Recalls
4 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Electrical Vehicle recall #00V410000 · 2000 · 9,200 vehicles
What's wrong: These vehicles May have an ignition lock assembly with improperly seated key cylinder cap connector pins. Vibration can cause the connecting pins to loosen and/or fall out allowing the key cylinder cap to disengage from the key cylinder.
Why it matters: If this occurs, the steering wheel lock rod can move, which could lock the steering wheel, increasing the risk of a crash.
The fix: Dealers will inspect the ignition lock assembly and assemblies with loose or missing end cap connector pins will be replaced. A ring clip will be installed on all others to prevent loosening of the pins.
Body & structure Vehicle recall #01V282000 · 2001 · 31,000 vehicles
What's wrong: Some of the brackets used to attach the two gas struts to the rear door (hatch) May have been improperly made. At high ambient temperatures, the increase in gas pressure in the strut(s) could cause one or both brackets to bend, resulting in the struts detaching from the bracket(s) when opening or closing the rear door.
Why it matters: If both struts detach from the brackets, the door will rapidly fall down, possibly striking someone and causing serious injury.
The fix: Dealers will replace the strut brackets. Owner notification began September 24, 2001.
Fuel system Vehicle recall #07V435000 · 2007 · 372,250 vehicles
What's wrong: On certain vehicles originally sold in or currently registered in the states of connecticut, delaware, iowa, illinois, indiana, kentucky, massachusetts, maine, maryland, michigan, minnesota, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, tennessee, vermont, virginia, west virginia , wisconsin and the district of columbia, during the coating process of the fuel filler tube assembly, an…
Why it matters: This May result in surface rust but not perforation of the tube. However, in those areas of the country which use heavy concentrations of road salt in the winter, if a mixture of snow/water and salt makes contact with the bare metal, corrosion May occur to a degree which results in perforation of…
The fix: Dealers will replace the fuel filler tube assembly with a new one with an improved coating process. The recall began on November 26, 2007.
Suspension, Steering Vehicle recall #11V244000 · 2011 · 195,991 vehicles
What's wrong: C., west virginia and wisconsin. In areas of the country in which heavy concentrations of road salt are used, a mixture of snow/water and salt May enter an assembly location hole in the upper strut housing, causing water to collect at the mating surface of the strut housing panel and the inner hood ledge assembly. Over time, this snow/water and salt intrusion May result in corrosion of the strut tower housing in…
Why it matters: The strut housing May crack and pull away from the inner hood ledge assembly. This May lead to grinding noises, increased steering effort, and possibly the steering column to break, resulting in the loss of steering control, which could result in a crash.
The fix: Nissan will inspect the strut housing and repair the vehicles as necessary, free of charge. An interim notification letter was sent out in May 2011. The second notice was mailed on July 25, 2011.
