2000 Infiniti I30 Engine cooling Problems

“2000 infinity i30t : from forums on internet, it seems that there is a common problem with the exhaust system on this model. There is a code p0420 that indicates a problem with the bank 1 catalytic converter. Infinity states that because the catalytic converter is enclosed in a front tube assembly , it is not covered under the 80,000 mile warranty. I have replaced the rear cat, o2 sensors, mass air sensor and engine coils. The p0420 code was also worked on before we owned the car at 29,000 miles.”

“Vehicle: 2000 Infiniti i30t has a recurring engine code p0420 since 74,000 miles. Found out recently there is a service bulletin for this problem on the internet. Reference #itb00-054a. I never received any notice from Infiniti corp. About this problem since the service bulletin that occurred on june 7, 2004. It is wrong for Infiniti not to notify their customers about this problem. There is no drivability problem, but I will not pass california smog test if the engine come on during this time. Infiniti corporation should fix this problem without charging any labor or parts. …”

“2000 Infiniti I30 service engine soon came on. Dealer diagnosed and concluded that the ignition coils went bad and need to replace all 6 of them. The car had only 31753 miles on it. Considering the low mileage, it is too early for the coils to go bad. Dealer said it is not covered under warranty (federal emissions warranty was still valid) and had to pay 1000 dollars for the job.”
