My 2013 lincoln mkt engine can be turned off while in drive by simply pushing the " push start button". that's right the car turns itself off when in drive if one mistakenly touches the 'push start button' used to start the car! to restart the car one must put the car in park, and apply the brake. this obviously is very dangerous when traveling on any road or highway and will certainly lead to an accident. note: i have found the same symptom in both lincoln and ford cars with the push start button option. i recently drove a ford explorer and flex, both with the push button option and both could cars engine could be turned off while the cars were in drive. it does not take much pressure to cause this failure to occur. in fact a slight glance of your hand or finger on the push start button is all it takes. i have contact lincoln and ford but with no response. your interest in this matter would be greatly appreciated. *tr
