Q. I was driving my Lincoln Navigator on the highway at about 65 miles per hour and suddenly the car lost power. I muscled my way to the side of the road, fearing that I would be killed, but I got to the break-down lane. I collected my thoughts, started the engine and it has been running fine. I expected this big Lincoln to be my last car, but not quite yet! I’m 78 years old and have never had anything quite like this happen. Even if this issue is fixed, I have lost faith in the vehicle and don’t think I will ever feel comfortable driving it. What should I do?  


A. You should go to the Lincoln dealer, explain what happened and have them check for computer codes but also to see if there any computer updates that need to be applied. Once the problem has been found and the repair completed and fix verified, I personally wouldn’t have any concerns with the vehicle.
