Is It a Problem If the Car's Underbody Is Scraped?
2 Answers
When the car's underbody is scraped by an unknown object and you cannot determine if there is any damage, it is recommended to take the car to a 4S shop or repair shop for inspection. Most repair shops have underbody lifts, and once the vehicle is raised, any scratches or damage to the underbody surface can be easily identified. Methods to prevent underbody scraping and damage include: 1. Applying underbody coating: Car underbody coating can be sprayed on exposed areas such as the vehicle's underbody, wheels, fuel tank, lower body panels, and trunk. After drying quickly, it forms a firm elastic protective layer that not only prevents impacts from flying stones and gravel but also avoids erosion from moisture, acid rain, and salt on the metal parts of the underbody, preventing rust and corrosion and ensuring driving safety. 2. Installing an engine guard: The engine guard is a custom-designed protective device for various car models. Its primary purpose is to prevent mud from covering the engine and to protect the engine from damage caused by uneven road surfaces during driving.
That time I drove over a huge pothole, and the chassis made a loud bang when it hit. At the moment, I thought nothing of it, but when I got home and checked, I found a small crack in the oil pan that was leaking oil. It ended up costing me a few hundred bucks to get it fixed at the repair shop—what a hassle! Later, the mechanic told me that such impacts can easily damage components under the engine, like the fuel tank, exhaust pipe, or suspension system, which might get bent out of shape. Especially for older cars with lower ground clearance, it’s even riskier. Driving straight over it could worsen oil leaks or loosen parts, leading to a breakdown or even compromising handling safety. So, he advised that if you encounter a similar situation, it’s best to stop the car, turn off the engine, and check for obvious oil stains or damage underneath. It’s wise to get a professional inspection ASAP and not brush it off until something worse happens. Now, I drive extra cautiously over rough roads, always nervous, and make sure to check the underbody protective coating during regular maintenance.
