I own a 2012 qx 53. At 70,000 miles I had to replace the catalytic converters, cost over $4000. I now have 154,000 miles and have been told that the catalytic converters need to be replaced again. This seems to be a common problem with this vehicle.

What 2012 Infiniti QX owners say
Most recent owner complaints, unedited.
When waiting at a stoplight for a long period the brake pedal gradually eases down and the vehicle begins to roll forward to prevent the vehicle from going forward extra pressure needs to be applied to the pedal to keep the vehicle stopped at this time the pedal is almost at the floor. Along with this the transmission started making a very loud bang when shifting gears. My car is under warranty and I took it to the dealer three times and they told me no other model has this problem this is normal .
