NHTSA Complaint #11536963 — 2017 LINCOLN MKZ

While driving my 2017 Lincoln MKZ 3.0L in March 2023, I experienced a loss of power and then engine stalled, fortunately I was at a stop and was able to re-start the vehicle and limp home, (which was nearby). If this loss of power and then stall would have happened while I was moving in traffic the failure could have lead to a catastrophic outcome including loss of life. It was determined via OBDII analysis conducted by the Lincoln Service department that DTC P0302 was triggered. Upon further inspection by the service department it was revealed that the issue was related to TSB 19-2243, which reads "2.7L/3.0L - Oil Consumption With DTC P0524 And/Or P06DD, Rough Idle, Misfire And/Or White Or Blue Exhaust Smoke - Built On 1-Apr-2016 And Through 1-Jan-2017". Unfortunately, my vehicle was built during this known defect time frame. And the remedy required new cylinder head. The new cylinder head and subsequent parts and labor cost me $3,126.58. This was extremely unfair as my only because my vehicle did not fall within the warranty period or mileage. The vehicle was over 6 years old with 36,934 miles. This very serious failure mode could have resulted in a loss of life if experienced while driving on a highway or any other situation in which the vehicle was mobile and experienced a sudden loss of power in traffic. Further disappointing is that I would estimate that there were many vehicles that experienced the defect noted in the TSB but these were not reported publicly because they were "lucky enough" to fail during the warranty period. My costs should be reimbursed by Lincoln given this was a known defect during the build time frame. And at minimum there should be a safety recall for the vehicles built during the time period noted in the TSB. I will personally never purchase another Lincoln not to mention a Ford, of which I currently have 3 Ford/Lincoln.
