Does gravel hitting the undercarriage affect the car?

[DiCollin]

Gravel hitting the undercarriage does affect the car. Here are the specific details: 1. Minor scratches: The impact is minimal. There is a layer of metal sheet under the car's undercarriage, which can be repaired and improved during the next maintenance or repair. 2. Severe impacts: It is necessary to stop and inspect the car, mainly checking whether the oil pan is cracked, whether the tie rod is deformed, and whether the brake lines are broken or damaged, as these directly affect driving safety. 3. Consequences: For small cars, undercarriage scrapes by stones often result in oil pan damage leading to oil leaks, while other issues are relatively less common. However, for your own safety, it is advisable to have it checked at the nearest repair shop.
