RepairPal has identified the most common problems for 33 Infiniti models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
A brake pulsation or steering wheel vibration may be noted when braking, especially at highway speeds. Our technicians tell us that replacing the front brake backing plates, resurfacing or replacing the front brake rotors, and inspecting the front brake pads and caliper hardware and replacing as necessary will generally correct this concern.
Carbon deposits on the throttle body may cause any of the following issues: Idle speed fluctuation, incorrect idle speed, difficulty accelerating way from a stop, and or increased accelerator pedal resistance. Our technicians tell us a revised throttle body and associated parts are available to resolve this issue.
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 airbag (SRS) light may illuminate with code B1177 and/or B1182, related to the front seat belt pre-tensioners. Our technicians tell us revised front seat belt buckles are available to correct this concern.
The anti-lock brake system (ABS) and/or brake warning light may illuminate, this may or may not be associated with a brake pedal pulsation. If a trouble code C1179 is stored, reprogramming the ABS system may be necessary to correct this concern.
An abnormal noise may develop from the timing chain area, Our technicians tell us it may be necessary to replace the variable valve timing camshaft shaft sprockets to correct this concern.
Hard shifting or wrong gear selection may be corrected by reprogramming the automatic transmission ECU.
Vehicles with a 7 speed automatic transmission may experience a harsh downshift from 4th to 3rd gear on deceleration. Our technicians tell us revised control module software is available to correct this concern. On higher mileage vehicles other faults may cause transmission shifting issues. Whenever a transmission repair is performed, the control module should be checked for the latest software and updated if necessary.
The 4WD light may flash on and off intermittently with no transfer case related fault code stored in the powertrain control module (PCM). Our technicians recommend to ensure the correct Nissan/Infiniti approved fluid is present in the transfer case if this condition occurs.
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.

The fuel gauge may be slow to register, fail to read full when the gas tank is actually full, or read inaccurately. Our technicians tell us there is a redesigned fuel tank sender unit to remedy this problem.
