2012 Lincoln MKX problems

“Recalled master cylinder brake booster was repaired at the dealership under the recall approx 4 or 5 years ago. The same issue has began again. Out of nowhere while braking, the pedal will become soft and press to the floor. During this time, the car will not slow down. This is resembling a defective part.”

“DRIVER SIDE FRONT DOOR SENSOR SAYS CAR DOOR IS OPEN EVEN WHEN DOOR IS FIRMLY SHUT. CAUSES DOORS NOT TO LOCK, INTERIOR AND PUDDLE LIGHTS REMAIN ON, DRAINS BATTERY, DOORS WON'T LOCK EVEN WITH CAR IN MOTION. Severe Rust problems under carriage Air Bag light remains on”

“The contact owns a 2012 Lincoln MKX. The contact stated while driving at various speeds, the accelerator pedal was depressed but the vehicle failed to respond. The All-Wheel Drive (AWD) warning light and the power train warning light were illuminated. The contact stated that he veered to the side of the road and turned off the vehicle and waited for 15-20 seconds. The contact then continued driving; however, the failure recurred increasingly. The vehicle was taken to an independent mechanic who test drove the vehicle and informed the contact that they could not duplicate the failure. The dealer and the manufacturer were notified of the failure and informed the contact that the vehicle could not be repaired under an unknown NHTSA Campaign because the VIN was not included. The vehicle was not diagnosed or repaired. The failure mileage was approximately 97,400.”

“MY 2012 LINCOLN MKX IS EXPERIENCING AN ISSUE WITH THE BRAKES MAKING IT ALMOST IMPOSSIBLE TO STOP. THE BRAKE PEDAL IS REQUIRING EXTREME FORCE TO STOP AND GOES ALL THE WAY TO THE FLOOR, FOLLOWED BY A HISSING AIRY SOUND. THE VEHICLE WAS TAKEN TO THE LINCOLN DEALER WHO DIAGNOSED THE ISSUE AS A BRAKES AND CHARGED ME $900. AFTER PICKING UP THE VEHICLE AND TEST DRIVING IT, THE PROBLEM PERSISTED. AFTER RE-DIAGNOSING THEY POINTED THE FINGER TO A HYDRAULIC CONTROL UNIT. THIS ISSUE POSES GREAT DANGER AND THE INABILITY TO STOP WITHOUT LITERALLY STANDING AND APPLYING FORCE TO THE BRAKES. I HAVE HAD TO STOP DRIVING THE CAR BECAUSE WHEN COMING TO A STOP AT ANY SPEED, THE FORCE NEEDED TO STOP AND A COUPLE CLOSE CALLS WITH RAMMING IN THE BACK OF SOMEONE, THE CAR IS JUST TOO DANGEROUS. ADDITIONALLY, I'VE HAD OTHER ISSUES WITH THIS CAR WHERE THE TRUNK WILL NOT STAY OPEN. IT DOES NOT DETECT A PERSON PUTTING THINGS IN THE TRUNK AND I'VE HAD TO RUN AND PUSH IT UP TO SAVE A KID WHO WAS LOADING SPORTS EQUIPMENT.”

“Entering I-294 express ramp, vehicle was not accelerating beyond 40mph. then as I entered highway it shut down completely. I coasted to the right shoulder. The dash displayed a "low oil pressure" alert. So I did not attempt to restart the car. When I had it towed home, I checked the oil level and it was full. Nothing like this happened before. The vehicle is almost 12 years old with 167,000 miles. Had this happened in traffic on the expy, I could have been creamed by other cars or a truck. I am going to the dealer today to investigate but this seems like an anomaly where the engine shuts down because the computer thinks there is a catastrophic failure that is not really happening.”

“The contact owns a 2012 Lincoln MKX. The contact stated that the brake pedal would depress to the floorboard without warning. The contact took the vehicle to the dealer and the brake master cylinder was replaced; however, the failure persisted. The vehicle was taken back to the dealer where it was then diagnosed with a defective ABS system; however, the part for the repair was on backorder. The manufacturer was also notified of the failure and provided the same information as the dealer. The contact was referred to the NHTSA Hotline for assistance. The vehicle was not repaired. The failure mileage was approximately 130,000.”
