I have purchased extended warranties on several cars and never had them pay a penny*. I bought one from Toyota on the Camry Hybrid we bought last year because, frankly, the amount of technology in the car is frightening.
I know full and well that they know that they are charging more for the warranty than they will pay out to the typical customer.
I have a 2018 Ford Flex that will be three years old next month and I have to decide if I want an extended warranty. With Ford my frustration is how short the warranty time period is they offer, only 8 years, which is from the date of sale of the car, so it is really only 5 years. But the mileage it goes to is nuts, like 150,000 miles. I'm looking for 10 years minimum, and much lower mileage. The Flex is a month short of 3 years old and has 11,000 miles on it, so a warranty with 85,000 miles would be more than enough. That's what I have on the Toyota.
*Actually I had one repair on a Dodge with a Chrysler extended warranty that in the fine print of the warranty was not covered. The heater core. And on a Ford, I had the fuel pump go out that the extended warranty denied, but in that case, it was because Ford had a bad batch of fuel pumps and they had a "secret" warranty for 10 years or 100,000 miles on the fuel pump.
