The new car has undergone strict debugging in the factory.
If that's the case, there may be something fishy between the time when the new car leaves the factory and the time you mentioned. Maybe you brought a used car, and someone bought it and returned it, and sold it to you for a new tire, or SSSS picked it up from other provinces and autonomous regions, and the car came back directly from one province. I don't know what happened during the driving!
There are not many possible reasons for the abnormal noise of the new car engine. The biggest reason is that the engine is short of water or oil and works. If so, the engine of this car will be scrapped directly. It may be an exaggeration to say scrapping, but I believe you won't accept the overhaul of the new car engine, will you?
What is the specific reason? What is the sound? It is best to consult a professional repair shop first, and start SSSS theory as soon as there is a result, so as not to be fooled!
