“I own a QX56 and I brought it to the dealership because the check engine light was on I was told both of my catalytic converters have gone out. I purchased the extended warranty but the say it is not covered under my warranty. Doing a lil research on it I see plenty of people are having the same problem. This part should be recalled or at least covered under warranty. Love my truck but definitely not happy right now. Infiniti needs to do something about this situation.”
