A vehicle or home service contract promises to cover certain failures, and it also leaves some parts of the covered item with the owner. The owner side is often the part buyers discover after their first claim. This guide is about maintenance and ownership: what it takes to keep a covered item working, and how to find the parts the contract expects you to replace yourself.

Wear items are a separate category

Many contracts separate failure from wear. A failure is a part that stops working through a defect or breakdown. Wear is the gradual loss of a part that is built to be used up, such as brake pads, tires, wiper blades, belts, filters, and fluids. Some contracts exclude wear outright. Others cover a wear part only when its wear causes damage to a covered part. The wording decides which, and the same part can fall on either side from one contract to the next.

Find the wear list before you assume

Ask for the full list of wear items in the contract form, not the sales summary. Check whether the list is a closed list of named parts or a general phrase such as normal wear and tear. A general phrase leaves room for disagreement, so ask the seller and the provider in writing how they read it. Keep the answer with the contract.

Ask who sets the maintenance schedule

Many contracts require routine service at intervals the manufacturer publishes, and a missed service can give a provider grounds to refuse a claim. Ask which schedule applies to your item, where it is published, and what proof you must keep. Ask whether a shop you choose must be certified or approved, and whether any upkeep task is yours to do at home.

Ownership moves with the item

When you sell, lend, or move the covered item, the contract may end, transfer, or continue on a new form. Ask what happens to the upkeep duties in each case. The point is to know the answer before the change, not after it.

What this guide does not do

This guide explains the general pattern. It does not state what any company's contract covers, and it does not restate any state's rule. The state pages on this site name the regulator and the statute for each state and say which rules this edition has read. Check the page for your state, then compare it with the form you were given.
