Does car insurance cover rust damage?

Auto insurance doesn't cover rust damage because rusting is a symptom of an aging vehicle. Car insurance companies insist that accidents should be reported immediately before a vehicle rusts and causes more damage. While most companies don't provide car insurance coverage for rust damage, you should shop around and compare multiple car insurance companies with timely claims programs.

How long does it take for a car to rust after an accident?

It depends on the location of the vehicle. However, it can take four to five days for a car to start rusting around the damage.

Most auto repair and body repair shops change damaged parts, so it’s not likely that they’ll reinstall a compromised part to your vehicle.

Rust that accumulated over a few months can make repairs more difficult. In addition, components are harder to remove when they’re rusted.

Along with rust damage, car insurance companies won’t cover other car parts damaged by wear and tear (aging).

Which car insurance companies are good with claims?

Your auto insurance company won’t cover rust damage. If you’re in a car accident, you’ll need a car insurance company with a dependable claims system.

Three Things That Cause Your Car to Rust

Driving a damaged vehicle isn’t good. The rusting process might be accelerated by certain conditions. According to Dave’s Body Shop, these three things could speed up rusting:

  • Salt
  • Moisture
  • Neglect

Moisture is introduced from the weather and general car maintenance. Water can break down metal over time, leaving behind a slow build-up of rust.

Salt acts much faster than water. Although it’s helpful against black ice, it can break down components on your car.

Finally, neglecting maintenance can lead to rust on your vehicle. Pollen, dirt, and other debris can slowly rust your car. If your vehicle is damaged, rust can eat away at the compromised areas.

Why might a car insurance company cover rust damage?

Auto insurance companies may assume rust damage occurred over time. However, if you have accidental damage from a chemical that causes rapid corrosion, your company’s comprehensive car insurance may cover the damages.

Some chemicals are highly acidic. Even metals like iron and steel can corrode from strong acids.

Comprehensive insurance comes with a deductible. Getting a higher deductible will lower your overall car insurance rates, but remember that you have to pay this deductible before your car insurance company will pay out on a claim.

Car Insurance Covers Rust Damage: What’s the bottom line?

Car insurance companies won’t cover rust damage. Any damage that happens over time is your responsibility. If you get into an accident, you’ll have to make a claim.

An at-fault driver needs collision coverage to get help from their insurance company after an accident. Chemical-related accidents have to be filed under comprehensive coverage claims.
