Some INFINITI QX80 owners report experiencing clicking and fluttering sounds when attempting to start their vehicle, which may indicate issues related to the battery or the starter motor. A weak battery is often cited as a common cause, leading to rapid clicking noises if it lacks sufficient charge to power the starter motor. Additionally, some owners have reported that a malfunctioning starter motor can produce similar sounds, preventing the engine from starting even with a healthy battery. Issues with the starter solenoid may also contribute to the problem, as a failing solenoid can result in clicking noises without fully engaging the starter motor. If these symptoms persist, it is advisable for owners to have the electrical system checked by a professional to identify any underlying issues. In cases where the battery is identified as the culprit, replacing it with a properly charged unit can often resolve the starting problems. For ongoing issues, consulting a qualified mechanic is recommended to diagnose and address the specific cause of the starting difficulties.
