Some Nissan Murano owners report experiencing starting issues even after replacing the battery, which may be attributed to several potential causes. These include problems with the key fob, a faulty starter motor, or worn-out spark plugs. Additionally, some owners find that a dead or failing battery can lead to symptoms such as dimming lights or slow cranking. Other common culprits for a non-starting Murano may include a bad alternator, clogged fuel filter, broken starter, blown fuse, empty gas tank, immobilizer error, or faults in the electrical system. It is crucial for owners to investigate these underlying causes to effectively diagnose and resolve the issue.

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.
