Noticed that truck had a lean to the passenger side. When taking left turns, truck would list and lean excessively to the passenger side. This is especially troublesome in downhill turns or under adverse weather conditions. Sought dealer help multiple times as well as Nissan consumer affairs. Dealer adjusted ride height, said these trucks had a torsion bar issue, nothing else they could o. Consumer affairs did nothing but refer me to another dealer, same result. A letter to the president of the company produced a letter back telling me to go to contact consumer affairs. Truck has also broken stabilizer nuts several times. Took vehicle to an alignment an suspension expert, said the truck ride height cannot be adjuster up to factory specs, and maintain alignment. He had to lower the vehicle to allow it to be aligned properly. It is my guess that there is a design issue or part failure. I believe Nissan knows this, and lowered the ride height themselves to allow alignment at the factory, sacrificing balance, driveability and safety. I notice most models of this truck have the same tilt to the passenger side.
