My wife and I purchased a certified used Cadillac Escalade Sport Platinum with 36K miles on it from a reputable dealership near our home. After having the vehicle for less than a week, the engine just lost power suddenly and without notice while our entire family (3 kids) were on our way home. We were able to coast off the main highway and onto a crossing road before it glided to a stop in the middle of an intersection. We were able to get the vehicle towed back to the dealership where they are telling us it needs a replacement engine. I am very concerned with how the event unfolded, and it could have been much worse had it happened where we were not able to get off the road. I am happy GM and the dealership are working quickly to replace the engine, but now I have safety concerns and feel like the vehicle has lost some of its value. Even before I could re-title the vehicle or make our first payment on it. I am reading similar stories and am baffled how GM could produce an engine with such a widespread problem, especially when paying significant money for the vehicle.
