Be very careful when purchasing an after-market warranty. Do your research is the best advice I can give you.
I work at a Ford dealership. The only extended warranties we accept up front for payment are Ford ones.
Any non-Ford after-market warranty repairs must be paid by the customer, and then the customer is responsible for getting reimbursed.
After-market warranty companies are notorious for not paying the claims, for taking months to pay a claim, and for going out of business.
It became a liability for us to accept the risk. You will find that it is not unusual for dealerships to demand up front payment if the extended warranty is not from the manufacturer.
My best suggestion would be to buy the Dodge extended warranty since that is the vehicle you purchased. When purchased from the manufacturer, you will never have to worry about that warranty not being accepted.
True....manufacturer extended warranties are more expensive...but you won't ever be faced with having to pay for your repairs up front and then hope that you will be reimbursed.
If you decide to go with an after-market company I cannot impress upon you enough to do your research about them. I have seen too many customers walk out of here with a $1500 repair bill only to have their extemded warranty company refuse the claim.
