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.
On certain vehicles the Intelligent Power Distribution Module (IPDM) assembly contains an Engine Control Module (ECM) relay that has a diode for electrical current noise reduction. The ECM relay may allow silicon vapor to form and over time the silicon evaporates from the diode molding which causes silicon oxide to develop on the ECM relay contact due to arcing. In certain instances, this oxidation could cause engine performance issues (hesitation, rough engine idle, slow start/no-start condition), and engine stalling at low engine speeds which may result in a crash. Correction: Dealers will replace the Engine Control Module (ECM) relay.
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.
