In owners' own words
In 2005, I bought a 2003 Nissan 350Z. In early november of 2011, I started having these problems.
Engine stops while driving car. Engine service light comes on. Take car to garage - engine sensors are bad - had replaced.

These service parts are intended for use on model year 2003-2006 Nissan 350Z and Infiniti G35 vehicles. The sx: K70358-01 clutch kit contains an oversized clutch disc. An oversized clutch disc could cause the vehicle to move unintentionally on the initial start-up, if the driver does not follow the installation instructions and fails to use the service brakes while the hand brake is not applied.
Certain ck motorsports combination headlights, clear corner, bumper, and side marker lights sold as replacement lamps for use on the passenger vehicles listed above. Without the amber reflectors, the vehicle will be poorly illuminated, possibly resulting in a vehicle crash without warning.
On certain passenger and sport utility vehicles, the fuel filler hose may crack and result in fuel leakage from the hose while refueling. Fuel leakage in the presence of an ignition source could result in a fire.
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. 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.
