3 catalytic system.
fuel economy,drivers seat is comfortable
get rid of the 3 catalytic system, increase 20HP, 16" tires should be standard, cruise should be standard,spoiler should be standard, add a few inches to the rear seat.if you are over 160lbs and taller than 5'8" you will not like the back seat.
