Incident Summary - Vehicle Fire Date of Incident: Thursday, September 4, 2025 Context: I was driving to a scheduled service appointment for my car at Murgado Lincoln Dealership of Chicago Events Leading Up to the Fire While driving, I heard loud metal noises coming from under the hood. The sound was either metal pieces falling off or grinding/chomping metal against metal. Concerned by the noises, I pulled over to the side of the road. Smoke and Fire Once stopped, the car began emitting gray smoke, which quickly turned into black smoke. The black smoke entered through the dashboard, filling the interior cabin. I realized the vehicle had caught on fire. Immediate Actions Taken I quickly gathered personal belongings from inside the car. …
I purchased my 2017 Lincoln MKZ Select on November 11, 2024. The vehicle was determined to need a new engine, per Murgado Lincoln of Chicago. They had my car for over 48 days while putting in a new engine. After this was completed the car had to be sent back due to a mistake the mechanics made by not attaching a gasket properly. After this, I began experiencing odd noises underneath the hood and throughout the vehicle; delayed timing belt in both acceleration and deceleration, and so forth. I was then involved in a hit-and-run car accident (not my fault). All side airbags deployed and my passenger side rear wheel is destroyed. I had this car assessed just a few days ago by a certified Auto Care Company who said I needed a completely new transmission and that this car is not street legal at the moment... insurance is not helping me at all.

I purchased a 2017 Lincoln MKZ Select which has been a continuous source of mechanical problems. After recently having a new engine installed, the vehicle has now developed significant transmission issues, making it unsafe and difficult to drive. Despite being sold this car under the assumption it was reliable, I am struggling with costly repairs and reduced functionality, effectively driving a "lemon." I believe the vehicle's condition and recurring failures qualify it for protection under consumer lemon laws or warranties, and I am seeking resolution or compensation due to these defects that have severely impacted the vehicle's usability and my safety.
