Infiniti Q45 Problems
Check Engine Light Due to Failed EVAP Purge Control Valve
Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.
Fuel Injector Problems are Common
It is not unusual for one or more of the Fuel injectors to fail. Common symptoms would be a rough idle and possible illumination of the Check Engine Light.
Lack of power on acceleration due to fuel pump issue
If the car drives well at cruise speed, but lacks power while accelerating, there may be a problem with the fuel pump.
Check Engine Light and Engine Stalling
The crankshaft angle sensor or the camshaft position sensor can fail and cause loss of engine power, an engine that cuts out, and other drivability problems. This will cause the Check Engine Light to illuminate. Certain models have been involved in a recall to replace the camshaft and crankshaft sensors.
