“I purchased my 2011 Infiniti qx56in january of 2015 with 36,6036 miles on it. I take excellent care of my vehicle mechanically and cleanliness. On august 17th, 2019 my back a frame and other rear suspension broke due to corrosion and the metal split apart. My under carriage also looks like and old car. My car is washed twice a week even in the winter to remove the salt. This is not covered under any of my warranties. It is going to cost me $5,200.00 to make this repair. …”

“When driving 40-70 MPH and hitting any road irregularities (offsets in pavement at bridges, old to new pavement, man hole covers, road patches) the vehicle back end skips sideways with a loss of control. The vehicle will start to head into the next lane and needs to be steered in the opposite direction to correct it. We do not feel safe driving it. Others in the car have said they have never experienced anything like it. Dealership is telling us this is normal. Vehicle is under warranty and we can't get resolution to this.”

“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. On numerous occasions the vehicle drifts out of the lane. No accidents have ever occurred but at least three near misses on interstate driving have occurred. At highway speeds it is scary and quite dangerous.”

“The rear controls arms and cradle mount were riddled with severe fissures, causing car to sway dramatically. The level of component failure posed a severe safety risk to me. My mechanic was shocked by the amount of failure to these major rear suspension components. I have included photos and receipts for repairs.”
