Insurance companies know all about A/M parts. The problem is that consumers are not educated about how insurance companies reserve the right to use alternative parts based on the policy that the owner chose. People will always complain if you don't pay of anything other than new OEM parts from the dealer. Anything less and everyone complains that the insurance company is ripping them off. If using only genuine OEM parts is that important for someone, they should spend the time to research the policy prior to accepting it. If the parts are safe and the insurance companies will stand behind them, there shouldn't be an issue. Explain how aftermarket parts are counterfeit? For example, Visteon manufactures radiators and other parts for Ford. The radiator is stamped Visteon. That exact radiator, with same stamp is also available aftermarket for 30%-%40 less. What's the difference? Why should insurance companies pay a rediculous mark-up for the same identical part?
