2021 LINCOLN AVIATOR Engine Problems

1.) Exhaust System Failure (Flex Pipe / Catalytic Converter) The vehicle’s exhaust system—specifically the flex pipe connected to the catalytic converter—cracked and malfunctioned. This component is available for inspection upon request. As a result of the failure, exhaust fumes entered the cabin, creating a significant safety risk due to potential exposure to carbon monoxide. Prior to the failure, I noticed a persistent rattling noise at low speeds and while the vehicle was idling. The issue was inspected and confirmed by the dealership; however, I was informed that the repair falls outside of warranty coverage. I would like to know if this falls under safety hazard for emissions. 2.) Sunroof Glass Shattering Incident While driving, the sunroof glass suddenly shattered and appeared to implode outward. According to the dealership technicians, this may have been caused by thermal stress or frame-related tension. The glass is no longer intact but the remaining components...

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...

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...
