The engine of my 2021 Lincoln Aviator with only 79,403 miles has failed, leaving myself and my family stranded on the side of a very busy interstate in another state far from home. There were absolutely no warnings given before the engine acted as if it had a significant loss of power. Shortly afterwards, very heavy and foul-smelling smoke started coming out of the tail pipe. Had the vehicle transported to a local shop to my home. The car will start and immediately start smoking and running like crap. When you put it in gear it will barely move on it's own power.

Powertrain malfunctioning. The vehicle has had multiple neutral out (not reacting) when the accelerator is applied. Occurring in the middle of an intersection 3 times. Stuck in the middle of the intersection has resulted in two (2) cases of almost being hit by an oncoming vehicle. Pulling into traffic from a stop sign and losing the accelerator another time resulting in traffic breaking hard to avoid an accident. Recently while in cruise control on the highway driving 79 MPH, the vehicle suddenly shifted into what had to be the lowest gear lunging passengers forward and slowing to an unacceptable speed for the highway. Almost initiating being hit from the rear by a tractor trailer and just making it off of the shoulder to safety. This may be the result of service bulletins 22-2145 or SSM 50529. The dealer has stated they cannot reproduce the problems but are aware of the issues and Service Bulletins have been released. No warning lamps have come on when these issues have occurred. Vehicle has been into dealership multiple times. Service Managers had said they are working with Lincoln Engineers to remedy the problem. So far a separator plate and a valve has been replaced, which has not resolved the problem This happens intermittently, but when it does it causes what could be a severe safety issue. Currently the vehicle is in the dealership with no remedy, and has went in if for this issue multiple times. This has been going on for the past six (6) months.

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.
