2004 Infiniti G35 Problems

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.

Timing Chain Rattle and Tapping Noise

Rattling and tapping in the front of the engine on the 2003-2007 G35 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. 

Erratic or High Idle After Cleaning Throttle Body

The throttle body for the Infiniti G35 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.

Love my 11 year old G35 Sedan AWD! I hate to be finally trading it in after 115K miles. I've had so few issues with the vehicle but the years start to accumulate small items you can't avoid. After 11 years it is still brutally quick and agile. The AWD has always been awesome. It used to be my snow skiing car since it handled snowy mountain passes so well as long as the snow wasn't too deep ...
I started having trouble with my car a couple months ago. Before that well pleased. I was driving in town and all of sudden this loud noise. I thought my car was quitting. I took it in, they said the muffler has come apart from the inside and is causing a rattling noise. The dash vibrates going down the road. I didn't buy the idea. I took it back, had the pad and rotors changed and put n...
