Was driving down the highway and car started to slow down. No temperature light came on but car started to smoke a little underneath hood. Stopped car at an empty lot, and had it towed to a garage. They said my engine had overheated and needed a new head gasket. It had previously had a head gasket put on it about a year ago, so this would have been the second one. Mechanic advised me not to have a second head gasket job but instead advised me to get another engine for the car.
