Is an Oil Leak Covered Under Warranty?

What causes an oil leak?

Oil leaks can occur for many reasons, and pinpointing the cause is crucial for determining if the issue is covered under a warranty. Some of the most common causes include:

• Worn or damaged gaskets and seals: Over time, these components can degrade due to heat, pressure and age, leading to leaks.
• Oil pan damage: Striking road debris or driving over curbs can puncture or crack the oil pan.
• Loose or worn drain plugs: During oil changes, the drain plug might not be properly tightened or could have a worn washer, leading to leaks.
• Valve cover gasket failure: These gaskets seal the top of the engine and are known to leak as they age.
• Crankshaft or camshaft seal wear: These rotating engine components have seals that can wear out and leak oil.
• Improper oil filter installation: An incorrectly installed or poor-quality oil filter can also be a source of leaks.

Oil leak warranty coverage

An oil leak may be covered under a factory warranty or an extended warranty depending on the reason for the leak, how serious the issue is and the level of coverage you have.

Factory warranties

All new cars sold in the U.S. come with a factory warranty, also called a manufacturer’s warranty, which protects the owner against defects for a period of time. Factory warranties include both bumper-to-bumper coverage and powertrain coverage.

Bumper-to-bumper warranties cover most components and typically last for at least three years or 36,000 miles. Powertrain warranties cover under-the-hood components, including your engine, transmission and other parts, and they typically last at least five years or 60,000 miles.

Many factory warranties define oil-related components as internally lubricated engine components, and they’re generally covered under a powertrain warranty. If you have an oil leak due to a factory defect while your car is under warranty, it should be covered.

Extended warranties

Extended warranties typically provide some type of coverage for oil leaks. They also typically offer more warranty plans than auto manufacturers, so you may be able to customize coverage according to what you’re looking for.

When is an oil leak not covered by a warranty?

Whether or not an oil leak will be covered under an auto warranty depends on the type of coverage you have, the cause of the leak, how long it has been going on, how serious the issue is and any related failures.

For instance, if the failure is a straightforward gasket issue, your warranty might not cover the repairs because gaskets are considered wear-and-tear items designed to degrade over time. Some warranties also might not cover minor oil leaks, instead only covering serious oil leaks, such as if you need to add oil every month.

Similarly, your warranty provider will likely deny an oil leak claim if you’ve damaged the oil pan or underside of the vehicle since warranties don’t provide coverage for damage caused by wrecks and other accidents. You might also have difficulty getting coverage if your negligence caused the leak. If you forget to get oil changes or haven’t kept up with routine maintenance, the warranty provider may refuse to cover the leak.

What to do if your warranty claim for an oil leak is denied

Even if you believe your oil leak should be covered, your warranty provider may deny your claim. If that happens, you still have options:

• Review your contract: Carefully read through your warranty agreement to verify whether the component or issue should be covered.
• Ask for clarification: Contact your warranty provider and request a written explanation of the denial. Understanding their reasoning can help you build a case if you choose to dispute the decision.
• Request a second opinion: Consider getting a diagnosis from a different certified mechanic. If their findings differ significantly from the first, it may support your case.
• File an appeal: Most warranty companies have a process to appeal claim decisions. Submit documentation such as service records, a second opinion and a written rebuttal.

How much does it cost to fix an oil leak?

Oil leaks can cost anywhere from around $100 to more than $2,000 to fix, according to our research. It generally depends on how serious the issue is. While an oil leak’s associated parts aren’t typically expensive to replace, overall costs can increase depending on how much labor is involved.

It’s also worth noting that determining the cause of the leak can require extensive diagnosis, which can add to repair costs. Still, RepairPal estimates that a typical engine leak inspection costs between $122 and $179 on average.

Customer experiences with oil leak warranty coverage

Some ConsumerAffairs reviewers have had an easy time getting warranty coverage for an oil leak, while others reported their issue not being covered.

For example, James, a reviewer from Virginia, said their oil leak was covered under their warranty and the whole process was smooth.

“I had an oil leak two months ago,” James said. “I contacted Endurance to make sure that was a warranty item that could be covered by them, which it was. [...] They told me what to do when I got to the dealership. [...] It was nice and smooth. And they took care of the warranty issue. They also paid [for] half of the car rental that I had to get to get back home.”

However, Robert, a reviewer from North Carolina, said they had trouble getting their oil leak covered.

“[The] first time I took it in, they found I had an oil leak and it needed oil pan gaskets,” Robert said. “[Endurance] refused to pay for that. Although my warranty says gaskets and seals, they said, ‘That's normal wear and tear.’”
