Known Problems

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. 

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. 

The Check Engine Light may illuminate due to an EVAP system charcoal canister purge control valve fault. Our technicians tell us that if the valve requires replacement, a revised part is available which should be installed.

A stalling or low engine idle speed condition may develop. Our technicians tell us a software upgrade for the powertrain control module (PCM) is available to address this problem.

Our technicians tell us that if a door mirror becomes inoperative due to an actuator fault, the faulty actuator may be replaced, negating the need to replace the entire door mirror.

All wheel drive vehicles may develop a groaning type noise from the steering rack when centering the steering wheel after turning right at slow speeds, most noticeable when driven from a cold start. Our technicians tell us a revised steering rack is available to correct this concern.

An abnormal noise may be noted from the timing chain area, along with illumination of the Check Engine Light with code P0011, P0014, P0024, P1110, or P1135. Our technicians recommend to check the engine oil level and pressure prior to changing the variable camshaft timing sprocket.

The traction control/anti-lock brake system (ABS)/Slip warning light may illuminate with code C1142 stored, Our technicians suggest that if the brake light switch and brake pedal are operating correctly, the ABS control module and actuator may require replacement.
