What Is Wear and Tear?

Wear and tear refers to the gradual deterioration of vehicle components through normal use over time. It's a simple idea, but it's one of the most important concepts to understand when working out what a car warranty does — and doesn't — cover.

Why Does Wear and Tear Matter?

Every vehicle contains parts that are designed to wear down naturally as they're used. Certain friction materials and consumable components are expected to need replacement at some point during a car's normal life — that's simply how they're engineered to work. Because this kind of deterioration is expected rather than unexpected, warranties commonly exclude it. Cover is generally there to protect against genuine mechanical or electrical failures, not the predictable running costs of car ownership.

Wear and Tear vs Mechanical Failure

The distinction between the two isn't always clear-cut. One component might deteriorate gradually and predictably, while a related part suffers a sudden, unexpected mechanical failure. Warranty providers will generally assess the actual cause of a problem against the specific wording of the policy — which is why two seemingly similar failures can sometimes be treated very differently.

Examples

Depending on the policy, items commonly subject to wear-and-tear exclusions can include:

• Brake components
• Clutch components
• Belts
• Wiper components
• Tyres
• Friction materials

This list isn't universal — specific exclusions vary between providers and between individual policies, so it's always worth checking the detail rather than assuming.

Why Read the Policy?

A term as simple-sounding as “wear and tear” can have a significant impact on whether a claim succeeds. Before purchasing cover, it's worth checking exactly how a policy defines and treats wear and tear, since the wording can vary considerably between providers.

If you're ever unsure whether a repair is likely to be covered, the safest step is to contact your warranty provider before authorising any work — rather than finding out the answer after the bill has already been paid.
