Undercarriage car damage includes any damage that impacts the undercarriage of your car—or the parts of your car that are directly exposed to the road—including your exhaust system, suspension, and gas tank.

When inspecting your car for damage, most people think about visible damage to the body of their car and internal engine damage. If you nick your door on a post, accidentally back into a barrier, or see smoke coming from your hood, you immediately know where you should check for damage.

But what about the last time you hit a speed bump too quickly or drove down a road filled with potholes? While you can’t easily see damage underneath your car, undercarriage damage is important to look out for to keep your car in optimal condition.

It’s not always easy to spot undercarriage car damage, so Jerry, the car insurance comparison and trustworthy super app, has created a complete guide on everything you need to know. We’ll go over what your car’s undercarriage is, how it can get damaged, and the undercarriage damage signs you should look out for.

What is a car’s undercarriage?

The undercarriage of a car describes the system of parts underneath a car’s main cabin that is directly exposed to the road. Some larger parts that live in a car’s undercarriage are the exhaust system, suspension, and gas tank.

A car’s undercarriage is meant to protect the bottom mechanics of a car, so these parts are built tough and designed to withstand continuous exposure to the road and outdoor elements. That said, it’s not unbreakable, which is why it’s important to keep an eye out for undercarriage damage.

What does undercarriage damage mean?

Undercarriage damage describes any kind of harm done to the underside of a car. The undercarriage is always exposed to the road, so it experiences constant wear and tear from debris, road conditions, and the weather.

What causes undercarriage damage

Your car’s undercarriage can become damaged in several ways. Here are the most popular causes of undercarriage car damage:

  • Mud: If you regularly take your car off-roading, travel on dirt roads, or live in a rainy place, the mud that gets kicked up into your undercarriage from your wheels can cause damage. Mud holds moisture, so caked-on mud can cause parts of your undercarriage to rust.
  • Salt: Salt undercarriage damage is most popular in cold-weather areas, where road salt is used to melt ice to keep driving conditions safe. Continuous exposure to salt can cause parts of your undercarriage to corrode, leaving important parts of your car vulnerable to further damage.
  • Potholes: Hitting a pothole at a high speed can often be enough to seriously damage the undercarriage of your car. The impact can cause your car to hit asphalt, gravel, or dirt. This impact may lead to fluid leaks, exhaust damage, suspension damage, or cracks. Many times this type of damage is called bottoming out.

How to identify undercarriage damage

While it’s tough (and sometimes dangerous) to get underneath your car and look for visible damage, there are signs to look out for that may indicate your car’s undercarriage is damaged. Here are the most common signs of a damaged car undercarriage:

  • Leaking fluid: If you notice pools of fluid underneath your car or even inside your car’s wheel wells, this could be a sign that part of your undercarriage is damaged.
  • Strong oil smell: If you see or smell engine oil in or underneath your car, this could signify that part of your car’s undercarriage, such as an oil pan, is cracked and needs repairing.
  • Steering problems: If you notice your car veering to the left or right while driving or find that your steering wheel is less responsive to turning, this could be a sign that part of your undercarriage, such as your car’s control arm or steering knuckle, is damaged and needs to be looked at.
  • Visible scrapes or hanging parts: If you see scrapes around the base of your car or notice anything hanging down while parked, you’ve likely hit something on the road that’s caused damage to the undercarriage of your car.

If you suspect that your car has undercarriage damage, you should bring it to a repair shop as soon as possible. Keeping up with undercarriage maintenance is just as important as regular car maintenance.
