Recalls

1 vehicle recall from the manufacturer, plus 1 equipment/tire recall that can apply. Repairs are free. Check your VIN to see if one is still open on your car.

Engine & cooling Vehicle recall #10V517000 · 2010 · 747,480 vehicles

What's wrong: 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.

Why it matters: This could cause engine stalling increasing the risk of a crash.

The fix: Dealers will replace the ECM relay inside the ipdm assembly. This service will be performed free of charge. The safety recall began on December 6, 2010.

Why it matters: If the collar weld separates, the vehicle handling will deteriorate, possibly resulting in a vehicle crash.

The fix: Nissan will notify owners and dealers will replace any affected lower link free of charge. The safety recall began on July 12, 2010.
