I recently bought my Nissan X-Trail and noticed that it makes a strange knocking sound every time I start it up. It seems to go away after a few minutes, but I'm worried it might be a sign of a bigger issue. What could be causing this and should I take it to a mechanic?
ReplyIt's normal for some cars, including Nissan X-Trails, to make a knocking sound when starting up. This usually happens when your engine is cold and the oil is thicker, causing the pistons to move more slowly. As the engine warms up, the knocking sound should go away. However, if the sound persists or gets louder, it's best to have it checked by a mechanic.
