Nissan is committed to providing the highest levels of product quality and customer satisfaction. We know that towing a trailer may have been an important consideration in the customer's purchase decision. In new Titan, Armada, Frontier, Pathfinder, and Xterra vehicles, Nissan recently introduced enhanced electronic circuitry which may help further protect a vehicle from damage or fire caused by a short circuit in the electrical system of a towed trailer due to problems with the trailer’s wiring or mis-installation of trailer lighting or electrical accessories. Nissan is making this production enhancement available to owners of previously purchased vehicles so that they will have the same protection should they ever tow a trailer with a defective electrical system.

My father in law owns a mech. shop and thinks the brake situtaion is realated to the Body control unit. i also just had the problem when i push the gas pedal all the way down that i lose alot of power, which i do know that is a tsb on the fuel pump. but do you guys think that the dealership will replace the bcu? i am out of warrently b/c i drive all day in my truck.

what do you guys think?
