2001 Nissan Maxima : in December 2004 service engine light came on and I pulled code p0420. Vehicle was under 80,000 emissions warranty. Dealer "reprogrammed the ecm". Feb 2007 at 81,800 miles, but within the 96 month warranty, same code appears, however now dealer says that O2 sensor and catalytic converter are bad. Dealer says O2 sensor damaged catalytic converter, yet no code appeared for the O2 sensor, and vehicle was only driven less than 2 days with light on. In process of dealing with Nissan north America for replacement. Also, vehicle was new out of alignment, and alignment was never perfect.
Service engine light stays on approximately 70% of the time. Purchased car in Nov 2000.
