Engine & cooling Vehicle recall #03V455000 · 2003 · 630,000 vehicles
What's wrong: On certain passenger vehicles, the circuit board for the crank position sensor or cam position sensor May have an improper solder joint due to solder deformation caused by heat stress accelerated by the existence of flux residue during the soldering process.
Why it matters: This could cause the "service engine soon" warning light to come on, create a no start condition, cause reduced engine power, or cause the engine to stop running without warning during vehicle operation, which could result in a crash.
The fix: Dealers will replace the crank position sensors. Camshaft position sensor(s), and in some cases, the variable timing control sensor(s). Vehicles involved in a previous recall campaign, 01v357, are also included in this new campaign. The replacement sensors used in that campaign are also affected.…
Fuel system Vehicle recall #12V088000 · 2012 · 8,120 vehicles
What's wrong: Due to a circuit board failure, the fuel gauge May read a fuel level higher than actually exists. As a result, the vehicle May run out of gas without notice.
Why it matters: The vehicle May stall without warning, increasing the risk of a crash.
The fix: Nissan will notify owners, and dealers will modify the circuit board free of charge. The safety recall began on April 27, 2012.
