Dodge Caliber, had one fail, RockAuto'ed one. Easy to swap out.
RamPromaster company ride, CEL came on, bad miss, failed coil pack. Car was in the shop for a week, excuse was the Fiat coil pack came from Italy.
Chrysler T&C, failed coil on the rear bank gave a CEL. Had all plugs and pack replaced, repair shop said all other coils tested fine. I don't know how coils are tested, took their word on it. And I wasn't going to be the one digging into the rear bank. A man needs to know his limits.
As I'm thinking, all were FCA products that had coils go boink.
