Electrical system

19 reports
“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.”

Service brakes

8 reports1 crash
“I tried to start my car this morning. It would not start. There was a loud popping noise, the headlights started flashing and a red box popped up on the control panel with the words brake failure. It was fine yesterday. There is a recall on the brake hoses. I called the dealership I bought the car from, Oxmoor Ford, Louisville, Ky and they said they don’t service Lincoln products anymore and referred me to Bill Collins Ford. I called them this morning and they haven’t called me back. I do have AAA, so I can have the car towed to the dealership. I need my car, what do I do?”

Air bags

7 reports
“In the middle of June 2024 (about [XXX]), my wife was driving her car, and pressed the horn button to warn a driver who had pulled out right in front of her. The horn failed to sound, and has not worked since then when pursuing the horn button. The horns themselves do sound when pressing the key fob to locate the car. Pressing the horn button has never worked since the time of this report, and several instances have occurred with other drivers needing to be forewarned of hazards. The problem has been verified by the husband, but not yet by the dealer, police or insurance representative. Sincerely, [XXX]”

“TRANSMISSION MAKES UNUSUALLY LOUD REVVING NOISE WHEN THE GAS ENGINE TAKES OVER FOR THE ELECTRIC MOTOR. IF YOU ARE ON AN ENTRANCE RAMP TO A FREEWAY AND APPLY 1/2 PEDDLE OR MORE TO MERGE ONTO FREEWAY, IT HAS A VERY NOISY REV (TRANS) NOISE. I HAVE BEEN APPRAISING CARS FOR 25YRS IN THE RETAIL AUTO BUSINESS AND I HAVE DRIVEN OTHER MKZ HYBRIDS AND THEY DON'T MAKE AS MUCH NOISE AS THIS CAR MAKES”

Engine

“The catalytic converters(2) failed and need replacement. My mechanic diagnosed the problem and agrees with the scan code that was reported, a P0430. The check engine light is constantly lit and cannot be turned off with this fault code, according to my mechanic erasing the code will just bring it back shortly, and I have witnessed this. I have a document from Ford Motor Co. that shows my car, Lincoln MKZ, the build date from 2013-2015(1/24/2015), the Assembly plant of Hermosillo, saying that the dealer should replace the cats at no charge to the customer. Yet the dealer and FoMoCo say my cars VIN is not in the range for this repair. Why?”
