Mesa, AZ 85209 told me i needed an engine replaced for a blown spark plug. with over $ 7208.00 spent the won't honor the warranty . They want another 496.45 $ to repair a intake manifold gasket that leaks. Said it's not covered under warranty. NAPA autocare doesnt warranty work done by another shop. When it says NATION WIDE PEACE OF MIND warranty. Don't believe it. I was told they don't . You're on your own for warranty work . Napa auto has no honor. Buyer beware they will cheat you. read full review »
