Timing chain started rattling @ 125,000 miles.. However, my VIN shows no recall for my car. Cats went bad, had to be replaced and now need to be replaced again. Yet no recall on my car. The battery constantly goes dead in the car.

A subframe is a key structural component of every car. As such, it stands to reason that it should last as long as the car itself.

Our 2011 Infiniti QX56 cannot be properly controlled at speed when any rough pavement, pot hole, bridge connection joints, or similar is ran over. The vehicle shakes violently with little if any control by the driver.
