I normally would agree about the extended warranty thing. But my wife and I bought one on our 2018 Durango R/T that we bought used. We bought the Mopar MaxCare for it strictly for the electronics. We figured one failure of the nav/radio system and we would be close to even on money, two failures and we are golden lol. Our 2015 Journey had two nav units replaced in it under warranty in just two years. But because we bought the extended warranty the system in the Durango has been flawless now for 18 months or so.

Also having extended warranty keeps me from doing things like changing the camshaft, and other modifications I shouldn't do to my wife's car.
