What causes the Nissan X-Trail to make a clicking sound and fail to start?

[MacKhloe]

The Nissan X-Trail failing to start with abnormal noises can be caused by insufficient battery power, inappropriate engine oil, or spark plug failure. The specific reasons are as follows: Insufficient battery power: Difficulty in starting the car is mostly due to a depleted battery or an expired battery lifespan. When the battery power is insufficient, the engine cranks weakly during startup, and only abnormal noises are heard. Avoid continuous ignition attempts to prevent complete battery depletion. Inappropriate engine oil: In winter, as temperatures drop, the viscosity of engine oil increases, making it harder to flow and increasing engine resistance. If starting is difficult, check whether the engine oil grade being used is incorrect. Spark plug issues: After several years of use, spark plugs are prone to problems such as carbon buildup, leakage, excessive gap, or erosion, which can cause difficulty in ignition, cold starts, or even hot starts, often requiring multiple ignition attempts. Therefore, if the vehicle has reached a certain mileage or exhibits symptoms like difficulty starting, weak acceleration, shaking, increased fuel consumption, or unexplained stalling, check the spark plug condition and replace them promptly.
