NHTSA complaint #11457309

Owner complaint summary

In regards to my brand new 2021 Lincoln Aviator Reserve (4181 miles): 2.23.22- Driving home on a very narrow, winding road when my car unexpectedly started to vibrate/shake. There were no alerts and no warning lights that came on. Fortunately, I was coming up on one of the very few turnouts available. As I started to pull over the car completely shut off (completely died). Luckily, I made it off of the road or I would have been stuck in the middle of the road on a blind corner as the car would not restart. It just kept displaying "Full Accessory Power Active" but would not do anything. The car was towed back to the dealership who informed me the next day that the engine had completely seized and they would have to replace the engine. One of the piston rods was bent to a 90 degree angle. I got it back on a Saturday afternoon(3.12.22), drove home from work, took my kids to/from school Monday, then drove to work Tuesday morning. On my way to work (which is only 3 miles from home) my car started to vibrate again but I was able to turn off the highway onto a side road and the vibrating stopped. Thankfully, it did not die in the middle of the highway and cause an accident. I continued on down the street and again the vibrating started. As I pulled up to a stop sign the car completely died and would not start. I waited a few moments and tried again and it started. I was able to make it the last less than quarter of a mile to work while it vibrated then died yet again as I pulled into my parking spot. My fiancé came later in the day and started the car. It was making a loud knocking noise so we shut if off and called dealer again. It was towed back for another new engine. As of today, they are still working on "repairing" the brand new death trap. Lincoln doesn't seem to think it's a big deal and thinks the second new engine will fix the issue. Hopefully it doesn't kill me first. This is worth investigating. Like I said, this car is a death trap.
