Took my 2005 F150 4x4 to the Ford dealership because it was making a grinding noise near the front tire. Come to find out the IWE solenoid is bad along with the lower control arm. I purchased the truck from a nearby Nissan dealership and just so happened to buy a CNA warranty since the truck had 90k miles. The ford dealership quoted $680 for the repair but my CNA warranty is ACTUALLY going to cover the cost. They also have included a rental car for $35. I've heard a lot of negative input when it comes to aftermarket warranties and because of that I have never purchased one with my used vehicles. Just something to keep in mind.
