Scratching the car chassis can affect the vehicle's lifespan and also pose a threat to driving safety. Regular inspections are necessary. Generally, as long as the suspension system is not damaged to the point of deformation, there shouldn't be major issues. Common damages to the car chassis include: Undercarriage scraping and foreign object impacts: During road repairs, there are often large rocks or uneven surfaces. When driving on such roads, it's easy for large rocks or other protruding objects to come into close contact with the vehicle's chassis, commonly referred to as undercarriage scraping. Since undercarriage scraping is unpredictable, it can easily damage components located on the chassis, such as: cracking the catalytic converter shell, engine oil pan, or transmission housing, or deforming the suspension system. These issues can cause fatal damage to the vehicle. Corrosion: With the worsening environment, even rain has become acidic, increasing the likelihood of vehicle damage in such conditions. The chassis frequently comes into contact with sewage, grease, and other substances, whose chemical components can slowly corrode the chassis and its parts. Therefore, extra attention should be paid to chassis corrosion prevention. Besides the aforementioned risks from rainwater and oil sludge, snow-melting agents used in winter and seawater can also corrode the chassis, especially seawater.
