First, a useful distinction
Warranty, service contract, and insurance are not interchangeable.
The warranty that came with your car was part of the sale. A vehicle service contract is optional protection you buy separately. Auto insurance covers risks such as collision, theft, and liability according to the policy. Having one does not mean you have the others.
The Federal Trade Commission explains the difference between auto warranties and service contracts. The Ohio Attorney General makes the same distinction.
Six questions worth asking
Imagine the car is already at the shop.
The best time to understand a service contract is before a warning light comes on. Ask these questions while you still have time to compare.
Who stands behind the contract?
Find the provider and administrator. The company selling the plan may not be the company responsible for claims.
Which repairs can qualify?
Look for the covered components, then read the exclusions. Both lists matter.
What comes out of my pocket?
Add up the plan price, deductible, payment terms, taxes, fees, and costs the contract does not cover.
What could cause a claim problem?
Check the rules for prior authorization, maintenance records, limits, diagnosis, teardown, and preexisting conditions.
Where can I take the car?
Know which repair facilities you may use, whether a network applies, and what happens during an emergency repair.
What if I change my mind?
Read the cancellation window, refund method, fees, mileage calculation, lienholder terms, and state-specific language.
Before adding new protection
See what you already have.
Pull out the paperwork for any manufacturer warranty, certified pre-owned coverage, dealer promise, insurance benefit, roadside plan, credit card benefit, or existing service contract. Paying twice for similar protection may not add much value.
Then think about how long you plan to keep the car, what a large repair would do to your budget, and whether the plan's price and limits feel worthwhile to you. The right answer is personal.
Save the contract, purchase confirmation, maintenance receipts, claim authorizations, repair orders, and written messages in one place. Future you will be glad you did.
For Ohio drivers
This is a regulated written contract.
Ohio law defines a motor vehicle service contract as an agreement, purchased for a separately stated price and lasting for a specific period, that provides or pays for certain vehicle maintenance, replacement, or repair services. You can read Ohio Revised Code section 3905.426 and speak with a qualified professional about your situation.
