Just bought a used 2008 Jeep Patriot here in Ohio where I live . Didn’t know to look for issues regarding front sub frame. Seller stated it needed new lower control arm. Mechanic has now showed me that the control arm is fine and showed me the front subframe is nearly rotted through and is what needs replaced immediately . It was manufactured 5/08. Will Jeep do anything for this or am I out of luck ?
