2003 Nissan Murano Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2003 Nissan Murano

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.

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 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.

Nissan is recalling 2003–2007 Murano models because the intake air ducts may separate from the resonator with engine movement. This may cause the engine to stall, increasing the risk of a crash. Dealers will inspect and repair/replace the components free of charge.

In certain types of frontal crashes, the belt portion of the rear outboard seat belt may contact the rear seat back hinge. The belt can be cut by the sharp edge of the hinge. If the belt were to completely separate, it can increase the risk of injury to the seat occupant. Dealers will install protectors over the affected belt portion of the rear belts.

Road debris, when run over by the front tires, can be projected in the direction of the fuel tank. If struck, the fuel tank could be damaged, possibly resulting in a fuel leak. A fuel leak always increases the risk of a fire. Dealers will install a protector in front of the fuel tank to correct this concern.

Murano gear transmission systems is particularly problematic.

Now have 103,000 miles. Third alternator, gave up on replacing fuses for mirror, cig lighter and headlight adjustment. Electrics remind me of my TR6. Zenon headlights are awesome but irresistable to dirtbag thieves. Seat bracket on drivers seat replaced twice- I'm an atheletic 200 pounder but have never had a seat bracket break- very cheap metal but pricey. Gas door, Sunroof (closing) constant ...
