My daughter purchased from a dealer a 20-year-old Nissan Figaro with a full three-month warranty. She returned the car as the power steering was leaking. A power steering leak cure solution was poured into the system that was supposed to stop it. As this did not work, they replaced the power steering with a secondhand unit that leaked more than the original. I complained and was told to return the car, so they could try another used part.

Can this be right? The dealer says he can replace with non-reconditioned used parts. This could go on forever. Can I replace the system at a bona fide garage and present the dealer with the bill? The three-month warranty is well out of date although the system was never repaired in the warranty period. Can he just replace faulty with used until one works ok?
