Are third-party warranties a scam?

Not categorically — but quality varies wildly. Reputable providers (Endurance, Olive, Protect My Car, CARCHEX) have BBB A+ ratings and reasonable claim-approval rates. Avoid providers with high BBB complaint counts, unverified addresses, or unsolicited robocall sales. The 'extended car warranty robocall' meme is real and refers to a small subset of bad-actor providers.

Can I buy a manufacturer warranty after I leave the dealer?

Yes — most OEMs let you buy the extended manufacturer warranty up to a year after purchase, often online without dealer F&I markup. This is the loophole: skip the F&I pitch, buy the same warranty directly from the manufacturer 30–60 days later for 30–50% less.

Does my new car already have a warranty? Why would I need another?

Yes — every new car has a factory bumper-to-bumper (typically 3 yr / 36k mi) and powertrain (5–10 yr / 60–100k mi). The extended warranty starts when these expire. The decision tree is: 'Will I keep the car past the factory warranty?' If yes AND the car brand has high out-of-warranty repair costs, extended coverage makes sense.

Manufacturer Extended Warranty vs. Third-Party: Which Is Worth Buying?

Dealer F&I sells the manufacturer warranty at 200–400% markup. Third-party providers (Endurance, CarShield, Olive) underwrite identical coverage for less. The hidden tradeoffs.
