 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.
