2002 Infiniti I35 ProblemsCheck 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.

Rattling and tapping in the front of the engine on the 2002-2004 Infiniti I35 is very evident, especially on cold starts. This rattling noise should not be taken lightly as it warns of upcoming timing chain failure.
The cause of the noise is faulty timing chain guide rails and timing chain tensioners that wear out well ahead of schedule. These components are there to keep the timing chain tight and properly positioned. When these parts fail, the timing chain becomes loose, and pieces of the timing chain guides break off, falling into the oil pan.
To remedy the situation, Nissan/Infiniti has made revised guides and tensioners, but replacement can be very costly.
Proper oil change intervals and oil type may help slow or prevent the situation.
The throttle body for the Infiniti I35 is known for carbon buildup, and requires regular, light cleaning to maintain peak performance. After cleaning the throttle body, many owners notice a very high idle, erratic (bouncing) idle, and unpredictable power surging.
The cause is normal ECU adaptation: When the throttle body builds up carbon, the rate of airflow is slightly decreased. The vehicles computer reads this decrease in air volume, and adjusts the throttle body settings to maintain the proper engine idle speed. When the carbon is cleaned out, the ECU now registers too much air, and cannot adjust back to the original settings. While it is trying to change settings, the idle will bounce from low to high, and the car will surge forward at times.
It has been recommended to simply wipe inside the throttle body every 12,000 miles, and never to touch the flap inside. Also, the cleaning procedure may be best left to a qualified technician.
The solution can be as simple as disconnecting the battery for at least an hour, having the dealer reset the computer, or, in extreme cases, replace the throttle bodies.

2002 Infiniti I35 RecallsFront Airbag Inflator Module
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Honda dealers will replace the affected airbag inflator modules to correct this concern.
Airbags use a chemical reaction contained in an inflator module to create the pressure necessary to inflate the bags when deployment is required. These vehicles are being recalled because the front passenger airbag inflator may produce excessive internal pressure when deployed. As a result, the inflator module could rupture, causing metal fragments to strike vehicle occupants. Dealers will inspect and replace any defective passenger front airbag inflator modules found.
The circuit board for the crank position sensor and cam position sensor may have improper solder joints. This could cause the Service Engine Soon lamp to come on, the engine may not start, you could experience reduced power, or the engine may stall without warning, which could result in a crash. Dealers will replace the the crank position sensor, cam position sensors, and in some cases, the variable timing control sensors. The recall began on December 22, 2003. The Nissan recall number is R2022 and the Infiniti recall number is R3021.
