It is not normal for a new car to have strange noises inside; new cars generally do not produce unexplained noises. Here are a few reasons why a new car might have strange noises: 1. Improper operation by the owner: Such as inaccurate gear shifting, half-engaged gears, or pressing the accelerator with the handbrake engaged, etc., which can cause loud strange noises while driving the new car. 2. The engine oil dipstick not being tightened after use: The coolant cap not being properly closed after adding coolant can also cause strange noises in the new car. 3. Fuel system malfunction: The new car has been parked for a long time after purchase, some even in an open environment. Long-term outdoor parking can allow water molecules to seep into the fuel system, causing malfunctions.

Don't panic if you hear strange noises in your brand-new car. My third car also had minor sounds during the first two months on the road. Later, I found that nine out of ten times, it was due to coins stuck in the seat rails, the warning triangle in the trunk not being secured properly, or the window seals still being stiff and rubbing against the window frame. The occasional popping sounds from plastic parts expanding and contracting with temperature changes are completely normal. However, if you hear a continuous humming noise accompanied by steering wheel vibration, there might be an issue with the wheel hub bearing. If you hear metallic clunking sounds from the chassis when going over speed bumps, it's time to check the torque on the suspension bolts. Remember to clear all loose items from the car before testing, and if something still seems off, don't hesitate to take it back to the 4S店 for a lift inspection—new cars come with a warranty, so don't be afraid of the hassle.

As a seasoned car modification enthusiast, I can confidently say that 90% of strange noises in new cars are nothing to worry about. Just the other day, my young neighbor complained about a creaking sound when her electric car took corners. When we lifted the rear seat together, we found it was simply the portable charger rolling around because it wasn't secured properly. Some noises are inherent to manufacturing characteristics - like insufficient lubrication in panoramic sunroof tracks, or temperature differentials between leather seats and plastic trim. However, pay special attention to high-frequency buzzing, which could indicate loose high-voltage wiring harnesses. A rhythmic thumping from the rear suspension usually means the shock absorber's shipping dust cover wasn't removed. Never mask strange noises with music - pinpointing the sound source is absolutely crucial.

New car owners, don't let dealerships dismiss issues with 'it's normal during the break-in period'. Last year, two weeks after picking up my car, I noticed a squeaking sound from the right front door – turns out they forgot to install washers on the window regulator screws! For new car noises, first identify the type: plastic rattling over bumps usually indicates assembly gaps; sharp metal scraping when braking might be leftover anti-rust coating; belt whirring during cold starts typically fades in seconds. Key areas to check: glove box coins, sunglass holders, and trunk tool kits – often overlooked noise sources. Can't pinpoint it? Record the sound with your phone to show the mechanic.
