What owners wrote

Fuel line failure: a fuel line fitting/clamp on back side of engine (drivers side) is streaming fuel at a rate of approximately 1/2 cup per minute. While starting my car this morning, I noticed a strong smell of gasoline, so I checked underneath and saw gas steadily streaming from the car and forming a 2 foot diameter puddle. I am having the car towed to dealer's garage for repair later this week. The car has approximately 25000 miles and has never been in an accident.

Less than a year after I got the timing debacle fixed, I get a "check engine light" on 2011 qx56. According to my warranty approved mechanic both cats were gone and were not covered. This complaint is the beginning of my goal of getting assurant or infiniti to own this problem since the combined ca and fed cat warranty is 150k miles. My warranty should cover.
