2003 Nissan Murano Problems
RepairPal has identified the most common problems with the 2003 Nissan Murano based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
A damaged or broken seat adjuster assembly on the seat bottom can cause the seat to rock back and forth and possibly squeak. It can also cause the seat to not adjust forward or backward, or up and down.
A thumping heard and felt in the floor is often caused by failing engine mounts. A failing mount allows too much movement of the engine, and will require replacement.
The screws that secure the striker (or latch) for the liftgate on the Nissan Murano commonly come out leaving the latch free to move. This movement prevents the liftgate from properly latching, and a light rattle is heard while driving over bumps.
The screws are normally attached to a metal (backing) plate inside the frame, but when they come out the backing plate falls away leaving no way to resecure the latch.
To install the latch, the backing plate must be retrieved through a bolt hole, and the screws must be replaced with a thread locking compound. There is no access to the plate except through the bolt holes.
To prevent this from occurring, the screws must be removed and reinstalled with a thread locking compound one at a time.
Rattling and tapping in the front of the engine on the 2003-2016 Nissan Murano 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 Nissan Murano 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.
A creaking or clicking heard while the vehicle is accelerating can be caused by dirt and corrosion build up between the splines of the front hubs and CV axle shafts.A creaking or clicking heard while the vehicle is accelerating can be caused by dirt and corrosion build up between the splines of the front hubs and CV axle shafts. Removing, cleaning, and applying a light coat of grease on the axle shaft splines will commonly correct this concern.
A faulty fuel damper can produce a ticking noise, which can be heard inside the cabin when the engine is idling. Replacement of the failed dampener should correct this problem.
The fuel filler door actuator relay can fail and prevent access to the gas cap.
