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.

Pick MANUFACTURER warranty if your car is under OEM warranty now (best discount window) and you plan to keep it 6+ years.

Pick Third-Party Warranty (Endurance, CarShield, Olive)

Pick THIRD-PARTY warranty if your car is past OEM warranty already, has high miles, or you want to choose your own repair shop.
