2006 Infiniti M35 Problems

Timing Chain Rattle and Tapping Noise

Rattling and tapping in the front of the engine on the 2006-2008 M35 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 M35 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.

2006 Infiniti M35 Recalls

Passenger Frontal Air Bag Inflator Ruptures On Deployment

The passenger frontal air bag inflator may rupture on deployment, causing metal fragments to come through the air bag and injure occupants. Dealers will replace the passenger frontal air bag inflator free of charge to resolve the concern.

Front Airbag Inflator Module

This limited regional recall is for vehicles currently registered or first sold in southern Florida, along the Gulf Coast, Puerto Rico, Hawaii, the U.S. Virgin Islands, Guam, Saipan and American Samoa. Upon deployment the passenger airbag inflator could rupture, increasing the risk of personal injury. Dealers will replace the passenger side air bag inflator to correct this concern.

Engine Stall Concern

On nearly all cars on the road today the engine idle speed is computer controlled. These vehicles are being recalled because the idle may be to low as a result of a sensor failure causing the computer to operate in the fail-safe (limp home) mode. In the limp home mode, the computer will not properly adjust for variations in the engine idle speed. As a result the engine can stall unexpectedly at idle or when coming to a stop. The sensor causing this concern is the accelerator pedal position sensor. Dealers will replace the accelerator pedal assembly and reprogram the engine control module to correct this concern.
