general problems of the 2011 Infiniti QX56

Catalytic converter, a/f sensor failed on the interstate when I was driving with kids in the car. Took vehicle to the nearest dealer only to be told that this is a known problem with these vehicles and it was going to cost me $3,100 to repair.

A check engine light (cel) appeared on my 2011 Infiniti Qx56 at 89k miles. Error is a bad catalytic converter on bank 1. The exact message on odb2 reader p0420 catalyst system efficiency below threshold bank 1. This issue just happened after I just replaced a bad O2 sensor after a cel.

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.

While driving "service engine soon" light came on, noticed power loss. Diagnosed with bad catalytic converter at 85k miles.

Tl- the contact owns a 2011 Infiniti Qx56. The contact stated that an abnormal noise occurred when the vehicle being fueled. The check engine warning light illuminated. The vehicle was not taken to a dealer or an independent mechanic for a diagnostic testing of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 126,557. Aw.

Timing chain failure and also catalytic converters failed.

Check engine light on, both catalytic converters needed replacing.

I have a failed fuel rail pressure sensor which is part of a voluntary safety recall that was done in 2012. I called the manufacturer to inform them about my fuel sensor they told me that my car isn't part of the recall because their engineers determined that it wasn't part of the recall! I'm not sure how they determined that out of all cars produced that year. Now I'm stuck with a car I can't drive unless I take it to the dealership and spend money to get it fixed. My only hope now is that someone from NHTSA can help me out and get them to fix their defective part! thanks.

Catalytic converter issues causing the check engine light to come on.

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 bring my kids to school this morning, I noticed a strong smell of gasoline, so I checked underneath and saw gas steadily streaming from the car and forming a puddles,I am having the car towed to dealer's garage for repair later this week. The car has never been in an accident. The fuel line leak may be related Infiniti's recall: NHTSA 14v-683.

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. The fuel line leak may be related Infiniti's recall: NHTSA 14v-683.

Service engine light on. Both catalytic converters needed replacing at 82,000.
