How to solve the problem of a newly purchased car malfunctioning?

Take the car to the 4S shop and have it checked. If it's a minor issue, they will repair it for free. Contact the 4S shop to negotiate a solution. With the three-guarantee certificate and purchase invoice, the seller is responsible for replacement or return.

I just picked up my new car last week, and it's already having issues—there's a slight strange noise when starting, which makes me uneasy. As an average car owner, my first instinct was to immediately check the manual for error codes, then without hesitation, I called the dealership where I bought the car. New cars usually come with a warranty, so they handled it for free, and I drove straight over for an inspection. Never attempt to fix it yourself, as it might void the warranty. I even recorded a video of the noise to help the mechanic diagnose the issue. While new car problems are rare, it's best to address them promptly to prevent minor issues from escalating into safety hazards. Remember, authorized dealers provide quick service, and delaying repairs could increase driving risks. A friend of mine had a similar issue with his new car, and after timely repairs, everything was fine. So, I recommend taking decisive action—don’t hesitate. Try not to delay any warranty-covered issues.
