2015 LINCOLN MKZ Electrical System Problems

After reading about the numerous complaints about this vehicles transmission issues I have decided to come here. The PCM and TCM need to be changed in the vehicle. Causing rough shifts from 2nd to 3rd and 3rd to 4th which essentially will cause you to replace the transmission because of the damage it causes. Also constantly having drive control malfunction, check headlamp system messages popping up. There is also horrendous noise from the rear suspension any time you go over any type of anomaly in the road.

The contact owns a 2015 Lincoln MKZ. The contact stated that over the past year, she had replaced the battery on three separate occasions. The contact stated that on each occurrence, the vehicle failed to start up after multiple attempts and the vehicle had to be jumpstarted. The vehicle was started and driven to the dealer for the battery to be replaced. Recently, the contact was informed that the SSM rear gate trunk module may intermittently remain operational causing battery drainage. The dealer repaired the failure but could not guarantee that the repair would fix the vehicle. The manufacturer was notified of the failure and referred her to the NHTSA Hotline for assistance. The vehicle was repaired. The failure mileage was 29,236.

TL* THE CONTACT OWNS A 2015 LINCOLN MKZ. THE CONTACT STATED THAT THE VEHICLE WOULD NOT START. AFTER CHARGING THE BATTERY AND STARTING THE VEHICLE, THE VEHICLE DROVE ROUGH AND WOULD NOT PROPERLY ACCELERATE. THE VEHICLE WAS TOWED TO THE LOCAL DEALER FUTURE FORD LINCOLN OF CONCORD LOCATED AT 2285 DIAMOND BLVD, CONCORD, CA 94520 WHO DIAGNOSED THAT THE ELECTRICAL HARNESS WAS FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT YET REPAIRED. NO ADDITIONAL INFORMATION WAS AVAILABLE. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 62,000.

THE PROBLEM HAPPENING,AND AGAIN TODAY IS THAT THE AIRBAG WARNING LIGHT GOES ON AND THE AIR CONDITIONING STOPS WORKING AND THE POWER WINDOWS WON'T OPEN ON PASSENGER SIDE AND THE RADIO WON'T GO ON AND POWER DRIVERS SEAT MOVE BACK AND FORTH ON ITS OWN WHILE DRIVING!!!! PROBLEMS HAPPEN BOTH WHILE DRIVING AND IN STATIONARY POSITION. THIS HAS HAPPENED OCT 25. 2020. I FOUND OUT LL THIS AFTER STARTING THE VEHICLE.

WHILE DRIVING, SOMETIMES THE HORN COMPLETELY STOPS WORKING, AT THE SAME TIME THE HORN STOPS WORKING I CAN REMOVE MY SEATBELT OR HAVE A PASSENGER NOT WEARING A SEAT BELT AND THE SEAT BELT INDICATOR AND CHIME DOES NOT COME ON, I HAVE BUCKLED AND UNBUCKLED THE SEATBELT TO TRY TO GET THE INDICATOR TO COME ON AND NOTHING HAPPENS. I AM WORRIED THAT THE SEAT SENSORS OR SEAT BELT LATCH ARE DEFECTIVE ALSO THE HORN ISSUE MAY BE ANOTHER UNDERLYING PROBLEM.

SEAT BELT SENSOR DOES NOT COME ON ALL THE TIME WHEN SEAT IS OCCUPIED, HORN DOES NOT WORK ALL THE TIME. I WAS INFORMED THAT THIS COULD BE A MAJOR PROBLEM IF LEFT UNREPAIRED. I CANT SEEM TO GET MY LOCAL LINCOLN DEALERSHIP TO FIX THE PROBLEM WEITHER ITS A MODULE OR SOMETHING ELSE.

IT STARTED MONTHS AGO WITH A STRANGE HUMMING NOISE COMING FROM THE BACK OF THE CAR ON THE RIGHT SIDE ,WHERE THE GAS TANK IS. IT WOULD COME AND GO VERY COUPLE OF WEEKS. MY MECHANIC CHECKED IT OUT AND FOUND NOTHING. ONE DAY, WITH THE HUMMING SOUND VERY LOUD , THE CAR LOST POWER WHILE DRIVING, ALMOST CRASHED. HAD IT TOWED BACK TO THE MECHANIC ,WHO I TRUST AND AGAIN COULD FIND NOTHING. I CALLED A LINCOLN DEALER AND THEY KNEW NOTHING OF A GAS PUMP RECALL. MY MECHANIC LOOKED UP ON EDMONDS AND NOTICED THEIR WAS A RECALL ON FUEL PUMPS FOR THE MKC BUT MY CAR MISSED THE INCLUSION DATE BY A MONTH. SO WE REPLACED THE PUMP.$700. SEEMED TO WORK UNTIL 2 DAYS AGO WHEN I TRIED TO START THE CAR BUT COULDN'T DEPRESS THE BRAKE PEDAL BECAUSE IT WAS DOWN TO THE FLOOR AND THE...

IN UNDER 4 YEARS/50K MILES BATTERY HAS BEEN CHANGED 4 TIMES. EVERY TIME THE CAUSE IS A BAD BATTERY AND NOT A DRAW. THERE IS AN UNDERLYING ISSUE WITH THE MKZ ELECTRICAL ARCHITECTURE. DEALER SAYS THIS IS A COMMON PROBLEM.

IN SUDDEN EMERGENCY SITUATIONS, WHEN ONES REACTION TO HITTING THE HORN TO GET THE OTHER DRIVERS ATTENTION, THE HORN DOES NOT WORK. AFTERWARDS I WOULD TRY THE HORN IN A NON-EMERGENCY SITUATION WHEN ONE HAS TIME TO LOOK, THINK AND PRESS THE HORN BOTTON, LOWER MIDDLE CENTER THE HORN DOES WORK. WITH TWO HANDS ON THE STEERING WHEEL AT 10 O'CLOCK AND 2 O'CLOCK, ONE SHOULD BE ABLE TO USE THEIR THUMBS TO APPLY THE HORN, BUT THAT TAKES WAY TOO MUCH PRESSURE. THE SIDE HORN ACTIVATOR NEEDS TO BE MUCH MORE SENSITIVE. ACCIDENTS, INJURIES AND DEATHS COULD BE AVOIDED IF THE SIDE HORN ACTIVATOR IS MUCH MORE SENSITIVE.

THE REAR BACKUP LIGHT TO LESS THAN ADIQUATE. AT NIGHT WHEN BACKING UP THE LIGHT IS SO DIM THAT I'M UNSURE IF THERE ARE NO OBSTICLES IN THE WAY, LIKE PEOPLE AND CARS. A BRIGHTER LIGHT COULD AVOID BACKING UP ACCIDENTS AND INJURIES AND POSSIBLE DEATHS.

WHILE CAR IS IN MOTION THE AIRBAG WARNING LIGHT SUDDENLY GOES ON AT THE SAME TIME THE AIR CONDITIONING GOES OFF AND WILL NOT GO BACK ON. SIMULTANEOUSLY THE RADIO AND POWER WINDOW AND POWER SEATS AND POWER MIRROR STOP WORKING. TO DATE THIS HAS HAPPEN APPROXIMATELY EIGHT TIMES.

4 TIMES SINCE CAR WAS BRAND NEW I HAVE HAD TO CONTACT DEALER AND CORPORATE LINCOLN ABOUT THE SAME VERY DANGEROUS REOCCURRING PROBLEM. THEY CONTINUE TO NOT BE ABLE TO FIX. THE PROBLEM HAPPENING,AND AGAIN TODAY IS THAT THE AIRBAG WARNING LIGHT GOES ON AND THE AIR CONDITIONING STOPS WORKING AND THE POWER WINDOWS WON'T OPEN ON PASSENGER SIDE AND THE RADIO WON'T GO ON AND POWER DRIVERS SEAT MOVE BACK AND FORTH ON ITS OWN WHILE DRIVING!!!! PROBLEMS HAPPEN BOTH WHILE DRIVING AND IN STATIONARY POSITION. THIS HAS HAPPENED SINCE APPROXIMATELY JULY 2015 THROUGH TODAY AUGUST 2017. DEALER AND LINCOLN ARE BECOMING LESS AND LESS AMICABLE IN HELPING US GET THE CAR REPAIRED AND PROVIDE LOANER VEHICLE EVEN THOUGH IT IS UNDER FULL WARRANTY WITH ONLY 23000 MILES ON IT.

THIS VEHICLE HAS BEEN IN SERVICE 14 TIMES IN 16 MONTHS FOR VARIOUS INTERMITTENT ELECTRICAL AND SENSOR PROBLEMS. IT WAS PURCHASED NEW IN JUNE 2015 AND CURRENTLY HAS 14K MILES. IT HAS SEVERAL MAJOR ISSUES BUT THE TWO SAFETY RISKS ARE: 1) THE DRIVER SEAT IS SUPPOSED TO AUTOMATICALLY RECLINE AND THE STEERING WHEEL ADJUSTS UPWARD TO ALLOW THE DRIVER TO EXIT THE VEHICLE WHEN THE IGNITION IS TURNED OFF. THE SEAT IS SUPPOSED TO RE-ADJUST FORWARD & STEERING WHEEL DOWNWARD TO THE MEMORY THAT THE DRIVER SETS ONCE THE IGNITION IS TURNED ON. TWICE THE SEAT AND STEERING WHEEL WOULD NOT ADJUST TO THE MEMORY SETTINGS. THE SEAT STAYED RECLINED AND THE STEERING WHEEL REMAINED UPWARD. I PUSH THE LEVERS TO MOVE THE SEAT AND STEERING WHEEL MANUALLY IN ORDER TO DRIVE AND REACH THE PEDALS, AND TO SEE ABOVE THE STEERING WHEEL BUT NEITHER WOULD MOVE. I HAD...

IN 20K MILES ENTIRE CAR STOPPED WORKING AFTER IN GARAGE OVER WEEKEND AND NO LIGHTS WERE ON, NO ISSUE WAS FOUND INITIALLY BUT BATTERY WAS CHANGED ONCE IN A NEW CAR IN LESS THAN 2 YEARS. CAN CAN SHUT OFF IN THE MIDDLE OF DRIVING?
