Why is the X-Trail's idle noise so loud?

The reasons for the loud idle noise of the X-Trail are: 1. Aging or loosening of engine mounts; 2. Improper use of engine oil; 3. Engine misfire; 4. Improper gear clearance adjustment. The X-Trail is a compact 5-door 5-seat SUV with body dimensions of: length 4675mm, width 1820mm, height 1722mm, wheelbase 2706mm, and fuel tank capacity of 65 liters. The X-Trail is equipped with a 2.0L engine and CVT continuously variable transmission, with a maximum power of 111 kW and maximum torque of 194 Nm. It features front-wheel drive, MacPherson strut front suspension, and multi-link independent rear suspension.
I've been driving for several years and have encountered the issue of loud idling noise with the X-Trail multiple times. It could be due to aging or loosened engine mounts, causing the entire engine's vibrations to transmit into the cabin, resulting in a humming sound. Additionally, if there's a crack or corrosion in the exhaust system, exhaust leaks can produce a popping noise, especially noticeable at idle. The fan running too frequently or worn fan bearings can also create a continuous whining sound, which is quite annoying. Loud idling noise not only affects the driving mood but may also lead to a slight increase in fuel consumption. It's advisable to pay more attention to inspecting these components during regular vehicle maintenance and replace the mounts or exhaust parts promptly if issues are found, effectively reducing the noise impact on comfort.
As a homemaker, I often drive the X-Trail to pick up and drop off my kids, and the loud idle noise makes them irritable. I've found that the causes are mostly related to a loose exhaust pipe or excessive fan operation causing additional vibrations. When the air conditioning is on, the compressor adds to the roar. Loud noise is not only uncomfortable but also affects driving safety because it makes it hard to hear road conditions. Try checking the engine mounts; if they're worn out, replacing them can reduce the noise. The X-Trail is a Japanese car with a reasonably good design, but any car will age, so maintaining the exhaust and cooling systems is important.
