On certain vehicles, corrosion may form in the lower steering column joint and limit the movement of the joint. Limited movement of this joint may create excessive load on the lower steering column shaft and, if the vehicle continues to be driven in this condition, may lead to cracking of the shaft during low speed manoeuvres that require large steering inputs. In an extreme case, the shaft may break which would result in loss of steering control and could result in a crash. Correction: Dealers will replace the affected column shafts and joints.
Certain Hidden Hitch brand accessory trailer hitches P/N 64-3528 installed by Nissan dealers on 2002 to 2004 Frontier vehicles. With continued use, load forces may cause a side bracket of the trailer hitch to fatigue and eventually break, possibly allowing the towed unit to separate from the towing vehicle. Correction: Dealers will replace all suspect Hidden Hitch brand hitches originally installed by Nissan dealers in Canada.
On certain vehicles, the fuel pump terminal on the fuel sending unit can develop a crack. When exposed to heavy concentrations of road salt in the winter, if road salt enters the crack, the terminal strip will corrode and eventually could break due to corrosion. This will cause the fuel pump to stop operating and will result in not being able to start the engine or cause the engine to stop running without warning. Correction: Dealer will replace the fuel sender unit.
On certain four wheel drive vehicles, water may enter the rear axle housing due to inadequate sealing of the ABS sensor in the axle housing. This may result in corrosion and eventually failure of the wheel bearing. If this occurs, the wheel assembly could separate from the vehicle. Correction: Dealer will inspect the rear axle for water intrusion and replace any affected components. The ABS sensor will be resealed to prevent water intrusion.
On certain supercharged vehicles, the amount of intake air flow through the air flow meter may exceed the maximum preset diagnosis limit value which would cause the engine control system to go into the failsafe mode. Under this condition, the malfunction indicator lamp will illuminate and engine speed will not exceed 2400 rpm's regardless of throttle position. Correction: Dealer will reprogram the electronic control module (ECM).
