We have a Mazda Protege 5 - 2002 model. It has always been a great, reliable car. No problems. Aside from routine maintenance it has never been in the shop! The other day my husband was driving on a highway and the air conditioner stopped blowing cold air, then soon after it began to feel as though he was losing power. He pulled over and we had it towed to a mechanic (who we trust and have patronized for years and through many cars!) He told us the engine and radiator were completely burned up. There were no warning signs. Has anyone experienced anything similar?
