When owners reported it
Related recalls (2)
Engine and engine cooling
Problem: On certain passenger vehicles equipped with a 2.5l engine, the crankshaft position sensor can overheat causing a brief interruption in the signal output from the sensor.
Risk: If the interruption in the signal from the crankshaft position sensor is so brief that the electronic control module (ecm) logic does not have time to diagnose the condition, the engine may stop running without warning while the vehicle is driven at a low speed increasing the risk of a crash.
Fix: Dealers will reprogram the ecm free of charge. Certain my 2006 altimas which have been previously remedied under recall campaign 06v223 (nissan r0606) are not included in this recall since the reprogramming for 06v223 also included this reprogramming. The recall began on december 31, 2007. Owners may contact nissan at 1-800-647-7261.
Engine and engine cooling
Problem: Certain passenger vehicles equipped with 2.5l engines may experience excessive engine oil consumption as a result of improper performance of the piston rings.
Risk: If the oil is not maintained at least at the minimum level, engine damage can occur and in extreme cases result in an engine fire.
Fix: Dealers will reprogram the electronic control module (ecm or engine computer). Your vehicle will also be inspected to determine if it has been consuming engine oil at a higher than normal rate. In a small percentage of vehicles, engine replacement will be needed. On june 9, 2006, nissan notified owners of the possibility of excessive oil consumption and the importance of maintaining the oil at a proper level. Follow-up letter to owners advising them of the status of the recall was sent during august 2006. Followup letter to owners was sent on november 15, 2006. Owners may contact nissan at 1-800-647-7261.
