Vehicle turned off while driving. Luckily, I was driving in a parking lot when it happened, therefore, I was not at a high volume of speed. The issue has been confirmed by a dealer. No inspection by manufacturer or others has been conducted. No warning lamps or other messages were noted prior to failure. Issues have been ongoing for about 2 months now.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2014 Lincoln Mks verdict →
