Is it harmful if a sedan's chassis is scraped?

[VanLaura]

Whether scraping a sedan's chassis is harmful depends on the following actual situations for differentiated analysis: 1. If the suspension system is not damaged to cause deformation, and there is no oil leakage, then there is no impact. 2. If the control arm is severely scraped and deformed, the car's four-wheel alignment parameters will be disrupted, causing the vehicle to deviate from its direction or even produce severe friction noises. 3. If the reinforcement components of the car chassis are scraped, causing the coating to be scratched and exposing the metal, it should be treated promptly to avoid chassis corrosion. Below are methods to prevent scraping the sedan's chassis: 1. Install an engine guard plate. The guard plate can reduce damage to the engine from scraping, but it may affect engine heat dissipation and could hinder engine sinking during a collision, posing a safety hazard. 2. Apply chassis armor coating.
