A service contract answers one question: what happens if a covered part fails. It does not answer whether a part is failing, and sales conversations tend to blur the two. Before you decide that a contract solves a problem, decide whether you actually have the problem, and that starts with what the car is doing.

Write down the symptoms you have already seen

Keep a short note of anything the car has done in the last few weeks. A noise that appears only when turning, a warning light that comes on and goes off, a shake at highway speed, or a change in how the engine starts are all useful entries. Write down when you noticed each one, what you were doing, and whether it has repeated. Those notes are the record you will need if you later talk to a shop or a provider.

Separate a current symptom from a future worry

A problem you can already hear or feel is different from a fear that the car might fail someday. If the symptom is present today, a contract will not undo it, and you should have a mechanic look at it before you buy anything. If the only issue is the worry, that is a risk to think about in general terms, and a contract may or may not match it. Both situations deserve a clear head, not a sales pitch.

Ask a technician, not the closer, what the sound means

A person at the point of sale is paid to sell, so ask an independent technician to diagnose any symptom you have noted. The diagnosis tells you whether the repair is likely, how urgent it is, and whether it is normal wear or something more serious. Keep that report with your contract file. Whether a symptom is already present is a question the contract's own terms will address, so read the language on pre-existing conditions rather than relying on anyone's summary.

Use the published pages to test the pitch

Once you know what you are worried about, the material on this site is a useful check on whether a contract matches that worry. Start with the methodology page to see how the comparisons are built, then read the contract a provider publishes before you decide anything.
