Beware of any “free lifetime powertrain warranty” offers. Ask for the required services that if not done, void the warranty. We were offered one on our Jeep, and they wanted the fluids exchanged more frequently than the manufacturer even recommended. Also, they put them in a “menu”, with other most likely unnecessary services. Your “lifetime powertrain warranty” will cost thousands when the vehicle is paid off in 4 or 5 years.
