While in cruise control with lane assist on the car slowed down immediately with no cars or any obstacles around. This has happened three times. I’m at the point where I don’t trust it.
The contact owns a 2019 Lincoln Nautilus. While the contact's father was driving approximately 25-40 MPH, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. Additionally, the contact stated that the transmission shifted hard, and the vehicle shuddered and jerked abnormally while driving. The contact stated the failure had occurred while her father was driving at a slow speed. The contact referenced an unknown recall; however, the VIN was not associated with the recall. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was not made aware of the failure. The failure mileage was unknown.
This car has had continued issues with gear shifting up and down. It was bright into a dealership last year to fix the recall issues, however, it seems to have made it worse. The acceleration suddenly drops when going up a hill and revs loudly, pushing the pedal nearly to the ground unexpectedly. It seems to get stuck between gears both up shifting and down. It's nearly caused accidents.
Was slowly entering my garage when there was a sudden acceleration. Put on brake but not before my car went thru the back garage wall and fell about four feet down before hitting the patio floor. It traveled across the patio and went over some furniture on the deck. The air bag never went off. The transmission had been very temperamental before this happened. I was not injured but could have caused a real issue had I been in traffic. I love the car but I personally will not drive it again. It is a 2019 Lincoln Nautilus.
The automated parking assist function malfunctioned. I will attach the video. Lincoln claims that the auto functioned as designed.
The backup warning at times doesn't alert you to cross-traffic. Also the backup camera image is terrible in the daytime and at night is almost impossible to see the image quality is so bad.
I WAS DRIVING IN THE LEFT LANE, OF A MULTI-LANE INTERSTATE. I HAD THE CRUISE CONTROL ON. THERE WAS A STANDARD-SIZED DUMP TRUCK IN THE LANE NEXT TO MINE, UP AHEAD. THE ROAD WAS STRAIGHT, WITH ONLY A SLIGHT INCLINE. THERE WERE NO VEHICLES IN FRONT OF ME FOR AT LEAST A HALF OF A MILE OR MORE, AND ALL TRAFFIC WAS RUNNING SMOOTHLY. AS I PASSED THE TRUCK, THE CAR SUDDENLY JAMMED ON THE BRAKES. I'M NOT SURE, BUT I EITHER INSTINCTIVELY HIT CANCEL ON THE CRUISE CONTROL, OR I PUT MY FOOT ON THE BRAKE. EITHER WAY, IT ARRESTED THE HARD BRAKING SITUATION. I NOTICED THAT THE SUN WAS AT MY 2 O'CLOCK POSITION, AND AS I BEGAN TO PASS THE DUMP TRUCK, ITS' SHADOW WAS THROWN ONTO MY VEHICLE. I'M SURMISING THAT PERHAPS THE COMPUTER THOUGHT THE SHADOW WAS AN OBJECT AND TOOK ACTION. REGARDLESS, THIS WAS AN ENORMOUS SAFETY ISSUE. HAD THERE BEEN A VEHICLE CLOSE BEHIND ME, IT WOULD HAVE CERTAINLY RESULTED IN A MASSIVE ACCIDENT. IF THIS CAR CONTAINS AN EVENT RECORDER, I WOULD BE HAPPY FOR YOU OR LINCOLN TO DOWNLOAD THE DATA. I HAVE LOST ALL CONFIDENCE IN THE "SAFETY" FEATURES OF THIS CAR, PARTICULARLY THE ACTIVE BRAKING SYSTEM / COLLISION AVOIDANCE SYSTEM. I HAVE NOTICED IN THE PAST, THAT IT WILL JAM ON THE BRAKES AS IT'S COMING AROUND A CURVE ON A MULTI LANE ROAD, WHEN IT DOESN'T "SEE" THAT THE CAR AHEAD OF ME, IS ACTUALLY IN ANOTHER LANE. I HAD LEARNED TO ANTICIPATE THAT BEHAVIOR, BUT NOT THE BEHAVIOR EXPERIENCED YESTERDAY, WITH THE ALL-OUT PANIC BRAKE. IF THERE IS ANYTHING I CAN DO TO HELP INVESTIGATE THIS INCIDENT, PLEASE CONTACT ME ASAP.
LOST POWER STEERING IN MIDDLE OF DRIVING. ALMOST GOT INTO SERIOUS ACCIDENT.
WHILE DRIVING THE 2019 LINCOLN NAUTILUS ON A 4 LANE HIGHWAY WITH ADAPTIVE CRUISE CONTROL AND LANE CENTERING ON, THE CAR ALL OF A SUDDEN TURNED INTO THE NEXT LANE. IT DOES THIS BOTH TO THE RIGHT AND THE LEFT. I WAS ON THE PHONE WITH BOTH MY MOTHER AND THE LINCOLN SERVICE MANAGER ON SEPARATE INCIDENTS WHEN IT OCCURRED. ALSO, I TOOK IT ON A TEST DRIVE WITH THE LEAD MECHANIC AND IT DID THE SAME THING TO HIM TO THE RIGHT, RIGHT WHERE OUR VETERINARIAN OFFICE IS LOCATED. CENTER LINE WAS STILL THERE. AFTER THEY HAD THE CAR FOR A FEW DAYS, AND A CONVERSATION WITH THE GENERAL MANAGER, THEY DETERMINED THAT IT WAS WORKING AS DESIGNED, THEY CHECKED OTHER NON-NAUTULIS VEHICLES AND FOUND THE SAME THING. THEY TOLD ME THAT IT WOULD NOT HAPPEN ON AN INTERSTATE. I WAS SHOCKED. THERE IS NO DIFFERENCE BETWEEN A 4 LANE HIGHWAY AND AN INTERSTATE. I AM A RETIRED NAVY OPERATIONAL TEST PILOT, AND WE WOULD NEVER ALLOW THIS TO BE GIVEN TO THE FLEET OPERATORS. I CHECKED THE OPERATORS MANUAL ON PAGE 239. HERE IS WHAT IT SAYS: THE SYSTEM MAY NOT CORRECTLY OPERATE IN ANY OF THE FOLLOWING CONDITIONS: ' YOUR VEHICLE IS NOT CENTERED IN THE LANE. ' THE LANE IS TOO NARROW OR WIDE. ' THE SYSTEM DOES NOT DETECT AT LEAST ONE LANE MARKING OR WHEN LANES MERGE OR SPLIT. ' YOU SWITCH THE DIRECTION INDICATOR ON. ' LIMITED STEERING TORQUE INPUT IS APPLIED. ' AREAS UNDER CONSTRUCTION OR NEW INFRASTRUCTURE. ' WHEN MODIFICATIONS TO THE STEERING SYSTEM HAVE BEEN MADE. ' WHEN USING A SPARE TIRE. NOTE CONDITION ABOVE: ' THE SYSTEM DOES NOT DETECT AT LEAST ONE LANE MARKING OR WHEN LANES MERGE OR SPLIT AT THE TIME OF THE INCIDENTS THERE WERE TURN LANES ON EACH SIDE OF THE CAR WITH SMALL OPENINGS TO MOVE INTO THE TURN LANE. THE CENTER LANE MARKINGS WERE ALWAYS THERE.
ON MULTIPLE OCCASIONS THE HILL START ASSIST AND FORWARD COLLISION WARNING BOTH FAILED AT THE SAME TIME. FOLLOWING THAT, WHEN RESTARTING THE VEHICLE, THE INSTRUMENT CONTROL PANEL FAILS TO ILLUMINATE. THIS DISABLES THE VIEW OF ANY OF THE CONTROL PANEL NOTIFICATIONS, ALONG WITH THE SPEEDOMETER. WHILE THE INSTRUMENT CONTROL PANEL IS DISABLED, THE SUPPLEMENTAL RESTRAINT FAILURE NOTIFICATION APPEARS SEVERAL TIMES. RESTARTING THE VEHICLE DOES NOT SEEM TO REMEDY THE PROBLEM, IT TYPICALLY TAKES 24 HOURS BEFORE THE FUNCTION RETURNS.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
